Select colours to add them to your project enquiry.

Every standard colour comes in gloss or matt, except RAL 1035 Pearl beige, which is made in 88% gloss only and takes longer to arrive.

The full RAL Classic range

Over 200 RAL Classic colours in all. Those outside the standard range cost extra: gloss 30 or 77 on aluminium, gloss 20 on wood.

Also available

  • Glazing beads Supplied in grey. RAL 7035Light grey
  • Two-colour windows The frame in one colour and the sashes in another, at extra cost. Mullions and transoms take the frame colour.
  • Granite textured coatings A powder coat that looks and feels like rough-cut granite, from white through greys and blues to black. VELFAC’s UK team advise against it beside aluminium cills or pressings, as a colour match cannot be guaranteed.
  • Metallic coatings A powder coat with a metallic sheen, offered alongside the granite finishes as a special option. Like granite, it is quoted per project.
  • Anodised finishes A protective anodised surface in silver or bronze. It is a natural process, so shades can vary between elements and from the sample.
  • Raw aluminium Aluminium left without surface treatment, subject to VELFAC’s reservations. Not available on sandwich panels.
  • NCS colours A range of NCS colours for the timber inside, at extra cost.

Colours on screen are a guide only, and pearl and metallic finishes cannot be shown. Add your choices to your project enquiry and we will go through them with you.
