| Procurement Item | Details |
|---|---|
| Applicable Standard | EN 10025-2 |
| Product Category | Steel Plates & Coils / Plate |
| 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
- A defined general structural grade supports alignment with European drawings, purchase lists and inspection documents.
- Quote cut edges, mill edges and pickled surfaces separately to match subsequent processing.
- Review different sizes together to clarify nesting, material utilization and individual piece weight.
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 t / mm | 3, 4, 5, 6, 8, 10, 12, 14, 16, 18, 20 | For thicker material, specify and verify the applicable grade thickness group separately. |
| Width W / mm | 1000, 1250, 1500, 1800, 2000, 2200, 2500 | Confirm nesting separately for parent plates and cut parts. |
| Length L / mm | 2000, 2500, 3000, 6000, 12000 or drawing-based cutting | Check net length and handling clearance for export loading. |
| Dimensional Tolerances | EN 10029 for heavy plate; EN 10051 for continuously hot rolled flat products | Specify thickness tolerance class, flatness and edge condition. |
| Delivery Condition | +AR as rolled; +N normalized / normalizing rolled by agreement | +AR must not automatically be treated as +N. |
| Edges & Processing | Mill edges, sheared edges; levelling, cut-to-length and cutting requirements may be submitted. | Dimensional combinations and processing capability are confirmed in the quotation. |
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
- Check changes in carbon limits and yield strength between thin and thicker products; the S235 designation alone is insufficient for acceptance.
- Check thickness, width, length, flatness and edge condition. For painting, specify scale removal and surface preparation.
- State bending radius and direction for cold bending. General structural steel is not automatically a deep-drawing grade.
- Link inspection documents to heat numbers. Specify witnessed or actual impact testing in advance where required.
06 / Export Packaging for This Product
| Stage | Recommended Arrangement | Key Considerations |
|---|---|---|
| Surface Protection | Apply temporary rust-preventive oil to carbon steel as agreed. Stainless steel may use protective film and interleaving where required. | Rust preventive must be compatible with subsequent painting and welding. |
| Stacking & Edge Protection | Stack matching sizes evenly on level supports; use protection between corners and steel straps. | Prevent localized dents and exposed-edge damage. |
| Handling & Loading | Select bases and strapping according to package weight, centre of gravity and forklift / lifting equipment. | Check container payload and floor point loads; available volume alone does not determine a safe load. |
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.
