Prepainted aluminum coil for downpipes has surface electrostatic powder coating technology, can maintain the bright original color in the cold and high temperature, acid rain corrosion and other harsh environments. The downpipes made of prepainted aluminum coil are stable and solid, double multi-point fixing, simple design, easy installation, double fixing is not afraid of typhoon vibration, snow/ice accumulation pressure is not afraid of deformation, stable and assured. The prepainted aluminum coil is long-lasting and durable, the surface spraying antioxidant layer, corrosion resistance, cold resistance, high temperature resistance, pure color does not fade.
3003/3105 H24/H26 aluminum manganese alloy are used as prepainted aluminum coil for downpipes, commonly known as “anti rust aluminum”, high strength, better heat dissipation, strong resistance to pressure. 3000 series aluminum alloy is lightweight, has good plasticity, ductility, and is favored by large projects. The thickness of the aluminum coil for downpipes is generally between 0.65mm-1.2mm, the width is customized according to various types of pressing machines, generally between 500mm~1200mm, and the general width of the aluminum coil for gutter is between 575mm~600mm. The colors of aluminum coil for downpipes are white, black, coffee, beige, gray, brushed bronze, faux marble, frosted/matte, and custom colors are supported.
Aluminum gutter system in the North American market accounts for more than 80% of the entire market. Metal gutter system materials mainly include galvanized iron, prepainted aluminum coil for downpipes, zinc alloy and high-end copper materials. Among them, prepainted aluminum gutter system with its color effect, weather resistance and relative economy accounted for more than 90% of the metal gutter system market.
