H-section steel, also known as H-beam, is a type of structural steel with a cross-section shaped like the letter "H." It features equal thickness in both the web and flanges, providing balanced strength and stability.
Manufactured from rolled steel, H-beams are available in various sizes and grades to meet the demands of different projects. They are widely used in construction for supporting floors, roofs, and load-bearing frameworks, and are also essential in sectors like manufacturing, mining, and infrastructure development.
Thanks to their high load-bearing capacity, structural efficiency, and versatility, H-section beams offer clear advantages over other types of steel profiles, making them a preferred choice in both civil and industrial applications.
Union Steel Industry Co., Ltd is professional h-section steel manufacturer, for more details, please contact:sales@union-steels.com
Standard Sizes for H-Section Steel
For specific standards, H-beam steel includes the parameters:
H: height of the steel column
B: width of the steel flange
t1: thickness of the steel web
t2: thickness of the steel flange
L: length of the steel column
W: steel weight, calculated in Kg/m
