Steel STAIR STRINGERS


Inground and OnConcrete/Bolt Down style Stair Stringers in both Fully Hot Dip Galvanised and Duragal-Plus Pre-Galv finish are kept IN STOCK for priority dispatch Australia wide or collect at our Brisbane Depot. Landing to Landing and
Side Fix Top Stringers are generally made to order, however small quantities of these Step Stringers are also held In Stock. Pricing Table below.

Door to Door Delivery Australia Wide Available, Rates shown below.

Quality Steel Stair Stringers: Our Engineer Designed Steel Stair Stringers, up to 17 Steps (18 Risers), are manufactured to exacting standards, in our Brisbane Factory, from first grade Australian Made Steel. Standard Stringers are fabricated at an Angle of 35 degrees to a Rise of 175mm and a Going of 250mm.

Non-Standard Custom Stair Stringers, those with different Rise or Goings, are all able to be manufactured to suit your requirements. Contact Us to receive a quotation on your specific requirements.

Scott Metals Standard Stringers, are Designed and Engineered for both Internal or External uses in Residential and Commercial applications. In Residential applications the Stringers can clear span up to 17 steps (18 Risers) when using Aluminium Step Treads or Timber Step Treads. This means NO support post under the Stringers is required, allowing more versatility in the installation and giving an aesthetically pleasing appearance.

The Standard Stringers are constructed to suit minimum 50mm thick step treads in order to achieve a maximum gap of 125mm between the treads. We supply Aluminium Step Treads, and Timber Step Treads, all are compliant with codes and standards within the Australian Building industry.

What's Included: Stair Stringers, generally sold as a pair, but also available individually, come ready to install, complete with top hanger brackets, riser brackets and a choice of footing configurations: Inground, OnConcrete/Bolt Down or Landing to Landing. Pictures, drawings and detailed information below.

Duragal-Plus: At Scott Metals we use Australian Made Steel 100 x 50 x 3.0mm Duragal-Plus RHS in the manufacture of our Stringers up to 15 Steps. This product is a pre-galvanised, inside and out, grade AS1163 - 450PLUS material. The total coating thickness of Duragal-Plus pre-galvanised sections is twice that of any other product currently available. On Duragal-Plus Stringers all the welds and stair riser brackets are shop prime coated with zinc rich Cold Galvanised Paint after fabrication. For added protection, after purchase, we recommend the use of a quality top coating.

Hot Dip Galvanised: Should you require extra protection from the elements, then we recommend using Hot Dip Galvanised Stair Stringers. Hot Dip Galvanising is a process where the stringer, after manufacture, is completely immersed in molten zinc. This thick metallic zinc coating, completely covers the stringer surface, inside and out, providing a superior corrosion resistant finish.

16 and 17 Step Stair Stringers are fabricated from 100 x 50 x 5.0mm RHS and are then Hot Dipped Galvanised to exacting Australian Standards. 16 step and 17 step stringers are only stocked in the Hot Dipped Galvanised finish. Because of the heavy duty RHS used in the manufacture of 16 and 17 step stringers, a central support post is NOT required for residential applications, when installed using Timber or Aluminium Treads.

For information, dimensions and drawings on the Riser Brackets, Hanger Plates, Bolt-On Stair Kits, How Many Steps you require, How Far Out will the Stringer base be from the landing and Australia Wide Delivery rates see below.

Design: Our Stair Stringers, used Internally or Externally, are designed for residential applications with a clear span up to 17 steps (18 Risers) when installed with Aluminium Step Treads or Timber Step Treads to a maximum of 1200mm tread width per pair. For wider tread spans a third central stringer or more must be used. If an alternative rise and going to our standard 175mm Rise and 250 Going, refer to and check the Engineers Details and Installation Table as a support posts maybe required. Otherwise, for a small increase in cost, the Stringers can be manufactured using a thicker RHS if a clear span is required.

Supporting posts or the fabrication using thicker RHS may also be required when the Stair Stringers are used in commercial applications. For these installations please check the Engineers Details and Installation Table.

After installation, if the Stair Stringers tend to vibrate, flex or spring, then we recommend the fitting of a centrally located post under each Stringer Rail.

Special 'one off' Stringers, those with PFC Channel Rails, Mono Stringers, Curved Stringers, etc, are all able to be fabricated. However, the design of these special stringers is not done by Scott Metals. A Structural Engineer is required to prepare and certify these stringers. The relevant drawings need to be supplied to us prior to quoting and or manufacture.

Engineer Approved: Scott Metals Stair Stringers are Engineer Approved and Certified to comply with all relevant Australian Standard Building Codes. Form 15 available after purchase if required. Engineers Details and Installation Table.

