The Jack Zinc staircase is designed for exterior use with robust manufacture and hot galvanised steel for the treads, spine and balustrade. The Jack Zinc Modular Staircase is a clever design with a central interlocking spine which can provide a straight or L-shaped staircase. There are two versions for the L-shaped format, one with winder treads to make the quarter turn, and one with a quarter landing platform tread. The Jack Zinc modular staircase is also available in two widths to suit every project – 800mm, and 900mm.
Just choose the format for your project (straight or L from either of the two options), the right width and then it’s as easy as that!
