Marine Grade Cast Aluminium

A marine environment is classed as within a distance of 6 miles of salt water or tidal estuary, however, the salt can travel much further inland, dependant on weather conditions.

Until recently, all manufacturers of cast aluminium gutters have used aluminium that contains a significant amount of copper and zinc, which is susceptible to electrolytic attack by salt water.

Although powder coating can act as a protective covering to the standard grade aluminium, any damage to the powder coating can allow salt water to penetrate through to the aluminium and cause an electrolytic action causing the powder coating to lift from the aluminium.

In 2011 GMD Pennine Ltd are pleased to launch our new range of marine grade cast aluminium gutters and fittings to overcome problems caused through the marine environment.

Please contact our sales team for further information or a quotation on this range.
