About products and suppliers:

An aluminium c channel track is a type of aluminium extrusion used for structural applications. The main characteristic of these aluminium c channels is two flanges that protrude from one side resembling the letter "C" if viewed from a cross-section.

What is an aluminium c channel used for?

Metal channels serve a variety of purposes across industrial, structural and architectural industries. These channels can be used for repair work on buildings, vehicles and machinery. As a lighter-weight material, aluminium channels are typically used in architectural projects. Like the "U" and "J" aluminium channels, aluminium c channels come in a variety of lengths and thicknesses. The most common being between .003” thick and .500” thick. An aluminium c channel track can be used for framing, decoration, trim, posts, railings and door tracks. The benefits associated with aluminium c channel tracks include lightweight strength, corrosion and rust resistance and the eco-friendly perk of being 100% recyclable.

How are aluminium c channels made?

Aluminium channels are the result of pressing round aluminium billets or logs through a channel-shaped die using a high-pressure ram. The two types of extrusion methods are referred to as direct and indirect. Direct extrusion keeps the die in place while a ram presses the billet through the hollow die. Indirect extrusion keeps the billet in place while a die is run along the length of the log. Both of these processes can be applied using hot extrusion, cold extrusion and warm extrusion. Hot extrusion takes place when the aluminium is heated between 800º and 1800º F, usually within a vacuum to prevent any oxidation. Cold extrusion can take place near or at room temperature while warm extrusion occurs after heating the billets to a temperature between 800º and 1800º F. The final step is to straighten the aluminium billet along a stretcher preparing them for shipping.
