Stair Treads

The Treadwell range of FRP Stair Treads includes both open surface and closed surface options and a range of surface patterns, colour and leading edge nosing options. All GratEX® and MoultrEX® premium and standard Stair Tread options are moulded with the solid leading edge nosing as an integrated single stage operation. This increases the rigidity and durability of the entire leading edge ensuring reliable performance in high traffic scenarios. All the treads with abrasive leading edge nosings are manufactured to conform to AS 1657 - 2018.

Traditionally, stringer bracket assemblies are made from metallic materials which require corrosion inhibiting coatings to ensure satisfactory life span. It is typical for stair tread mounting brackets to be drilled in situ after this coating has been applied, thus compromising the integrity of this first line of defense against corrosion. It is also common for stringer brackets to be constructed of lighter walled material than other adjacent componentry such as stringers.

Our stair tread kits have been adopted as a superior replacement for originally specified equipment in many instances as well as having been chosen as a long life and cost saving alternative to metallic systems in numerous new plants. Tread kits are available in all resin systems and are supplied standard with four M-Clips. Treads can be supplied assembled ready for installation or ready for assembly onsite. Likewise, stringer support brackets can be supplied with pre-drilled mounting holes if specified.

The GratEX® and MoultrEX® Stair Tread nosings are typically stocked in colours that contrast by 30% with the primary tread colour, as per AS 1657 - 2018. This ensures maximum visual awareness of the stair treads forward edge for the public utilising the stairways and consequently enhancing the OHS safety ratings.

Treadwell recommends that leading edge nosings are specified when ordering GratEX® and MoultrEX® Stair Treads as the safety risks associated with elevated work areas or walkways are significantly increased without them.

NOTE: A bearing surface of at least 40mm is recommended at either side of GratEX® and MoultrEX® Stair Treads. Compliance with AS 1657 - 2018 requires a tread depth of > 225mm.

GratEX® landings are also available as a part of Treadwell’s extensive range of offerings. GratEX® landings combine the lasting non-slip properties, the resilience to corrosion and the proven long term cost advantages of GratEX® stair treads with the durable nature of GratEX® grating. These landings are custom made for each and every application, greatly enhance visibility and reduce the wear commonly seen on landings immensely.
