Product Overview
Our Q355 H-Beam is a high-strength, cost-effective, and versatile structural steel profile widely used across industrial, commercial, and infrastructure projects. As an upgraded material compared to Q235 and Q345, Q355 offers higher yield strength, improved toughness, and better load-bearing capacity, making it ideal for long-span and high-load engineering.
We supply hot-rolled and welded Q355 H-beams, available in a wide range of sizes and surface treatments. Whether for workshops, steel structure buildings, bridges, or machinery frameworks, Q355 provides an excellent balance of strength, stability, and economic performance.
Why Choose Q355 H-Beam? (Performance Advantages)
1. Superior Load-Bearing Efficiency
-
Section modulus is 10–20% higher than traditional I-beams of the same weight.
-
Higher yield strength (≥355 MPa) ensures excellent load resistance.
2. Significant Material Savings
-
Optimized H-shape design reduces steel usage by 10–30% in structural engineering.
-
Lightweight structure reduces foundation load and total construction cost.
3. Long Service Life
-
Q355 steel provides 25–40% longer lifespan compared to ordinary carbon steel.
-
Optional hot-dip galvanizing improves corrosion resistance for 30–50+ years.
4. High Structural Stability
-
Excellent plasticity and seismic performance
-
Suitable for earthquake zones and high-wind regions
5. Flexible Manufacturing Options
-
Available in:
-
Hot-rolled H-Beams (HW / HM / HN)
-
Welded H-Beams
-
-
Supports custom sizes and fabrication based on engineering requirements.

Product Categories
1. Hot-Rolled Q355 H-Beams
-
HW: Equal height and flange width-ideal for core columns
-
HM: Medium flange width-used for dynamic-load columns
-
HN: Narrow flange-used for beams, cranes, and bridges
-
2. Welded Q355 H-Beams
-
Custom-made for large spans and non-standard dimensions
-
Ideal when hot-rolled sizes do not meet project needs
-
Applications of Q355 H-Beam
Q355 H-beams are widely used in medium to large-scale engineering projects requiring high strength and reliability:
-
High-rise building frameworks
-
Industrial plants & workshops
-
Steel structure warehouses
-
Bridges (highway & railway girders)
-
Ports, terminals & logistics platforms
-
Machinery frames, cranes & lifting equipment
-
Shipbuilding and marine engineering
-
Structural supports for rail, metro & infrastructure
The excellent strength-to-weight ratio makes Q355 especially suitable for large-span, heavy-load, and seismic-resistant construction.
