3 Bay Compliant Modular Building
The 3 Bay Compliant Modular Building is a high-specification modular solution designed for businesses, organisations and project teams that need flexible, spacious accommodation. With a robust steel framework, insulated wall system and a range of internal and external finish options, it can be configured for offices, training facilities, sports clubhouses, canteens and meeting spaces.
The modular design allows units to be linked side-by-side or end-to-end, making it possible to create larger open-plan areas and adapt the building to changing requirements.
Key Features
Robust Steel Construction
The building incorporates a strong structural framework consisting of:
- Hot-rolled steel ring beams
- Galvanized steel floor joists
- Steel corner columns
- Steel lattice roof beams
The system can provide clear spans of up to 12m (40ft), depending on the final configuration and design requirements.
It has a stated floor loading capacity of 5 kN/m² and roof loading capacity of 0.75 kN/m², providing a solid structural platform for a range of commercial applications.
Durable Roof System
The roof is constructed using 15mm tongue-and-groove timber decking with a Fatra Eco Pro PVC fire-rated membrane. Soffit construction and uPVC rainwater goods complete the roof system.
Customers can choose between:
- Mono-pitched roof
- Dual-pitched roof
The roof configuration can be selected according to the requirements of the building and project.
Insulated Wall Construction
The wall system combines timber studs with plastisol-coated steel cladding for a durable external finish.
The building incorporates 90mm fiberglass insulation together with Eco Brit foil therm insulation. Internally, the walls can be finished with 12.5mm or 15mm plasterboard and uPVC architraves.
The insulation specification can also be upgraded where specific U-value requirements need to be met.
Flexible Interior Options
The 3 Bay Compliant Modular Building can be specified with a choice of finishes and fittings to suit its intended application.
Available options include:
- 2.4m, 2.7m or 3m ceiling heights
- Vinyl flooring
- Carpet tiles
- Non-slip flooring
- uPVC windows and doors
- Powder-coated aluminium windows and doors
- Steel multi-point locking windows and doors
This flexibility makes it possible to create a professional environment suited to office, training, welfare or community use.
Expandable Modular Design
The modular construction allows units to be connected side-by-side or end-to-end, providing additional flexibility when more space is required.
This makes the system suitable for projects where accommodation requirements may change over time. Additional units can be incorporated into a larger modular layout depending on the available site and project specification.

Buying a modular building: what to check
A portable cabin or container office is ready to use on arrival, so the questions are about layout and services. Check the internal size, the number and position of doors and windows, insulation, lighting and power sockets, and whether you need heating or air conditioning. For welfare and toilet units, plan the water supply and the waste connection or a waste tank. Jackleg cabins can be lifted on and off a truck on their own legs; other units need a crane or forklift to offload. Make sure the ground is firm and level, and know where power will come from before it arrives.
Convex Containers is based in Broken Arrow, Oklahoma, in the Tulsa area, and sells shipping containers, refrigerated containers, container pools, portable cabins, flat pack buildings and trailers to buyers across the United States.
