Use metal (steel and aluminum alloy etc) as load-bearing structure, metal composite materials and aluminum sheet as surface material according to building shape and spatial use function below the roof, all kinds of roof to decorate the building.

Divided into the following categories by surface materials:
1.elevation side link type metal roofing system
2.Aluminum single panel metal roofing system
3.Composit metal roofing system

Property instructions:
1. roofing overall weight is light suitable for great span space;
2. anti-distortion ability. It has absorbing function on form changing resulted in temperature change and earthquake.
3.beautiful exterior effect of glass material roofing and low cost to maintain and clean.
4.set open window on the roofing may realize natural ventilation and smoke giving out.
5.high speed of construction may shorten the construction cycle.
6.main construction materials adopt recycle and environment protection materials.

Elevation occlude metal roofing
●Structure features--roofing panel uses aluminum magnesium alloy board, connected by elevation occlude joint. Roofing system main body is connected by floating joint, and fully absorbed main body movement.
●Waterproof system--uses double layer waterproof structure and draining water system.
●Noise reduction--perforation steel plate and the glass fiber sound absorption cotton may absorb noise--remarkable noise reduction feature.
●Thermal property--roofing system uses glass fiber thermal cotton to achieve excellent thermal property.
