Steel Frame Warehouse

Product Introduction

01Product Overview

Prefab steel frame warehouse building with clear span

A steel frame warehouse is a prefabricated storage building built on a bolted portal-frame steel skeleton with color-coated or sandwich-panel cladding. It gives you a large, column-free interior for racking, forklifts and cargo flow. As a dedicated steel frame warehouse manufacturer, BBN Steel supplies the primary frame, purlins, wall / roof panels, doors, windows and crane beams — engineered for your local wind, snow and seismic loads.

02Professional Steel Frame Warehouse Types

All types share a bolted, prefabricated portal frame for fast on-site assembly. Choose by span, height, crane and insulation need.

Clear-Span Portal

Single rigid frame, no interior columns. The standard steel frame warehouse for wide, open storage.

Multi-Span

Two or more column rows for very large footprints; economical above 30 m width.

Mezzanine Floor

Internal intermediate floor doubles usable area for parts, office or picking.

Lightweight Prefab

Light-gauge steel for small depots and agricultural bulk storage, fast and cheap.

Steel Truss Shed

Triangulated truss roof for large clear spans and heavy snow / crane loads.

Cold-Storage Insulated

PU / PIR sandwich panels keep temperature; ready for reefer and low-temperature use.

03Applicable Warehouse Scenarios

Our prefab steel warehouses fit logistics, industry and agriculture. Common deployment scenarios:

Logistics Distribution Center

Column-free interiors for high-bay racking, forklift aisles and fast in/out flow.

Factory Storage

Raw-material and finished-goods sheds attached to production lines, crane-ready.

Cold Storage Warehouse

Insulated prefab warehouses for frozen / chilled goods, with vapor barrier design.

E-commerce Fulfillment

Mezzanine-equipped warehouses for picking, packing and returns processing.

Agricultural Bulk

Grain, feed and machinery storage sheds, naturally ventilated and low cost.

Equipment Shelter

Vehicle, generator and plant shelters with wide doors and optional crane beam.

04Steel Material & Grade Selection

We build warehouses in the full range of structural grades. Grade is selected by span, environment and load — the first driver of a durable steel frame warehouse solution.

Q355B (Q345B)	GB/T 1591	355	Main frames of medium / large warehouses
SS400	JIS G3101	245	General frame members for Asia projects
S355JR / S355J2	EN 10025-2	355	EU main frames, J2 for low-temperature impact
A36	ASTM A36	250	North America project frames
Q355GNH (weathering)	GB/T 4171	355	Low-maintenance outdoor frames, no paint needed

08FAQ

Q1Are you a steel frame warehouse manufacturer or a trading company?

We are a direct steel frame warehouse manufacturer with our own fabrication plant and QC team. You buy from the source, which is why our prefab warehouse cost is competitive and lead times are controllable.

Q2What is the cost of a prefab warehouse?

A typical prefab warehouse cost is USD 35–130 per m² (steel + cladding, ex-works), depending on grade, span, eave height, cladding and crane. Send us the area and load and we return a fixed quote.

Q3Can you customize span, height and crane?

Yes. Span, eave height, bay, roof slope, doors, windows, mezzanine and overhead crane (up to 20 t) are all customizable. Send a site drawing and we return a 3D model.

Q4How do you handle wind, snow and seismic loads?

Every project is engineered to your local code (GB, Eurocode, AISC or ASCE) with wind up to 45 m/s, snow up to 2.0 kN/m² and seismic design where required.

Q5What is the lead time and minimum order?

Typical lead time is 25–70 days by area; we accept small depots (from 300 m²) and full industrial parks alike.
