H-beam steel, also known as wide flange beam or W-beam, is a high-efficiency structural steel profile characterized by its distinctive H-shaped cross-section. This design optimizes the distribution of sectional area, resulting in an exceptional strength-to-weight ratio that makes it a cost-effective choice for various engineering applications.
The profile consists of two main components: the web (vertical element) and the flanges (horizontal elements). The flanges are typically wider than the web, providing superior resistance to bending forces in both the strong and weak axes. This orthogonal arrangement of elements contributes to the beam’s excellent performance in all loading directions.
Key features of H-beam steel include:
H-beam steel is often referred to by several names in the industry, including:
The standardized dimensions and properties of H-beam steel are typically specified by international standards such as ASTM A992/A992M or EN 10025, ensuring consistency and reliability in structural design and fabrication processes.
H-beam steel, a crucial structural element in construction and engineering, is classified into several categories based on various criteria:
(1) Flange Width Classification:
• Wide Flange: Flange width (B) ≥ Web height (H)
• Medium Flange: Flange width (B) ≥ Web height (H)
• Narrow Flange: Flange width (B) ≈ 1/2 Web height (H)
(2) Functional Classification:
• Beam H-sections
• Column H-sections
• Pile H-sections
• Extra-thick flange H-sections
Parallel leg channel steel and parallel flange T-shaped steel are sometimes included in the H-beam family. Typically, narrow flange H-beams are utilized as beams, while wide flange H-beams serve as columns.
(3) Manufacturing Method:
• Welded H-beams: Fabricated by welding separate plates
• Rolled H-beams: Produced through hot rolling process
(4) Size Classification:
• Large: Web height (h) > 700mm
• Medium: Web height (h) = 300-700mm
• Small: Web height (h) < 300mm
As of late 1990, the world’s largest H-beam featured a web height of 1200mm and a flange width of 530mm, showcasing the advancement in manufacturing capabilities.
