Product type
I-beams, also known as H-beams or universal beams, are structural steel components characterized by their distinctive 'I' shape. They are made from high-strength steel, which provides excellent load-bearing capabilities while minimizing weight. The design of I-beams allows for efficient distribution of weight and stress, making them ideal for a variety of construction applications.
| Material | Structural steel, typically ASTM A992 or A572 |
| Standard sizes | Widths from 4 to 12 inches and lengths from 20 to 60 feet |
| Weight per foot | Ranges from 10 to 50 pounds per foot |
| Flange thickness | Typically between 0.25 to 0.75 inches |
| Web thickness | Typically between 0.20 to 0.50 inches |
When selecting I-beams, buyers should consider the specific load requirements and the span of the structure. It's important to specify the desired material grade, as well as any necessary certifications for structural integrity. Tolerances for dimensions and weight should also be discussed, along with the quantities needed for the project, to ensure accurate pricing and delivery timelines.

I-beams have a narrower flange compared to H-beams, which have wider flanges and are typically used for heavier loads.
I-beams are produced by rolling steel into the desired shape, followed by cutting to length and finishing processes.
The load capacity is influenced by the beam's dimensions, material grade, and the type of load applied (uniform or concentrated).
Yes, I-beams are versatile and can be used in both residential and commercial construction applications.
Common coatings include galvanized finishes for corrosion resistance and paint for aesthetic purposes.
Consult with a structural engineer to calculate the required size based on load, span, and other design factors.
