Premade steel stair stringers with hardwood kwila treads
Galvanised steel kitset stairs with boltdown or cast in connections

LevelMaster supplies the only adjustable stair stringer base that has been properly engineered and designed. Therefore all stair stringers are manufactured to the requirements of the Australian Building code and to suit standard rise and going measurements:

  • rise: 175mm

  • going: 250mm.

Two types of stair stringers

Our stair stringers are available in two different types:

  • cast in

  • bolt down.

Make sure you choose the correct stair stringer for your needs based on how you plan to fix the base of the stringer (cased in concrete or bolted down) both types cost the same.

Special rise requirements

If you have special rise requirements, we can also supply non-standard rise brackets. Furthermore these stair brackets are only available from LevelMaster and enable you to change the rise on 1 stair stringer tread or all of them. We also have hardwood step treads in several sizes, and stock the coach bolts to suit. You can purchase your stringers, treads and bolts in 1 order.

Stair stringer treads: rise and going

Our stair stringers range from 1-17 treads (steps) and are made for standard ‘rise’ and ‘going’.

The rise is the vertical measurement taken from one step level to the next. Standard rise is 175mm.

The going is the horizontal measurement taken from the front of one step to the next. Standard going is 250mm

Stair calculator table

To work out the correct size stair stringer, you will need to know your height to deck. This can be found by measuring the vertical distance from the ground level to the height of the deck that you wish to connect.

Note: Also check that there will be enough room horizontally from the face of the deck to where the stringers will be fixed.

Once you have the height to deck measurement you can use the table below to find out which size stringer you need

How many step will I need? Explained

As explained above we have a rise of 175mm and a going of 250mm for all our stair stringers. So to calculate the number of treads (steps) you will need, we simply take the height to deck measurement and then divide this figure by 175 (rise height). We than take that final figure and subtract 1, as this final figure has given the total amount of rises and not total amount of treads.


A height of 2100 divided by 175 = 12  minus 1 = 11 treads required.

calculate the number of treads required by working out the vertical height
