Product Advantages
1.Available for customized specification on customers’ request.
2.Perfect Corrosion Resistance. The service life of galvalume is 3-6times as long as that of galvanized surface.
3.Perfect Processing Performance. Fully meet the requirement of roll processing, stamping, bending, ect.
4.Perfect Light Refelectivity. The ability of reflecting light and heat is twice that of galvanizing.
5.Perfect Heat Resistance. Galvalume products can be used at 315 degree Celsius for a long time without discoloration.
6.Excellent adhesion between the paint. Easy to paint and can be painted without pretreatment and weathering.

Application

Galvalume steel coil has a wide range of applications, such as roof panels, wall panels, light steel keels, heating radiators, car bodies, fuel tanks, cable armored steel tapes, plastic greenhouses, granaries, shipping containers, household appliances and appliances, ovens, explosion-proof steel belts, outer covers of air conditioning and ventilation systems, solar water heaters, packaging boxes for chemical products, and color plate substrates, welded pipes, steel windows, cold-formed steel materials in the metallurgical industry, etc., have a very broad application prospect.

La bobina Galvalume tiene las características de la lámina de acero galvanizado en caliente y la lámina de acero de aluminio en caliente.
La estructura del revestimiento de la bobina galvalume (bobina aluzinco) es una aleación de Zn-Al y la composición del revestimiento es 55 % Al, 43,3 % Zn y 1,6 % Si. Debido a su excelente resistencia a la corrosión, este tipo de acero está reemplazando gradualmente al acero galvanizado y es ampliamente utilizado en todo el mundo.
