On an infrastructure or industrial project, steel is rarely the most complicated item on the bill of materials — but it is one of the easiest to get wrong. A grade that is close but not equivalent, a coating that does not suit the site, or a certificate that cannot be traced back to the heat can hold up an entire installation. This guide is for procurement teams and project engineers in the Middle East, Central Asia and Africa who source steel materials from overseas mills.
1. Specify the standard and grade, not just the product name
“Carbon steel pipe” or “stainless plate” is not a specification. Every line on your enquiry should state:
- The standard and grade (for example an ASTM, EN or GB designation), and which equivalents you will accept.
- Dimensions and tolerances: thickness, width, length or coil weight; outside diameter and wall thickness for pipe.
- Delivery condition and surface finish: hot-rolled, cold-rolled, annealed, pickled, galvanised, pre-painted.
- Quantity per item, and whether partial deliveries are acceptable.
When a mill offers an “equivalent” grade, ask for the chemical composition and mechanical properties side by side with the grade you specified before you accept it.
2. Match the material and coating to the site
Coastal sites, high ambient temperatures, chemical plants and desert dust all affect how long steel lasts. The decision is usually between the right base material and the right protection:
- Chloride and chemical exposure — stainless grades such as 316L, or nickel alloys for the most aggressive process conditions.
- Roofing, cladding and enclosures — galvanised or pre-painted coil, with the coating system and paint specification written into the order.
- Structural members and general piping — carbon steel with the coating or painting system defined by your project specification.
If your project has a corrosion engineer or a consultant’s material schedule, send it with the enquiry. It is the fastest way to avoid quoting the wrong thing.
3. Insist on traceable documents
Ask for a mill test certificate for every heat or batch, showing chemical composition and mechanical test results, with heat numbers that match the markings on the material. For critical items, add third-party inspection by a body such as SGS or BV.
4. Agree packing, marking and shipping before production
Coils need protection against moisture and edge damage; pipes need end caps and bundling; plates need proper dunnage. Agree the packing standard, the marking on each bundle or coil, and whether the order ships in containers or as break bulk. Clear marking that matches the packing list makes receiving and site storage much faster.
5. Build a realistic schedule
Ask for the production and shipment schedule in writing, and decide early which items are critical to your construction sequence. Splitting the order so that critical items ship first is often better than waiting for the whole quantity.
How we work on steel orders
YuxingCorp coordinates steel supply from mills and manufacturers we have visited and qualified, and handles supplier coordination and shipping and freight logistics coordination for you. Every order ships with a complete export document pack — commercial invoice, packing list, certificate of origin and bill of lading — together with the mill test certificates. Third-party inspection (e.g. SGS, BV) is available on request; the fee is paid by the buyer. Import customs clearance, duties, taxes and local registration are the buyer’s responsibility. Our standard payment terms are T/T: 30% deposit and 70% before shipment.
Browse our steel materials and coils — carbon steel, stainless steel, aluminium, coated steel, pipes and tubes — or see two steel supply projects: structural steel for an EPC project in Africa and steel supply for an infrastructure EPC project.
