i'm engineer from miami, i like to work out and travel to the beach. i work in a furniture store, we have great parking lot speed bumps, very resistant, with a safety yellow color, quick and easy installation, work in asphalt or concrete, they're a perfect solution to slow the speed traffic.
in our store we have the best traffic control speed bumps, these speed bumps are made with high quality and very resistant material. speed bumps are great to help preventing drivers from speeding on the roads.
