PRODUCT MATERIAL: Traffic speed bumps are made of rubber material. Thickened rubber makes the lane speed bump structure more solid and stable, it will not deform under any pressure, immediately return to a stable state, and will not fade UNIQUE DESIGN: The honeycomb hole design at the bottom of the speed bump increases the compressive strength, is not easy to break or damage, and can reduce the noise generated when the tire rolls REFLECTIVE DESIGN: The speed bump is inlaid with reflective beads, which can effectively reflect light even at night or in dim light, thereby increasing the visibility of the speed bump, allowing drivers to find and slow down at a farther distance WIDE RANGE OF USES: Suitable for highways, parking lots, hospitals, home stairs, factory material handling, stairs, hotels, shopping malls, streets or other areas EASY TO INSTALL: The surface has pre-made holes for bolting to gravel, asphalt or concrete road surfaces. Multiple speed bumps can be easily connected to achieve any desired length required for various road widths
