Specification

Sandwich Panel

Sandwich panels for steel structure roofs are prefabricated composite systems designed to balance thermal efficiency, structural integrity, and installation speed. Comprising two outer metal skins (galvanized steel or aluminum) bonded to an insulating core, they form a lightweight yet robust roofing solution. Here's a detailed breakdown:

1. Outer Skins:  Top sheets: Painted with PVDF, SMP, PE or HDP coatings with Rib or Corrugated type. Bottom sheets: Smooth-finished flat for interior aesthetics.

2. Core Materials:  Polyurethane (PUR/PIR): High thermal insulation (λ ≤ 0.022 W/mK), ideal for energy-efficient roofs. Rockwool: Non-combustible, fire-rated (up to 120 minutes), and sound-absorbing. EPS/XPS: Cost-effective insulation for low-load applications.

3. Thermal Performance:  U-values as low as 0.2 W/m²K reduce heat loss/gain, meeting strict energy codes.

4. Structural Efficiency: Span capacities up to 6 meters (with proper purlin spacing) minimize steel framework needs.

5. Installation Speed: Pre-cut panels with factory-applied seals reduce on-site labor by 40%, ideal for large-scale projects.

6. Fire Safety: Rockwool cores achieve Class A fire ratings, while PUR/PIR options offer flame-retardant formulations.

7. Recyclable steel/aluminum skins reduce environmental impact. Energy-efficient cores lower carbon emissions from heating/cooling.

Sandwich roof panels redefine modern steel construction by merging high-performance insulation, rapid assembly, and long-term durability—essential for projects demanding both functionality and sustainability.

Product Display

The above-mentioned PU/PIR/Polyurethane Sandwich Panels are high-performance core materials tailored for the wall and roof systems of steel structure buildings. As a key component in modern steel structure construction, these panels integrate multiple advantages to deliver comprehensive solutions for building envelopes.
In terms of material performance, they excel in thermal insulation. The closed-cell structure of PU/PIR/Polyurethane effectively blocks heat transfer, significantly reducing the building's energy consumption for heating and cooling and aligning with current low-carbon and energy-saving construction standards.

From the perspective of practical application, they offer strong structural stability. The panels feature good load-bearing capacity and can withstand external impacts, temperature changes, and humidity fluctuations, ensuring long-term durability of the building's wall and roof.

Additionally, they boast high construction efficiency. With standardized dimensions and lightweight properties, they simplify on-site installation processes, shorten the construction period, and lower overall project costs. Whether for industrial workshops, logistics warehouses, or commercial steel structure buildings, these sandwich panels provide a reliable, efficient, and energy-saving solution for wall and roof systems.
