Kit Buildings' insulated steel buildings represent the pinnacle of modern prefabricated construction technology. Engineered for businesses requiring permanent, temperature-controlled storage solutions, these structures combine industrial-strength Q355B H-section steel framing with advanced insulation systems.

Our Q355B H-section steel frame construction provides exceptional structural integrity, capable of withstanding extreme weather conditions while maintaining a stable internal environment. The galvanized steel components ensure maximum corrosion resistance, delivering decades of reliable service with minimal maintenance requirements.

The sandwich panel cladding system features integrated 50mm EPS insulation, recognized as the industry standard for thermal performance. This insulation technology creates an effective barrier against temperature fluctuations, protecting sensitive materials and equipment and providing comfortable working conditions for staff.

Each building is manufactured to precise specifications, ensuring consistent quality and dimensional accuracy. The modular design allows for easy expansion or reconfiguration as your business requirements evolve.

Whether you need secure storage for agricultural products, industrial equipment, commercial inventory, or manufacturing operations, our insulated steel buildings provide the perfect balance of strength, efficiency, and value.

We supply comprehensive written installation instructions with every order, complemented by detailed video guides when available. Our expert team is always on hand to provide guidance and answer any questions you may have throughout the installation process.

We provide detailed design drawings for every project. Our engineers carefully craft each plan to meet your exact requirements, with efficiency and structural integrity at the forefront of our design process.

To unload the shelter upon delivery, a forklift with a minimum load capacity of 2000 kg is required. This ensures the safe and efficient handling of the shipment. In cases where a forklift is not available, alternative arrangements can be made, though please note that additional charges may apply for such accommodations.

You can do either. Every order includes comprehensive written installation instructions (and video guides where available), and Kit Buildings can also arrange professional installation if you prefer a turnkey build.

You’ll receive detailed design drawings covering the H-column layout, footing positions, elevations and sections—used to set the posts into concrete and complete the build accurately.

These buildings use an H-column beam frame that must be cemented into the ground. Prepare poured concrete footings to the specified depth and spacing, then set and plumb the H-section columns before frame assembly.

The panels arrive packed in steel crates with frames, insulated panels and fixings. The Frame will arrive in a container which will slide out to be offloaded. Plan suitable site access and lifting equipment for safe unloading and handling of steel members and panel bundles.

A robust H-column beam steel frame (H-section posts concreted into footings) with insulated sandwich panels for walls/roof. Standard insulation is 50 mm EPS, with PIR available; box-profile steel sheeting can be specified where needed.

A competent crew familiar with setting columns in concrete and steel erection. You’ll need layout tools for footing placement, equipment to brace/plumb columns while concrete cures, and standard tools/plant for bolting frames and fixing insulated panels.

Long-term coverage typically includes a 20-year structural warranty on the steel frame and a 6-year warranty on insulated panels (see full terms for exact coverage and exclusions).
