Prefabricated office buildingare combined by steel structure frame, roof and wall steel cladding, aluminium windows & doors, etc. Steel structure frame refers steel columns, beams, tie bars, bracing, C/Z purlin, etc.
Design and drawing are done by our professional engineers.Customer just need to tell us the details and requirements,then we will issue a safe the economic solution by our expertise and experience.
Steel structure exhibition hall has the following advantages:
1. More saving on cost;
Steel structure is lighter than traditional buildings material, which helps to reduce foundation size and material;
2. Shorter for installation time;
Erection of steel structure building will be quicker as most of the steel members will be cutting and manufacturing the accurate size according to the drawing in factory and steel members are bolted together.
3. Good wind and earthquake resistance.
Steel structure can be designed to resist stronger wind and earthquake.
Steel structure
Primary frame element such as steel columns, steel beams and other members are made by hot-galvanized hot-rolled H section steels and welded section steel, which will be bolted together at site. A factory galvanization surface treatment is applied to get better anti-rusting and anticorrosion effect of primary framing elements.
Secondary Framing- Galvanized purlin, tie bar, roof and wall support, are formed as secondary framing.
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 building.
Cladding
Roof and Wall are covering of color-coated corrugated steel sheet, hot dipped with zinc and aluminum compound, which is fixed to the outside of structural building to protect it against bad weather or to have a good appearance.
