Railway sleepers are made of hard, good quality, healthy trees with dense and straight fibers. All the trees used in sleeper production are cut while green before the feed water reaches the tree. Sleepers are in straight and regular form. End plates are assembled on both ends of the sleepers. Our sleepers are subjected to impregnation process with ecological creosote under high pressure against pest infestation and decaying. Impregnation process extends service life of oak sleepers for approximately 30 years. Our sleepers are produced in accordance with EN 13145 standards as adzed and unadzed, impregnated using ecological creosote.
