低层别墅的屋面大都为坡屋面，因此屋面结构基本上采用的是由冷弯型彩钢钢构件做成的三角型屋架体系，轻钢构件在封完结构性板材及石膏板之后，形成了非常坚固的"板肋结构体系"，这种结构体系有着更强的抗震及抵抗水平荷载的能力，适用于抗震烈度为8度以上的地区。
The roofs of low-rise villas are mostly sloped roofs, so the roof structure basically adopts a triangular roof truss system made of cold-formed color steel members. After sealing structural plates and gypsum boards, the light steel members form a very solid "plate rib structure system". This structure system has a stronger ability of anti-seismic and horizontal load resistance, which is suitable for anti-seismic intensity of 8 degrees The upper region
