| Product Form |
Select the form that matches the processing equipment and final application. |
Hot-rolled coil, cut-to-length sheet, or hot-rolled plate. |
Coils generally reduce handling and cutting costs; sheets and plates may be better for smaller or fixed-size orders. |
| Steel Grade and Standard |
State both the mechanical grade and the governing standard. |
Structural grades such as ASTM A36, EN 10025-2 S275JR, or JIS G3101 SS400; higher-strength grades may include S355JR or equivalent. |
Do not use grade names interchangeably without confirming yield strength, tensile strength, impact requirements, and chemical limits. |
| Thickness |
Specify nominal thickness and permitted deviation according to the selected standard. |
Common hot-rolled coil range: approximately 1.2–25 mm; plate orders commonly start at about 6 mm and extend beyond 100 mm, depending on mill capability. |
State thickness in millimetres and identify whether the tolerance follows EN, ASTM, JIS, or another agreed standard. |
| Width |
Define the required coil or sheet width, including allowable width tolerance. |
Typical commercial widths are approximately 900–2,000 mm; wider material may be available for specific production routes. |
Confirm whether the width is mill edge, slit edge, or trimmed edge. |
| Length |
For cut sheets or plates, specify fixed length and cutting tolerance. |
Common cut lengths include 2,000–12,000 mm; exact availability depends on thickness, width, and transport limits. |
For coils, specify maximum outside diameter, inside diameter, and maximum coil weight instead of sheet length. |
| Mechanical Properties |
Define minimum yield strength, tensile strength, and elongation where performance is critical. |
For common structural grades, yield strength is often around 235–355 MPa, with tensile strength commonly around 360–630 MPa, depending on grade and thickness. |
Require a material test certificate showing actual batch results rather than relying only on nominal grade values. |
| Surface Condition |
Identify whether ordinary hot-rolled scale is acceptable and whether descaling is required. |
As-rolled surface, pickled and oiled surface, shot-blasted surface, or prepared surface for subsequent coating. |
Pickled and oiled material typically costs more but can reduce scale-removal work before forming or painting. |
| Edge and Flatness |
Specify mill edge or trimmed edge and define flatness requirements for fabrication. |
Mill edge for general fabrication; trimmed edge for tighter dimensional control; standard or restricted flatness. |
Confirm edge quality if the material will be laser cut, roll formed, welded, or visibly exposed. |
| Order Quantity |
State total net weight, number of pieces or coils, and quantity tolerance. |
Sample or trial orders: 1–5 tonnes; regular commercial orders: approximately 20–100 tonnes; project orders may exceed 500 tonnes. |
Ask for the minimum order quantity, permitted shipment-weight variance, and whether mixed sizes or grades are allowed. |
| Coil or Bundle Weight |
Define handling limits for cranes, decoilers, trucks, and storage equipment. |
Common coil weights are approximately 5–30 tonnes; sheet bundles are often about 2–5 tonnes, subject to handling requirements. |
A lower maximum unit weight may increase the number of bundles or coils and affect freight cost. |
| Packaging and Protection |
Specify waterproof wrapping, steel or fibre strapping, edge protection, and skid requirements. |
Standard export wrapping, full hard-cover protection, corrosion-inhibiting paper, or container-compatible packaging. |
Packaging should match the transport mode, storage duration, humidity exposure, and unloading equipment. |
| Inspection Documents |
List the documents required before shipment and at customs clearance. |
Commercial invoice, packing list, certificate of origin, bill of lading, material test certificate, and inspection report when required. |
Ensure the heat number, grade, dimensions, and net weight match across the certificate and shipping documents. |
| Delivery and Trade Terms |
Define destination port or site, delivery date, Incoterm, and required transport mode. |
Common terms include EXW, FOB, CFR, CIF, and DAP; ocean freight is generally used for bulk international shipments. |
Compare total landed cost, including product price, freight, insurance, duties, inspection, port fees, inland delivery, and taxes. |
