H‑Shaped Steel is an economical load‑bearing structural steel with H‑shaped cross‑section. Both inner and outer sides of flanges are parallel, composed of web and upper‑lower flanges. H‑Shaped Steel features reasonable section stress distribution, excellent bending & compression resistance and good welding & fabrication performance. It serves as core load‑bearing profile for steel‑structure workshops, high‑rise buildings, bridge projects and equipment base constructions. H‑Shaped Steel mainly includes Hot‑Rolled H‑Shaped Steel and Welded H‑Shaped Steel. Different types of H‑Shaped Steel adapt to ordinary buildings, heavy‑duty frames, long‑span steel structures, low‑temperature & corrosive working conditions. H‑Shaped Steel has complete specification range including HW wide‑flange, HM medium‑flange, HN narrow‑flange series, sufficient stock and customized production available. Hot‑Rolled H‑Shaped Steel is integrally hot‑rolled from steel billets with uniform metallographic structure, high dimensional accuracy and low internal stress. It delivers stable comprehensive mechanical properties and favorable cost‑performance, widely used for factory steel columns, main frame beams and multi‑story building main structures. Made by cutting and assembling steel plates, Welded H‑Shaped Steel allows flexible customization of height, flange width, web & flange thickness without rolling mill restrictions, ideal for over‑size and special‑dimension heavy‑duty non‑standard components. H‑Shaped Steel can be supplied in black finish, shot‑blasted, painted or hot‑dip galvanized to meet indoor and outdoor anti‑corrosion requirements. Hot‑Rolled H‑Shaped Steel keeps mainstream specifications in stock with short and stable lead‑time. Welded H‑Shaped Steel supports drawing‑based custom processing including cutting, drilling and bevel prefabrication. Industrial workshops, high‑rise buildings, bridges, petrochemical equipment and rail‑transit steel‑structure projects select Hot‑Rolled H‑Shaped Steel and Welded H‑Shaped Steel according to load conditions, giving full play to H‑Shaped Steel’s advantages of high section efficiency, light self‑weight and strong load‑bearing capacity, ensuring overall safety and reliability of steel structures. H‑Shaped Steel covers multiple carbon steel and low‑alloy high‑strength grades for civil buildings and key large‑scale projects.
1. Material Grade
‑ Domestic Grades: Q235B, Q235C, Q235D, Q355B, Q355C, Q355D, Q355E, Q420B
‑ Export Grades: S235JR, S275JR, S355JR, S355J0, A36, A572Gr50, SS400
2. Execution Standards
‑ GB/T 11263‑2024 Hot‑rolled H and cut T section steel (Latest Chinese National Standard)
‑ GB/T 50661 Welding specification for steel structures (for welded H‑shaped steel)
‑ EN 10025 (European Standard), ASTM A6/A572 (American Standard), JIS G3101 (Japanese Standard), meeting acceptance standards of domestic and overseas projects
3. Specification Parameters
Conventional hot‑rolled sizes of H‑Shaped Steel: HW100×100‑HW400×400; HM150×100‑HM600×300; HN200×100‑HN900×300. Common delivery lengths of H‑Shaped Steel: 6m, 9m, 12m, fixed‑length cutting available. Designation format: H×B×t1×t2（Height × Flange Width × Web Thickness × Flange Thickness）.Hot‑Rolled H‑Shaped Steel fully complies with national standard with strictly controlled dimensional tolerance and good surface quality, suitable for mass‑purchase of standardized steel‑structure projects.Welded H‑Shaped Steel customizable section height:200‑1500mm, flange width:100‑600mm; web and flange thickness optional, not limited by hot‑roll sizes. Surface options: black finish, rust‑removal painting, epoxy zinc‑rich coating, hot‑dip galvanizing; pre‑processing such as cutting, drilling and beveling available. Non‑standard H‑Shaped Steel can be produced per drawings.
4. Classification & Surface Treatment
‑ Hot‑Rolled H‑Shaped Steel: integrally hot‑rolled from billets. HW wide‑flange for steel columns; HM medium‑flange for beam‑column members; HN narrow‑flange for beams. Low internal stress and good weldability, fit for standardized mass‑volume projects. ‑ Welded H‑Shaped Steel: fabricated by plate cutting, assembling and submerged‑arc welding. Flexible for over‑size and non‑standard cross‑sections, for heavy‑duty long‑span special steel‑structure components. ‑ Surface treatment: black as‑rolled; shot blasting; anti‑rust paint / epoxy paint coating; hot‑dip galvanizing anti‑corrosion. End‑face processing available for H‑Shaped Steel. Both Hot‑Rolled H‑Shaped Steel and Welded H‑Shaped Steel support customized anti‑corrosion processes.
5. Main Applications
H‑Shaped Steel is widely used for beam‑column members of steel‑structure workshops, portal frames, high‑rise building frames, prefabricated steel structures, highway & railway bridges, equipment support bases, petrochemical plants, wind‑power supports, storage racks, rail transit, port engineering and machinery equipment. Hot‑Rolled H‑Shaped Steel is preferred for standardized workshops, multi‑story buildings and common beam‑column components for large‑volume procurement. Welded H‑Shaped Steel is applied for heavy‑duty long‑span frames, non‑standard equipment bases, special‑load steel structures and over‑size cross‑section members. Most large‑scale projects adopt Hot‑Rolled H‑Shaped Steel and Welded H‑Shaped Steel according to load, span and dimensional constraints, utilizing excellent section performance of H‑Shaped Steel to reduce self‑weight, save steel consumption and improve structural stability.
6. Packing, MOQ & Lead Time
‑ Packing: H‑Shaped Steel bundled and fastened with steel straps, end‑part protection, suitable for container, bulk vessel, railway and truck long‑distance transportation.
‑ MOQ: 5 tons minimum order quantity, mixed‑batch order for Hot‑Rolled H‑Shaped Steel and Welded H‑Shaped Steel supported.
‑ Lead Time: 7‑12 days for in‑stock Hot‑Rolled H‑Shaped Steel; 18‑28 days for drawing‑based customized Welded H‑Shaped Steel.
Mill test certificates and mechanical performance reports available. SGS / BV third‑party inspection acceptable. Support FOB, CIF, DAP and other foreign‑trade terms.
7. Product Advantages
H‑Shaped Steel owns reasonable cross‑section stress distribution, strong bidirectional bending & compression resistance, higher material utilization than I‑beam, reducing structural self‑weight and foundation cost.
Hot‑Rolled H‑Shaped Steel features integrated rolling, uniform microstructure, high dimensional accuracy, sufficient stock and fast delivery. Easy for welding and cutting, ideal for large‑scale steel‑structure projects.
Welded H‑Shaped Steel offers flexible cross‑section independent of hot‑roll specification limits, capable for extra‑large non‑standard sections for heavy‑duty special‑condition projects.
H‑Shaped Steel provides abundant material grade options and multiple anti‑corrosion treatments. Complete quality documents are provided and third‑party inspection is supported for worry‑free procurement and acceptance.
