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:
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.
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).
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.
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).
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.
ASTM Standards: ASTM A36, A572, A992.
EN Standards: EN 10025 (European standards for structural steel).
ISO Certification: ISO 9001 for quality management systems.
