We are manufacturing high quality pe road barriers in two different technologies: rotational moulding and blow moulding here in Turkey. Blow moulded barriers (SYB coded) are for massive production and rotational molded barriers (RYB coded) are slightly more expensive, because they are thicker and their production process is longer. We also make molds in our facility. So if you want any different dimension, please let us know. I would be happy to provide you any further info. Awating to hear your comments and hope for future collaboration.
