Description
Generally, stringer bracket assemblies are made from metal which require corrosion inhibiting coatings occasionally to slightly extend its life span. It is typical for stair tread mounting brackets to be drilled in situ after this coating has been applied, thus lowering the first line of defense against corrosion. It is also common for stringer brackets to be constructed of lighter walled material than other adjacent componentry.
Our stair tread kits are 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 for numerous uses. All EX-Series® resin systems can be applied to our Stair Treads which are supplied standard with four M-Clips. Treads can be supplied assembled ready for installation or dispatched ready for assembly onsite. Likewise, stringer support brackets can be supplied with pre-drilled mounting holes if needed.
The GratEX® and MoultrEX® Stair Tread nosings are typically stocked in colours that contrast the primary tread colour by 30% as per AS 1657 – 2018. This ensures maximum visual awareness of the stair treads forward edge for the stairways and consequently improving OHS safety ratings.
To significantly reduce the safety risks associated with elevated work areas or walkways, Treadwell recommends that leading edge nosings are specified when ordering GratEX® and MoultrEX® Stair Treads.
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.
