Powder Coating & Choosing a Colour

Powder coating applies a dry powder to the metal electrostatically, then bakes it so it fuses into a continuous film. There is no solvent, and the result is a harder, thicker and more uniform finish than wet paint applied on site.

The practical difference is that the finish is part of the product rather than something applied to it afterwards. There is no repainting cycle in the way a timber or wet-painted steel fence has one.

It is not indestructible. A deep scratch that goes through the coating exposes the aluminium underneath — which will not rust, but will show. Powder coating on aluminium is a cosmetic and protective layer over a material that does not corrode anyway, which is a fundamentally better arrangement than paint over steel.

The most reliable approach is to match something that already exists on the house rather than choosing in isolation. Roof colour, window frames, gutters, garage door, existing fencing — picking up one of those makes the gate look like part of the house rather than an addition.

Dark greys and blacks dominate contemporary work for a reason: they recede visually, so the gate reads as a clean boundary rather than as an object. Lighter colours advance and draw attention, which is what you want on a picket frontage and usually not what you want on a large driveway gate.

Woodgrain-look coatings are worth considering where a metal gate needs to sit alongside timber. The pedestrian gate in our gallery next to a stained paling fence shows the effect — it relates to the timber without pretending to be it.

Frame, posts and infill can each be a different colour. On picket fencing this is what produces the combinations in our photography — cream pickets with green posts, white with black, cream with red.

It works best when one element is clearly dominant and the other is a deliberate accent. Picking out the posts in a deeper colour against lighter infill reads as a detail; using two colours of similar weight tends to look indecisive.

On period homes especially, a two-tone frontage in heritage colours can transform how the house presents.

Powder-coated finishes benefit from being washed down. Not because they are fragile, but because airborne salt, dust and pollution accumulate on any outdoor surface and gradually dull it.

Coastal properties need this more often than inland ones — salt is the single biggest factor in how long any outdoor finish keeps looking new. Fresh water and a soft brush is all that is required; no solvents and nothing abrasive.
