اختيار التشطيب المناسب للأعمال المعدنية الخارجية

Finish is not colour. Finish is a system: preparation, primer, coat, thickness — and only then colour.

For outdoor steel in Egypt, the working answer is zinc-rich or galvanized preparation under a polyester powder coat of at least 80–120 microns. Matte black hides dust and reads architectural; graphite softens large surfaces; bronze tones belong to thresholds and details, not whole fences.

Custom RAL is available, and it should be used with intent: a gate in a project colour can be exactly right, or exactly wrong. Dark colours absorb heat and show dust; light colours show pollution. There is no neutral choice — only an informed one.

Ask for the system in writing: preparation grade, primer, DFT, warranty. A finish without a specification is a promise without a date.
