STEEL PRODUCT
BAOJIANG supplies hot rolled H sections in Q235B (GB/T 700), Q355B (GB/T 1591) and S235JR (EN 10025-2), with a published section height range of 100-900 mm and standard 6 m and 12 m lengths. Sections are supplied to GB/T 11263. Quotation in USD on FOB or CIF terms.
| Grade | Standard that defines the grade | Minimum yield strength as specified |
|---|---|---|
| Q235B | GB/T 700 | 235 MPa for thickness up to 16 mm |
| Q355B | GB/T 1591 | 355 MPa for thickness up to 16 mm |
| S235JR | EN 10025-2 | 235 MPa for thickness up to 16 mm |
Sections are supplied to GB/T 11263, which fixes the dimensions of the HW, HM and HN series. Thickness-dependent values are the values stated on the mill test certificate for your heat.
| Item | Published range | Confirmed |
|---|---|---|
| Section height | 100-900 mm | Per order confirmation |
| Flange width, web and flange thickness | – | Fixed by the section table in GB/T 11263; confirmed per order for the section you name |
| Length | 6 m / 12 m standard | Cut to order where the supplier can provide it |
| Surface | Mill finish | Priming or coating coordinated if required |
An H section is named by its height and flange width, for example 300×300 mm. Give us the section name your drawing uses and we will confirm the complete dimension set, the tolerance and the weight per metre before the order.
Send the section designation, grade and standard, length, quantity, destination port and document requirement. For example: H 300×300, Q355B to GB/T 1591, 12 m, 24 t, CIF Jebel Ali, MTC required. We confirm the available route, the length and packing method, and the quotation basis.
A designation such as 300×300 means a section 300 mm high with a 300 mm flange width. The web and flange thicknesses are fixed by the section table in GB/T 11263, so the height and width alone do not define the section – name the section exactly as your drawing does and we will confirm the full dimension set.
Q355B is specified at a minimum yield strength of 355 MPa (GB/T 1591) and Q235B at 235 MPa (GB/T 700), for thickness up to 16 mm. Q355B is used where the structure carries more load or where the same capacity is needed in a lighter section. The choice follows the design code and the drawing – tell us which standard governs and we will confirm.
6 m and 12 m are the standard lengths. Fixed-length cutting is coordinated where the supplier can provide it; tell us the cut length and the acceptable tolerance.
Fixed-length cutting and surface preparation can be coordinated where the supplier offers it. Drilling, welding and fabrication are normally carried out by your fabricator after delivery, to their own drawing. Tell us if you need a processed condition and we will confirm what can be arranged.
Packing method, bundle weights, lifting points, marks and dunnage are agreed per order against the container or breakbulk plan and the destination.
For many products the practical minimum is around one container (about 20-25 tons). Mixed containers and smaller trial quantities can be reviewed.
We will confirm availability, the packing method and the quotation basis.
