JIS SS400 Wide Flange H-Beam
Wide-flange H sections for columns, support frames and general structural fabrication selected by the project designer. The size table identifies actual depth, flange width, web and flange thickness so that buyers can compare drawings without relying on a nominal designation alone.
| Ordering item | Specification |
|---|---|
| Material / standard | JIS G3101 material / JIS G3192 section series |
| Product family | H Sections |
| Supply basis | Enquiry-based grade, dimensions, processing and quantity; availability, MOQ and delivery confirmed in the quotation. |
| Inspection documents | Request heat/batch records and EN 10204 3.1 or other documents where required; actual document scope must be confirmed. |
01 / Selection Advantages
- Published section dimensions and nominal mass support clear cutting and logistics schedules.
- Grade, cut length, holes and surface preparation can be reviewed as one fabrication enquiry.
- Bundle marks and length separation support traceability and efficient unloading.
02 / Specifications & Size Schedule
Use the following options to prepare a complete enquiry. The lists do not imply that every dimension combination is stocked or interchangeable with another standard. State the required tolerances and quantity for each line.
| Parameter | Enquiry requirement |
|---|---|
| Series | Selected JIS wide-flange series |
| Length / m | 6, 9, 12 or project cut lengths |
| Surface | As rolled; blasting, primer or galvanizing by separate agreement |
| Drawing information | State H × B × tw × tf, length, quantity, holes and end cuts |
| Design data | Request full section properties and verify structural design separately |
| Actual H / mm | B / mm | Web tw / mm | Flange tf / mm | Nominal kg/m |
|---|---|---|---|---|
| 100 | 100 | 6 | 8 | 16.9 |
| 125 | 125 | 6.5 | 9 | 23.6 |
| 150 | 150 | 7 | 10 | 31.1 |
| 175 | 175 | 7.5 | 11 | 40.4 |
| 200 | 200 | 8 | 12 | 49.9 |
| 250 | 250 | 9 | 14 | 71.8 |
| 300 | 300 | 10 | 15 | 93.0 |
03 / Chemical Composition
Composition is expressed in weight percent. Maximum and minimum limits refer to the listed grade/product reference; final acceptance follows the agreed standard edition and heat analysis.
| Element | Grade reference / wt.% |
|---|---|
| C | Not specified by JIS G3101 for SS400 |
| Si | Not specified |
| Mn | Not specified |
| P | ≤0.050 |
| S | ≤0.050 |
| Fe | Balance |
04 / Mechanical Properties & Technical Notes
| Applicable plate thickness | Min yield / MPa | Tensile / MPa | Elongation note |
|---|---|---|---|
| t ≤16 mm for listed sizes | 245 | 400–510 | Specimen/thickness dependent; e.g. No.1A 17% for 5 < t ≤16 mm |
Dimensions and masses are manufacturer-published section references, not a stock declaration. Actual rolling tolerances and radii affect delivered mass. SS400 does not automatically meet an EN grade, specified impact class or a project seismic requirement. Confirm the ordered standard edition and inspection records.
05 / Processing & Inspection
| Control point | What to agree or inspect |
|---|---|
| Incoming identity | Review section designation, heat/grade marks and certificates. |
| Geometry | Check H, B, web/flange thickness, length, camber and squareness. |
| Processing | Transfer piece/heat marks after cutting; review drilling and end-cut drawings. |
| Load design | Obtain engineer-approved section selection, connections and corrosion protection. |
Include additional tests, third-party inspection, marking transfer and processing requirements before order confirmation. Qida can coordinate the agreed inspection scope and supporting records; an online product guide is not a delivered-batch test certificate.
06 / Export Packaging & Transport
| Packing item | Practical requirement |
|---|---|
| Size segregation | Bundle sections by size/grade/length and transfer clear heat/order labels. |
| Protection | Use suitable spacers, strap guards and dry supports; separate finished faces. |
| Handling | Agree bundle weight, sling positions and access for the destination equipment. |
| Loading plan | Support long sections, distribute mass and secure against sliding and tipping. |
Agree destination port, Incoterms rule and named place, package mass, unloading equipment and required shipping documents. Container capacity depends on payload limits, route and load distribution. For regulated solid-wood packaging, confirm the applicable ISPM 15 treatment and marking requirements.
07 / Qida Procurement Support
| Order stage | Our coordination | Buyer benefit |
|---|---|---|
| Specification review | Review material, dimensions, units, drawings and destination requirements. | A clear line-by-line enquiry helps reduce omissions and incompatible substitutions. |
| Processing plan | Confirm cutting, finishing, inspection and identification items in writing. | The buyer can assess scope and acceptance before production or sourcing proceeds. |
| Packing & dispatch | Coordinate labels, packing list, suitable protection and shipping-document requirements. | Piece count and heat/lot correspondence can be checked at agreed milestones. |
| After-sales follow-up | Review order references, arrival photos and inspection records for reported issues. | A documented issue description supports a specific response and follow-up. |
08 / Request a Detailed Quotation
Send the standard and edition, grade, size schedule, quantity per size, material condition, finish, processing drawings, tests/documents, packing requirements and destination port. Include maximum piece or package weight and any project approval requirements. Pricing, minimum quantity and lead time will be confirmed against the actual requirement.
