What is a Steel Structure Factory?
A steel structure factory (also called a pre-engineered steel building/PEB factory) is a modern industrial building where structural steel serves as the primary load-bearing framework, instead of traditional reinforced concrete. Its components are mostly prefabricated in a dedicated fabrication plant with high precision, then transported to the site for fast bolted/welded assembly.
Core Components
- Main Frame: Steel columns, main beams/rafters (often H-sections), forming the core skeleton to bear all vertical and lateral loads
- Secondary Frame: Purlins (C/Z-shaped steel), bracings, tie rods—boosting rigidity and wind/seismic resistance
- Envelope System: Insulated sandwich panels, corrugated steel sheets for roofs and walls, providing weatherproofing, thermal insulation, and noise reduction
- Accessories: Crane beams, doors, windows, ventilation systems, fireproof coatings, anti-corrosion treatments (e.g., galvanizing)
