Independent buyer-side procurement reference
Steel structure procurement guidance for EPC buyers
Prepare RFQs, evaluate fabricators, review factory and quality evidence, and plan export delivery before supplier award.
General procurement reference—not engineering design advice. Project specifications, approved drawings, and authorized engineering decisions take priority.
The five-stage buyer path
Use each stage to move from a clearer quotation basis to a more controlled project handover.
Define the RFQ
Clarify project scope, drawings, requirements, exclusions, and commercial terms.
Evaluate the fabricator

Verify factory capability
Check production flow, equipment, welding, coating, and quality controls.
Control quality documents
Review traceability, inspection, test, repair, and release records.

What information should be included in a steel structure RFQ?
A steel structure RFQ should define the package scope, drawings and revisions, materials and standards, connection responsibilities, inspection requirements, commercial assumptions, schedule, marking, packing, and delivery expectations.
Which documents matter before supplier award?
Before supplier award, buyers should check the quotation basis, clarification record, capability evidence, quality plan, document list, proposed schedule, subcontracting assumptions, and the supplier's response to project requirements.
Is EPC Steel Guide a manufacturer or engineering designer?
No. EPC Steel Guide is an independent buyer-side procurement reference. Its guidance does not replace approved design documents, project specifications, engineering decisions, or supplier due diligence.
