PUR Panel

A PUR Panel is a high-performance variant of double-layer color steel sandwich panels. Constructed with polyurethane (PU) as the core material and color coated steel sheets as face sheets, it's manufactured through composite pressing-boasting ultra-high thermal insulation efficiency as its standout advantage. Designed for modern construction needs, this panel combines advanced material technology with practical functionality, making it a top choice for projects prioritizing energy efficiency, durability, and ease of installation.

The panel's core structure consists of three key components: color coated steel face sheets, polyurethane (PU) core, and high-strength adhesive layer.

The PU core is produced via foaming technology, featuring an ultra-high closed-cell rate (typically over 90%). This unique structure not only gives it superior thermal insulation performance that far surpasses other core materials (such as rock wool or EPS) but also enhances its overall structural stability.

The top and bottom face sheets are high-quality color coated steel, available with coating options like PE, HDP, or PVDF to ensure excellent corrosion resistance, weather resistance, and long-lasting aesthetic appeal.

The adhesive layer uses industrial-grade high-strength, weather-resistant adhesive, which firmly bonds the face sheets to the PU core-preventing delamination even in harsh environmental conditions (e.g., extreme temperatures, humidity, or mechanical stress).

1. Industry-Leading Thermal Insulation

PU's inherent thermal insulation properties are unmatched: its insulation efficiency is more than twice that of rock wool (with a thermal conductivity as low as ≤0.024 W/(m·K)). This means the panel can significantly reduce heat transfer between indoor and outdoor spaces, cutting energy consumption for heating or cooling by 30-50% compared to traditional building materials. It's an ideal solution for energy-saving construction projects.

2. Excellent Sealing & Waterproofing

Thanks to the closed-cell structure of the PU core, the panel is completely non-absorbent. It effectively blocks moisture and water vapor penetration, preventing mold growth, rust on the steel substrate, or structural damage caused by dampness. This makes it perfectly suited for low-temperature environments (e.g., cold storage facilities) and regions with high humidity.

3. Lightweight Yet Durable

Despite its lightweight design (typically 10-15 kg/m²), the panel offers strong bending resistance and structural rigidity-resisting deformation even under external pressure. Its lightweight nature simplifies transportation and on-site handling, while the standardized dimensions allow for direct, fast installation without the need for complex cutting or additional processing. This can shorten the construction cycle by 20-40% compared to conventional building methods.

4. Safe & Eco-Friendly for Indoor Use

The PU core and all auxiliary materials are formaldehyde-free and low-VOC (volatile organic compounds), releasing no harmful gases or unpleasant odors. It meets international environmental and health standards, making it safe for indoor applications such as office partitions, clean rooms, and residential interiors.

Cold Storage & Low-Temperature Facilities: Perfect for cold storage warehouses, refrigerated logistics centers, pharmaceutical storage rooms, and food processing plants-where stable low temperatures and energy efficiency are critical.

Industrial Buildings: Ideal for workshops, factories, and production facilities with high thermal insulation requirements (e.g., electronics manufacturing plants, chemical processing facilities).

Commercial & Civil Construction: Suitable for shopping malls, office buildings, prefabricated houses, and modular constructions-offering fast installation, energy savings, and a clean, modern appearance.

Specialized Projects: Used in mobile clinics, temporary shelters, and data centers, where lightweight, insulation, and quick deployment are essential.
