The Science Behind Galvanization

Galvanization is a process that involves coating steel with a protective layer of zinc. This technique has been used for
centuries to enhance the durability of metal products, including metal siding panels for sheds. The zinc coating acts as
a sacrificial layer, corroding before the underlying steel and thus protecting it from rust and corrosion. This process
significantly extends the lifespan of the metal siding panels, making them a popular choice for exterior cladding
solutions.

The galvanization process can be carried out in different ways, with hot-dip galvanization being the most common
method for metal siding panels. In this process, the steel panels are immersed in a bath of molten zinc, ensuring a
uniform and thick protective coating. The result is a durable finish that can withstand harsh weather conditions and
resist corrosion for many years.

Galvalume: The Advanced Alternative

Galvalume is a more advanced variation of the galvanization process, offering even greater protection for metal siding
panels. This finish combines the corrosion resistance of aluminum with the sacrificial protection of zinc. The coating
