Description
This 25mm flush-fit visibility stud is manufactured from 316L stainless steel and features a smooth, flat surface. Measuring 25mm in diameter and 4mm in height, it can be recessed into a surface to create a flush visual marker or installed slightly proud where additional tactility is required.
Its flat face can be engraved with logos, symbols, numbers or other markings to communicate information or identify a defined area. When specified with suitable visual contrast, the stud may also help partially sighted pedestrians recognise a boundary or change in level.
This product is not intended to recreate prescribed tactile paving patterns, such as blister paving at pedestrian crossings or corduroy warning surfaces near steps. Read more about what makes tactile studs and strips compliant.
Material Information
The stud is manufactured from corrosion-resistant 316L marine-grade stainless steel for reliable long-term performance in internal and external environments.
The addition of molybdenum gives 316L stainless steel greater resistance to corrosion than commonly used grades such as 304, particularly in exposed locations where the stud may encounter moisture, salts or other environmental contaminants.
Compare stainless steel with aluminium, brass, bronze and other available options in our guide to tactile stud and strip materials.
Design
The flush-fit visibility stud features a smooth, flat face with straight edges. Its 4mm-deep head allows it to be recessed flush with the surrounding surface or installed slightly proud, depending on the required visual and tactile effect.
The 25mm face can be engraved with:
- Logos and branding
- Symbols and directional markers
- Numbers or reference codes
- Short wording or identification marks
Its machine-polished finish provides a bright appearance, although the visibility achieved will depend on the contrast with the surrounding surface and the lighting conditions within the installation area.
Application
These studs are suitable for:
- Inset stair-edge visibility markers where specified
- Marking boundaries and designated areas
- Identifying routes or changes within a surface
- Displaying engraved symbols, numbers or branding
- Project-specific visual or tactile marking
Where the purpose is to define a boundary rather than create a prescribed warning surface, read about the difference between demarcation studs and tactile studs.
Installation
This stud is installed using the drill-and-resin method:
- Mark the required position.
- Drill a hole or recess suitable for the fixing and required installed height.
- Remove all dust and debris from the hole.
- Apply a suitable epoxy resin.
- Insert the stud and remove any excess resin.
- Allow the resin to cure fully before reopening the area to traffic.
Curing times vary between products and environmental conditions, so always follow the resin manufacturer’s instructions.
Installation equipment required: Drill, suitable drill bit, push pump, epoxy resin and applicator gun.
