Product Description
Our metal frame construction solutions include prefabricated steel structures for various applications such as warehouses, workshops, storage sheds, garages, hangars, and commercial buildings. We handle complete projects from design to installation.
Key Cost Factors
- Building height: Construction cost increases by 2-3% for every 10cm increase
- Crane requirements: Proper tonnage selection is crucial for cost efficiency
- Protection structures: Doors, windows, and exterior walls affect overall cost
- Design structure: Building purpose, location, and usage requirements
- Construction area: Larger areas require more steel, increasing costs
- Span length: Generally, larger spans result in lower costs per unit
- Steel quantity: The most significant cost factor, affected by design and material source
