Can these be cut at all?
Yes you can cut to fit to size on your installation. However these do have to be cut on site, we can not do it at our location due to liability reasoning, and of course you want to measure perfectly on your site in case things change.
How do these fasten down?
This particular grating does not have fasteners. However it has a snap in place system on the edging of the grating. So if you have one of our 4 inch channels, or a 4 inch channel that you are retrofitting, then these will snap into place nicely. The snap connections can also be bent of course for a little wider connection if needed also.
What is the GPM (gallon per minute) rating on this grating?
The GPM on this grating is 65 gallons per minute.
How strong is this grating?
This is an A Class rated system for VERY light pedestrian traffic only.
Will this brass grating have corrosion issues?
This is 100% brass, so basic corrosion would not happen, so perfect in those areas where you want it to last. Brass will age over time, but wont have rust spots like your steel, or iron would.
