Our prefabricated steel structure buildings are engineered, manufactured and supplied according to your project requirements.
Whether you need a steel warehouse, workshop, factory, agricultural building, machinery storage facility or large-span industrial building, we provide a complete solution from structural design and factory fabrication to quality inspection, export packing and delivery.
Every building is engineered according to the actual project requirements rather than using a fixed standard design.
Our engineers can consider:
Applicable Standards:
| Standard | Application Regions |
|---|---|
| EN 1090-2 EXC2/EXC3 | Europe, UK, Middle East |
| UKCA / CE Marking | UK & EU |
| NBCC + CSA S16 | Canada |
| AISC 360 / ASCE 7 | USA & Caribbean |
| AS/NZS 1170 | Australia, New Zealand & Pacific Islands |
| SANS 10160 / SANS 10162 | South Africa & Africa |
Main structural connections are designed for efficient bolted installation, reducing the need for on-site welding and fabrication.
Typical installation equipment includes:
Before loading containers, we conduct a full factory inspection to ensure smooth installation on site.
We verify:
✓ Column-to-rafter and rafter-to-rafter connection alignment
✓ Base plate accuracy and anchor bolt dimensions
✓ Brace lengths and connection angles
Every building is engineered based on actual environmental loads:
| Load Type | Design Capability |
|---|---|
| Snow Load | Up to 5.0 kPa |
| Wind Speed | Up to 250 km/h (70 m/s) |
| Seismic Design | Zone 0–4 |
| Temperature Range | -45°C to +50°C |
From cold regions to coastal areas and high-wind zones, our structures are designed for reliable long-term performance.
Steel durability starts with proper protection.
Standard Protection:
✓ Hot-dip galvanizing ≥85μm zinc coating
✓ Tested according to ISO 1461
For harsh environments, we offer:
✓ Heavy galvanizing ≥140μm
✓ Duplex coating system (Galvanizing + Epoxy Primer + Polyurethane
Topcoat)
✓ Stainless steel fasteners (A2-70 / A4-80)
✓ Weathering steel (Corten steel) upon request
Suitable for coastal areas, industrial environments, and projects requiring extended service life.
Location: Red Deer County, Alberta, Canada
Building Type:Hay Storage Barn
Building Area: 360㎡ (12m × 30m)
Eave Height: 5.0m
Ridge Height: 6.8m
Located in central Alberta, the client needed a reliable storage building for approximately 400 tons of hay bales during the winter season.
Due to Alberta’s dry climate, strong winds, and large temperature variations, the building required excellent ventilation while maintaining structural stability against strong Chinook winds.
A customized prefabricated steel building solution was designed according to local climate conditions and project requirements.
| Item | Specification |
|---|---|
| Structure | Heavy-duty portal frame steel structure with welded H-section columns and rafters |
| Design | 12m clear span design for tractor operation and efficient hay bale storage |
| Wall System | 0.4mm corrugated steel wall cladding with 0.6m continuous ventilation openings |
| Roof System | 0.5mm Aluzinc steel roof panels with anti-corrosion coating |
| Doors | 2 * Sliding Doors (5.0m × 5.5m) at both gable ends |
| Ventilation | Open gable design for natural airflow and moisture control |
| Foundation | Concrete pier foundation with raised steel column base plates |
The project timeline depends on the building size, design complexity, and destination.
Typical process:
Most standard steel building projects can be delivered within 10–14 weeks after order confirmation.
Yes.Our engineering team provides a complete structural solution, including:
The design can be customized according to your project requirements and local wind, snow, and seismic conditions.
Yes, we can provide installation support according to your requirements.
Options include:
Our bolted steel structure system is designed for efficient assembly with local labor.
Yes. Width, length, height, roof slope, frame spacing, doors, windows, insulation and other features can be customized.
A complete steel building package may include:
The package can be customized based on your project needs.
Quality control is carried out throughout the manufacturing process:
All components are checked before delivery to ensure smooth installation on site.
