Stable structure and excellent carrying capacity
The H-shaped cross-section design of carbon steel H-shaped steel is exquisite. Its flange is wide and parallel, and its web thickness is reasonable, giving the steel excellent bending and compressive resistance. When subjected to transverse or vertical loads, it can effectively disperse stress and reduce deformation risk. For example, in the frame structure of large commercial buildings, carbon steel H-shaped steel, as the main load-bearing columns and beams, can easily carry huge roof and floor weights, ensuring that the building is stable and safe during long-term use. Compared with traditional I-shaped steel, the cross-sectional modulus of carbon steel H-shaped steel is larger at the same weight and has a load-bearing capacity of 10%-15%, which can meet the strength requirements of the structure in a more efficient manner.
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.
High strength and high load bearing
Stainless steel H steel has extremely high structural strength. Compared with ordinary I-shaped steel, its cross-sectional modulus is larger under the same load conditions, which can save 10%-15% of metal materials. In the beam and column structure of a building, it can easily withstand huge pressure and bending moments to ensure the stability of the building structure. In the framework construction of large commercial buildings, stainless steel H-steel, as the main load-bearing component, provides solid support for the entire building.
