HEAVY DUTY TRENCH
Materials: All frames and grates or lids are made in standard gray iron, meeting ASTM-A48 Class 35-B for heavy-duty use. For extra heavy-duty use or
superior durability requirements, see our ductile iron Airport and Port Grating Series on page 286.
Neenah recommends project designers avoid the use of light duty trench installations because it is likely that applications will be subjected to heavy
delivery vehicle traffic at some time. Furthermore, the use of a site could be changed to heavy duty use patterns at some unanticipated future date.
Bolted trench drain grates shall be installed grate on frame.
