High Quality Prefabricated Sandwich Wall Panels For Garage Warehouse Cold Room And Hotel For Exterior Building Walls
Polyurethane composite board has good insulation, heat insulation, and sound insulation effects, and polyurethane does not support combustion, which is in line with fire safety.
The combination of upper and lower panels with polyurethane has high strength and rigidity. The lower panel is smooth and flat, with clear lines, increasing indoor aesthetics and flatness. Easy installation, short construction period, and beautiful appearance make it an outstanding choice for modern architecture.
Lightweight & Aesthetically Pleasing: The weight is usually 10kg/m² - 14kg/m², equivalent to 1/30 of a red brick wall. The surface color is bright and does not require surface decoration.
Excellent Performance: Superior insulation, heat retention, and sound insulation capabilities. In terms of anti-caking performance, a 35mm thick polyurethane board is equivalent to a 1130mm red brick wall.
Fire Resistance Features
Combustion performance is Class B, and the maximum service temperature is 180 ℃ (250 ℃ allowed). Under the direct action of fire, there is carbon deposition, no fallout, no curl, and no melting phenomenon. After the flame burns, a layer of "graphite foam" develops on the surface, effectively protecting the foam structure in the layer.

Frequently Asked Questions
1. Who are we?
We are a professional manufacturer and exporter of building steel materials. Our products are exported to North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, Middle East, East Asia, Central America, and South Asia.
2. How do we guarantee the product quality?
Quality is guaranteed through strict manufacturing workflows: we always arrange pre-production samples prior to mass production, and a final inspection is always conducted before shipment.
3. What is our main business scope?
Our core business ranges across steel structure manufacturing, container houses, building plates, new materials for building steel products, photovoltaic energy, prefabricated buildings, packaging materials, and coated steel plates.
4. Why should you buy from us instead of other suppliers?
All products are shipped directly from the factory, bypassing third-party traders or middlemen. This ensures transparent pricing and products that are strictly quality-tested.
6. What are the key fire safety features of the polyurethane composite boards?
The boards have a combustion performance rating of Class B. Under fire, they carbonize instead of melting, curling, or creating fallouts. A protective graphite foam layer forms on the surface to shield the inner foam structure, sustaining temperatures up to 180 ℃ (temporarily up to 250 ℃).
