ZSJH supplies Prefabricated Steel Frames for Warehouses to approved drawings. Columns, roof beams, braces and connection sets are fabricated and marked by building grid for site assembly. The package supports logistics warehouses, distribution storage and industrial stock buildings. Storage layout, vehicle circulation, doors and future extension zones are coordinated before member detailing.
Item | Specification |
Eave height | 6 m reference, customized to drawings. Confirm usable storage and equipment clearance separately. |
Longitudinal grid | 6 / 9 / 12 / 18 m reference options; assess with loads, access and structural design. |
Span | 20 m and above as a reference requirement; state both support-axis span and required clear span. |
Layout example | 60 m length × 24 m width, 24 m axis span, 6 m eave height and ten 6 m bays. Illustrative only. |
Openings and loads | Door size/location, docks, roof dead/live loads, wind/snow and equipment/solar loads where applicable. |
Members and materials | Section geometry; Q235B/Q355B or agreed project grade; separate web, flange and connection plate thicknesses. |
Width on column axes equals one span or the sum of spans; clear width between inner faces can be smaller. Building length follows the bay count and grid. Keep columns and bracing coordinated with aisles, dock doors and rack clearances. Mezzanines, rack-supported structures and crane equipment require their own load and interface definitions. Roof and wall cladding are quoted separately; a fabricated frame package is not automatically a complete warehouse.
4 Frame members and coordinated connections
Item | Specification |
Primary frame | Columns and roof beams with approved base, knee and ridge details. |
Bracing | Designed roof/wall bracing and attachment positions; relocation requires design review. |
Connections | Hole patterns, end plates, stiffeners and designed splices; identify supplied hardware separately. |
Plate thickness | For example, an 8 mm web, 12 mm flange or 20 mm end plate may be recorded in a BOM. These are notation examples, not a warehouse design or standard section. |
Engineer review covers layout, loads, interfaces and transport splits, with design/calculations/BIM detailing available if needed. Manufacture follows written approval of drawings. Welding process and WPS suit the joint: submerged arc welding may be used for suitable built-up long seams, with suitable gas-shielded or shielded metal arc processes for attachments. Agree the welding code, such as AWS D1.1/D1.1M where requested, tolerances and inspection plan. Inspect geometry, holes, interfaces and required welds before surface treatment.
Specify preparation, coating products, DFT and color, or separately review hot-dip galvanizing. Agree material, weld, dimensional and finish records. Mark members by frame/grid reference and identify matching connection sets. Group packing by erection zone where agreed, with packing lists showing marks and quantities. Delivery sequence and temporary erection arrangements are coordinated with the site team.
Storage and access brief → grid and structural review → approved detailing → material preparation and fabrication → inspection and finish → grid marking and grouped packing → shipment for site assembly.
Can all bays be identical?
Door, bracing and expansion bays may require different details.
Does 24 m span guarantee 24 m usable width?
Axis span and clear width differ.
