What We Do

Stair Master supply a lightweight mould (permanent formwork) that can be quickly and easily used to construct a finished concrete stair on site.

Our formwork already has a layer of steel reinforcement in the base and remains in place after the concrete has been poured. It is made of durable galvanized steel which protects the stair from damage and gives a good finish.

Above all, Our vision is to complete contracts Safely, to the highest possible Quality, on Time and within Budget. This vision is dependent, above all, on planning. Put simply our belief is that any operation that is planned correctly will be accomplished safely. This goal forms part of our Health and Safety initiative.

Why Choose Us

  • Permanent formwork manufactured off-site
  • Formwork is lightweight
  • Formwork has a hard-wearing steel nosing on risers.
  • Stair flights have choice of straight stringer profile
  • The cost of a finished stair is very competitive against precast or cast insitu stairs.
  • 2 men can achieve 2 flights and landings in under 6 hours.
  • Less crane time – Can block and tackle and sort out by hand
  • No redesign required
  • Experience of complex installation
  • StairMaster work from existing architects/engineers drawings to design the stair formwork

How Stairmaster Works

Stair Master do not design the stairs as such, rather we design the formwork for the stair that the Architect & Engineer have drawn.

Using existing drawings, Stair Master incorporate the Architect & Engineers dimensions to design the formwork for the flights only. Half landings are constructed in-situ on site by others.

  • Customer issues Architects & Engineers Construction drawings to Stair Master.
  • Based on Architects & Engineers drawings, Stair Master generate a set of approval drawings for the stair flights.
  • Approval drawings sent to customer for comments/approval by both Architect & Engineer.
  • Comments are incorporated & updated on the approval drawings, until Status A is granted.
  • Upon receipt of Status A, Stair Master issue Construction Drawings & begin manufacture.

Frequently Asked Questions

Architects Answers

1 Does the stair have to be painted?
A. Not necessarily, the most budget finish for a back of house stair would be a colour contrast/non slip nosing and bare concrete. However the usual finish would be painted.

2. What finishes can be applied to the stair?
A. The very same as an insitu concrete stair or a precast stair. Suitable for screeds, linoleum, carpet, nosings etc.

3. What is the benefit of choosing the ‘standard’, straight stringer profile over the cut profile version?
A. With the straight stringer you remove the need for an mdf string or aluminium trim to be post fixed to the outside of the stair flight-reducing cost and trades in the stair core. It also allows the bottom rail of the handrail to be lifted higher, thus avoiding swan-necks at junctions in many places.

4. What finish do Stair Master supply on handrails?
A. Shotblasted and primed OR galvanised (for external stairs). A final paint finish will need to be applied following installation.

5. How do the stair flights connect to landings?
A. Landings are formed up insitu and Stair Master flights sit on top of them prior to concrete being cast. We incorporate a small ‘bent landing’ top and bottom in order to create a tight ‘seal’ or connection.

6. What is the appearance of the soffit?
A. We supply a completely flat soffit which will not chip/need making good. On either side there is a straight 30mm wide fold which is 2mm thick and gives the clue that this is steel rather than precast.

7. How should we design the stairs to use Stair Master?
A. As per a normal insitu concrete stair. Then we will adopt your riser heights, going sizes etc in our formwork design.

8. What clearance do you need between flights in order to have a side fix handrail?
A. 150mm.

9. Do you supply an internally mounted handrail?
A. Yes.

10. We have a design that is a little different from your typical details, can you accommodate this?
A. Yes, although we may have to advise on cost implications for other designs/materials etc.

11. Do Stair Master also supply a wall mounted handrail to match the full height rails?
A. Yes.

12. If we require a stainless steel and glass or other high end handrail, can you supply this?
A. Yes, although we will usually supply a temp rail with the stairs in the build phase and then post fix this sort of rail at the end.

Engineers Answers

1. How should we design stairs for Stair Master?
A. As per an ordinary insitu concrete stair. We will integrate your waste/throat thickness and steel into our flights.

2. Do Stair Master detail the steel needed for the flights and landings?
A. No, typically we take an existing insitu/precast stair design and incorporate the steel sizes and centres shown into our formwork for the stair flights. Landing steel is placed on site.

3. We haven’t yet designed the stairs for our site, are Stair Master able to do this?
A. Yes, please speak to us about a price/lead time for this.

4. Is Stair Master formwork structural?
A. No. Although it will have some structural benefit (it is made in galvanised steel sheet with welded connections) we assume that there is none at all. It is intended merely as a permanent formwork.

5. What fire rating comes with Stair Master flights?
A. We usually include reinforcement with 35mm of cover to the base of the soffit which will give a 2 hour fire rating, however if the engineer specifies differently then we will include as requested.

6. Do you have calculations for your handrails to demonstrate their strength?
A. Yes, available on request.

7. What testing have you carried out on your lifting hooks?
A. We have carried out Zurich lab destructive testing to verify that the capability of our lifting hooks is overrated by a factor of 24 or more for a typical stair flight.
