H‑Beam is 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‑Beam features reasonable mechanical distribution of cross‑section, outstanding bending & compression resistance and excellent performance in welding, punching and cutting. It has light self‑weight and high bearing capacity. It is an indispensable core structural steel for steel‑structure workshops, high‑rise buildings, bridge engineering and equipment bases. H‑Beam is mainly divided into Hot‑Rolled H‑Beam and Welded H‑Beam. Different‑process H‑Beam adapts to ordinary workshop frames, high‑rise load‑bearing columns, long‑span bridges, heavy‑duty equipment supports and other working conditions. With complete specifications and sufficient stock, H‑Beam supports deep‑processing customization including fixed‑length cutting, beveling, shot blasting, painting, galvanizing and punching. Manufactured by integral high‑temperature hot rolling from steel billet with uniform stable metallographic structure and low internal stress,Hot‑Rolled H‑Beam delivers prominent cost‑effectiveness. It is the most versatile and widely‑used H‑Beam for steel‑structure workshop beams & columns, building frames, ordinary supports and municipal engineering projects. Assembled and welded by steel plates, Welded H‑Beam has flexible specifications unrestricted by rolling mill, capable of producing extra‑large‑section and non‑standard‑size H‑Beam. It is largely applied in long‑span steel structures, heavy‑duty equipment bases, high‑rise building load‑bearing components and large‑scale venues. Conventional series of H‑Beam include HW, HM, HN; height 100‑900 mm, flange width 50‑400 mm, web & flange thickness 5‑28 mm, standard length 6‑12 m. Main grades include Q235B, Q355B, Q355C, Q355D; export grades A36, S235JR, S355JR, SS400. Delivery condition is hot‑rolled or welded finish. Shot blasting, anti‑rust painting and hot‑dip galvanizing anti‑corrosion treatment are optional. Inspection covers appearance, dimensional tolerance and weld flaw detection. All H‑Beam products go through full inspections for dimensional tolerance, mechanical property and weld quality. Steel‑structure, construction‑engineering and equipment‑manufacturing enterprises can select Hot‑Rolled H‑Beam and Welded H‑Beam according to load, span and working‑condition requirements, giving full play to advantages of reasonable cross‑section, high bearing capacity and convenient construction of H‑Beam to guarantee long‑term stable and safe operation of the whole steel‑structure system.

‑ Original mill test certificates available, SGS/BV third‑party inspection and weld‑flaw‑detection acceptance acceptable.
3. Specification Parameters
H‑Beam‑Hot‑Rolled H‑Beam: HW/HM/HN series; height 100‑900 mm; length 6‑12 m; hot‑rolled finish; for workshop beams‑columns and ordinary building steel structures;H‑Beam‑Welded H‑Beam: non‑standard custom section; height 200‑1500 mm; length 6‑15 m; plate‑assembled welded finish; for long‑span structures, heavy‑duty equipment bases and large‑scale venues; Fixed‑length cutting, beveling, punching, shot blasting, painting and hot‑dip galvanizing deep‑processing are supported.Hot‑Rolled H‑Beam is well‑stocked with uniform structure and short delivery cycle for mass‑supply workshop and municipal steel‑structure projects;Welded H‑Beam features flexible specifications and customizable extra‑large non‑standard sections, preferred material for long‑span heavy‑duty steel‑structure engineering projects.
4. Classification & Surface Treatment
- Hot‑Rolled H‑Beam: integrally hot‑rolled from steel billet, balanced comprehensive mechanical performance, widely used for steel‑structure workshop beams‑columns, building frames and support components.
‑ Welded H‑Beam: fabricated by cutting & welding steel plates, mainly for extra‑large non‑standard components, heavy‑duty bases, long‑span venues and high‑rise load‑bearing structures.
‑ Delivery state: hot‑rolled / welded finish; surface options: black finish, shot‑blast rust removal, anti‑rust paint, hot‑dip galvanizing;
‑ Both Hot‑Rolled H‑Beam and Welded H‑Beam support customization of fixed length, punching and special anti‑corrosion treatment according to customer drawings and load parameters.
5. Main Applications
H‑Beam is core load‑bearing section steel for modern steel‑structure engineering, widely used in steel‑structure industrial workshops, high‑rise building frames, large‑span venues, bridge components, equipment base supports, storage racks, municipal engineering and offshore‑platform supports. Hot‑Rolled H‑Beam features high cost‑performance and stable supply. It is the most‑widely‑used H‑Beam for workshop steel‑structure and ordinary‑building supporting projects for conventional beam‑column load‑bearing members. Welded H‑Beam delivers flexible cross‑section dimensions, suitable for rigorous working conditions of extra‑large span and heavy‑duty load, improving overall bearing capacity of steel structures, largely adopted in key large‑scale public‑building and heavy‑equipment supporting projects. Steel‑structure processors and construction‑engineering enterprises can select grades accurately according to load‑span parameters, relying on complete‑grade, easy‑processing and stable mass‑supply advantages of H‑Beam to guarantee quality & safety of steel‑structure projects.
6. Packing, MOQ & Lead Time
- Packing:H‑Beam bundled & reinforced with steel straps, marked with grade, size and heat number at ends, suitable for land transportation and container sea shipment.
‑ MOQ: 5 tons minimum order quantity, mixed‑batch ordering of Hot‑Rolled H‑Beam and Welded H‑Beam supported, small‑batch sample orders and large‑scale engineering orders acceptable.
‑ Lead Time: 5‑7 days for regular in‑stock specifications; 15‑25 days for non‑standard Welded H‑Beam and anti‑corrosion deep‑processing orders. Full‑set mill test certificates and NDT reports are provided, third‑party inspection supported, applicable to FOB, CIF, DAP and other foreign‑trade terms.
7. Product Advantages
H‑Beam adopts scientifically‑rational cross‑section mechanical layout with strong bending‑compression resistance, saving steel consumption and reducing overall structural self‑weight compared with traditional I‑beam;
2. Hot‑Rolled H‑Beam is integrally hot‑rolled with low internal stress and good welding‑punching processing performance, economical procurement cost for large‑volume workshop and municipal steel‑structure projects;
3. Welded H‑Beam is free from rolling‑mill limitation on dimensions, capable of custom‑making extra‑large and non‑standard cross‑sections to satisfy high‑end steel‑structure‑equipment requirements for long‑span & heavy‑duty load;
4.H‑Beam features controllable dimensional tolerance and traceable material quality, easy acceptance for domestic and overseas construction & bridge projects and stable large‑volume supply capacity.
