Channels and trunking are manufactured by a rolling machine or press brake turning the channel or trunking inwards with a continuous opening.

The opening of these channels and trunking comes in different sizes, thicknesses and are normally made from Z275 Pre- galvanised material ASTM 635M.

A full range of accessories are also available for each size, and all bends can be supplied in 90 or 45 degrees.

Some trunking has a build in splice for easy, less labour and more cost-effective installations.
