Quotation Requirements

To design and quote the best possible steel structure workshop or warehouse for you, please provide the following details:

  • Project Location: Country and city.
  • Dimensions: Length × Width × Eave Height (mm).
  • Wind Load: Maximum wind speed (kN/m², km/h, or m/s).
  • Snow Load: Maximum snow depth (kN/m², mm) and temperature range.
  • Seismic Grade: Specific class or level required.
  • Brick Wall: Is a brick wall needed? If yes, height requirement (e.g., 1.2m, 1.5m).
  • Thermal Insulation: Options include EPS, Glass Fiber, Rock Wool, PU panels, or single skin steel sheets.
  • Doors & Windows: Specific quantities and dimension details.
  • Crane System: If needed, indicate lifting capacity (Tons) and maximum lifting height (m).

Frequently Asked Questions (FAQ)

Q1: What raw materials are used for your main steel frames?
We utilize Q235 and Q355 grade carbon structural steel (equivalent to A36, A572 Gr.50, S235JR, and S355JR standards) for fabricating H-section welded columns and beams to ensure optimal load-bearing strength.
Q2: What is the typical lifespan of these prefabricated structures?
Designed to withstand severe weather conditions, our high-grade steel structures have a standard structural service life exceeding 50 years under routine maintenance.
Q3: How do you verify product quality before delivery?
We employ a dedicated internal QA team to check dimensions and weld integrity. We also carry out strict structural pre-assembly inside our factory bays to ensure all parts fit together cleanly before packing.
Q4: Do you offer structural design and installation services?
Yes, we offer full design capabilities and provide detailed assembly blueprints. If requested, we can deploy engineers and installation supervisors overseas to assist with the structure setup.
Q5: How are the structural elements packaged and transported?
All components are placed onto steel pallets to avoid bending during transit, secured, and then directly loaded into 40HQ container systems for ocean shipping.
Q6: What insulation systems can you apply to the walls and roof?
We support several configurations depending on thermal requirements, including EPS, Glass Fiber, Rock Wool, and PU Sandwich Panels, or cost-efficient non-insulated corrugated steel sheets.
