Materials & standards
Our materials & standards
The materials that go into every unit — from the container body to the wiring — and the standards we work to.
The quality of a converted container comes down to what is behind its walls. These are the materials we commonly use; each product's exact specification is on its product page and spec sheet.
Materials
From the container body to the wiring
Container body
ISO-size steel containers (8ft–40ft High Cube) with a strong frame, corner posts and corner castings.
- New, one-trip or grade A used
- Inspected: frame, floor, doors and rust
Opening frames
Every door and window opening is reinforced with box-section or angle steel so the walls stay rigid.
- Welded and painted with anti-rust paint
Paint & rust protection
Surfaces are cleaned, primed with anti-rust paint and finished in your chosen color.
- Custom colors available
- Company logo can be added
Insulation
Walls and roof are thermally insulated — e.g. glass wool, rock wool or PU — so the space stays cooler and the AC uses less power.
Interior walls & ceiling
Wall panels (e.g. fibre-cement board, PVC or plywood) and a ceiling are fixed to an inner frame.
Flooring
The container's original plywood floor is covered with vinyl, carpet or tiles as needed.
Doors, windows & canopies
Panel or glass doors, sliding aluminium windows with security bars, and canopies over the openings.
Electrics
Cables, breakers, sockets, switches, lights and AC points are installed neatly to the working drawings.
Standards
Standards we work to
ISO dimensions
External container dimensions follow the international ISO 668 standard, so units travel on ordinary trailers and ships.
Approved drawings before production
Every custom order is built from working drawings approved by the customer — size and positions of doors, windows and electrics.
Leak testing
Units are checked for wind and water tightness after the openings are cut and before shipping.
Inspection at handover
Units are handed over after a joint check of the structure, doors and windows, electrics and fittings.
Materials can differ by product and order; the exact specification is stated in the quote.
