How to choose the right demarcation stud
Demarcation done right
Demarcation studs are visual and tactile signals that mark the boundaries of a given area. Common applications include outdoor dining areas, queue lines, parking spaces and other locations where a space needs to be defined.
Choosing the right stud depends on where it will be installed, how the space is used and how visible the boundary needs to be.
What are you marking out?
The location being marked out influences several factors when choosing demarcation studs. If the area is large, like a courtyard or plaza, larger studs are often preferred to make the boundary more visible and obvious.
In more intimate settings, like a restaurant’s outdoor dining space, the area is more concentrated and specific. Smaller studs are usually opted for because they’re being viewed from closer up and can define the boundary without dominating the space. Their height and profile also matter where people and furniture need to move over them.
Commonly demarcated areas include:
- Car parking spaces
- Outdoor dining areas
- Property boundaries in the absence of a wall
- Pathways
What surface will the studs be installed into?
Demarcation studs are mostly installed into hard external surfaces such as concrete, brick, tile and stone, owing to these being common surface materials in the public realm. For these installations, a stud with a fixing pin is typically used. The installation process is the drill and resin method, which you can see in our installation guide.
They can also be installed onto wooden surfaces such as decking, using a model with a screw fixing hole. These studs are screwed directly into the timber with a suitable fixing, drilling a pilot hole where needed.
In some locations, particularly indoors, it may not be possible to drill into the underlying floor. In those circumstances, or where an installation is temporary, self-adhesive demarcation studs may be a suitable solution. Check that the adhesive is suitable for the surface and, for temporary installations, whether removal could leave residue or affect the floor finish.
Which material and finish should you choose?
Material and finish are important aspects of demarcation studs because they influence whether the studs are noticed and the boundary is understood. That’s not to say a harsh, contrasting anodised colour is always the answer either.
The key is to strike a balance between the surrounding surface and the studs themselves. LRV, or light reflectance value, is a useful way to measure tonal contrast. A difference of 30 points is commonly used as a benchmark in accessibility guidance, though the layout, lighting and requirements of the location also need to be considered.
This contrast can be achieved through the different metals themselves, including stainless steel, brass, bronze and aluminium, or through treatments like anodising aluminium in different colours. The important thing is to assess the finished stud against the surface it will sit in.
From a material perspective, 316L stainless steel is a durable, corrosion-resistant option for demanding external conditions, including coastal regions where salt exposure is a major factor. Other steels may be suitable, but Studmarc manufactures primarily in 316L stainless steel for long-term performance. It still benefits from regular cleaning and maintenance, particularly in exposed locations.
Brass and bronze are well suited to heritage locations, listed-building settings or anywhere they need to match the surrounding aesthetic. Bear in mind that brass and bronze will patina over time. This can be part of their appeal, but keeping a brighter finish requires regular care.
Aluminium is a more customisable alternative and, depending on the product and finish, can also be a cost-effective option. It can be anodised in various colours to help provide contrast or match the wider design. Check the available colours before specifying a particular finish.
Which stud profile suits the location?
The location in which the demarcation studs are going to be installed can help narrow down the choice of profiles. Where there’s going to be passing traffic, such as delivery vehicles, cyclists or wheelchair users, a flush-fitting or low-profile stud is worth considering, particularly with larger studs like a 90mm demarcation stud.
Large studs that rise above the ground can impede vehicles, wheelchair users, cyclists and pedestrians. The same consideration applies when marking out parking bays. A flat-topped stud isn’t necessarily flush with the ground, so check the installed height and whether the stud and fixing are suitable for the expected traffic.
In more intimate locations where vehicles won’t be passing over them, like outdoor dining areas, the studs will generally be smaller and there are multiple profiles to choose from. Chamfered, low-dome, flush-fitting and domed studs are available.
These profiles influence the tactility of the studs and can help reinforce the boundary through another sense. Their height and position still need to account for pedestrians, wheelchair users and the movement of tables and chairs.
Do you need plain or marked studs?
There are multiple ways to customise the stud’s surface, and this can serve a variety of purposes. Information can be engraved or printed onto the studs to provide a sense of identity or branding in line with the organisation installing them.
Markings can also explain what the studs are demarcating or who the area belongs to. For restaurants with outdoor seating, they can even define seating areas for staff reference.
A plain stud may be enough where the boundary is self-explanatory. If you’re adding wording or a design, consider the size of the stud and how close someone will need to be to read it.
How many studs will you need?
The number of studs you need depends on the length of the boundary and the spacing between them. The size of the studs and how well they contrast with the surrounding surface also influence how obvious that boundary will be.
For a straight boundary, consider 500mm centre-to-centre spacing as a starting point. This is measured from the centre of one stud to the centre of the next, rather than the clear gap between them.
Plan the corners and changes of direction first, then space the remaining studs evenly between them. Curves or more detailed layouts may need closer spacing. Before fixing, lay out a short section to check how it looks from the distance people will normally be viewing it.
For a straight run with a stud at each end:
- Measure the distance between the first and last stud centres.
- Divide that distance by your chosen spacing, using the same units.
- Round up to the next whole number and add one.
For example, a 10-metre run at 500mm centres needs 21 studs: 20 spaces, with a stud at each end.
If you’re marking out several sides, calculate each section separately and count shared corner studs only once. Any spacing specified in the project design should take priority.
