Container Loading Tips for Exporting Sandwich Panels Safely
- tags：

For successful international shipping, to use the correct loading method is very important, because sandwich panels need to be carefully packaged, loaded and transported--Once the loading procedure goes wrong, it may cause product damage and financial losses.

 

First of all, to make sure that the container condition meets transportation standards is the first step. Propanel will conduct a thorough inspection of the container before loading operations begin. If the container floor has protruding nails or sharp objects - the panel surfaces will get scratched easily - this can cause quality problem, finally leading to customer dissatisfaction.

 

Loading of the sandwich panels

Secondly, packaging and weight distribution calculations must be done before actual loading. It is recommended to use pallets to protect the bottom layer. Never load above the recommended height - otherwise damage may occur - ultimately resulting in the product being damaged and unable to be installed correctly.

 

Thirdly, security measures should be strictly done before loading. Key points such as angle brackets, protective plates, tension adjustment of straps, and filling of gaps between stacks require experienced workers to handle them according to standard operating procedures. Appropriate inflatable bags or air cushions should fill the empty space and prevent unnecessary movement of the container in rough sea conditions.

 
How Do Insulated Panels Prevent Energy Loss in Cold Storage?
- tags：

For a good cold room, using the right insulation system is very important—cause the entire refrigeration efficiency depends on how well the structure keeps cold air inside. Energy loss not only increases electricity consumption but also affects product freshness and storage stability. Insulated sandwich panels are the key solution to keep consistent temperature and reduce energy waste effectively.

 

The PU sandwich panel is the most common and efficient insulation material used in modern cold storage construction. It is made of two layers of pre-painted steel sheet with a polyurethane (PU) insulated core in between. PU foam has one of the lowest thermal conductivity levels among building materials, meaning it minimizes heat transfer between the inside and outside of the room. Propanel (propaneltech.com) focuses on manufacturing high-performance PU cold room panels, providing customers with stable insulation, long lifespan, and fire-resistant performance at the same time.

 

Before selecting insulated panels, it is important to match the panel thickness with the target temperature of the cold room. The following table shows the general recommendation:

Panel Thickness (mm)

Storage Temperature (°C)

Typical Application

75 mm

+10°C to +5°C

Food processing, air-conditioned room

100 mm

+5°C to -5°C

Chiller room, fruit and vegetable storage

150 mm

-5°C to -20°C

Frozen meat, dairy storage

200 mm

-20°C to -40°C

Deep freezer, ice cream cold room

 

Proper installation and sealing of the PU sandwich panels are equally important. Gaps, uneven joints, or unsealed corners may cause cold air leakage—resulting in continuous energy loss and compressor overload. That’s why Propanel emphasizes professional installation guidance and precise joint systems to ensure the panels fit tightly, keeping the cold room fully sealed.

 

How Sandwich Panels Improve Energy Efficiency in Buildings?
- tags：

For modern construction projects, to use the right building materials is very important, cause buildings require excellent thermal performance--Once the insulation cannot be guaranteed, it may greatly increase energy consumption and operational costs. The sandwich panel—it is usually composed with two metal sheets with insulated core material in between. As is known to all, the sandwich panel is the perfect building material for thermal insulation—so it gives the best insulation performance with structural strength at the same time.

 

Different middle materials of sandwich panel

First of all, There are 3 core material of sandwich panel: EPS, rock wool, and PU—each have unique advantages for specific applications. EPS panels provide cost-effective insulation for warehouses and cold storage. Rock wool panels offer superior fire resistance for industrial plants and commercial buildings. PU panels gives the highest thermal efficiency for temperature-sensitive environments. Propanel, just focus on supplying all types of sandwich panels, gives customers the best solution also professional advice at the same time.

 

Secondly, each core material provides different levels of insulation effectiveness and additional advantages:

 

Core Material

Thermal Conductivity

Key Advantages

Best Applications

EPS

0.032-0.038 W/m·K

Lightweight, Cost-effective

Warehouses, Distribution Centers

Rock Wool

0.035-0.042 W/m·K

Fire-resistant, Sound-absorbing

Industrial Plants, Public Buildings

PU

0.022-0.024 W/m·K

High efficiency, Best thermal insulation

Cold Storage, Pharmaceutical Facilities

The low thermal conductivity values—especially PU's exceptional performance—directly translate to reduced heating and cooling costs, preventing energy loss through walls and roofs.

 

Thirdly, good installation also ensures insulation - if panels are installed incorrectly - gaps can form - which can lead to the development of cold bridges. Professional installation according to Propanel specifications is important to achieve the advertised R-value and energy savings.

Black annealed steel wire and galvanized steel bar binding wire a complete material comparison analysis
- tags：

In the construction industry, rebar tying is a crucial step in ensuring structural stability, and the choice of tying wire directly affects construction quality and subsequent maintenance costs. Black annealed wire and galvanized wire are two common tying materials, each with its own characteristics and suitable for different scenarios. Below, we will compare these two materials in detail.

 

 

Feature Dimension Black Annealed Wire Black Annealed Wire Galvanized wire Galvanized wire
Process and Appearance Low-carbon steel wire is annealed (heated and then slowly cooled), resulting in a black color. The surface may be coated with anti-rust oil. The surface of low-carbon steel wire is hot-dip or electro-galvanized, giving it a silvery-white color.
Core Advantages It has excellent flexibility, is easy to bend and wrap, and requires little effort to operate. It has strong corrosion resistance, and the zinc coating provides long-lasting protection and a long service life.
Main Limitations It has poor corrosion resistance and is prone to rust when exposed to humid environments. It has high hardness and poor flexibility, making it relatively difficult to handle manually.
Cost Relatively economical. The cost is usually higher due to the galvanizing process.
Typical Application Scenarios Rebar tying, handicraft making, and material bundling in indoor or dry environments. Outdoor, damp environments: building tying, fencing, and barbed wire.

