| Procurement Item | Details |
|---|---|
| Applicable Standard | EN 10025-2 |
| Product Category | Steel Plates & Coils / Coil |
| Dimensions & Quantity | The sizes below are enquiry references. Available combinations, quantities and delivery times are subject to written quotation. |
| Documentation | Specify heat/batch inspection documents, standard edition, traceability and project certification in your enquiry. Documents are subject to confirmation of actual availability. |
01 / Product Features & Selection
- Specify master coil, slitting or cut-to-length requirements to control yield and delivered dimensions.
- Choose black or pickled-and-oiled surface according to subsequent coating, welding and forming.
- Trace slit coils and cut sheets to the original heat / master coil, rather than relying on appearance.
02 / Specifications, Dimensions & Ordering Options
These dimensions help define your purchase requirement; they do not imply that every combination is in stock. Specify tolerances, quantity, delivery condition and destination port. Submit drawings for special sizes.
| Parameter | Specification / Enquiry Range | Points to Confirm |
|---|---|---|
| Thickness / mm | 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 16, 20 | For 1.5–3 mm, verify thin-gauge strength and A80 clauses separately. |
| Width / mm | 600, 900, 1000, 1219, 1250, 1500, 1800, 2000 or slit widths | Confirm thickness-width combinations and minimum slit width. |
| Coil Inside Diameter / mm | 508 or 610, subject to production and the buyer's uncoiler. | Specify eye orientation as well as outside diameter. |
| Individual Coil Weight | Agree according to uncoiler capacity, transport and handling conditions. | State maximum permitted coil weight and outside diameter. |
| Edges | Mill, trimmed or slit edges | Confirm burr direction, height and camber. |
| Supply Form | Master coil, recoiled, slit or cut-to-length requirements may be submitted. | Distinguish parent-coil testing from post-processing dimensional acceptance. |
| Dimensional Tolerances | EN 10051 for continuously hot rolled coils | Agree the flatness inspection method after levelling. |
| Thin-Gauge Supplement (Transverse) | Yield Strength ReH / MPa | Tensile Strength Rm / MPa | Minimum Elongation A80 |
|---|---|---|---|
| 1.5<t≤2 mm | ≥235 | 360–510 | ≥17% |
| 2<t≤2.5 mm | ≥235 | 360–510 | ≥18% |
| 2.5<t<3 mm | ≥235 | 360–510 | ≥19% |
03 / Standard Chemical Composition
EN 10025-2. Values are mass percentages (%). Maximum limits are shown by ≤, minimum limits by ≥; ranges are specification limits and Fe is the balance. These are not measured results for a current delivery heat.
| Element / Indicator | Requirement or Range |
|---|---|
| C | ≤0.17 (3–20 mm reference range on this page) |
| Mn | ≤1.40 |
| P | ≤0.035 |
| S | ≤0.035 |
| N | ≤0.012 |
| Cu | ≤0.55 |
| Si | Check the contractual standard; not specified in this grade table. |
| Fe | Balance |
Heat analysis, mass %. Based on Tata Steel public thin-gauge data to EN 10025-2:2004. Outside the stated thickness range, reconfirm product form and contractual standard edition; do not extrapolate. Nitrogen-binding exceptions follow the standard.
04 / Mechanical Properties & Application Limits
| Thickness / Material Condition | Yield Strength Re / Rp0.2 (MPa) | Tensile Strength Rm (MPa) | Elongation After Fracture A (%) |
|---|---|---|---|
| 3≤t≤16 mm, transverse specimen | ≥235 | 360–510 | ≥24 |
| 16<t≤20 mm, transverse specimen | ≥225 | 360–510 | ≥24 |
Strength in MPa; A is elongation on a proportional specimen (%). Transverse values follow Tata Steel public data. Do not interchange longitudinal section values with sheet A80 requirements. JR indicates +20°C / 27 J; confirm actual testing and specimen size when ordering.
05 / Inspection, Processing & Quality Checks
- Verify S235JR, rolling condition and dimensional range; commercial-quality coil is not automatically equivalent.
- Check master / slit coil numbers, net weights and labels. Specify actual or theoretical weight settlement.
- Inspect telescoping, loose winding, edge cracking, scale and transport dents.
- State pickling, oiling and forming requirements explicitly; general structural properties do not establish process suitability.
06 / Export Packaging for This Product
| Stage | Recommended Arrangement | Key Considerations |
|---|---|---|
| Coil Protection | Moisture barrier, inner / outer edge rings, end protection and steel straps as appropriate to the finish. | Prevent edge damage, telescoping and coil-end impact. |
| Securing Method | Horizontal cradles or vertical pallets to suit the customer's handling arrangement. | Prevent rolling; specify eye orientation and individual coil weight. |
| Moisture Control & Unpacking | Pack dry material; inspect for condensation on arrival before unpacking. | Sealed, damp storage can cause white rust on galvanized steel. |
Before shipment, cross-check product, grade, heat number, size, piece count, net weight and gross weight against the packing list. Match labels to inspection documents. For solid-wood pallets, dunnage or crates, check destination-country rules; wood subject to ISPM 15 must be treated and marked by an approved provider. Load dry cargo and arrange supports, blocking and securing according to weight and centre of gravity.
07 / How Qida Supports Your Procurement
| Procurement Stage | Qida Coordination | Information for the Buyer |
|---|---|---|
| Requirement Review | Review application, standards, material condition, drawings and acceptance items. | A checkable specification list helps reduce language and unit-conversion errors. |
| Order Confirmation | Confirm material, processing, inspection, packaging, delivery milestones and cost responsibilities item by item. | A clear written quotation and mutually agreed purchase requirements. |
| Delivery Coordination | Coordinate production / sourcing progress, labels, packing lists and shipping documents. | Check dimensions, quantities and heat/batch correspondence at agreed milestones. |
| After-Sales Follow-Up | Review issues using order number, heat number, arrival photographs and test records. | A defined issue description and documented resolution communications. |
Qida focuses on clear specifications, material requirement checks and delivery coordination. Include cutting, cut-to-length, surface treatment, third-party inspection and certificate requirements in your enquiry so that the achievable scope can be agreed before order placement.
