Steel channels can be utilized in both metal and wood-framed buildings to provide strong frames for windows and doors. The channel is made up of four parts with miter joints on each end, and it glides over the wall in the window or door opening. This creates a flat surface in the opening on which a door or window can be mounted and is far more secure than wood frames. Commercial fire doors, as well as sub-grade basement doors, are frequently framed with steel channels.
Steel channels can be used to strengthen the rigidity and strength of hardwood beams in a wood-framed building when extra strength is required. Wood beams can be placed inside a large steel channel for added strength while still allowing joists and other components to be easily attached to the wood beam. Alternatively, a smaller steel channel can be added at the bottom of the beam and supported by supports to boost the strength of an existing beam during a redesign. It could also be used as a cap on top of the beam to add more strength during home construction.
Steel channels are frequently used to make car frames. The primary frame rails run from the front to the back of the vehicle and are usually made of heavy-duty steel channels. Cross members, braces, and structural components like radiator supports can all be made from lighter steel channels. Steel channel provides adequate strength and rigidity in a vehicle to prevent excessive flexing while still allowing for some movement to compensate for the torque produced by the engine.
