To keep the flight open and light whilst adhering with the 100mm gap rule – there are the following solutions:

· Steel Riser Bars

· L shaped treads with timber downstand

· Half Glass Riser Pieces

· Full Glass Riser

· Full closed risers with timber


The riser height, pitch angle and going depth are created specifically to suit the opening, staircase configuration and floor to floor height of the project. The stair is ‘dry’ fitted in the factory before dispatch to ensure all parts fit together.
