Light Steel Structure Villa

1. Materials advantage—light steel keel

1.Steel galvanized layer thickness:The general area of the structure of the galvanized layer thickness of two sides is 180g/m²( American Standard G60, a single-side galvanized layer thickness of 13μ m ). The strong corrosion area of not less than 270 g/m²( American Standard G90, a single-side galvanized layer thickness of 20μ m ).

2.Designing usage steel weight is 25-35KG/m²(construction area)

3.The load of the floor: 250KG/ square

4.Durability: steel structure residential housing can prolong life, structure life up to 100 years

5.Earthquake resistance : application to the seismic intensity of 9 degrees above the region

2. The system of foundation

Light steel keel structure with strip foundation, because the building light weight, the force bearing layer requirements is not high, the endurance of every square meter 8 - 13 tons can meet the requirements, the foundation is usually 600 to 800 feet wide, base width is 180 - 200 mm. Depth as the geological conditions and the winter of frozen soil layer depends on the thickness, depth to dig to no disturbance of soil, if backfill, please follow the endurance requirements for backfilling. Based on the depth should be over winter frozen layer thickness.

3. The system of floor

Floor system of light steel structure housing is composed of cold-formed steel frame, beam, floor OSB structure board, supports, and connecting parts. The materials used are oriented strand board, fiber cement board, and plywood. The light floors can load 316-365 kg per square meter.

4. The Wall sysetem

Wall body of light steel structure is mainly composed of wall frame top beam, wall, wall bottom beam, wall support, wall panels and connecting components. Light steel structure housing use inner transverse wall as bearing wall, wall column is C shaped light steel, the wall thickness depend on the load, usually 0.84-2 mm, It is 400-600 mm between wall column spacing, Light steel structure housing the wall structure arrangement, can effectively bear and transfer vertical loads, and the arrangement is convenient. But the light steel structure house wall structure cannot bear horizontal loads.

5. The system of flat roof

Light steel keel structure of flat roof has two forms. One is no parapet wall but with bar and another is with parapet wall.
