H‑Section Steel, also known as H‑beam, is an economic‑section structural steel with H‑shaped cross‑section. H‑Section Steel features wide thick flanges with parallel inner‑outer surfaces and excellent bending resistance. H‑Section Steel saves steel consumption compared with ordinary I‑beam, and it is the core load‑bearing profile for steel‑structure projects. H‑Section Steel includes Hot Rolled H‑Section Steel and Welded H‑Section Steel. Different‑process H‑Section Steel adapts to various load‑bearing conditions such as workshops, high‑rise buildings and bridges. H‑Section Steel owns uniform mechanical properties with excellent performance for welding, cutting and punching. H‑Section Steel has complete stock specifications, available in hot‑rolled black surface or hot‑dip galvanized anti‑corrosion finish. Hot Rolled H‑Section Steel is integrally hot‑rolled with low internal stress and high dimensional accuracy, suitable for mass‑volume projects. Welded H‑Section Steel is fabricated by steel plate assembling and welding, supporting non‑standard custom height and flange width to meet special dimensional requirements for projects. H‑Section Steel covers HW wide‑flange, HM medium‑flange, HN narrow‑flange series. H‑Section Steel can select proper series according to force‑bearing requirements for columns and main beams. Many large‑scale steel‑structure projects purchase both Hot Rolled H‑Section Steel and Welded H‑Section Steel to satisfy performance and dimensional requirements for H‑Section Steel on different parts. H‑Section Steel supports fixed‑length production, cutting, punching and beveling processing. Hot Rolled H‑Section Steel keeps mainstream sizes in stock, while Welded H‑Section Steel can be custom‑produced as required.
1. Material Grade

‑ Export Grades: A36, A992, SS400, S235JR, S355JR, St52‑3
2. Execution Standards
‑ GB/T 11263‑2017 Hot‑rolled H‑section steel and split T‑section steel (Chinese National Standard) ‑ YB/T 3301‑2005 Welded H‑section steel
‑ EN 10034 (European Standard), ASTM A6 (American Standard), JIS G3192 (Japanese Standard)
3. Specification Parameters
H‑Section Steel includes HW wide‑flange, HM medium‑flange, HN narrow‑flange series; height 100‑900mm, flange width 100‑400mm, web thickness 5‑21mm, flange thickness 7‑35mm.Hot Rolled H‑Section Steel covers full national‑standard sizes from HW100×100 to HN900×300, mainstream specifications kept in stock.Welded H‑Section Steel supports non‑standard customization, height, flange and plate thickness free from mill limitation, extra‑large cross‑section H‑Section Steel is available. Fixed lengths: 6m, 9m, 12m. Custom length, cutting, beveling and punching service are available.
4. Surface Treatment
‑ Hot‑rolled black: original rolled surface with low cost, for indoor workshops and main‑body steel‑structures. ‑ Hot‑dip galvanized: anti‑corrosion & rust‑proof, for outdoor, chemical and seaside high‑corrosion projects. ‑ H‑Section Steel supports painting, derusting, sandblasting, punching and beveling. Both Hot Rolled H‑Section Steel and Welded H‑Section Steel can be galvanized.
5. Main Applications
H‑Section Steel is widely applied in industrial‑workshop steel‑structures, high‑rise & super‑high‑rise building frames, steel columns, main roof beams, bridge components, equipment foundation supports, tower crane bases, prefabricated steel‑structures, municipal engineering and large‑scale warehouses. Hot Rolled H‑Section Steel is widely used for standard workshops, high‑rise steel columns, bridge main beams and other conventional large‑scale steel‑structure projects. Welded H‑Section Steel is used for non‑standard size, large‑cross‑section and special‑load steel‑structure projects. According to load and dimensional requirements, many large‑scale infrastructure projects adopt Hot Rolled H‑Section Steel and Welded H‑Section Steel separately to guarantee safe and stable performance of H‑Section Steel.
6. Packing, MOQ & Lead Time
‑ Packing: H‑Section Steel bundled with steel straps, separated by wooden blocks for protection, fit for sea container and full‑wagon railway transportation.
‑ MOQ: 5 tons minimum order quantity; mixed‑batch order for Hot Rolled H‑Section Steel and Welded H‑Section Steel is supported.
‑ Lead Time: 7‑12 days for stock Hot Rolled H‑Section Steel; 20‑30 days for customized Welded H‑Section Steel. Mill test certificate available. Third‑party inspection such as SGS/BV is acceptable. Support FOB, CIF, DAP trade terms.
7. Product Advantages
H‑Section Steel owns reasonable economic cross‑section, strong bending resistance and light self‑weight, effectively saving steel consumption.
Hot Rolled H‑Section Steel is integrally rolled with low internal stress, high dimensional accuracy, fast delivery and sufficient spot inventory.
Welded H‑Section Steel offers flexible dimensions, supports non‑standard large‑cross‑section customization for special‑engineering demands.
H‑Section Steel has good welding performance, third‑party inspection acceptable, complete quality documents can be provided.
