Mezzanine Floor Ancillaries

Mezzanine floor ancillaries are one of the key reasons customers choose Pearson Knight designs. We have bespoke staircases for every mezzanine flooring  installation. We also can supply feature staircases with Stainless steel Balustrade and toughened clear or smoked Glass.  Whatever you requirements, we have the mezzanine floor ancillaries to satisfy all of your situations, either retail or commercial.

We  can advise you on alternatives where a Balustrade handrail is necessary because of
Public access, for example, Commercial / Retail Premises, Gymnasiums. We can offer a wide range of colour combinations of mezzanine floor staircases to ensure that your new mezzanine flooring reflects your corporate image. All our ancillaries and staircases are powder coated to give a highly durable finish with gloss retention.

We can also provide advice regarding relevant Building Regulations for Staircase and mezzanine floor ancillary requirements and also the travel distances for the proposed layout.

The Building Regulations have recently been amended to remove conflicting guidance across different documents. In particular, guidance for staircase design (previously covered by “Parts K & M”) has been combined into a single document: “Part K” – which became effective from 6th April 2013.

All our staircases are designed to meet the requirements of “Part K”, for use within industrial premises. Staircases for use within other types of premises (such as, commercial, retail, institutional, general public access etc.), may need to meet additional requirements, and can be quoted separately.

Staircase Design

Staircase design is covered by (amongst others) BS5395: Part 1, BS5395: Part 3 and BS5950: Part 5. General guidance on staircase design is contained within the new Approved Document Part K – 2013 (Section K1 – Stairs, Ladders and Ramps) of Building Regulations. This approved document supersedes previous guidance in Approved Documents Part M and Part K relating to staircases and guard railing.

For consideration of means of escape (MOE) in the event of fire, reference should be made to Approved Document Part B.

Building Regulations Approved Document Part K – 2013 Compliant Stairs/Handrail

There are now various options for staircases within Part K1 – Stairs, and the old Part K and Part M ‘ambulant disabled staircase’ has been superseded. The following stair options are now available:

General Access Stair – (Industrial)

General Access Stair – (Public Access)

Utility ‘Access’ Stair – (Industrial)

Utility ‘Escape’ Stair – (Industrial)

General guidance on the new requirement and characteristics are shown below:

All new mezzanine floors are now required to have a minimum of one General Access Stair. Where a floor has only one access stair, it MUST be of the General Access stair. Where a floor has more than one staircase, at least one must be of a General Access type. All other stairs can be deemed to be for escape purposes only, and be of the Utility ‘Escape’ stair type.

The width and number of stairs required is dependent on the number of persons using the floor area and travel distances.

Where the floor is a plant platform and the only access required is for maintenance, a Utility ‘Access’ stair is acceptable.

 General Access Stair (Industrial):

The General Access Stair (Industrial) would have 1000mm between handrails, have OPEN rises – standard up stand within industrial/storage premises and CLOSED rises – within office/retail premises.

Treads with contrasting nosing will be governed by a rise of 150mm (MIN) to 170mm (MAX) and going of250mm (MIN) to 400mm (MAX).

The maximum number of rises allowable is 12 rises per flight, except in ‘small and/or restricted’ premises, where 16 rises are allowable.

Handrail needs to be contrasting and be a minimum of 50mm diameter (50×25 RHS is acceptable), and this must protrude 300mm beyond both the top and bottom tread nosing, unless it causes an obstruction to a common access route.

 General Access Stair (Public Access):

The General Access Stair (Public Access) would be the same as the General Access Stair (Industrial) but would have a clear width between handrails of 1200mm. This stair will always have ‘CLOSED’ risers as well.

 Utility ‘Access’ Stair (Industrial):

The Utility ‘Access’ Stair (Industrial) would have a minimum of 800mm between handrails, have OPEN riser treads with contrasting nosing will be governed by a rise of 150mm (MIN) to 190mm (MAX) and going of 250mm (MIN) to 400mm (MAX).

The maximum number of rises allowable is 12 rises per flight, except in ‘small and/or restricted’ premises, where 16 rises are allowable.

Handrail needs to be a minimum of 50mm diameter (50×25 RHS is acceptable).

 Utility ‘Escape’ Stair (Industrial):

The Utility ‘Escape’ Stair (Industrial) would be the same as the Utility ‘Access’ Stair (Industrial) but would NO contrasting tread nosing’s, NO restriction on the number of treads – subject to practical limitations e.g. no more than 25 rises.

Other considerations:

An ‘Access Strategy Statement’ will sometimes overcome the requirement to provide a Disabled Persons Platform Lift by siting the provision of a General Access Stair (for Ambulant Disabled use) in lieu, and assuming that all facilities and areas are replicated on the ground floor accessible areas as are found on the mezzanine level.

Safety Gates

Designed to protect personnel at exposed opening points at the floor edge, safety gates can have a light-weight, fail-safe roll-over operation or be of the sliding ‘trombone’ type. They can accommodate standard sized pallets and require virtually no maintenance. The gates are powder coated to give a highly durable finish with excellent gloss retention.