Note: To comply with the current Building Code of Australia, the Stringer “rise” MUST be consistent, including the first step and last step up to the landing. The ground level may need to be built up or excavated to achieve this.

Delivery: Steel Stair Stringers can be delivered Door to Door Australia wide.

INGROUND STAIR STRINGERS

The Inground (See Photo) foot style is the most popular form of Stair Stringer. After bolting the top hanger brackets into place, the base of the Stair Stringer is concreted into a suitable footing in the ground. The leg on the stringer is approximately 300mm long, giving ample anchorage into a concrete footing.
Standard Inground Stringers are IN STOCK in either fully Hot Dip Galvanised and Duragal-Plus finish, for priority dispatch or collection from our Brisbane Depot. Engineers Detail and Installation Table for more information.
Alternative Side Fix Top Stringers also manufactured. Pricing Table below.



ONCONCRETE / Bolt Down STAIR STRINGERS

For OnConcrete / Bolt Down (See Photo) applications the legs of an inground style Stair Stringer are cut to the desired length, next a Bolt-On Stair Kit bracket is screwed to each leg. The Stair Stringer legs are then anchor bolted down into place. A Bolt-on Stair Kit consists of 2 hot dip galvanised angle brackets and tek screws for fixing to the legs. Onconcrete/Bolt Down Stringers cost $15.00 per pair more than a standard pair of Stair Stringers for the Bolt-On Stair Kit.
Onconcrete/Bolt Down Stringers are IN STOCK in either fully Hot Dip Galvanised and Duragal-Plus finish, for priority dispatch or collection from our Brisbane Depot. Engineers Detail and Installation Table for more information.
Alternative Side Fix Top Stringers also manufactured. Pricing Table below.




LANDING TO LANDING STAIR STRINGERS
A Landing to Landing (See Photo) setup is also available. This type of Stair Stringer is fabricated to order. Duragal-Plus Landing to Landing Stringers are available within 24 hours and Hot Dip Galvanised Stringers require a few days more. Small quantities of Landing to Landing Stringers are IN STOCK, please check when ordering. We recommend that this type of Stair Stringer be purchased prior to erecting the landing to ensure an exact fit. Landing to Landing Stringers cost $20.00 per pair more than a Standard pair of Steel Stair Stringers. Alternative Side Fix Top Stringers also manufactured. Pricing Table below.



STAIR RISER BRACKETS

The Riser Brackets used are pre-drilled, with 2 slotted holes 11 x 18mm @ 150mm centres, to match all popular Aluminium and Concrete Step Treads on the market. We recommend and supply Aluminium Stair Treads as they are non-slip and low in maintenance. We also stock and supply 250 x 55mm hardwood Timber Step Treads.

Step Tread Riser Brackets, raw black steel, are also sold separately, ($3.50 ea Inc GST), for those wanting to fabricate their own stringers. 65 x 10mm Galvanised Cup Head nuts and bolts are available ($1.20 ea Inc GST) for fixing timber treads to the Step Tread Riser Brackets.
TOP HANGER PLATE BRACKETS

The Top Hanger Brackets used are pre-drilled, with 2 @ 14mm holes @ 50mm centres. They are fabricated from 50 x 6mm Flat Bar. When welded to the Stringer RHS they protrude 180mm above the RHS. The Top Hanger Brackets, in raw black steel, can also be bought separately, ($5.50 ea Inc GST), for those wanting to manufacture their own stringers.

Alternative Side Fix Top Hanger Brackets are also available, see image below. ($5.50 ea Inc GST).

BOLT-ON STAIR KIT

A Bolt-On Stair Kit ($15.00 ea Inc GST) is used with OnConcrete/Bolt Down Stair Stringers. The Bolt-On Stair Kit consists of 2 Hot Dip Galvanised Angle Brackets and Tek Screws for fixing to the bottom of the Stringer Legs. The Angle Brackets, 55 x 80 and 90mm long, are pre-drilled with 3 @ 6mm Holes for the Tek Screws and also
2 @ 14mm Holes for the Anchor Bolts.

Kit includes 2 Galvanised Brackets & 6 Tek Screws



HOW MANY STEPS?

How do you calculate the steps you need on your stringer?

Simply measure the height from the top of the landing to the ground directly below, divide this length by 175 rounding to the nearest whole number and deduct 1 for the top landing.

Example: Height = 2415 ÷ 175 = 13.8 (14) less 1 = 13 Steps (14 Risers)

See the Pricing Table below for further assistance.

HOW FAR OUT WILL THE STRINGER GO?

How far out will the stringer be?

Simply multiply the number of steps by 250mm (this being the going of each step) and deduct 175. The result equals the distance from the landing to the centre of the hole required for concreting the stringers into the ground.

(No. of Steps x 250) - 175mm = Centre of Hole
