Custom Steel Stair Stringers

LevelMaster stair stringers (pair) are a superior product that has been expertly designed to stand the test of time. All stringers are hot dip galvanised after fabrication, resulting in corrosion protection inside and out. Build your stairs right the first time, do it with LevelMaster.

Custom Stair Stringers: Also Known As

Custom stair stringers are also referred to as:

  • Made-to-measure stair stringers – built to a specific rise and going rather than a standard size
  • Bespoke stringers – a term used interchangeably with custom stringers
  • Non-standard stringers – describes any stringer built outside the usual off-the-shelf rise and going

Custom Stair Stringers

Special rise requirements

If you have special rise requirements, we can also supply individual stair tread brackets or manufacture a set of custom stair stringers (on the left is a set of one of our custom stringers). Custom stringers are available in HDG and Duragal for different corrosion requirements. We also have hardwood, merbau, aluminum, and metal step treads as well as the bolts to suit. You can purchase your stringers, treads and bolts in 1 order.

When Do You Need a Custom Stair Stringer?

A custom stair stringer is generally needed when your site doesn’t match the standard 175mm rise and 250mm going that a standard LevelMaster stringer is built to. Common situations include:

– A total height to deck that falls between standard tread-pair increments
– Restricted rise or going due to limited space or an existing structure
-A specific corrosion environment requiring a particular finish, such as coastal Duragal or HDG
-A non-standard material choice, such as aluminium or a specific hardwood tread

LevelMaster Steel Stair Stringers

stairs Levelmaster Australia

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.
 

Where your project falls outside these standard measurements, a custom stair stringer can be manufactured to suit.

 

Three types of connections for stair stringers

LevelMaster stair stringers are available with three different bases for installation. When purchasing our stringers you will have the option of bolting them down onto an existing pad or casting them into concrete. Both of these options are free with the stringers, do not require any cutting of steel and are adjustable. A third option is to have a landing to landing connection, this is for any stringer running from one floor/deck to another. The landing to landing connectors are sold as a sperate item with more information click below

Frequently Asked Questions

How is a custom stair stringer different from a standard one?
A standard LevelMaster stringer is built to a 175mm rise and 250mm going. A custom stair stringer is manufactured to a different rise, going, or overall size to suit a specific site.

Can I get a custom stringer in a specific finish?
Yes. Custom stringers are available in HDG (hot-dip galvanised) or Duragal, depending on the corrosion protection your site requires.

Do custom stair stringers cost more than standard stringers?
Custom manufacturing generally costs more than an off-the-shelf standard stringer, since it’s built specifically for your measurements rather than to a pre-set size. Contact us for a quote based on your specific requirements.

Can I order custom stringers, treads, and bolts together?
Yes. Stringers, treads and bolts can all be purchased in one order.
