41 x 21 Slotted Channel (3M)

41×21 Slotted Channel (3M), pre-galvanised to BS EN 10346:2015, available in 3M lengths as standard.

These standard channel sections have been designed to provide an economical and versatile solution to support problems and industrial framing.

At the same time, having a wide flat surface provides support and allows the attachment of items easily.   Large objects supported by steel channels absorb flex and other forces that would otherwise damage more rigid I or H Beams*.

It is the radii** of the inner corners of steel channels that provide the required rigidity and strength to support steel angles and other construction and structural tasks.

‍

* To clarify, a beam with a cross-section shaped like an I or H is an I beam.

**  A line segment extending from the center of a circle or sphere to the circumference or bounding surface.
