Channel steel is a common construction component and typically made from hot-rolled steel with a wide, flat surface and flanges at right angles on either side. The outer edge is sharply angled while the inner surface contains radius corners. The channel provides stability while the wide, flat surface is ideal for affixing items and providing support. In its largest form, channel steel is used to support bridge decks and other very large object and has the ability to absorb flex and other forces that might damage more rigid I-beams and H-beams.
Various Sizes and Uses
Because it comes in a variety of sizes, the steel components are used widely in industrial use. One of the most common is for frame supports in the automotive industry. Sometime, the pieces are welded together to create a box-like structure, and they can be welded with the wide, flat surfaces joined to create an I-beam. The versatility of the channel structure enables industries to be more creative that with more rigid I-beams and other steel components. The channel also makes it relatively lightweight while still ensuring strength and rigidity for equipment frames and other industrial applications.
The channel steel also is beneficial for outdoor use, particularly when made with additional amounts of copper, nickel or chromium that makes the steel more resistant to corrosion. The combination of corrosion resistance and light weight make it a great option for light poles, towers, construction equipment, and other items that are exposed to weather.
