Hot-dipped Galvanized cold-rolled coil (Hot-dipped Galvanized)
Hot-dipped Galvanized cold-rolled coil (Hot-dipped Galvanized) has a thickness of dipped layer about 65 – 300 micron. With the ongoing hot-dipped process, the dipped layer is therefore well connected with the steel and gives a beautiful and shiny surface suited for the type of work that requires anti-rust conditions, such as electronic devices, computer cases, air pipes, ceiling frames and wall frames.

Aluzinc Steel Coil
This is a hot-dipped coil which has been coated with mix metal of 55% aluminum, 43.5% and 1.5% silicon. It prevents rust better than galvanized steel and is also lighter. Therefore, at present, it is more popular with customers looking for roofing frames and suitable for entrepreneurs who have a low budget but would like to build good quality factories. The hardness of mix metal coated steel, Aluzinc, that is popular nowadays can be categorized into two types: Aluzinc G550 with tensile strength at yield no less than 550 MPa, suitable for roll forming with high bending radius, and Aluzinc G300 with tensile strength at yield no less than 300 MPa, suitable for roll forming with low bending radius.
