Prefabricated Large-Span Workshop Warehouse With Gable Frame Structure Prefab Building
Custom-Designed Steel Buildings for Industrial, Commercial & Agricultural Applications
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.
Key Features of Our Steel Structures
1. Custom Structural Design
Every building is engineered according to the actual project requirements rather than using a fixed standard design.
Our engineers can consider:
- Building dimensions and layout
- Wind and snow loads
- Seismic requirements
- Building use and occupancy
- Door and window openings
- Crane or equipment loads
- Local design standards
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 |

2. Bolt-Together System — Faster & Easier Installation
Main structural connections are designed for efficient bolted installation, reducing the need for on-site welding and fabrication.
Typical installation equipment includes:
- Mobile crane or telehandler
- Standard hand tools
- Torque wrench
- Erection drawings
3. Factory Quality Control
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
4. Designed for Your Local Climate Conditions
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.
5. Long-Lasting Corrosion Protection
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.
Project Case Study | 360㎡ Hay Storage Steel Barn in Alberta, Canada
Project Overview
Location: Red Deer County, Alberta, Canada
Building Type:Hay Storage Barn
Building Area: 360㎡ (12m × 30m)
Eave Height: 5.0m
Ridge Height: 6.8m

| 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 |
Project Advantages:
- Designed for Alberta’s cold climate and strong wind conditions
- Improved ventilation to protect stored hay from moisture and mold
- Drive-through layout for efficient tractor loading and unloading
- Prefabricated components for faster installation
