Coatings

Our gutters and components are available in two options on material and various colour options. See below for more info. 

Colorlume Coated Coil

Colorlume is a pre-painted Aluminium-zinc coated steel with a distinctive smooth, flat fine spangle. The coating composition by weight is 55% aluminium and the balance zinc alloys applied by the continuous hot-dip coating process, similar to that of continuous galvanizing. It has both aluminium-unique corrosion resistance, heat resistance and zinc-unique "galvanic behavior". Worldwide, Colorlume is used in white goods industry, automotive parts, roofing products, rainwater goods etc. and can be produced in a variety of specs from soft drawing quality to high tensile roof sheeting. 

Aluminium Coated Coil

Coated (pre-painted) aluminium coil, is painted with colours before it is cut, bent or punched; therefore it differs from spray painting (powder coating). 70% Of metallic materials used on the surface of buildings are pre-painted. 
Coating line is specialised for aluminium coil, working automatically, continuously and effectively, the coating is stable and smooth. Both sides of the coil could be coated with 2 layers at the same time, to avoid the coil from being over-baked.

Aluminium coated coils are made mainly from aluminium alloy a3105h24 or a3003h24, both sides are covered with pre-paint, with thickness of 18-20 microns or 25-28 microns as required. There are 5 different colours available for gutters. We supply Ivory, Charcoal, Brown, Green and White. Thickness Available: 0.6mm and 0.8mm.
