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.
We do not use a generic structural design for every project. Each building is engineered according to the project location, applicable standards and required structural loads.
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 |
Our steel frames are designed primarily for bolted site assembly, 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:
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.
The surface protection system is selected according to the project location and environmental conditions
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 solutions can be specified for coastal, industrial and other corrosive environments.
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.
