Unitrunk has added a ZM (zinc-magnesium) finish to its Speedway cable ladder range. The ZM finish was already available on Unitrunk's cable tray, trunking and channel.
Why ZM?
- Corrosion protection on par with hot-dip galvanised steel, and better than conventional zinc coatings.
- Made to BS EN 10346.
- Shorter lead times: the coating is applied to the steel before the ladder is made, so there's no separate galvanising step after manufacture.
- Lower carbon: fewer processing stages and fewer transport journeys.
Where to use it
Match the finish to the actual installation environment and project specification. Ask us to check the range and lead time.
