  • The steel doors and windows system can achieve a variety of textures along with the combinations of different types and materials of profiles
  • Galvanised steel profile system: can have a variety of colours through high-temperature spray.
  • Stainless steel profile system: can be processed into embossed, mirrored, or brushed surface effect; wearing coatings made of antique or real copper and 24k gold via vacuum plating are also available.
  • All galvanised and stainless steel profile systems and aluminium alloy systems can be combined on demand.

Our diversified choices of personalised profiles also allow architects to imagine buildings with a more elegant and transparent architectural appearance.
