Description
The GTM1 is a 125 x 100mm moulded ogee aluminium gutter length, cast in the traditional 5" x 4" pattern and supplied in 1.83 metre (6 foot) lengths. Gravity cast from marine-grade aluminium, it reproduces the decorative S-shaped ogee moulding of 19th-century cast iron, with the crisp shadow line period and listed buildings call for. The finish is Interpon D1036 architectural-grade polyester powder coat for lasting durability, and the casting carries a functional life of over 50 years. Made in-house and sold factory-direct.
Moulded ogee is the definitive heritage profile — the correct choice for Victorian, Edwardian, period and conservation-area properties, and a direct visual replacement for ageing cast iron. It gives that traditional appearance without the weight, the rust or the repeated repainting, and it will not crack in frost. The colour is over-paintable if a scheme changes, and the aluminium is fully recyclable at end of life.
This is a single 1.83 metre length, complete with an integral internal jointing spigot: the spigot end locates into the next length, sealed and secured to form a continuous run (a separate jointer, GTM2, is available where required). For the full range of angles, outlets, stop ends, brackets and matching downpipes, see our aluminium moulded ogee gutters range.
Colour: available across a wide range of RAL colours to order, on a 10 working-day lead time.
