Is Powder Coating the Best Finish for Steel Gates?

Are There Any Alternatives to Powder Coating? 

Yes there are a few other options available to choose from.
Other common finishes for steel gates include:

• Galvanising – this is where the steel is dipped in molten zinc for rust protection. This is often used as a base coat before powder coating, but commonly used on industrial sites.
• Wet Paint Systems – these are more traditional and can be applied on-site, but are less durable.
• Patinated or Raw Steel – occasionally used for aesthetic effect but require more upkeep and offer limited protection.
• Hammerite or Spray Paint Finishes – these are low-cost alternatives that offer minimal long-term protection. Often used by budget installers, but prone to flaking and early rust. 

What’s the Best Finish for a Long-Lasting Steel Gate? 

For most customers, a zinc-rich base layer followed by powder coating is the gold standard for steel gates.

At Security Control Systems (SCS), we prefer to shotblast gates in their raw steel form, then apply a zinc spray before powder coating. This ensures the best possible surface preparation and corrosion resistance. Powder coating on top of zinc provides aesthetic appeal and a hard, weather-resistant outer shell in improves the durability.

While this process is more expensive than hammerite or simple wet spray paints, the additional cost is a no-brainer. It delivers vastly superior performance, longevity, and finish.

Absolutely. All SCS steel gates can be fully powder coated in your choice of colour and finish. We also ensure proper surface preparation, including shot blasting and zinc spraying, to maximise adhesion and durability.
