On large flumes with large pipe stubs, the danger can be even greater.  Here if an operators falls into the flume they could very well be swept out of the flume and into the downstream pipe system...a potentially fatal event.

In applications where the grating may need more support than that offered by the molded in recesses at the top of the flume, Openchannelfow installes tube supports at the inlet / outlet of the flume for the grating to sit on to provide additional support.

Fiberglass covered grating is a long-lasting, molded fiberglass floor product that combines smooth, gritted, or checker plate and molded grating manufactured with any of our resin systems. It is the ideal choice when a 100% covered flooring surface is needed. Our fiberglass covered grating is often used in loading and storage areas with high foot and cart traffic. This is where a strong, level surface is ideal, and this is why fiberglass covered grating is ideal. If offers approximately 50% higher stiffness values than that of open mesh grating, and its standard grit-top cover assures secure footing. For more on fiberglass covered grating, click here.
