Engineering Teardown

We publish every spec. Most importers won't.

Ask any supplier three questions: tare weight, fire rating, and steel gauge. If they can't answer — that tells you everything.

⚙️

3.8-Tonne Chassis

Full-Galvanized Q235 Steel Frame

3.8ttare weight

Main beams 100×100×2.5mm. Columns 150×150×2.5mm. Crane lifting points 6mm galvanized steel. Full hot-dip galvanized coating — zero rust, zero frame deflection under single-point crane lift.

Cheap imports: 1.5mm thin-wall steel, under 2.5 tonnes ❌
🔥

Class A Fire Rating

75mm Rock Wool Sandwich Insulation

100mmtotal wall system

Class A = non-combustible. Period. Not B1 "flame-retardant", not EPS foam that melts. Our 75mm rock wool sandwich panels simply will not burn. Plus 9mm bamboo-fibre interior + 16mm metal-clad exterior = 100mm total wall thickness.

Cheap imports: 50mm flammable EPS foam (burns in seconds) ❌
⚡

12KW Pre-Wired System

RCD-Protected Electrical Throughout

6mm²mains cable

20A RCD safety switch. Mains cable 6mm². Hot water 6mm². Air-con sockets 4mm². General power 2.5mm². Lighting 1.5mm². Every circuit is pre-wired at the factory — your local sparky just connects to mains.

Cheap imports: single thin cable, no RCD, DIY wiring ❌

Full BOM Specification — 20ft Expandable (37m²)

Frame Structure (Q235 Galvanized)

  • Main top beam — 100×100×2.5mm square tube
  • Main bottom beam — 80×80×2.5mm square tube
  • Columns — 150×150×2.5mm square tube
  • Crane points — 150×150×160mm @ 6mm thick
  • Wing frames — 40×80×2mm tube
  • Fold hinges — 3mm galvanized steel

Insulation & Cladding

  • Walls — 75mm rock wool sandwich (Class A)
  • Interior — 9mm bamboo-wood fibre panel
  • Exterior — 16mm metal-clad carved panel
  • Roof — 0.5mm colour steel + glass wool

Floor System

  • Base — 18mm fire-rated cement board
  • Surface — 2mm PVC wood-grain vinyl

Doors & Windows

  • 8× aluminium windows (930×1000mm)
  • 1× thermal-break aluminium entry door
  • 2× interior steel doors
  • 1× frosted glass bathroom door

Electrical (12KW)

  • 20A RCD safety switch
  • Pre-wired: 6mm² mains, 4mm² AC, 2.5mm² GPO
  • LED ceiling lights throughout

Every number above comes from our factory BOM (Bill of Materials). We publish them because most importers can't — they don't know what's inside their own product.
