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.

The picture bellow illustrates the rise and going of our stair stringers.

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 and the cost.

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.

Example:

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

Certification Requirements

The certification requirements, for staircase construction and install in class 1 and 10 buildings, comes from the National Construction Code and Australian Standard AS1657.

Why LevelMaster stringers?

We have designed our stringers to be compatible, without any modification, for both ‘bolt down’ and ‘concrete in’ fixings. This gives you two great advantages, first you can install bolt down stringers without damaging the hot dipped galvanised coating, and also allows you to change your mind and swap the feet at any time of the order. Our stair stringers are sold in pairs (you need 2 stringers per staircase) however treads over 1300mm in length require an extra stringer for support. Refer to our engineering documents. 

We take pride in all products and ensure the highest standards in manufacturing. When you buy LevelMaster products, you can always trust that you are buying the best in the business.
