Aluminum is a chemical element. Its chemical symbol is al, and its atomic number is 13. Aluminum is the most abundant metal element in the crust, ranking third only to oxygen and silicon.

Aluminum is a metal element with the element symbol Al and atomic number 13. Its simple substance is a silver white light metal. It has ductility. Commodities are often made into rods, sheets, foils, powders, strips and filaments.

In order to ensure that the wall washer aluminum profiles have high wind pressure resistance, assembly performance, corrosion resistance and Decorative performance, the requirements for the comprehensive performance of aluminum alloy profiles are much higher than the industrial profile standards.
