Maintaining a steel gate: Our tips for optimal longevity

Introduction

A steel gate is a lasting investment, combining robustness, security, and aesthetics. However, to ensure it retains its qualities over the years, regular maintenance is essential. As metalwork experts, Staalmat Métallerie guides you through the key steps to maintain your steel gate, whether it's painted, galvanized, or combined with other materials such as wood or sheet metal. Discover our tips for preserving its shine and functionality, year after year.

Why maintain your steel gate?

Steel is a strong material, but it is not immune to corrosion , scratches , or finish degradation . Proper maintenance helps to:

• Extend the lifespan of the gate.

• Maintain its aesthetic appearance (avoid rust, traces of pollution).

• Maintaining its performance (proper functioning of hinges, motorization, etc.).

Avoid repair costs related to negligence.

Regular cleaning: The basis of maintenance

Frequency

• Light cleaning : Every 2 to 3 months (or more often in urban or coastal environments).

• Thorough cleaning : 1 to 2 times per year.

Materials needed

• Soapy water (mild soap or specific product for metal).

• Sponge or microfiber cloth.

• Soft brush (for patterns or perforations).

• Water jet (without high pressure to avoid damaging the seals or paintwork).

Steps

• Rinse the gate with clean water to remove dust.

• Wash with a sponge soaked in soapy water, paying particular attention to exposed areas (handles, hinges).

• Rinse again and dry with a clean cloth to avoid watermarks.

Inspect the gate for any signs of rust or deterioration.

Tip : Avoid abrasive products or harsh detergents (bleach, acid), which can damage the finish.

Corrosion protection

Galvanization

If your gate is galvanized (coated with a layer of zinc), it is naturally protected against rust. However, in case of a deep scratch:

• Apply a rust-preventative product to the affected area.

• Touch up with a suitable paint (paint for galvanized metal).

Paint

For painted gates:

• Check the condition of the paintwork 1 to 2 times a year.

• Touch up the chips with paint of the same color and quality (preferably glycerophthalic or epoxy paints for better adhesion).

• Apply a protective layer (wax or specific product) to enhance resistance to UV rays and weathering.

Treatment of rusted areas

If rust appears:

1. Brush the area with a wire brush or fine sandpaper.

2. Apply a rust converter to neutralize the corrosion.

3. Paint the area with rust-resistant paint.

   
   

Maintenance of mechanical components

Hinges and locks

• Lubricate the hinges and mechanisms 1 to 2 times a year with a dry lubricant (such as silicone grease or PTFE spray) to prevent squeaking and premature wear.

• Check that the screws and bolts are tight , and tighten if necessary.

  
  

Engine (if applicable)

• Clean the rails and guide wheels.

• Check that the sensors and the opening system are functioning correctly .

• Hire a professional for annual maintenance if your gate is motorized.

Specific maintenance depending on the type of filling

Wood filling

• Treat the wood every 1 to 2 years with a saturator or stain to protect it from moisture.

• Check the fixings between the steel and the wood, and replace any rusty screws.

Sheet metal filling (solid or perforated)

• Clean the perforations with a soft brush to prevent the accumulation of dirt.

• Inspect the welds and joints for any structural weaknesses.

When should you call in a professional?

Certain situations require the intervention of an expert:

• Advanced corrosion or hole in the steel.

• Engine problem (abnormal noises, blockage).

• Replacement of parts (hinges, locks, panels).

• Complete painting of the gate (for a uniform and durable result).
