Triangle

transparent / elegant / unique step

Triangle, technical engenuity

TECHNICAL INGENUITY

The Triangle loves to be admired from aside. Thanks to the use of aluminium the Triangle almost disappears in the background but not without putting an elegant accent, a triangular accent.

The stringers are underneath the steps. This way you can look at the steps from whatever position you are in.

The ribbed top of the steps are a perfect antiskid system.

The stringers as well as the steps are 100% made of aluminium. De hard top top layer (anodisation) protects the stair against scratches and makes it easy to maintain.
