A look at Marshall Tufflex pre-galvanised steel cable tray systems for commercial electrical installs, including stand-off brackets and pre-made bends.
Marshall Tufflex has highlighted its pre-galvanised steel cable tray system, designed as a primary containment choice for internal commercial electrical installations. The range spans light-duty through to heavy-duty gauges to suit different cable loads and site requirements, accompanied by standard accessories including stand-off brackets, reducers, fixings, and pre-made bends.
Pre-galvanised steel remains the standard material choice for indoor commercial runs where protection against mechanical damage is required without the necessity for heavy hot-dipped galvanising. The inclusion of dedicated stand-off brackets and manufactured bends allows electricians to navigate structural obstacles and maintain clear separation from mounting surfaces without needing extensive on-site metal fabrication.
Using pre-formed fittings such as reducers and bends speeds up containment runs compared to hand-cutting and notch-bending straight lengths. This reduces installation labor times and minimises bare, exposed cut edges that require cold-galvanising spray treatments on site.
What does this mean for a UK tradesperson or DIYer actually buying this kit — does it change what they should pay, buy, or watch out for?
For commercial electricians and contractors purchasing containment, this range represents a standard, readily available option across electrical wholesalers. When pricing containment jobs, factor in the cost of factory-made bends and reducers against labor rates; while individual fittings add to the initial materials bill, they significantly reduce installation hours compared to manual cutting. Installers working in damp or exposed environments should ensure pre-galvanised tray meets the necessary corrosion resistance specs, as outdoor or wash-down areas typically require hot-dipped galvanised or stainless steel alternatives instead.
