H-Beam (Standard Structural Steel)
H-Beam steel (H-beam) is Hot rolled steel It has a cross-section shaped like the letter H, with the following key characteristics: “"The width of the flange will be equal to or approximately equal to the height of the web."” (e.g., sizes 100×100, 150×150) resulting in balanced engineering properties, allowing for good torsional and compressive strength in all directions.
Our products are made from high-quality steel and are certified to meet standards. TIS 1227-2015 There are different grades to choose from. SS400 (For general structural work) and SM520 (For high-rise buildings requiring extra tensile strength)
Key features of AY Contento H-Beam steel.
- Perfect for Columns: Its square cross-sectional dimensions result in a balanced radius of gyration, making it ideal for building columns that must support high compressive loads.
- Parallel Flanges: The upper and lower wings have the same thickness and are parallel along their entire length, making them easy to connect and assemble (unlike I-beams which have sloped wings).
- Clean & Modern Look: The smooth, sleek steel surface and airy, modern structure are popular in architectural designs that aim to showcase the structural elements.
Applications
- Building columns (Main Column): Residential houses, factories, warehouses, commercial buildings
- Machine weight-bearing structure: Machine base, foundation
- Pile driving work: Used as steel piles for projects requiring speed and low vibration.
- Beam work: Used as main beams or secondary beams in buildings with wide column spans.

Frequently Asked Questions (FAQ)
- H-Beam: Wide, parallel, and evenly thick wings are suitable for... Columns and beams
- I-Beam: Narrower wings, sloping (thick at the base, thin at the tip), rounded edges, suitable for... Crane rails (Crane Runway) Because it can withstand pressure on the wings better at specific points.
Yes, and that's great! Using a steel structure allows for construction up to twice as fast as concrete systems, results in a cleaner construction site, and provides increased usable space because the columns are smaller than concrete columns while maintaining the same strength.
