Zurn Z812Zurn’s fiberglass Z812 drainage system is top of the line when it comes to high volume industrial projects.  The 12" wide (OD) fiberglass channels feature a steep 1.04% slope, allowing the system to handle more flow with less debris build-up.  Corrosion-resistant and lightweight, Z812 channels come in 10' modular pieces for quick installation.

The Z812 system includes a heavy-duty steel frame, which distributes load weight from the grates into surrounding concrete.  For caustic applications, stainless steel frames complement the chemical-resistant fiberglass trench drain.
