01 / Product Features & Selection
- Unequal legs offer selection options for restricted space and connection layouts.
- A higher yield grade with defined thickness groups aligns engineering drawings and procurement.
- Identify long / short legs, hole positions and orientation to avoid mixing left-hand, right-hand and mirrored parts.
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 |
|---|---|---|
| Leg Combination a×b / mm | 60×40, 75×50, 80×40, 90×60, 100×65, 100×75, 120×80, 125×75, 150×90, 150×100, 200×100, 200×150, 250×90 | Check actual series and sizes against EN 10056 catalogues / drawings. |
| Thickness t / mm | 5, 6, 7, 8, 9, 10, 12, 14, 15, 16, 18, 20 | Confirm leg / thickness combinations; arbitrary combinations may be unavailable. |
| Size Designation | a×b×t + length; leg orientation and hole datum | Mark left / right and mirrored parts with separate drawing numbers. |
| Dimensional / Shape Tolerances | EN 10056-1 / EN 10056-2 | Radii, squareness and twist affect assembly. |
| Length / Surface | 6, 9, 12 m or fixed lengths; hot rolled black / subsequent corrosion protection | Confirm chemistry and completed processing before galvanizing. |
03 / Standard Chemical Composition
EN 10025-2:2019 / S355JR (hot rolled sections). 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 | ≤0.24 |
| Si | ≤0.55 |
| Mn | ≤1.60 |
| P | ≤0.040 |
| S | ≤0.040 |
| N | ≤0.012 |
| Cu | ≤0.55 |
| CEV | ≤0.45（t≤30 mm）；≤0.47（30<t≤140 mm） |
| Fe | Balance |
From the ArcelorMittal EN 10025-2:2019 hot rolled section table. Heat analysis, mass %. Nitrogen-binding exceptions and special galvanizing chemistry follow the standard. Do not interchange this section table with another edition / product form used for plate.
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 | ≥355 | 470–630 | ≥22 |
| 16<t≤40 mm | ≥345 | 470–630 | ≥22 |
| 40<t≤63 mm | ≥335 | 470–630 | ≥21 |
| 63<t≤80 mm | ≥325 | 470–630 | ≥20 |
| 80<t≤100 mm | ≥315 | 470–630 | ≥20 |
| 100<t≤140 mm | ≥295 | 450–600 | ≥18 |
Strength in MPa, proportional elongation A in %. Nominal-thickness groups follow public section data. Reference JR impact 27 J / +20°C; sampling and exemptions follow the standard. Structural design determines member, stability and connection capacities.
05 / Inspection, Processing & Quality Checks
- Check the complete a×b×t geometry; similar kg/m does not establish equivalent section dimensions.
- Design must check eccentricity, net section and hole edge distances. After drilling, gross-section capacity alone is insufficient.
- Confirm strength for nominal leg thickness and delivery condition. JR does not replace J2 low-temperature requirements.
- Identify cutting, drilling and bundles by hand / drawing number for site assembly.
06 / Export Packaging for This Product
| Stage | Recommended Arrangement | Key Considerations |
|---|---|---|
| Section-Separated Bundles | Identify section designation, steel grade, length and heat number separately. | Keep different grades and delivery conditions in separate bundles. |
| Supports & Corner Protection | Protect flanges, leg edges and machined faces; support long sections at multiple points. | Prevent handling twist, local damage and permanent bending. |
| Loading Checks | Plan loading around cut length, bundle weight, forklift points and container-door clearance. | Assess container type and handling arrangements in advance for long or heavy loads. |
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.
