Galvanized H-steel
Excellent corrosion resistance
The most significant advantage of galvanized H-steel is its excellent corrosion resistance. Whether it is using the hot-dip galvanizing process to immerse H steel in a melted zinc liquid at about 500℃, the zinc layer firmly adheres to the surface of the steel, forming a protective layer with a uniform thickness of up to 30-50μm; or using electrogalvanizing (cold galvanizing) technology to deposit a uniform and dense zinc layer on the surface of the steel using the electrolytic principle, it can effectively resist the erosion of various strong acids and alkali mists and other strong corrosion environments. In humid coastal construction projects, the structural frame made of galvanized H-steel can resist salt corrosion caused by sea breeze for a long time, ensure the safety and stability of the building structure, and greatly extend the service life.

| Category | Details |
| Height (H) | The range covers a wide range, with common specifications ranging from 100mm to 900mm, which can meet the requirements of steel heights for projects of different sizes and types. The beam structure of small buildings may use galvanized H steel with a height of 100mm - 300mm, while the load-bearing columns of large industrial factories and high-rise buildings require products with a height of more than 500mm |
| Width (B) | Usually in the range of 50mm - 400mm, the height and width of different series of galvanized H steel have a specific proportional relationship. The narrow flange HN series has a relatively narrow width and is suitable for general bending components; the wide flange HW series has a relatively large width and is mainly used for structures that withstand greater pressure and bending moments, such as foundation columns in heavy buildings |
| Web thickness (t1) | It is generally located in 4mm - 16mm, and the web is a key part of bearing shear force, and its thickness is adjusted according to the requirements of the load-bearing capacity of the steel. Galvanized H steel that withstands heavy loads will increase the web thickness accordingly to ensure structural safety |
| Flange thickness (t2) | In the range of 5mm - 25mm, the flange mainly bears bending moments, which has a significant impact on the bending performance of the steel. By rationally designing the flange thickness, the mechanical properties of galvanized H-steel can be optimized to better adapt to different stress conditions |
| Length | The standard length is generally 6m, 9m, 12m. Non-standard lengths can also be customized according to customer actual needs to reduce the splicing workload at the construction site, improve construction efficiency, and reduce construction costs |
| Theoretical weight | There are many differences due to different specifications. For example, the theoretical weight of common HN200×100 galvanized H steel is about 26.66kg/m, while the theoretical weight of HW400×400 galvanized H steel can reach 172kg/m, etc. Accurate theoretical weight data facilitates users to conduct weight estimation and cost accounting during design and procurement |
| Galvanized layer thickness | The thickness of the hot-dip galvanized layer is uniform, generally 30 - 50 μm, and the thickness of the electro-plating galvanized layer is relatively thin, usually 5 - 15 μm. Different application scenarios and corrosion environments can choose products with suitable galvanized layer thickness to ensure the best corrosion resistance |
| Material Brand | Commonly used carbon steel materials such as Q235 and Q345. Q235 has good plasticity, toughness and welding properties, and is suitable for general building structures and projects; Q345 has higher strength and is widely used in scenarios with high requirements for structural bearing capacity |
