Aluminum coil is a kind of metal sheet, melted by aluminum ingot, add different alloy, through casting rolling or hot rolling, cold rolling, annealing, shear and other processes into aluminum coil.
Because aluminum coil has:
1, small density, light weight.
2, easy to handle, can be strengthened.
3, plasticity, easy processing.
4, corrosion resistance.
5, no low temperature brittleness.
6. Good electrical and thermal conductivity.
7, sound absorption.
8. Nuclear radiation resistance.
9, beautiful, surface can be reprocessed and other advantages. So it's used a lot, 7% a year.
Characteristics of aluminum coil
1. No compound high temperature indentation on the surface. There is no residual stress and no deformation after shearing.
2. Painted wood grain, stone grain, realistic physical texture, there are fresh natural beauty. Design at will and do, give customers a wide range of personality choices, can enrich the humanistic connotation of products, give people more beautiful enjoyment.
3. The paint pattern is coated and baked at high temperature, with high gloss retention, good color stability and minimal color difference. Polyester paint warranty for 10 years, fluorocarbon paint warranty for more than 20 years.
4. High-quality aluminum, plastic and adhesive are selected and advanced composite process is adopted. Products with decorative plate required bending, bending strength, in the four seasons climate, wind pressure, temperature, humidity and other factors change, will not cause bending, deformation, expansion and so on.
5. Saline-alkali acid rain corrosion, its own corrosion will not produce live toadstools, does not release any toxic gas, does not cause keel and fixed parts rust, flame retardant.
