Modular Office Buildings

The load-bearing structure comprises a welded floor frame, roof frame and corner posts made from 3 mm galvanized, coated steel profiles. The modular design allows containers to be positioned individually, arranged side by side or combined into larger facilities. Wall openings and internal partitions can be planned around the required layout. Stacked solutions are possible where the project-specific structural design, foundations and approvals permit them.

The flat roof uses a welded steel frame and a galvanized sheet-steel outer skin with sealed double seams. Mineral-wool or rigid-foam insulation and an internal ceiling lining complete the build-up. The insulation and lining are specified for the model, intended use and required thermal performance.

A galvanized, coated steel floor frame with forklift pockets provides the structural base. The standard build-up includes 100 mm non-combustible mineral-wool insulation, an underfloor sheet layer, a 20 mm cement-bonded board and durable, low-smoke, flame-retardant 1.5 mm homogeneous PVC flooring. XPS insulation and alternative floor finishes are available for suitable applications.

External wall elements combine coated galvanized sheet steel, mineral-wool insulation and a durable white internal lining. The same modular principle can be used for partitions, allowing practical layouts with consistent surface finishes. Thermal and acoustic performance depends on the selected wall build-up and openings.

Standard office-container windows use insulating glazing with tilt-and-turn hardware and external roller shutters. Depending on the model and application, options include sliding windows, service hatches, fixed glazing and larger display or showroom glazing. Number, position and dimensions are coordinated with the layout and structural requirements.

Single-leaf steel exterior doors with secure locking are the usual standard. Options include glazed door leaves, double-leaf doors, alternative entrance positions and interior doors. Wider or step-free access, ramps and platform solutions are planned as project-specific access systems rather than assumed as standard.

Factory-installed electrical equipment is adapted to the selected model. Full-size office-container models include a 400 V / 32 A / 5-pin CEE inlet and outlet, a distribution board with RCD protection, separately protected circuits, lighting, switches and sockets. Final equipment and the applicable electrical standards and conformity requirements are confirmed for the project and installation location.

Heating provision depends on the model and configuration. Standard heater quantities for the full-size models are shown in the comparison table; heating remains optional for the 5-ft cabin. Additional electric wall convectors, mechanical extract ventilation and compact or split air-conditioning systems can be specified according to the intended occupancy and operating conditions. Capacity and placement are defined for the container size, glazing, insulation and site conditions.

CHV office containers are produced and checked against the agreed specification. Structural design, fire-performance requirements, electrical documentation and any application-specific approvals or certificates are defined for the selected model, configuration and installation site.
