Trenchcoat protective film is laminated to the inside and outside of corrugated steel pipe to provide a corrosion and abrasion barrier against acids, salts, and alkalis in storm drains and culvert systems. It is able to withstand sandy clay runoff and gravel bed loads without losing adhesion to metal. Its light weight makes it easy to handle and install. Dow Performance Plastics. www.dow.com
