Overseas steel structure procurement risks often begin before the purchase order is issued. If the RFQ is incomplete, the quotation may contain hidden assumptions. If the supplier is not reviewed properly, production capacity, quality records, coating control, or export packing may become problems after award.
This guide is written for EPC buyers preparing steel structure packages for industrial buildings, logistics warehouses, workshops, platforms, and other export projects. It focuses on practical controls that can be added before supplier selection.
1. Scope gaps in the RFQ
A common risk is that suppliers quote different scopes. One quote may include shop drawings, bolts, secondary steel, painting, packing, and loading records. Another quote may exclude several of those items.
| Risk | Control before award |
|---|---|
| Missing secondary steel | List purlins, girts, bracing, stairs, handrails, platforms, and small supports separately. |
| Unclear bolt scope | Define anchor bolts, high-strength bolts, nuts, washers, and small accessories. |
| Design responsibility unclear | State whether the supplier provides shop drawings, connection design, or only fabrication. |
Use the EPC steel structure procurement checklist to define the package before RFQ release.
2. Incomplete drawings and assumptions
Incomplete drawings lead to provisional pricing. EPC buyers should state which drawings are final, which are preliminary, and which information is missing. Suppliers should be required to list assumptions instead of hiding them in the price.
- General arrangement drawings are missing dimensions or elevations.
- Connection details are not defined.
- Material grades, loads, or design code are unclear.
- Interface points with cladding, cranes, equipment, or civil works are missing.
For the drawing package, see steel structure quotation drawings EPC buyers need.
3. Quote comparison risk
The lowest price may not be the lowest project cost. A quote can look cheaper because it excludes documents, coating, packing, bolts, inspection, inland transport, or special delivery requirements.
| Comparison item | Question to ask |
|---|---|
| Weight basis | Is the quote based on theoretical weight, drawing weight, fabricated weight, or shipping weight? |
| Commercial terms | Are Incoterms, currency, validity, payment, and delivery basis comparable? |
| Exclusions | Are design, inspection, coating, packing, freight, taxes, or site works excluded? |

4. Factory capacity risk
A supplier may claim high capacity but still fail the schedule if the workshop is overloaded or key processes are bottlenecks. Buyers should check current workload, realistic monthly output, equipment condition, coating capacity, and subcontracted work.
- Ask for recent monthly production records.
- Check whether blasting and painting capacity matches the schedule.
- Review subcontracted cutting, welding, coating, or packing work.
- Ask for a production plan tied to drawing approval and shipment batches.
5. Quality document risk
Overseas projects often need document packages for owner review and handover files. If the required documents are not in the RFQ, they may be incomplete or treated as extra work after production.
- Material certificates and traceability records.
- Welding procedure, welder qualification, and inspection records.
- Dimension inspection records.
- Coating inspection and dry film thickness reports.
- Packing list, marking list, and loading photos.
The steel structure quality documents guide can be used as a document request list.
6. Coating and surface treatment risk
Coating problems can appear after sea freight or site unloading. Define surface preparation grade, paint system, dry film thickness, curing time, repair method, and inspection records before award.
For export coating requirements, use the surface treatment requirements guide.
7. Export packing and site sorting risk
Poor packing can cause coating damage, missing small parts, unclear component marks, slow unloading, and erection delays. The packing plan should match component marks, bundle labels, packing lists, and site installation sequence.
- Components should be marked consistently with drawings and packing lists.
- Small parts should be packed by building area or shipment batch.
- Bundle labels should show component range, weight, and handling notes.
- Loading photos should be provided before shipment.
8. Communication and time-zone risk
Overseas procurement depends on clear communication. Slow clarification can delay shop drawings, material purchase, inspection, and shipment. Buyers should define response windows, document language, approval workflow, and the person responsible for technical clarification.
Risk control checklist
- Send the same RFQ package to every shortlisted supplier.
- Ask suppliers to list assumptions and exclusions line by line.
- Request sample quality documents before award.
- Check production capacity against current workload, not only stated maximum capacity.
- Define coating, packing, marking, and delivery records before production starts.
- Keep all clarification records tied to drawings, component marks, and shipment batches.
Buyer note
Most overseas steel structure procurement risks are easier to control before award than after fabrication starts. A clearer RFQ, consistent quote comparison, documented factory review, and export packing plan can reduce cost changes and site delays.
