Definition and characteristics of steel structure
Steel structure refers to a building system primarily composed of steel materials, connected through welding, bolting, etc. It features high strength, lightweight, fast construction speed, and recyclability.
Types of steel
Common types of steel include carbon steel, alloy steel, and stainless steel. Carbon steel is the most widely used structural steel, while alloy steel enhances performance by adding other elements.
Connection mode of steel structure
The primary connection methods for steel structures are welding, bolting, and riveting. Welding is suitable for permanent connections, while bolting allows for disassembly and adjustment.
Advantages of steel structure
Steel structures offer advantages such as high load-bearing capacity, excellent seismic performance, short construction cycles, and environmental sustainability.
Application field of steel structure
Steel structures are widely used in high-rise buildings, bridges, industrial plants, sports stadiums, and other fields.
Fire prevention and corrosion prevention of steel structures
Fire protection and anti-corrosion measures are essential for steel structures. Fire protection includes applying fire-resistant coatings, while anti-corrosion measures involve painting with anti-rust paint or using galvanizing processes.
Construction process of steel structure
The construction process of steel structures includes design, material procurement, component fabrication, on-site installation, and quality inspection.
The future development trend of steel structure
With the rise of green buildings and intelligent construction, steel structures are evolving towards higher strength, lighter weight, and greater environmental friendliness.
Product Specification
Components of steel structure workshop
● 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 Sandwich Door/Electric rolling up shutter Door/lifting door
● Other Options:
Gutter, Downpipe, Transparent sheet, Ventilator and Bridge Crane will be fitted according to client’s requirements.
