A flange is a protruding rim or collar used to connect structural steel I-beams, providing secure attachment points for bolts or welding.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Width | 100-300 mm | |
| Thickness | 10-40 mm | |
| Hole Pattern | Standardized spacing per engineering drawings | |
| Surface Finish | Mill scale removed, Sa 2.5 blasted if coated | |
| Bolt Hole Diameter | 16-30 mm | |
| Flatness Tolerance | ±1.5 mm/m |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is used in the following industrial products
Hot-rolled structural steel beam with I-shaped cross-section for load-bearing frameworks.
The conical discharge section at the bottom of a hydrocyclone separator that collects and directs the denser underflow stream.
A refractory component that directs molten steel from the tundish into the mold while submerged below the metal surface.

The flange provides a reinforced connection point for joining I-beams securely, distributing loads and preventing structural failure at joints.
Yes, flanges are designed for both welding and bolting methods, with standardized hole patterns for bolt connections and prepared edges for welding.
Structural steel grades like ASTM A36 and A992 are most common, with alloy steels used for high-stress applications and coatings for corrosion protection.
