2 Product Features

Details of Sandwich Roof Panel

Thermal insulation: Low thermal conductivity, about 0.038-0.043W/ (m · K), effectively reducing heat transfer and keeping indoor temperature stable.

High cost performance: Low raw material cost, low transportation cost and installation cost.

Light weight: About 10kg/㎡, much lower than traditional roofing materials, reduce the overall

weight of the building, reduce the cost of foundation and structure.

Easy installation: Using plug-in or splicing installation methods, fast construction speed, greatly shorten the construction period. Cut at will, easy to install and adjust on site.

High strength: With high-strength steel plate as the panel, and EPS core composite, has good bending and compressive performance, withstand a certain roof load.

Beautiful and durable: rich colors, clear lines, to meet the design needs of different buildings. 10-15 years do not fade, if every ten years to spray anti-corrosion paint, plate life can reach more than 35 years.

Sound insulation performance: Good sound insulation, can reduce external noise, provide a relatively quiet indoor environment.

Environmental performance: EPS materials can be recycled, and no harmful substances are released during use.
