Universal Stairs-Features

Introduction

Universal Stair from ASP provides the complete solution to building stair towers in both traditional and system scaffold structures. A range of self-contained, pre-assembled aluminium stair units, flat packed, which automatically adjust to a wide range of lift heights, making them ideal for use in tube and fitting scaffolds. Universal Stair also has applications away from scaffolding, wherever a simply deployed stair, which requires no skilled labour to erect, is required. Special hooks for use in formwork are available and Universal Stair will also find use by roofers and allied trades. Universal Stair is a simple self-contained product which is easy to store packed flat and can be collected or delivered on small vehicles including vans for the smaller models. Product selection is easy, depending only on the range of lift heights required, and users have the assurance that all models, in all possible positions, are fully-compliant with regulations. Non-scaffolding users will find Universal Stair easy to use, since there are no special skills involved in producing a first-class result. Universal stair is available in two tread widths 680mm(EX series) and 540mm(LR series).
