A36 W4×13 Wide Flange H Beam Steel is a hot-rolled structural steel beam manufactured according to the ASTM A36 standard. It is widely used in construction and structural engineering due to its reliable strength, excellent weldability, and cost-effective performance.
The W4×13 H Beam belongs to the American wide flange beam (W-shape) series, featuring a cross-section similar to the letter "H". This structural design provides an optimized strength-to-weight ratio and excellent bending resistance in multiple directions, making it suitable for a wide range of load-bearing applications.
A36 W4×13 Wide Flange H Beam Steel
With a stable yield strength of minimum 250 MPa (36 ksi), ASTM A36 steel beams are commonly used in building frames, industrial structures, bridges, and machinery support systems. The W4×13 beam is especially suitable for medium-duty structural components where compact size and structural efficiency are required.

Advantages of Wide Flange H Beam
Wide flange H-beams are widely used in modern construction due to their structural and economic benefits.
High Structural Strength
Compared with traditional I-beams, H-beams provide a larger section modulus, improving load-bearing performance while reducing material consumption by up to 10–15%.
Excellent Structural Stability
The symmetrical cross-section design allows the beam to resist bending forces effectively in multiple directions, providing excellent stability in structural frameworks.
Lightweight Structural Design
Steel structures using H-beams are significantly lighter than reinforced concrete structures, which reduces foundation loads and overall construction costs.
Efficient Space Utilization
Because steel columns and beams require smaller cross-sections than concrete elements, they increase the usable floor area in buildings.
Easy Fabrication and Installation
H-beams are easy to cut, weld, drill, and assemble, which simplifies construction and reduces installation time.
Recyclable and Sustainable
Steel beams can be reused and recycled, making them an environmentally friendly construction material.
Applications of A36 W4×13 Wide Flange Beam
Due to its excellent structural performance, ASTM A36 W4×13 H Beam Steel is widely used in many industries.

What is A36 grade structural steel?
A36 is a standard structural steel grade, specifically defined by ASTM for carbon steel. It is typically available in hot-rolled form, although cold-rolled options exist for tighter tolerance needs. As a structural-grade material, it's used in everything from building frameworks and bridges to heavy equipment.
What does A36 stand for?
A36 is designated by its mechanical properties instead of its chemical properties. In the American Society for Testing Materials (ASTM) system, the A stands for ferrous metal, while the 36 refers to its minimum yield strength of 36,000 PSI.
What steel is stronger than A36?
A572 is a high-strength, low-alloy (HSLA) steel with a minimum yield strength of 50 ksi, while A36 has a minimum yield of 36 ksi. A572 contains strengthening alloys like manganese and phosphorus, making it stronger and more corrosion-resistant than A36.
What is the thickness of A36?
vailable Sizes in A36 Heavy Steel Plate
| THICKNESS | LENGTH | |
