Driveways, gate and barrier protection, pedestrian areas and squares where vehicle access needs to be restricted unobtrusively.
Several Semi bollards set in a row form a discreet but clear barrier between pedestrian and traffic zones.
Concrete bollards are heavy, so they are usually simply placed in position, and the stone chip finish goes well with concrete benches, planters and paving blocks. Metal bollards are slimmer, suit narrower spaces and are fixed to the base. Choose according to the space available and the style of other outdoor furniture.
Usually not – concrete bollards stand stably thanks to their weight and are hard to move by hand. It is enough to place them on a level, firm base. The exact weight of each model is stated in the product's technical data.
Depending on the model, a metal bollard can be extended and set in concrete, bolted to the paving with a flange, or mounted with a flange under the paving. In newly laid paving, the set-in-concrete version is the most reliable. If the surface is already in place and you do not want to break it up, choose a bolt-down bollard.
Low bollards suit the edges of lawns and flower beds – they mark the boundary without dominating the surroundings. Taller bollards are more visible to drivers and do not disappear in a snowdrift. At crossings and junctions, choose a height at which the bollard does not obscure children and traffic signs.
Choose the gaps so that pedestrians, pushchairs and wheelchairs can pass through comfortably, but a car cannot enter. It is worth agreeing the exact distances with the site project or the municipality. If needed, the bollards can be linked with a chain.
Some metal bollards have a cap with a reflective coating that shines in headlights and shows where the boundary is. A coloured cap can also highlight the purpose of the zone. This is especially useful near schools, crossings and car parks.
Yes, chain loops can be ordered for metal bollards on request. This creates a temporary or permanent barrier, for example to block a driveway. Specify whether you need loops when ordering.
