As a trusted and accredited company, we always provide structural calculations to building control which ensure that we adhere to structural safety.
Although there is some confusion out there regarding concrete slab core samples, it is not a requirement for building regulations. However you may be asked for your landlord to undertake the test to provide evidence the existing slab can withstand the loads imposed by the mezzanine.
Fire safety is always a large part of our design process, making sure that there is always a means of escape in the unlikely event of a fire or emergency situation. We always make sure that 1-hour fire resistance is included if required when designing and fitting mezzanine floors, to ensure we comply with Part B of Building Regulations.
The height and safety of our mezzanines is always determined and examined within the architectural design process, to ensure we are compliant with Part K and Part M of Building Regulations.
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.
Similar in design and appearance to the general access stair (industrial), however the clearance between handrail posts must be a minimum of 1200mm.
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.
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.
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.
