PU Sandwich Roofing Sheet
Thermal insulation: The thermal conductivity of polyurethane board is extremely low, and the thermal insulation effect is significant, which can effectively reduce heat loss and reduce energy consumption.
Lightweight and high strength: Polyurethane board has low density and light weight, but high compressive and bending strength, which is convenient for transportation and installation, and can withstand a certain load.
Environmental performance: Polyurethane board does not produce harmful substances during production and use, meets environmental protection requirements, and can be recycled.
Economical: The long-term energy-saving effect of polyurethane board is significant, which can greatly reduce operating costs and has a high cost performance.
Corrosion resistance: Polyurethane board has good chemical corrosion resistance, is suitable for various harsh environments, and has a long service life.
Product Introduction
PU Roof Sandwich Panel is a top - tier building material with a unique three - layer structure of a rigid polyurethane foam core between two metal facings. It's energy - efficient, offering excellent thermal insulation, which cuts heating and cooling costs. Its lightweight design eases installation and reduces structural load. With superior fire resistance and soundproofing, it ensures safety and comfort. Highly durable and weather - resistant, it requires little maintenance. Ideal for industrial, commercial, and residential roofing, it also suits various architectural designs, combining functionality and aesthetics.

Flow Chart of Polyurethane
The production begins with material prep, unwinding, and film application, then pressing. Next are spraying, preheating, and foaming for the polyurethane structure. After precise guidance, cutting, and cooling, the product is unloaded, packaged, and distributed, finishing the cycle.
Our Factory
The various production lines within the factory work closely together, the distance between parts and components from one workshop to another is short, and the material flow is fast, which reduces the logistics cost of the production process and avoids additional costs caused by multiple loading and unloading.
