STAIRCASE DESIGNS

Guidance

Here at CICS we offer a range of staircases for mezzanine floors, all designed to comply with the latest building regulations requirements. Whether your new mezzanine is for increasing space in a warehouse, or perhaps you’d like to create a beautiful new office space, we’ll make sure that the staircases fit perfectly in line with the goals you’re looking to achieve.

General Access Staircase

When installing a new mezzanine floor you must fit at least one General Access Staircase, other types of stairs can be introduced thereafter depending on the mezzanine floor use. There are a variety of options available including the following.

General Access Stair (Industrial)

A maximum of 12 rises per flight except in small premises where 16 risers per flight is acceptable. When exceeding this allowance a landing tower must be introduced.

The treads must be closed with a non-slip surface and include contrasting noses, durbar steel is ideal for this application and used on all our standard staircases.

The maximum rise must not exceed 170mm and the maximum going should be no more than 250mm.

The distance between the handrail and the tread nose line should be between 900-1100mm.

300mm handrail extensions are required at the top and bottom of the staircase.

General Access Stair (Public)

Similar in design and appearance to the general access stair (industrial), however the clearance between handrail posts must be a minimum of 1200mm.

Utility Stair (Access)

Based on industrial settings, a minimum of 800mm is required between handrails with open contrasting rises, maximum rise of 190mm and maximum going of 250mm.

A maximum of 12 rises per flight except in small premises where 16 risers per flight is acceptable. When exceeding this allowance a landing tower must be introduced.

Utility Stair (Escape)

Design features to match the utility stair (access), however the treads noses do not need to be contrasting and you can increase the total number of risers to 25.

Mezzanine Floor Staircase Construction

Our staircases are fabricated using 200x10mm stringer plates with 50x50SHS posts and 50x25RHS horizontal rails.

Durbar treads are fitted as standard for industrial settings, however we can fabricate smooth treads for the application of carpet tiles or other finishes.

Using our in house spray facilities, we can paint your staircase any colour but as standard we offer grey or black.
