Modular Connecting Corridor Skywalk Prefab Steel Structures Fabrication for Urban High Rise Buildings
Prefab Steel Structures Materials advantage
1) Steel galvanized layer thickness: general area of the structure of the galvanized layer thickness of two sides is 180g/m2 (American Standard G60, single-side galvanized layer thickness of 13μM), strong corrosion area of not less than 270g/m2 (American Standard G90, single-side galvanized layer thickness of 20μM )
2) Durability: steel structure residential housing can prolong life, structure life up to 100 years
3) Earthquake resistance: application to the seismic intensity of 9 degrees above the region
4) Designing usage steel weight: 25-35kg/m2 (construction area)
5) Floor load: 250kg/square

Foundation system
Prefabricated villa keel structure with strip foundation, because the building lightweight, force bearing layer requirements is not high, endurance of every square meter 8-13 tons can meet the requirements, the foundation is usually 600 to 800 feet wide, base width is 180-200mm, 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, follow the endurance requirements for backfilling, based on the depth should be over winter frozen layer thickness.
Floor system
Floor system of prefabricated villa is composed of cold-formed steel frame, beam, floor OSB structure board, supports, and connecting parts, materials used are oriented strand board, fiber cement board, and plywood, light floors can load 316-365 kg per square meter.
Wall system
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, prefabricated villa use inner transverse wall as bearing wall, wall column is C shaped light steel, 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.
Flat roof system
Prefabricated villa keel structure of flat roof has two forms, one is no parapet wall but with bar and another is with parapet wall.
We are hornoed, from material purchase and tracing, shop drawing detailing, production arrangement, quality inspection, to on-going painting, packing and delivering, to have separated department to strictly control process, quality and traceability, so that the perfect structural steel bridge can be made.
Meanwhile various standards ranging from Europe EU Standard, America ASTM Standard, British BS Standard, Australia AS/NZS Standard structural steelworks fabrication are also available.
Warmly welcome all friends and clients from International market to visit us and have face talking together!
