Rust can make a commercial door a hard-to-operate eyesore. Although metal doors are practical and durable, they are unfortunately susceptible to corrosion, especially in humid or coastal regions. Automatic Door Specialists in Waipahu, HI, has served the local community for over 30 years. Here, they explain what causes commercial door corrosion and how you can prevent it.

A Guide to Metal Commercial Door Corrosion

What Causes Corrosion?

Prolonged exposure to water is the primary cause of corrosion. Rain, humidity, leaks, and spills can infiltrate the door frame, where that water can take quite a while to evaporate, resulting in rust. Salt doesn’t cause corrosion on its own, but it accelerates the process when mixed with moisture. This is why coastal areas like Hawaii are particularly prone to metal corrosion. 

Why Is It a Problem?

When a metal door corrodes, its protective abilities weaken, allowing unwanted elements to infiltrate the barrier, which can include anything from dirt and allergens to insects and rodents. As a commercial business or property owner, your responsibility is to protect inhabitants or guests from these outside threats. Corrosion also allows for air leaks, which reduces energy efficiency to cause a spike in your heating and cooling bills.

How Can You Prevent It? 

The best way to prevent corrosion is to keep your doorway free of salt and moisture. Don’t use commercial rust prevention sprays because these are ineffective. Rust corrodes from the inside out, so spraying the outside will not do any good. You can use a jamb patch kit to repair mild corrosion. Unfortunately, in coastal areas like Hawaii, it can be extremely challenging to avoid corrosion altogether. If your door is already corroded, rely on a commercial door repair professional to fix it.
