Discover how these plates are empowering the next generation of projects in the chemical, nuclear power and offshore engineering industries. Explore the manufacturing challenges they present and the immense advantages they offer.

The demand for materials capable of withstanding extreme environments, such as high pressures and highly corrosive chemicals, as well as decades of service life, continually pushes the boundaries of manufacturing. Titanium steel composite plates have long been the gold standard for critical applications, combining titanium's corrosion resistance with steel's structural strength and cost-effectiveness.

However, as engineering projects grow in scale and ambition, the materials used to construct them must also evolve. A new generation of metal laminates is emerging in the form of ultra-thick titanium-steel composites, exemplified by 8 mm thick titanium layers over 450 mm thick steel backing plates.

This represents a quantum leap, not an incremental improvement. Let's examine the significance of this specification and explain why it is reshaping heavy industry.

Why such thickness? Engineering necessity:

The '8+450 mm' dimensions are not arbitrary; they directly address specific and demanding engineering challenges.

Exceptional corrosion resistance and longevity: An 8 mm pure titanium coating is extremely thick for a cladding material. This provides formidable corrosion resistance, enabling the material to withstand severe chemical erosion for 30, 40 or even 50 years without risk of failure. This is critical for applications such as:

Large chemical reactors: Their walls must withstand high pressure and temperature while resisting highly corrosive substances such as acids and chlorides.

Flue gas desulfurisation (FGD) systems in major power stations: These systems handle large volumes of abrasive and corrosive slurries.

Exceptional structural integrity: 450 mm carbon steel bac king provides the immense mechanical strength required.

Nuclear power plant components: Pressure vessels, reactor internals and containment systems, in which wall thickness is critical for safety, radiation shielding and withstanding immense working pressures.

High-pressure process vessels: Used in the oil and gas, petrochemical and hydroelectric industries.

Critical marine and offshore structures: Components for offshore platforms or ship hulls that are subjected to extreme ocean forces.

Ultra Thick Clad Plate

Manufacturing marvels: How is this achieved?

Producing composite plates of such thickness is an advanced engineering feat. The most common and effective method is explosive welding.

Explosive welding (EW): This process involves placing a titanium plate (the 'composite plate') parallel to a thick steel plate (the 'backing material'). A precisely calculated explosive charge is placed on top of the titanium plate. Upon detonation, the explosive energy propels the titanium plate through the gap and strikes the steel surface at an extreme velocity and angle.

This impact generates a jet stream that cleans and presses the surfaces together under immense pressure, forming an atomic-level metallurgical bond.

This creates a unique wavy interface that ensures a strong, durable connection without compromising the properties of either metal.

Overcoming the challenge: bonding steel plates of this thickness requires precise control of explosive energy. Too little energy will fail to form a bond across the entire interface, while too much could damage the materials. Accelerating the 8 mm-thick titanium layer also demands immense energy to achieve uniform bonding. This process requires complex computer modelling and decades of specialised expertise.

Key advantages of this ultra-thick composite plate:

Cost-effectiveness: It delivers performance comparable to pure titanium at a fraction of the cost, yielding significant savings on materials for large-scale projects.

Reliability: The explosion welding process creates a permanent, 100% metallurgical bond with exceptional mechanical properties, including high shear strength.

Performance optimisation: Engineers benefit from a thick, corrosion-resistant barrier on one side and an exceptionally robust structural material on the other.

Design flexibility: Despite their large size, the plates can be formed, welded using specialised techniques, and machined into final components, offering tremendous freedom when designing large structures.

Redefining Applications:

The arrival of reliably produced, ultra-thick composite plates opens up new possibilities:

Next-generation nuclear reactors: (e.g. small modular reactors (SMRs) and fusion reactors).

Giant chemical processes for large power plants;

High-pressure, high-temperature (HPHT) subsea equipment for deep-sea oil and gas extraction;

Specialised heavy machinery for mining and metallurgy.

