A steel structure warehouse is built around a load-bearing frame of standard steel sections and H-beams, combined with other materials to form a complete building. The frame carries the roof and crane loads, the envelope closes the building, and the result is a light, strong structure that goes up quickly and can be recycled at end of life. CDPH engineers each steel structure warehouse to the project design — there are no fixed per-type numeric parameters, so spans, loads and member sizes are set by the structural calculation for your site and duty, not taken from a catalogue.
Portal frames for warehouse duty
The portal frame is the standard structural form for industrial plants and warehouses. Rafters and columns are moment-connected in the plane of the frame, giving a clear internal volume for racking, circulation and goods handling. Frames are designed for the roof and wind loads of the project location and detailed for efficient fabrication and transport.
CDPH delivers the full service chain for these buildings: design, intelligent manufacturing, sea freight logistics, on-site assembly, and after-sales operation and maintenance. Our engineering team works from your drawings, load requirements and site conditions.
ZM series: the wide-span prefab alternative
Where a project calls for a standardised wide-span solution, the ZM series prefab house provides a defined specification. It is supplied as a hot-galvanised steel frame with a double-pitch roof and is typically used for warehouses, workshops and storage buildings.
| Parameter | ZM series specification |
|---|---|
| Span | 12 m / 15 m / 18 m |
| Eaves height | 6 m |
| Column spacing | 4 m or 6 m |
| Roof slope | Double-pitch, 1:5 |
| Roof live load | 0.3 kN/m² (6 m spacing); 0.50 kN/m² (4 m spacing) |
| Wind load | 0.45 / 0.60 kN/m² |
| Snow load | 0.35 / 0.50 kN/m² |
| Columns | M300 steel, T=3.0 mm, hot-galvanised |
| Purlins | C170, T=2.3 mm, hot-galvanised |
| Doors | Sliding 4000×4000 mm; double 1500×2000 mm; customisable |
| Erection | 10 workers erect about 1,000 m² of structure in 5 days |
| Shipping | About 170 m² of structure per 40 ft container |
