Project Overview
This heavy industrial steel workshop is designed for rail traffic equipment production. Our comprehensive service includes design proposal and drawings, fabrication of steel structure components, and complete installation including steel structure, overhead crane, and roof/wall insulation panels.
Design Advantages
- High strength & large span: Lattice steel columns bear heavy crane loads and wind pressure while optimizing steel usage
- Rapid construction: Prefabricated components enable fast assembly (40 days for 6,000m² buildings)
- Aesthetic flexibility: Modern lines with multiple color options and material choices for walls
- Cost efficiency: Lightweight structure reduces foundation costs with faster ROI than concrete buildings
