Pre-Engineered Steel Building Procurement from China

Compare supplier proposals for a pre-engineered steel building against the same site criteria. We coordinate China sourcing for portal frames, warehouses, workshops and hangars, from the first scope sheet through inspection and export handoff.

Illustrative project briefs

The following examples show how an RFQ can be structured. They use illustrative values and describe no completed projects.

36 metre clear span logistics warehouse frame

Warehouse frame and coating scope

A coastal warehouse brief might specify a 36 m clear span. Ask the supplier to separate its coating proposal for primary rafters from the zinc coating on girts. Request the design wind basis and coating repair procedure as separate review items.

Where the frame criteria change

WH

Warehouses

Align dock openings with bracing bays and confirm the working clear height.

HG

Hangars

Specify independent door support loads and movement limits at the jamb.

WS

Workshops

Separate static crane capacity from the vendor’s dynamic wheel loads.

ED

Teaching halls

Include occupancy, egress routes and the envelope performance target in the brief.

Engineering documents available on request

Request blank procurement worksheets. Supplier calculations and certificates are requested against the applicable contract scope and reviewed by the buyer’s designated professionals.
