Strut Channel Flexible Support Systems


What is Strut Channel?

Strut channelling is a *Unistrut compatible product, since the invention of *Unistrut it has become the market leader and go to structural system for many trades, like HVAC Engineers, Electricians & Air Con Engineers, these are just a few examples. They lead in the industry with a very comprehensive selection of fittings. Since the expiry of the original patent many other manufacturers now produce a *Unistrut compatible product that can now be used, UK Strut is one of these.

People ask what types of strut channel are available. It’s not complicated but there are a few variations that ultimately can save you money rather than over engineering your installation.


Firstly, there are several finishes:


PG = Pre-Galvanised

The steel Struts and components are dipped in a galvanizing bath of molten zinc for a period of time. When the Strut is removed from the galvanising bath, excess zinc is removed. The Strut Channel ends up with a relatively thin galvanized coating of zinc. Pre-Galv. is normally used for indoor applications.


HDG = Hot Dipped Galvanised

This involves bathing the complete Strut channel into a bath of pure liquid zinc. This ensures overall coverage of the Strut Channel, including the external and internal surfaces. Hot dip galvanization results in a thicker zinc coating than pre-galvanization. A metallurgical bond forms between the Strut product and the zinc layer, hence providing substantial protection against corrosion. Hot Dipped Galv. is normally used for outdoor applications.


Secondly, there are different thicknesses:


(2.5mm) Heavy Duty

This is by far in industry the norm, its 2.5mm thick and what all trades will recognise as the normal Strut Channel.


(1.5mm) Light Duty

This is obviously a lighter duty specification Strut Channel. Not often used in industry simply due to the fact they don’t want to end up mixing and matching different thicknesses. It’s ideal as a lighter solution for example; mounting of light equipment, creating shelving or even holding up suspended ceiling grids.

Unistrut compatible refers to the majority of the strut channel products we sell on this site. We do not sell the Unistrut brand of products. It’s a non-welded continuous channel that can be used to create frames and supports for a multitude of uses. In its unique design it can be used without any drilling whatsoever, its fully customisable, can be simply dismantled or adjusted as and when required. It really is a very adaptable product that’s been used the world over for many many years.

When and where was Unistrut Invented?

Unistrut was invented in America in the 1920’s, it was invented by a gentleman called Charles Attwood. On a chance meeting during a commercial flight Charles met Mr Walt Disney, from that meeting Walt Disney created a video on Unistrut in the 1940’s, watch it here on You tube.
