Custom-Designed Steel Buildings for Industrial, Commercial & Agricultural Applications

We supply customized prefabricated steel warehouses designed for efficient storage and industrial operations.

From small storage sheds to large-scale distribution facilities, our steel buildings are manufactured to meet your project dimensions and functional requirements. Our services include structural engineering, steel fabrication, surface treatment, component inspection and export packing to support smooth installation on site.

Key Features of Our Steel Structures
1. Custom Structural Design

Each steel building is designed around the specific needs of your project, ensuring the structural layout suits your site conditions and intended use.

Our engineers can consider:

  • Building length, width, height and span
  • Local wind, snow and seismic conditions
  • Intended building function and occupancy
  • Door, window and access opening locations
  • Overhead crane and equipment loads
  • Applicable local building codes and 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 South Africa & Africa


2. Quick On-Site Installation with Bolted Connections

The main steel frame is connected using bolts, helping reduce on-site fabrication and streamline the installation process.

Typical installation equipment includes:

  • Suitable lifting equipment
  • Hand tools and power tools
  • Torque wrench
  • Installation and connection drawings
3. Factory Quality Control

Quality control is an important part of our steel fabrication process. Before shipment, we inspect the fabricated members and connection details to identify potential issues before they reach your site.

We verify:

  • Structural member dimensions
  • Bolt-hole positions and connection alignment
  • Base plate size and hole spacing
  • Brace geometry and assembly fit
  • Welding appearance and surface treatment
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.
