? Frequently asked questions

How to choose the correct height of a speed bump?
The height of the speed bump is chosen based on the speed at which you want to restrict traffic. Generally, bumps with a height of 7 cm are intended to reduce speed to below 20-30 km/h (used in driveways or parking lots). Those of 5 cm are ideal for thresholds of 30-40 km/h (residential streets), while lower models, of 3 cm, allow transit at speeds of up to 40-50 km/h.
What is the difference between rubber and plastic speed bumps?
Rubber speed bumps are quieter, absorb shocks better, and protect the suspension of vehicles, making them ideal for residential areas and private parking. Rigid plastic (or composite) bumps are harder, offer very high mechanical resistance to weight, and are recommended in areas with heavy traffic or where commercial vehicles frequently transit.
How are these speed bumps installed on the roadway?
Installation is extremely simple and quick. The bumps are made up of modular elements (middle pieces and end pieces) that interlock on the asphalt. Each piece is equipped with holes through which special anchors and screws are inserted, anchoring directly into the asphalt or concrete.
Are street speed bumps visible at night?
Yes, absolutely. All speed bumps in our range are made in strongly contrasting colors (black and yellow) and are equipped with reflective films or incorporated cat's eyes. These elements capture and return the light from headlights, ensuring excellent visibility at night, in rain, or fog.
What accessories are needed for the complete installation of a speed bump?
In addition to the yellow and black modular pieces that make up the length of the road, you need end caps (for aesthetic finishing and protecting the edges), special fixing screws and anchors (suitable for asphalt or concrete), and ideally, the installation of a warning road sign before the bump.
