Polyethylene Culverts

HDPE (High-Density Polyethylene) Culverts are also referred to as Black Plastic Culverts.  This culverts come in sizes from 4" to 60" inside diameter and twenty (20) feet long.  In sizes 4" - 12" we have the single walled (corrugated inside and out) and in sizes 6" - 60" we have the double walled (smooth inside and corrugated outside).  These culverts will never rust or corrode.  Generally we keep in stock approximately 1000' of each size 12" through 24" and approximately 400' of all the other sizes.
