6m x 3m footprint (5,960 x 3,000 mm) in flat (R1R) and skillion (R1S) roof. 4.5 mm galvanised main structure, 2.3 mm beams and arms, 1.2 mm base joists and roofing members, four-layer powder-coated. 8 lifting points on every profile. Crate 535 to 590 kg, flat-packed, one kit fills a 40ft container.
A container frame is a structural component, so compliance sits with the completed building. In Australia that means NCC 2022, with cold-formed steel design to AS/NZS 4600, load actions to AS/NZS 1170, and galvanised corrosion protection to AS/NZS 4680. Final building approval rests with the local council.
Bolt-together galvanised steel, no welding, assembled in a few hours. Flat-packed in a steel crate with 8 lifting points, so it lifts off the truck without hand loading. Takes a 19 or 25 mm subfloor, 50 mm EPS or framed walls, and a Colorbond roof. Frames join side-by-side or end-to-end and can be cut to size.

Overview
What Is a Container Frame?
A container frame is the steel skeleton of a building, supplied as a bolt-together kit. Buyers searching for a shipping container frame want the frame on its own: the posts, beams and roof members, ready to clad and fit out. SCS supplies that as a container frame kit in galvanised steel, on a 6m x 3m footprint, in two roof profiles on the same steelwork: flat (R1R) at 2,700 mm, and skillion (R1S) sloping from 2,650 to 3,000 mm to shed water. Both take the same cladding, roof and flooring, and frames join or cut to size.
Build
How the Frame Goes Together
Every frame is a flat pack container frame: it ships in a steel crate and bolts together without welding. The galvanised steel carries a four-layer powder coat, and most kits assemble in a few hours with basic equipment. It takes a 19 or 25 mm subfloor, 50 mm EPS or framed walls, and a Colorbond roof. SCS builds at its own Yixing, Jiangsu factory; every FlexiFrame order ships with a new 40ft High Cube container, and sold-separately shower modules and PA doors with a new 20ft General Purpose container.
Compliance
Australian Compliance and Build Standards
A container frame is a structural component, so compliance sits with the completed building rather than the kit alone. In Australia that means the National Construction Code (NCC 2022). The cold-formed steel sections are designed to AS/NZS 4600, the structure's load actions, including Region D cyclonic wind in cyclone-prone areas, to AS/NZS 1170, and the galvanised corrosion protection to AS/NZS 4680. Final approval for container frames in Australia rests with the local council or building surveyor, and what's required depends on the state, the land zoning and the finished use. The maritime container marks you see on freight containers cover shipping, not steel building frames, so they don't apply here. What matters is the structural and building compliance of the finished structure on the frame.

Frequently Asked Questions
Three questions buyers ask most often about container frames.
What is a container frame used for?
A container frame is the structural steel shell for a relocatable or modular building. Builders and resellers use it for tiny homes, site offices, granny flats, carports, modular extensions and pop-up retail, cladding and fitting it out to suit the project.
How long does it take to assemble a container frame?
Most kits bolt together in a few hours with basic equipment and no welding. The frame arrives flat-packed in a steel crate with 8 lifting points, so the main on-site work is setting the crate down, bolting the frame up and squaring it before you clad and roof it.
What is the difference between the flat and skillion roof frames?
Both share the 6m x 3m footprint and steelwork. The flat roof is the compact, economical base at 2,700 mm. The skillion roof slopes from 2,650 to 3,000 mm to shed water and give more overhead space at the high end.
