What Is A36 100×100×6×8 Wide Flange Steel H Beam?
A36 100×100×6×8 Wide Flange Steel H Beam is a carbon structural steel section specified with ASTM A36 material requirements. It has a 100 mm section depth, 100 mm flange width, 6 mm web thickness and 8 mm flange thickness.
This hot rolled H section has a nominal theoretical weight of approximately 17.2 kg/m, making it suitable for small structural frames, equipment supports, secondary beams and fabricated steel components where the section satisfies engineering load requirements.


Gnee supplies ASTM A36 H beams, wide flange profiles and structural steel sections, with cutting, drilling, welding and surface treatment services available according to project drawings.

ASTM A36 H Beam Mechanical Properties
ASTM A36 is a commonly specified carbon structural steel grade for welded, bolted and other structural applications. Its mechanical requirements provide a basis for evaluating material suitability, but structural load capacity must also be checked against the actual section properties and project design.

Each ASTM A36 structural steel beam order can be specified with a mill test certificate under EN 10204 Type 3.1, subject to mill certification arrangements. The certificate should identify the heat number, chemical analysis, mechanical test results and applicable product standard.
ASTM A36 H Section Steel Chemical Composition
For ASTM A36 structural shapes, the chemical composition requirements differ from those for plates and bars. The following limits apply to the structural shapes category under ASTM A36/A36M-19.

Applications of A36 100×100 Wide Flange Beams
The 100×100×6×8 A36 H profile is generally considered for relatively small structural members. Its applications depend on loading conditions, connection design and the required structural stability.
- Equipment support frames: Fabricated supports for industrial equipment and machinery.
- Secondary steel structures: Small beams and framing members in workshops and industrial buildings.
- Platforms and walkways: Support members for platforms and maintenance access systems.
- Prefabricated steel assemblies: Cut, drilled and welded components prepared according to fabrication drawings.



A36 H Beam Cutting, Drilling and Fabrication Services
For steel structure procurement, buyers often require fabricated A36 H beams rather than full-length raw sections.
Gnee offers processing services for A36 wide flange beams and H profiles, including length cutting, hole drilling, welded connections and surface treatment. Fabrication dimensions, tolerances and inspection requirements are reviewed against the customer's drawings before production.
