Steel I-beam Specifications – Product Details

Steel I-beams, also known as H-beams or universal beams, are widely used in construction and structural engineering due to their high strength-to-weight ratio and versatility. Below are the detailed specifications and features of our high-quality steel I-beams:

1. Material and Grade

• Material: High-strength low-alloy steel (HSLA), carbon steel, or stainless steel.

• Grades: ASTM A36, A572, A992 (common grades for structural applications).

• Yield Strength: 36,000 psi (ASTM A36) to 50,000 psi (ASTM A572).

• Tensile Strength: 58,000 psi to 65,000 psi.

• 2. Dimensions and Sizes

• Depth (Height): 3 inches to 24 inches (76.2 mm to 609.6 mm).

• Flange Width: 2 inches to 12 inches (50.8 mm to 304.8 mm).

• Web Thickness: 0.2 inches to 1 inch (5.08 mm to 25.4 mm).

• Flange Thickness: 0.3 inches to 1.5 inches (7.62 mm to 38.1 mm).

• Length: Standard lengths of 20 ft, 30 ft, 40 ft (6 m, 9 m, 12 m), or custom lengths available.

3. Weight

• Weight per Foot: Ranges from 6 lbs/ft to 120 lbs/ft (9 kg/m to 178 kg/m).

• Weight Calculation Formula:
  Weight (lbs/ft) = (Depth (in) x Flange Width (in) x 0.45) - (Web Thickness (in) x 0.3).

4. Surface Finish

• Hot-Rolled: Standard finish for structural applications.

• Galvanized: Zinc-coated for corrosion resistance in outdoor or harsh environments.

• Painted: Custom paint finishes available for aesthetic or protective purposes.

5. Tolerances

• Depth Tolerance: ±1/8 inch (±3.175 mm).

• Flange Width Tolerance: ±1/16 inch (±1.5875 mm).

• Straightness Tolerance: 1/8 inch per 10 ft (3.175 mm per 3 m).

6. Applications

• Construction: Used in building frames, bridges, and infrastructure projects.

• Industrial: Ideal for manufacturing machinery, equipment, and storage systems.

• Residential: Commonly used in house framing, garages, and roofing.

• Transportation: Suitable for trailer frames, rail tracks, and vehicle chassis.

7. Standards and Certifications

• ASTM Standards: ASTM A36, A572, A992.

• EN Standards: EN 10025 (European standards for structural steel).

• ISO Certification: ISO 9001 for quality management systems.