Titanium Steel Thick Clad Plate

Layers upon layers, building the future together.

The 8+450 mm titanium steel clad plate is more than just a piece of metal; it embodies the ingenuity of the human race in the field of materials science. It demonstrates our capacity to overcome the world's most challenging engineering obstacles by combining the ideal properties of various materials in a creative manner.

As industries continually pursue larger, safer and more efficient solutions, these ultra thick composites will become the true pillars of our planet's most critical infrastructure.

C Purlins VS Z Purlins

2025-09-19 - tags：C Purlins VS Z Purlins Z section purlins Composite Floor Deck Galvanized Z purlins

z and c purlins

A purlin is a critical horizontal structural component designed to provide intermediate support for roof systems. These load-bearing members typically span between primary framing elements (such as walls or rafters) to:

☆Distribute roof loads

☆Prevent rafter deflection

☆Create stable mounting surfaces for cladding

Common materials include:

☆Steel (Z/C purlins for metal buildings)

☆Timber (traditional wood-frame structures)

☆ Composite (engineered hybrid systems)

Modern applications range from industrial warehouses to residential roof reinforcement, where purlins enhance structural integrity while optimizing material usage.

z and c purlins

Currently, purlin manufacturers typically produce two main types of purlins – Z purlins and C purlins.

Let's first examine their specific characteristics.

C Purlin	Z Purlin
C purlins are shaped like the C alphabet and are primarily used to support walls and floors. Their smooth inner surface ensures seamless cladding attachment, while their structural simplicity makes them ideal for basic span constructions. These purlins are also perfect for simple span construction.	Z purlins is a distinctive Z-shaped profile, formed from cold-rolled steel sheets for maximum efficiency. Compared to traditional hot-rolled angles, they reduce material usage by 50% while maintaining superior strength-to-weight ratios, making them ideal for cost-effective structural framing.

z and c purlins

What is the differences between C and Z Purlins?

Usage	C purlins are used to form wall and floor joists in building shell structures. Z purlins are employed for roof and wall joists in building envelope construction.
Angles	C purlins feature a standard 90-degree angle, while Z purlins are designed with acute angles (typically 60-85 degrees). This angular distinction makes Z purlins more adaptable and flexibility than C purlins.
Overlapping	Z-purlins can be continuously lapped, whereas C-purlins cannot. Therefore, Z-section purlins are the preferred choice for metal buildings with larger spans.
Roof Sloping	For roofs with minor slopes, Z-section purlins exhibit a slightly greater difference in bending modulus compared to C-section purlins. However, as the roof pitch increases, the bending section modulus of Z-purlins symmetrically enhances along the slope direction. Consequently, Z-section purlins are more suitable for steeply pitched roofs.
Support	Z-section purlins are typically installed between roof panels to provide structural support, whereas C-section purlins are used as secondary beams for floor slab reinforcement.
Strength	Z-section purlins demonstrate superior load-bearing capacity, making them ideal for supporting heavy-duty structures, while C-section purlins offer relatively lower strength. Consequently, Z-purlins are the preferred solution for roofing systems and buildings requiring greater load capacity. These structural components are commonly implemented in agricultural and industrial construction projects.
Installation	C-section purlins offer simpler installation, while Z-section purlins require greater effort and technical expertise. This makes C-purlins an excellent choice for single-span steel frame roof structures.

z and c purlins installation

In summary,C purlins offer easier installation and cost efficiency for simple structures, while Z purlins provide superior strength and load capacity, ideal for large-span roofs. Their overlapping capability makes Z sections better for sloped designs. Choose C purlins for basic framing and Z purlins for heavy-duty or complex architectural needs.

z and c purlins

Beyond roof and wall support, steel purlins reinforce mezzanine floors, creating extra space cost-effectively. Paired with beams, they form a sturdy framework, transferring loads to primary beams,just like in roofing systems,ensuring safety without expensive construction.

What's the Difference Between the Metal Floor Deck and Roof Deck?

