PRIMARY FRAME
Primary framing is the main structure supporting and carrying the gravity or vertical loads of the building to the foundationand. The main frame members include columns, beams and other supporting members with shape and size that based on the application and requirements.
SECONDARY FRAME
Secondary framing provides the stabilizing members that prevent the main frame from twisting out of shape, secondary components can also contribute to the structural support and provide the means to attach wall, roof and interior elements, including purlin, tie rod, angle support, tie bar, sleeve pipe, roof bracing and column bracing. The secondary framing usually transfers loads to the main frame.
MÁI
- Hệ mái là kết cấu che chắn theo phương ngang, nhằm bảo vệ không gian và tất cả tài sản (gồm người và vật chất) bên trong công trình tránh khỏi tác động của thời tiết và môi trường. Ngoài ra, kết cấu này còn giúp cho ngôi nhà thêm phần thẩm mỹ. - Vật liệu thông dụng hệ mái: các tấm tôn cách nhiệt đa tầng với nhiều tính năng bảo vệ cho vật liệu nền và công trình.
VÁCH
- Hệ vách của một công trình là kết cấu bao che theo phương đứng, nhằm bảo vệ không gian và tất cả tài sản (gồm người và vật chất) bên trong công trình tránh khỏi tác động của thời tiết và môi trường. - Vật liệu thông dụng hệ vách: các tấm tường có nhiều sự lựa chọn khác nhau gồm có tôn lợp, tôn panel (tôn sandwich), tấm thép,...

ROOF
- The roofing system is a horizontal shielding structure, to protect the space and all assets (including people and materials) inside the building from the weather and environment impact. In addition, this system also helps make the structure more aesthetic.
- Common materials for roofing system: multi-layer insulated corrugated sheet metal with protection features for foundation materials and structures.
WALL
- The wall system of a building is a vertical covering structure, in order to protect the space and all assets (including people and materials) inside the building from the effects of weather and the environment.
- Common materials for the wall system: the wall sheet have many different choices including roofing corrugated sheet metal, corrugated sheet metal (sandwich corrugated iron), steel sheet,...
