Quick Erection H Steel Columns And Beams Prefabricated Steel Structure Factory
Prefabricated steel structure factories represent innovative building construction solutions. Their economical pricing, convenient transportation, and quick installation make them increasingly popular in the construction industry.
These structures typically consist of H steel columns, H steel beams, purlins, roof sheets, wall sheets, rolling doors, and windows. The main structural components (H columns & beams) are secured with high-strength bolts, while purlins are fixed to columns and beams using 4.8S bolts, enabling faster erection compared to traditional concrete construction systems. The roof and walls utilize lightweight steel sheets or sandwich panels, further reducing installation time.
Product Specification
Our raw materials are sourced from China's largest steel mills and must meet stringent quality requirements:
Steel selection principles ensure structural safety, reliability, and cost-effectiveness while preventing brittle failure. Considerations include structural importance, load characteristics, connection methods, working environment, and steel thickness.

Production Process
1. Cutting
Steel components are precisely cut to required dimensions using advanced techniques like automatic laser cutting machines.
2. Assembly
Steel pieces are fitted together according to engineering drawings and specifications.
3. Welding
Components are securely joined using various welding techniques to enhance load-bearing capacity.
4. Rust Removal
Surfaces are cleaned using sandblasting, shot blasting, or chemical cleaning to eliminate corrosion.
5. Surface Treatment
Customized spray painting or hot-dip galvanizing protects against corrosion.