2025-09-19 - tags：Corrugated Metal Decking Metal Deck Roof Metal Deck Roofing Sheets

As we all know ,metal decking has become essential in modern construction, with composite floor decks and non-composite roof decks being the most common types. While both use corrugated steel sheets, their designs differ to handle structural loads versus weather protection. Understanding their distinct roles ensures optimal performance in steel-framed buildings.

What is metal floor deck?

Metal floor deck is composite metal floor deck, is a structural system consisting of profiled steel sheets (typically 0.8mm-1.5mm gauge galvanized steel) that serves as permanent formwork and tensile reinforcement for cast-in-place concrete slabs. The deck's trapezoidal ribs feature embossed patterns to create shear bond with concrete, enabling composite action that enhances load-bearing capacity (typically 3-7kPa for offices). This system provides fire resistance through concrete cover (60-120mm), eliminates traditional formwork, and allows faster construction (30-50% time savings versus conventional methods). Its lightweight nature (15-25kg/m²) reduces structural steel requirements while maintaining deflection control (L/180 to L/360 spans). Widely used in high-rise buildings, the system achieves vibration performance (4Hz+ natural frequency) and accommodates MEP integrations through pre-punched service holes.

What is metal roof deck?

Metal roof deck is non-composite metal roof deck, is a structural roofing component made from corrugated steel sheets (typically 22-20 gauge galvanized or painted steel) designed to provide diaphragm strength and support for roofing systems without bonding to concrete. Its deep rib profile (38mm-76mm) enhances load distribution for dead loads (insulation, HVAC) and live loads (snow, maintenance). The deck acts as permanent formwork for lightweight concrete or directly supports single-ply membranes, featuring anti-ponding slopes (1/4:12 minimum) for water drainage. Key performance includes high wind uplift resistance (tested to ANSI/FM 4471), corrosion protection through G90 galvanization, and fast installation with mechanical fasteners. Used in low-slope commercial roofs, it provides cost-effective spanning (1.8m-4.5m between supports) while meeting building code requirements for structural integrity and fire ratings when paired with spray-applied fireproofing.

What's the difference between them?

Structural Function	Floor decks act as composite systems with concrete for load-bearing floors. Roof decks work as standalone structural platforms for roofing systems.
Material Composition	Floor decks use thinner gauge steel (0.8-1.5mm) with embossed patterns. Roof decks require thicker steel (20-22 gauge) for weather resistance.
Profile Design	Floor decks feature shallow trapezoidal ribs for concrete bonding. Roof decks have deeper ribs (38-76mm) for drainage and wind uplift resistance.
Performance Priorities	Floor decks focus on fire resistance and vibration control. Roof decks emphasize waterproofing and slope requirements (1/4:12 minimum).
Installation Requirements	Floor decks need shear studs for composite action. Roof decks require mechanical fasteners for wind uplift resistance.

roof deck

It is very important to understand the differences between metal floor decks and roof decks ensures you order the correct product for your construction needs. Floor decks provide composite strength for load-bearing floors, while roof decks offer weather-resistant protection. Always consider structural requirements, material specs, and performance needs before purchasing.

How Do Magnets Ensure Safety and Quality in Food Processing?

2025-09-19 - tags：Magnetic Liquid Filters With Quick Interface Connector Magnetic Separators Magnetic Strainer Filter Magnetic Trap Filter Thermal Insulation Magnetic Liquid Trap

In everyday food processing, we often overlook the unsung "safety guard" of magnets. They exist in various forms throughout the production line, silently safeguarding food safety and quality from the moment raw materials enter the factory to the moment finished product leaves the factory. How do these seemingly simple magnetic devices become such an essential and crucial part of the food processing process? Let's explore the important role of magnetic technology in the modern food industry.

Where does metal contamination in food come from?

- Impurities in raw materials: Metal fragments may be mixed into crops during the planting and harvesting process.

- Maintenance: Small parts such as screws and nuts that may be left behind during repairs and maintenance.

