High-Strength Low-Alloy H-Beam Q420C/Q460D for Bridge Construction
Production technology
H-beam steel, also known as H-section steel, is a structural steel with an "H"-shaped cross-section, consisting of two parallel flanges and a central web. It offers excellent mechanical properties, including high bending and compressive strength, making it widely used in construction, bridges, and machinery manufacturing. H-beams can be produced through hot rolling or welding and are classified into wide flange (HW), medium flange (HM), and narrow flange (HN) types based on flange width.
Specifications of H-beam steel
H-beam steel is available in a wide range of sizes and dimensions, allowing for flexibility in design and construction. The specific sizes and dimensions of H-beam steel can vary depending on regional standards and manufacturer specifications. However, here are some common H-beam steel sizes and dimensions:
Height (H): The height of an H-beam steel refers to the vertical distance between the top and bottom flanges. Millimeters (mm) or inches (in) are commonly used measurement units.
Flange Width (B): The flange width of an H-beam steel refers to the horizontal width of each flange. Millimeters (mm) or inches (in) are commonly used measurement units..
Web Thickness (t1): The web thickness of an H-beam steel refers to the thickness of the vertical web connecting the two flanges. Millimeters (mm) or inches (in) are commonly used measurement units.
Flange Thickness (t2): The flange thickness of an H-beam steel refers to the thickness of each flange. Millimeters (mm) or inches (in) are commonly used measurement units.
For example, a common H-beam steel size might be denoted as “H-beam 200x200x8x12,” where:

Applications of Steel H Beams
(1) Construction:H-shaped steel beams are often used in construction for structural frames, roof beams, staircase frames, etc., with strong bearing capacity and good stability. It supports large-span structures, making the building structure more solid and safe.
(2) Bridges:In bridge engineering, H-shaped steel beams are used for main beams, bridge towers and abutments, with high bending stiffness and light weight. Its high bearing capacity and stiffness ensure the safety and stability of the bridge structure.
(3) Infrastructure: H-shaped steel beams are often used in the brackets and frame structures of machinery manufacturing equipment, as well as the main beams and secondary beams of industrial plants. It is also suitable for manufacturing engineering machinery such as lifting machinery and trucks, and as equipment brackets to support and fix various equipment
