How to Protect Corrugated Steel Siding from Corrosion How to Protect Corrugated Steel Siding from Corrosion

Corrugated steel siding continues to be a popular choice for siding for many homeowners. It has several benefits which partly accounts for its high popularity with homeowners. Steel siding is one of the most durable siding materials available. It also has a high resilience. The wavelike structure of corrugated steel adds to the strength of the siding. Steel siding is fire resistant, bug resistant and will not rot. Besides, it is an affordable choice in siding materials which appeals to many homeowners. On the down side, steel siding is susceptible to corrosion with time, especially if not protected. Below is a guide that will help protect your steel siding from corrosion. For the most effective results, it is best to use a combination of methods. This will boost the efficacy of the protective barrier applied to your steel siding.

Painting

Anti-corrosive paints are commonly used to provide barrier protection to steel siding. Paints are used together with a primer. The paints contain elements of zinc or aluminum with a silicone resin to protect the steel siding. Painting can be done whenever the weather is suitable. It is best to paint in cool, dry weather. However, once applied, a coat of paint isn’t completely moisture proof. When exposed to moisture long enough, corrosion inevitably occurs. However, the beauty of using paints to protect steel siding is that you get to choose whatever color you prefer. This gives you more flexibility in achieving the desired color scheme for your home.

Galvanizing

Zinc and aluminum are the most commonly used materials to galvanize steel siding. The entire surface area of the siding is coated with the zinc or aluminum alloy. When properly applied, they act as a barrier to the agents of corrosion, mainly moisture and temperature. The agents of corrosion will attack the galvanizing metal and gradually destroy it. The protective coating is sacrificed but the steel siding remains unaffected by corrosion. Since the galvanizing metal wears away with time, it becomes necessary to galvanize steel siding on a regular basis.

Electroplating

This involves coating the steel siding with a thin layer of another protective metal. Zinc, chromium, cadmium or nickel may be used as the coating. Not only does electroplating give the steel siding protection against corrosion, it also improves the appearance by giving it a shiny look. Electroplating involves electrolysis being conducted in an electrolytic bath using electricity. Electroplating is best undertaken by a professional due to the technical process involved.

Zinc Spraying

This involves spraying zinc alloy onto the steel siding. Special tools are used to spray the zinc alloy. It is important to spray periodically to maintain the zinc barrier because it consists of a thin protective coat. Spraying every 2 to 3 years will provide effective protection to steel siding against corrosion. If you live in an area that has high atmospheric moisture and salts it is best to spray more frequently. This will provide better protection against corrosion.
