Top quality for outside use thanks to the anodized aluminium
Outside nature can be hard for furniture and staircases: wind, dust, salt at the sea side, water, humidity, ... You should take this into consideration if you want to invest in an outdoor staircase, unless you want to buy each few years a new one.
Galvanized steel could be a good solution.
But if aesthetics and nice design are also important for you, it becomes difficult to find a good solution.
The outdoor stairs of Graah might be a better choice for you. The anodization protects the stairs against scratches.
At the company we have a professional powder coating line and a large stock of different colors. The powder coating we use is very resistant to intensive use of your stair.
You have the choice between more than 6000 different colors. If you give us the RAL code of your windows and/or doors, we will lacquer your staircase in exactly the same color.
At Graah we strongly recommend anodized (and not lacquered) aluminium stairs for outdoor.
