Aluminum Corrugated Sheet / Aluminum Roofing Sheet
Aluminum Corrugated Sheet, also known as Aluminum Roofing Sheet or Profiled Aluminum Sheet, is a corrugated or trapezoidal grooved roofing/wall panel product formed by roll-forming high-quality aluminum sheets or coils through cold-bending processes. The corrugated structure significantly improves the section modulus and load-bearing capacity while retaining the excellent properties of aluminum such as light weight, high strength, and corrosion resistance. With outstanding advantages including aesthetic appearance, easy installation, long service life, and 100% recyclability, aluminum corrugated sheets are ideal roofing and cladding materials for industrial plants, civil buildings, temporary facilities, and more.