These contaminants range from bolts as large as 50 mm to wear debris as small as 30 µm, which can puncture packaging, cause cuts in consumers' mouths, or damage expensive subsequent equipment.

Magnetic Separation Technology: The Unsung Hero of the Food Industry

Magnetic separation technology utilizes high-intensity magnetic forces to effectively remove iron and other magnetic metal contaminants from food raw materials and production processes. Common magnetic separation equipment includes:

- Magnetic bars: Installed in feed ports and conveyor pipes to capture iron filings

- Magnetic screens: Used to filter metallic impurities from liquids and slurries

- Drawer magnetic separators: Remove fine metal contaminants from free-flowing dry products

- Magnetic separators: Used to screen and remove iron from recycled powders

Applications of Magnetic Technology in Various Food Industries

1. Grain Processing

In the processing of grains such as rice, flour, and cornmeal, strong magnetic bars are installed at the inlets of raw material cleaning equipment, mills, and packaging machines to effectively remove iron impurities from the raw materials.

This not only preserves the color and taste of the product but also extends the life of the equipment. For example, after installing strong magnetic bars in their production line, a large rice processing company reduced the amount of foreign matter in their product by 98%.

2. Edible Oil Production

In edible oil production, strong magnetic bars play a role throughout the entire process, from oil pressing to refining:

- During the pressing process, they prevent iron impurities from entering the oil pressing equipment.

- During the refining process, they further absorb iron impurities from the crude oil.

3. Baking and Confectionery

In the baking and confectionery industry, magnetic separators are used to inspect all incoming dry ingredients (such as flour and sugar) and liquid feeds (such as flavors, spices, and oils).

For example, Colonial Cookies of Canada has installed Pneumag magnetic separators and multiple fluid filters in its production line to protect its cookie manufacturing process from metal contamination.

4. Food Additive Production

The purity of food additives directly impacts food quality and safety. Strong magnetic rods ensure the purity of additive raw materials and prevent iron impurities from affecting the performance of food additives.

Magnetic separator

Magnetic Separation Technology and Food Safety Management Systems

Magnetic separation technology is a key component of the HACCP (Hazard Analysis and Critical Control Point) system. HACCP is an internationally recognized analytical system for identifying potential risks and implementing preventive measures to eliminate or reduce hazards.

A robust HACCP system with high-quality metal separation and detection offers many advantages:

- Monitoring raw materials from suppliers

- Preventing metal contaminants from entering the production process

- Promptly detecting machine wear or failure

- Control points that reduce unplanned maintenance and downtime

Many retailers today audit their suppliers' safety management systems for compliance with international standards, such as EU Regulation 852/2005 and ISO 22000. An effective magnetic separation system can help companies meet these regulatory requirements.

Key Considerations for Selecting and Maintaining Magnetic Separation Equipment

1. Raw Material Characteristics: Particle size, moisture content, and fluidity of the raw material will influence equipment selection.

2. Production Process: Continuous vs. batch production, and the degree of automation required.

3. Contamination Risk: The type and magnitude of potential metal contamination.

4. Cleaning Requirements: The ease of cleaning and sanitation of the equipment.

Regular inspection and maintenance of magnetic equipment is also crucial. This includes regular cleaning to remove adsorbed metal impurities, checking for weakening of the magnetic force, and ensuring proper installation.

Strong magnetic rods "quality defender" of new energy vehicle motors

2025-09-19 - tags：Magnetic Bar Magnetic Filter Bar Magnetic Filter Rod Magnetic Tube Magnetic Tube 14000 Gauss- Mirror Finish Magnetic rod

In today's rapidly developing new energy vehicle industry, the performance and reliability of the electric motor, as its core drive component, directly determine the vehicle's power output, range, and safety performance. However, the motor manufacturing process is complex, involving numerous metal processing and assembly steps. With even the slightest carelessness, tiny magnetic impurities such as iron filings and rust can enter key components, becoming "invisible killers" during motor operation. Against this backdrop, strong magnetic rods are quietly playing the role of "quality gatekeepers" in motor manufacturing, and their critical role cannot be ignored.

