Steel Finishes & Protection

Explore practical guides to galvanising, powder coating and choosing protective finishes for outdoor steel barriers, bollards and gates. This section explains the differences between galvanised steel, powder-coated steel and galvanised then powder-coated finishes, helping you compare corrosion protection, appearance and maintenance needs for your site.

Learn about hot-dip galvanising and the role of its zinc coating in protecting steel from corrosion. Our articles explore specifications such as BS EN ISO 1461, typical finish characteristics and questions to ask when ordering galvanised products. Find guidance on surface appearance, weathering and why a protective finish should be assessed for its intended purpose as well as its appearance.

Discover how powder coating provides colour and a finished surface, with RAL colour options available across much of the Aremco range. Read about surface preparation and the differences between powder coating applied directly to steel and powder coating over galvanising. The combined approach, often called a duplex system, brings together zinc protection and a coloured outer coating.

Explore factors that affect coating performance, including exposure to moisture, road salt, coastal conditions, surface damage and maintenance. No single lifespan applies to every installation: the environment, coating specification and condition of the product all matter. Our guides help you identify the questions worth discussing before choosing a finish for an exposed or demanding location.

Find practical advice on cleaning, inspecting damaged areas and maintaining finishes around bases, fixings and moving parts. Whether you are specifying new products or caring for an existing installation, Aremco Barriers shares guidance drawn from our experience manufacturing steel access control products in the West Midlands.

Use these articles to make informed choices about finishes for your project and discuss suitable options with our team.
