Bolted Cold-Formed Steel Warehouses & Light Gauge Framing Kits Engineered for Container Export

Up to 24m clear span, bolted S350GD cold-formed portal and lattice truss structures are 35–45% lighter than welded hot-rolled I-beams, pack up to 3× more building area into a single 40ft High Cube container, require zero on-site welding or touch-up painting, and reduce concrete foundation loads by up to 50%.

In P1 Structural Frame Only scope, one 40ft HC container (max 11.85m bundle length, 24.5 tons net payload) accommodates approximately 400–550 m² of CFS warehouse framing, 240–300 m² of two-story LGS residential framing (or up to 6–7 compact 45 m² ADU frames), or up to 1,200 m² of CNC roof trusses.

Structural steel frame-only kits (P1) typically clear customs under HS Code 7308.90, whereas complete prefabricated weather-tight shell or modular camp kits (P2/P3/P4) are classified under HS Code 9406.90. For European Union buyers, industrial steel kits shipped from Türkiye with an A.TR Movement Certificate benefit from 0% preferential customs duty.

Zero site welding is required. Every column, truss chord, stud, and laser-cut gusset plate is CNC pre-punched and inkjet-labeled in our production lines. Local crews assemble the kit using calibrated torque wrenches, Grade 8.8 HDG structural bolts, and EPDM self-drilling fasteners.

Depending on your project country, our Istanbul structural engineering desk designs to Eurocode 3 (EN 1993-1-3) and Eurocode 8 (seismic), AISI S100 / IBC (Americas & Caribbean), BS EN / SCI P402 (UK), DTU 32.3 (France), NTC 2018 (Italy), or Saudi Building Code (SBC).

Standard inland kits use S350GD + Z275 (275 g/m² hot-dip zinc). For coastal sites (<5 km from seawater), Caribbean islands, West Africa, or high-humidity industrial washes, we upgrade the framing to ZM310 (Zinc-Aluminum-Magnesium / Magnelis) for C4–C5 marine corrosion resistance.

Yes. Developers, architects, and general contractors regularly submit custom architectural drawings. Under our P0 Engineering Package, we convert your plans into a 3D BIM LGS/CFS structural model, issue static reports, and credit the engineering fee toward your P1–P4 kit production order.

We work with standard T/T milestone transfers (typically 40% manufacturing deposit, 60% prior to container sealing upon inspection) and irrevocable L/C for large camp or fleet contracts. Every coil carries an EN 10204 3.1 mill test certificate, and third-party SGS/Bureau Veritas or live video trial-assembly inspections are welcomed before loading.
