Safe access between levels is a must when working on scaffolding. A scaffold stair tread is designed to make that possible. This blog explains what scaffold stair treads are, how they improve site safety, and more. 

What Are Scaffold Stair Treads? 

A scaffold stair tread is used when a scaffold needs access instead of ladders. It forms the step in a stair unit that workers step on when moving between levels. 

These treads are made from galvanised steel or aluminium, designed to provide grip. Some have a perforated surface to improve traction underfoot, especially in wet or muddy conditions. 

The stair system of the scaffolding is attached to the structure itself. The stair treads fit into place as part of it, forming a temporary staircase. Side rails are added for further safety. 

Different Sizes of Scaffold Stair Treads 

Common sizes include 0.9m, 1m, and 1.05 m. The size you go for depends on the scaffold design and the expected traffic. 

For instance, a 0.9m tread is best for smaller or compact scaffolds. Meanwhile, a 1m tread or 1.05m tread is better suited for larger scaffolds or areas with heavy foot traffic. 

How Stair Treads Improve Site Access 

Here’s how handy scaffold stair treads are: 

Safe access up and down the scaffold 

Workers have a more reliable option than ladders for getting from one level to another. The stair treads are wider and more stable, providing better support. 

Better grip on steps 

The holes in the tread give your shoes more to grip onto. They also let water, mud, and debris drain through, which helps stop the surface from getting too slippery. 

Makes moving tools and materials easier 

Workers can carry tools and materials with less concern about their footing. The improved traction reduces slips while giving workers support to keep loads steady. 

Scaffold Access Safety and Compliance 

Scaffold stair treads support safe access in line with Work at Height Regulations. They’re also expected to comply with relevant parts of BS EN 12811 for temporary works. 

Standard practice includes proper fitting of each tread, not just for stability but also to avoid breaches in site safety checks. Using stair tread couplers that conform to quality assurance, for one, reduces the risk of shifting under load, loosening or detaching during use. Making sure everything is fitted right also helps avoid hassle during inspections, which can lead to failed checks and delays. 

Note: Couplers are used to secure the treads to the scaffold, holding them in place to keep the stair system stable. 

Weight rating and load capacity matter too. The treads need to support the expected foot traffic and equipment without buckling or shifting. Otherwise, it could lead to safety issues or worse, injury. 

Stair Tread Maintenance 

Take a look at the treads for any damage, such as cracks, bends, or rust. These can make the tread weaker and less stable. Replace them if necessary to avoid accidents, especially in areas with heavy foot traffic or bad weather.
