High strength Building Steel Structure components engineered to support multi story buildings and complex architectural designs
What Is a Prefabricated Steel Structure Building?

A prefabricated steel structure building is a bolt-together steel frame system in which every column, rafter, purlin, and connection plate is precision-cut, drilled, and welded in our factory — then containerized and shipped to your site for rapid assembly.

Unlike traditional on-site steel fabrication (which is slow, weather-dependent, and expensive in most countries), our approach delivers:

  • 30–50% faster construction compared to conventional steel erection
  • Zero on-site welding — 100% bolted connections
  • Lower total project cost through factory efficiency and reduced site labor
  • Consistent quality — every component passes dimensional inspection before packing
  • This is not a "steel kit." This is a fully engineered structure, designed to your local wind, snow, and seismic loads.

Full Code Compliance — Wherever You Build

  • We don't ship a "generic" building and hope it passes. Every structure is engineered to your specific location's requirements:
Standard Application Region
EN 1090-2 EXC2/EXC3 Europe, UK, Middle East
UKCA / CE Marking United Kingdom, European Union
NBCC + CSA S16 Canada
AISC 360 / ASCE 7 United States, Caribbean
AS/NZS 1170 Australia, New Zealand, Pacific Islands
SANS 10160 / SANS 10162 South Africa, Sub-Saharan Africa
 
  • What you get: A full documentation package — structural calculations, material certificates, weld procedure specifications (WPS), NDT reports, and declaration of performance (DoP) where required.

 

Bolt-Together System — No Site Welding

 

  • Every connection in our steel frames is designed for bolted assembly. Your crew needs:
  • A mobile crane or telehandler
  • Basic hand tools and torque wrenches
  • Our color-coded erection drawing set
  • No welding machines. No on-site NDT. No weather delays waiting for weld inspections.
 

Factory Pre-Assembly Inspection

  • Before your steel is packed into containers, we pre-assemble the first structural bay in our factory yard. This isn't just a visual check — we:
  • Verify all bolt hole alignment across column-to-rafter and rafter-to-rafter connections
  • Check base plate flatness and anchor bolt template dimensions
  • Confirm brace lengths and connection angles
  • The inspection report — with photos and measurement data — is included in your shipment documentation. When your containers open on site, there are no surprises.
      Custom Engineering for Your Climate
  • Not all steel buildings are the same. We design to your actual environmental loads:
Load Type Design Range Example
Snow load Up to 5.0 kPa Northern Canada, Scandinavia, Alps
Wind speed Up to 250 km/h (70 m/s) Hurricane zones, coastal Australia
Seismic Zone 0 to Zone 4 New Zealand, Japan, Chile
Temperature -45°C to +50°C Arctic to desert environments

Corrosion Protection That Lasts

  • Steel only lasts if it's protected. Our standard finish is hot-dip galvanizing to ≥ 85μm zinc thickness, tested to ISO 1461. For coastal or aggressive environments, we offer:
  • Heavy galvanizing (≥ 140μm)
  • Duplex system: galvanizing + epoxy primer + polyurethane topcoat
  • Stainless steel fasteners (A2-70 / A4-80 grade) for critical connections
  • Corten (weathering) steel upon request

Optional Features

  • Overhead crane runway beams (up to 50T capacity)
  • Mezzanine floor systems (steel deck + reinforced concrete)
  • Ventilation: ridge vents, turbine ventilators, louvered sidewall openings
  • Natural lighting: FRP skylight panels (translucent, UV-stabilized)
  • Insulated sectional doors, high-speed roller doors, aircraft hangar sliding doors
  • Rainwater gutter and downpipe systems
  • Fire protection: intumescent coatings up to 2-hour rating

Frequently Asked Questions

 

  • How long does it take from order to delivery?
  • Typical timeline: design & engineering 15–25 working days + fabrication 25–50 working days + ocean freight (varies by destination; e.g., 22 days to West Africa, 30 days to Europe, 35 days to East Coast North America). Most projects arrive on site within 10–14 weeks of order confirmation.
  • Can you handle the structural design and calculations?
  • Yes. Our in-house engineering team produces a complete structural package — frame analysis, connection design, foundation reaction tables, and anchor bolt layouts — referenced to your local building code. We can also coordinate with your local engineer of record for plan review and permit submission.
  • What about installation? Do you provide site supervision?
  • We strongly recommend our site supervision service for first-time clients: an experienced erection supervisor travels to your site to guide your local crew through the assembly. For repeat clients with trained crews, the bolt-together system is designed for self-erection using our color-coded manual.
  • Do you provide CE / UKCA certification?
  • Yes. Our fabrication facility holds EN 1090-2 EXC3 certification (the highest execution class for steel structures). We issue a Declaration of Performance (DoP) and CE/UKCA marking for all shipments to the European Union and United Kingdom.
  • What is the minimum order?
  • There is no fixed minimum — we handle everything from a single 200㎡ farm shed to a 30,000㎡ multi-building industrial park. Pricing per square meter improves with volume, but we treat every project with the same engineering rigor.
  • How is the steel packed and shipped?
  • All components are bundled, labeled, and containerized with a detailed packing list keyed to the erection drawings. Bolts and small accessories are packed in clearly marked plywood crates. We use export-grade fumigated timber dunnage and VCI (volatile corrosion inhibitor) wrapping for ocean freight.

Get Your Project Started — 3 Simple Steps
  • Step 1 — Send Your Requirements Share your building dimensions, location, and intended use. A rough sketch, satellite image, or reference photo helps — but even just "I need a 20m × 40m warehouse in Mombasa, Kenya" is enough to start.
  • Step 2 — Receive Your Custom Proposal Within 2–3 working days, you'll receive a preliminary structural layout, a bill of materials with pricing, and a shipping estimate — all free of charge and with zero obligation.
  • Step 3 — We Engineer, Fabricate, and Ship Once you approve the detailed shop drawings, fabrication begins. We'll keep you updated with progress photos and container tracking numbers until your steel arrives on site.