Strong magnetic rods are capable of performing critical tasks thanks to their superior technical features:

1. High-Intensity Magnetic Field: Made from rare earth permanent magnets (such as NdFeB), they deliver magnetic field strengths exceeding 8,000 gauss, effectively attracting micron-sized ferromagnetic impurities.

2. Temperature Stability: Utilizing high-performance magnetic materials with high intrinsic coercivity and high operating temperature, they maintain stable magnetic properties across a wide range of motor manufacturing environments.

3. Structural Diversity: Magnetic rods can be designed in various sizes, shapes, and magnetic strengths to meet diverse application scenarios and installation requirements, meeting the diverse requirements of motor manufacturing.

Strong magnetic rods, with their powerful iron removal capabilities, are used throughout the entire process of new energy vehicle motor manufacturing, from core processing to winding production to final assembly, silently protecting the quality and performance of the motor.

1. Motor Core Production: The "Nemesis" of Iron Filings

The production of motor cores is inseparable from silicon steel sheets. During the punching, shearing, and lamination processes, the mechanical forces of the equipment cause wear on the cutting tools and dies, leading to the generation of iron filings.

These seemingly insignificant iron filings can be extremely harmful if they enter the motor core. During motor operation, the iron filings within the core generate additional eddy current losses under the influence of the alternating magnetic field, causing severe heating of the core. This not only reduces motor efficiency but, over time, can damage the core and shorten the motor's lifespan.

High-strength magnetic rods are installed at the discharge port of silicon steel sheet processing equipment. Their powerful magnetic field acts like a keen "iron filing hunter," rapidly attracting iron filings. Made of rare earth permanent magnets with a high magnetic energy product, they can achieve magnetic field strengths exceeding 8,000 gauss, easily capturing even micron-sized iron filings.

2. Winding Production: The "Guardian" of Insulation

Enameled wire is the "blood vessels" of the motor windings, and the integrity of its insulation directly determines the safe operation of the motor. Iron impurities from worn winding dies or the raw materials themselves can enter the windings along with the enameled wire. Under the long-term effects of current heating and electromagnetic forces, iron impurities can easily pierce the insulation, causing short circuits between turns and leading to motor failure.

Inserting strong magnetic rods into the enameled wire delivery pipeline intercepts iron impurities at the source, ensuring the purity of the windings. Data shows that the use of strong magnetic rods increases motor power generation efficiency by approximately 8%, contributing to additional vehicle range. Higher power generation efficiency means that vehicles can travel farther with the same amount of power, precisely meeting consumers' demand for longer driving range.

3. Motor Assembly: The "Gatekeeper" of Purity

Strong magnetic rods also play an indispensable role in the motor assembly process. The motor casing, end caps, and internal connectors can also carry impurities such as iron filings during processing and handling.

Strong magnetic rods can be installed at key locations on assembly equipment to remove iron from components entering the assembly area, ensuring a clean environment within the motor and preventing various failures caused by iron impurities.

Finally, why do new energy vehicle motors require strong magnetic rods in particular?

New energy vehicle drive motors primarily include permanent magnet synchronous motors and induction asynchronous motors, with permanent magnet synchronous motors accounting for 94% of the domestic market.

These motors typically utilize neodymium iron boron permanent magnets, offering advantages such as high power density, high operating efficiency, high torque, and smooth operation. However, they also place higher demands on cleanliness:

1. Efficiency Requirements: New energy vehicle motors must maintain high efficiency across a wide speed range. Any excess loss caused by iron impurities will impact range.

2. Compact Design: Motors are trending towards higher speeds and smaller sizes, resulting in more sophisticated internal structures and increased sensitivity to impurities.

3. Reliability Requirements: As a core component of the vehicle, the reliability of the motor is directly related to its safety and service life.
