Steel channel are one of the most popular parts in construction and manufacturing. Apart from this, C channel & u channel are also used in our everyday life if you have so much attention to them like stair stringer. However, owing to its bending axis is not centered on the width of flanges, structural channel steel is not so strong as I beam or wide flange beam.
- Tracks & sliders for machines, doorways, etc..
- Posts and supports for building corners, walls & railings.
- Protective edges for walls.
- Decorative elements for constructions like ceiling channel system.
- Frames or framing material for construction, machines.
