Galvanized steel, architectural aluminium, solar shading, curtain wall, facade, cladding,  perforated and expanded aluminium, windows, trims, fittings.

Description

Stone finishes are a sub-set of the Landscape Collection. Formulated from polyester resin systems to achieve excellent exterior durability, colour and gloss retention for architectural applications. Stone finishes can be applied to aluminium, mild steel, galvanized steel and most metal substrates. When used in combination with chrome-free pre-treatment. Stone finishes are long-lasting and hard-wearing with a fine texture and subtle tones.


Features and Benefits:

  • Cylindrical mandrel bending tested to ISO 1519, 5 mm mandrel, no cracking or detachment.
  • Resistance to boiling water, no blistering and no loss of adhesion.
