1. Product Definition
H-beam is an economic and high-efficiency profile with an H-shaped section, composed of vertical web and parallel flanges. The inner and outer sides of the flanges are parallel with right-angle ends, featuring optimized material distribution and high strength-to-weight ratio, making it a key material for modern steel structures.
2. Product Classification
By Flange Width (Application)
HW (Wide Flange H-Beam): Height ≈ flange width, evenly stressed, mainly used for columns, supports and steel piles.
HM (Medium Flange H-Beam): Aspect ratio 1.33–1.75, suitable for both beams and columns.
HN (Narrow Flange H-Beam): Aspect ratio ≥2, strong bending resistance, mainly used for beams.
HT (Thin-Wall H-Beam): Lighter web and flanges, used for light workshops, curtain walls and purlins.
By Production Process
Hot-Rolled H-Beam: High-temperature rolling, uniform performance, high precision, standard specifications.
Welded H-Beam: Cut and welded from steel plates, customizable sizes for large-span and non-standard components.
3. Specification Representation
H (Height) × B (Flange Width) × t₁ (Web Thickness) × t₂ (Flange Thickness)Example: HW300×300×10×15
