Large Span Heavy Steel Structure Fabrication Q235B Q355B Steel Fabricated Building

Heavy steel structure building for industrial and commercial projects are steel structures built over structural concepts of primary members, secondary members, roof and wall cladding connected to each other and kinds of other components. These buildings can be provided with different structural and non-structural additions such as skylights, wall lights, turbo vents, ridge ventilators, louvers, roof monitors, doors & windows, trusses, mezzanine floors, fascias, canopies, crane systems, insulation etc., based on the customer's requirements. All the steel buildings are custom designed to be lighter in weight and higher in strength. Thus steel building designs have become more flexible, durable and adaptable over the last decades of years which has made steel one of the preferred materials for building construction.

The heavy steel structure building mainly includes following parts:

Main steel frame is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plate, and adopts rust removal and anti-rust process such as shot blasting, painting and galvanizing. Welding, bolts or rivets are usually used to connect each member or component.

Secondary members connect the main frame and help in resisting part of the longitudinal loads that are applied on the building such as wind and earthquake loads.
Steel purlin is available in 1.8 mm, 2.0 mm, 2.2 mm, 2.5 mm and 3.0 mm thickness. The purlin come with a galvanized sheet.
Column bracing is a connecting member set between two adjacent columns to ensure the overall stability of the building structure, improve lateral stiffness and transfer longitudinal horizontal force.

Steel sheet, its base sheet is usually be galvanized sheet or aluminium zinc sheet with organic coating. It has the advantages of good corrosion resistance, bright color, beautiful appearance, convenient processing and forming, and has the original strength of the steel plate and low cost.
The thickness of steel sheet usually be 0.3mm-0.7mm and used in different building and requirement.
Sandwich panel is composite insulation panel made by two sides steel sheet and heat insulated core material through binder (or foam). The core can be EPS (polystyrene), fiberglass wool, rock glass wool and PU (polyurethane), thickness 50mm, 60mm, 75mm, 100mm, 150mm, 200mm, etc.
