I. Product Name
H-Section Steel
II. Product Introduction
H-section steel is an economical and efficient section profile with optimized cross-sectional area distribution and a reasonable strength-to-weight ratio, named for its cross-section resembling the English letter "H". Composed of a web and upper and lower flanges, this product has a regular cross-sectional shape and uniform force bearing. Compared with ordinary I-beams and channel steels, it has significant advantages such as strong bending resistance, simple construction, cost saving and light structural weight. It is widely used in various fields such as industrial buildings, steel structure workshops, bridges, supports, machinery manufacturing, storage shelves, and high-rise buildings, and is one of the core profiles in modern steel structure projects.
III. Implementation Standards
National Standard (China): GB/T 11263-2017
American Standard: ASTM A6/A6M
European Standard: EN 10034 / HEA, HEB, HEM Series
Japanese Standard: JIS G3192
Customized standards can be provided according to customer requirements
IV. Production Process
Hot-Rolled H-Section Steel: Using high-quality continuous casting billets as raw materials, it is rolled by professional rolling mills after high-temperature heating. The product has a dense structure, uniform grains, stable and reliable mechanical properties, and strong bearing capacity. It is suitable for large-scale steel structure projects, bridge construction and other scenarios with high requirements for steel performance.
Welded H-Section Steel: Selected standard-compliant steel plates are accurately assembled by CNC equipment, welded by automatic submerged arc welding, and straightened by a straightening machine. It can be flexibly customized into non-standard specifications according to actual customer needs, adapting to special working conditions, with high cost performance, and is widely used in small and medium-sized steel structure projects.

VI. Product Specifications
Height: 100mm – 900mm
Flange Width: 50mm – 400mm
Web Thickness: 4.5mm – 30mm
Flange Thickness: 6mm – 40mm
Length: 6m, 9m, 12m (customizable cutting available)
VII. Product Performance
Excellent cross-sectional mechanical properties, high bending, compression and torsion strength, uniform force bearing, which can effectively bear various loads and ensure structural safety and stability.
Good structural stability, which can significantly reduce the amount of steel used compared with traditional profiles, reduce engineering costs, and at the same time reduce the structural dead weight, improving the overall economy of the project.
Excellent welding and drilling performance, which can be directly subjected to on-site welding, drilling and other processing operations, making the construction convenient and efficient and shortening the construction period.
Smooth surface and high dimensional accuracy without obvious defects, which is convenient for subsequent anti-corrosion coating and rust prevention treatment, extending the service life of the product.
VIII. Application Fields
Steel structure workshops, factories and warehouses
High-rise buildings and residential steel structures
Bridges, tunnels and tower structures
Mechanical bases and equipment supports
Ports, terminals, logistics shelves and vehicle frames
IX. Packaging and Delivery
Packaging: Bundled with high-strength steel strips, with reasonable weight per bundle for easy loading, unloading and transportation. Additional moisture-proof film and waterproof packaging can be added according to different transportation requirements such as sea transportation to prevent the product from being damp and rusted.
Delivery Status: Various delivery forms such as hot-rolled status, pickled status and primer-sprayed status can be provided according to customer needs to meet the direct use requirements of different construction scenarios.
Delivery Cycle: Sufficient inventory for conventional specifications, which can be shipped within 5–7 days after ordering; the cycle for non-standard specifications can be reasonably adjusted according to the production difficulty to ensure on-time delivery.
Transportation Method: Road transportation is mainly adopted for domestic transportation; container or bulk carrier is used for foreign trade export, with full logistics tracking to ensure the safe delivery of products.
