In addition to steel structures being hot-dip galvanized, they can also be finished in a variety of RAL colours through a powder coating process.
What is powder coating?
Powder coating is a dry finishing process, applied as a free flowing dry powder. Differing from conventional liquid paint, this method of coating does not require a solvent to keep the binder and filler parts in suspension; the coating is typically applied electrostatically, where electrically charged powder coating material is spray applied to a work piece.
Powder coating can produce thicker coatings than liquid alternatives, without running or sagging and also produces minimal appearance differences, resulting in a smoother finish and greater colour longevity for your canopy.
What is a RAL colour?
The RAL colour system is the most popular Central European Colour Standard in use today and you will see the colours used in architecture, construction, industry, recreation and road safety.
The system is specially designed to be used for powder coating purposes and covers a wide spectrum of colours. This means that a canopy can be manufactured to the colour of your choice, allowing further personalisation of your structure and the capability to fit into its existing surroundings.
Fordingbridge offer a range of standard RAL colours for your structure – see our RAL Colour Chart (PDF, 339Kb).
