Q235B Q355B Light Steel Frame Construction Galvanizd Purlin Steel Structure
Pre-engineered steel structure buildings redefine modern construction methods. Unlike traditional block and concrete industrial buildings, these structures offer faster construction, better quality control, and easier installation.
Fabricated in strictly controlled factories, pre-engineered steel structures provide numerous advantages over traditional construction methods, including lower transportation and installation costs.
These buildings excel in industrial and commercial projects such as warehouses, workshops, plants, storage facilities, 4S exhibition rooms, office buildings, shopping malls, and school buildings. They offer significant cost savings, shorter completion times, and exceptional durability, making them the preferred construction solution.
- Primary Framing Elements: Columns and beams made from H-section steels (hot rolled or welded), easily bolted together on-site with factory primer, facing paintings, or galvanization for anti-rust protection.
- Secondary Framing Elements: Purlin and tie bar formed as secondary framing, fixed to columns and beams with common bolts.
- Bracing: Round steel with knee bracing and supporting parts to enhance stability and durability of the structure.
- Cladding: Roof and wall covered by color-coated corrugated steel sheet or steel sandwich panel, hot-dipped with zinc and aluminum compound for weather protection and aesthetic appeal.
- Windows and Doors: Plastic steel windows, aluminum-alloy windows, sliding doors, folding doors.
- Other Options: Gutter, downpipe, transparent sheet, ventilator, and bridge crane available per client requirements.
