Galvanised Only | KP Engineering can arrange to galvanise most of our products by using the hot dip method. The galvanising is silver or grey in colour and is likely to become darker over time as it weathers.
Galvanising will generally stop the metalwork from rusting, unless it has chipped, exposing the metalwork beneath. Site alterations can be made good by using a cold galvanising spray available from most DIY stores.
Galvanising is considered to be an industrial finish and does not always produce a smooth surface due to the process. Fettling is not included, so please be prepared to see some zinc residue on the surface. Furthermore, on hollow section steel, small vent holes will be visible.
The metalwork can be left as galvanised only or it can be painted over. Before painting, the surface should be lightly sanded down, then a mordant T-wash solution should be applied, before finally applying the paint.
A galvanised finish can also be powder coated prior to delivery or installation. (Please refer our Galvanised and Powder Coated finish for more information).
All our galvanising and powder coating processes are undertaken by an outside supplier. Hence we have no control over this process other than to supervise their quality. It is noted that whilst we take great care and attention to all our products, over time the galvanising or powder coating finishes may sustain scratches, chips or in the unlikely event wear away. If this occurs it may expose the metalwork to the elements, a situation that could lead to some rusting. As a result, no type of finishing is included in our guarantee.
