Tapered Flange Channels - FAQs

Usually made from hot-rolled steel, a tapered flange channels are a common structural steel profile with a wide flat surface (web) and flanges at right angles to the web on either side of the web, forming a C-shape. The thickness of the flanges reduces from the web to the ends. The outer edges of tapered flange channels are sharply angled, while the inner surface has radius corners.

The flanges of a tapered flange channels taper in thickness from the web (the wide, flat part of the channel) to their ends, forming right angles on the outside and radius angles on the inside. The flanges of a parallel flange channel are the same thickness from the web to their ends, creating right angles on the outside and inside of the channel.

Tapered flange channels and I-beams are the two steel profile shapes with tapered flanges.

Tapered flange channels are used in a wide range of construction and other applications. They are commonly used for beams, columns, lightweight purlins, and other structural elements in multi-storey and industrial structures and bridges. They are also used in mining infrastructure, and in the manufacturing, transport, and storage industries.
