Rust Prevention Tips and Indications That Your Metal Door Needs Replacement

Exterior doors play a vital role in securing your property or business, so maintaining them is of utmost importance. One issue that can compromise the security and functionality of metal doors, hollow metal doors, and metal storefront doors is rust. Regularly inspecting your doors for rust damage can help prevent security issues or the need for either commercial door repair or door replacements.

What is Rust? Understanding Rust and Its Formation

Rust is the result of oxidation in metal doors, particularly those made of iron or steel, as well as door hardware such as knobs, hinges, and locks. Scientifically known as iron oxide, rust forms when iron is exposed to moisture and oxygen, making weather exposure a significant risk factor. To preserve the integrity and appearance of your metal doors, it is crucial to take preventive measures against rust.

Recognizing the Signs of Rust

When wet, rust often runs, leaving streaks near the hinges or door knobs, but it can appear anywhere iron is exposed to moisture and oxygen. Rusty door hinges are particularly susceptible due to their constant exposure to moisture and friction. Initially, rust is merely an unsightly blemish, but if left untreated, it can eventually eat away at the metal and compromise the door's structural integrity.

How to Prevent Rust on Metal Doors, Hardware, and Hinges

  • Install a drip cap to prevent moisture from rain and snow from accumulating on top of your doors.
  • Seal the door by applying a rust-proof primer before painting. This helps prevent rust formation if the door is scratched or if the paint chips or peels.
  • Regularly clean the door by wiping or washing it to remove dust, debris, and any existing moisture, thereby reducing the likelihood of rust.
  • Use rust-resistant materials for door hinges, such as stainless steel or brass, and apply rust-inhibiting coatings or lubricants to prevent rust formation.

  • Apply a coat of rust-proof primer to the affected area.
  • Finish with a coat of high-quality paint.
