There are various types of staircases and hand rails available for our mezzanine floors. Our industrial steel staircase with galvanized steel hand and knee rail is the most economical design.
With the staircase you can replace the checker plate treads with steel grating or timber treads and you can have various stringer designs using either channel, flat bar, I-beams or even timber beams. You can also have a completely timber staircase. There are various angles available. Generally we use the 40 degree angle as it is easy to climb and does not take up too much space. The 45 degree angle uses less space but can be tricky coming down the stairs especially when you are carrying something. 35 Degrees is the most comfortable climb if you have the space available as the tread depth changes from 250mm to 275mm.
The minimum width of a staircase is generally 1 meter. Depending on what you are using the mezzanine floor for will depend on the legal minimum width you may use. In more public spaces it is advisable to have a tread width of no less than 1200mm and this can extend to about 2400mm. If the height of the mezzanine floor is more than 3 meters then it is advisable to have a centre landing. Depending on the space available for the staircase, the design could vary from a straight staircase to one with a landing, L-shaped or a dogleg staircase, spiral or semi-spiral.
The hand rail design for the mezzanine floor can vary from our standard industrial galvanized steel rail to a welded steel balustrade using anything from round, square and rectangular tubing to round, square and flat bar or you can have a completely timber rail or even a combination steel and timber hand rail. As another option you can add stainless steel tensioned cables to the balustrade.