 

How to Choose?

The choice of binding wire depends primarily on your project requirements and work environment:

Prioritize Black Annealed Wire: If your project is indoors or in a dry environment, and you require high efficiency and ease of handling, black annealed wire is the ideal choice. Its flexibility makes binding faster and more economical.

Prioritize Galvanized Wire:If your project is in a humid or corrosive environment such as outdoors, in a basement, or near the sea, galvanized wire is essential. Although the initial investment is slightly higher, its superior rust resistance ensures long-term stability and avoids safety hazards and maintenance costs caused by corrosion.

 

In summary, both black annealed steel wire and galvanized steel bar binding wire have their advantages and disadvantages. In practical applications, construction personnel should comprehensively consider factors such as cost, corrosion resistance, and ease of construction based on the specific circumstances of the project to rationally select binding wire materials in order to ensure construction quality and project safety.

 

Rebar binding wire How does a small material affect the overall safety of a building structure?
- tags：

On construction sites, rebar tying wire is often considered an inconspicuous auxiliary material, but its quality directly affects the structural integrity and safe lifespan of the entire building. Although it does not directly bear weight, it is crucial for ensuring the coordinated operation of reinforced concrete.

 

The core function of tying wire: "Positioner" and "Fixer" for rebars. Before pouring concrete, the rebar cage or mesh must be securely fixed with tying wire to ensure:

Precise design positioning: Each rebar functions correctly on the design coordinates, guaranteeing the effectiveness of structural calculations.

Shared load-bearing: The rebar mesh forms a unified whole, evenly distributing the load.

Pouring stability: Resisting the impact and vibration during concrete pouring, preventing rebar displacement.

 

Tie Wire Rebar Tie Wire for Rebar Tying MachineTie Wire Rebar Tie Wire for Rebar Tying Machine

 

The impact of rebar tying wire quality on structural integrity will be discussed in detail below.

First, the quality of the rebar tying wire directly affects the structure's load-bearing capacity. Using inferior rebar tying wire can lead to insecure binding, resulting in weak connections between rebars or even loosening. This directly reduces the overall load-bearing capacity of the structure, increasing the risk of building collapse. Therefore, selecting high-quality rebar tying wire during construction is crucial to ensure structural stability and safety.

Second, the quality of the rebar tying wire affects the structure's durability. During building use, rebar is exposed to the external environment. Using inferior tying wire makes it susceptible to oxidation and corrosion, reducing the rebar's lifespan. This directly impacts the durability of the entire building structure and may even lead to premature aging and damage.

Furthermore, the quality of the rebar tying wire also affects the construction quality and project progress. Using substandard tying wire can easily cause problems during construction, increasing construction difficulty and time costs. Choosing reliable rebar tying wire ensures smooth construction, improves project efficiency, and guarantees the quality of the structure.

 

How to Choose Qualified Binding Wire?

To ensure project quality, the following should be considered when selecting binding wire:

Material and Process: For humid environments, galvanized wire (especially hot-dip galvanized) is preferred, as its rust resistance is far superior to ordinary black iron wire.

Specification Matching: The diameter must match the rebar specification (commonly 20-22 gauge) to ensure sufficient strength.

Product Standards: Select qualified products that meet national or industry standards.

Are Thicker Acoustic Panels Better?
- tags：

One of the most frequently asked questions by buyers when choosing acoustic panels is:

 

Are thicker acoustic panels better?

Custom Solutions Acoustic Wood Slat Panels

In short, the answer is yes—but not always in the way people expect.

 

Panel thickness does affect sound absorption, but it's only one part of the overall acoustic performance. In this article, we'll explain how thickness works, when thicker panels are more beneficial, and how to choose the right solution for your space.

 

How Acoustic Panels Absorb Sound

 

Acoustic panels reduce echoes and reverberation in a room by absorbing sound energy, especially mid-to-high frequency sound waves.

 

Key factors affecting performance include:

 

Panel thickness

 

Material density

 

Surface design

 

Installation method

 

Air gap behind the panel

 

Thickness alone does not guarantee better results.

 

Does thickness really improve sound absorption?

 

Yes—especially for low frequencies.

 

Generally speaking:

 

Thicker panels can absorb a wider frequency range.

 

They are more effective at low frequencies than thinner panels.

 

For example:

 

12-25 mm thick panels primarily absorb high frequencies.

 

40-50 mm thick panels absorb mid-frequency frequencies more effectively.

 

Thick panels with backing systems help control low-frequency energy.

 

However, for everyday residential and commercial spaces, ultra-thick panels are often unnecessary.

 

Thicker with Smarter Design

 

Modern acoustic solutions are not simply about increasing thickness, but about balancing design.

 

For example, wood slat acoustic panels use:

 

Rigid medium-density fiberboard slats for sound diffusion

 

High-density polyethylene terephthalate (PET) felt for sound absorption

 

Thickness optimized for the actual space

 

This combination achieves effective acoustic control without adding excessive volume or visual clutter.

 

When to Need Thicker Acoustic Panels

 

Thicker acoustic panels are best suited for:

 

Recording studios
