Product Description
What is prefabricated steel structure building?
Compared with traditional building like concrete building, prefabricated steel structure building is a new quick installed building structure. The structure mainly comprises steel columns, beams, trusses, bracing, purlins, U channel, angle steel and steel plates, etc... They are connected together to be frame by welding, bolts and rivets.
Steel frame is typically consisting of vertical columns and horizontal beams which are bolted or welded together. Steel columns are vertical structural members that transfer compressive loads. It can be used to form the skeleton of a building. Steel beams are horizontal structural members that resist loads applied laterally to their axis. Structural steel framing is typically designed, fabricated and erected in accordance with applicable standards to ensure its safety.
All steel structure buildings’ components are detailed and manufactured in the factory. To cut, drill and weld strictly following the manufacturing drawings to ensure that the structure tolerance is less than 2mm.
Product Parameter
The main components of steel structure prefabricated building
● Primary Framing Elements
Columns, beams members are made by H section steels( hot rolled section steel/ welded section steel), which will be easily bolted together at site. A factory primer and facing paintings or galvanization surface treatment are applied to get better anti-rusting effect of primary framing elements.
● Secondary Framing Elements
Purlin, tie bar are formed as secondary framing, which will fix on columns and beams by common bolts.
● Bracing
Round steel is supplied with knee bracing and other supporting parts that need portal framing, which will improve the stability and durability of the whole structural hangar.
● Cladding
Roof and Wall are covered by color-coated corrugated steel sheet or steel sandwich panel, hot dipped with zinc and aluminum compound, that is fixed to the outside of structural building to protect it against bad weather or to make it look more attractive and last for generations.
● Windows and Doors
Plastic Steel Window/Aluminum-alloy Window; Sliding Door/Folding Door.
● Other Options:
Gutter, Downpipe, Transparent sheet, Ventilator and Bridge Crane will be fitted according to client’s requirements.
