Perma-Trench Series is the most widely used trench drain product offered. The channel is constructed from High Density Polyethylene (HDPE). HDPE is an impact resistant, lightweight material with a low water absorption that makes it ideal for trench drain applications.
In addition, HDPE channels are extremely resistant to acids, alcohols and bases. Its ability to withstand the attack of industrial chemicals and cleaners allows it to be effectively sterilized and, therefore, makes it an ideal material choice for laboratory applications.
