Fabricating new screens for deck and cockpit drains

Jeff, what is the material you used for the screen and where did you get it? I still use "Hayward Pool Products. SP1Q19BA. Cycolac grate and screws" but I break 1-2 a year and have always wanted some kind of stainless. They Haywards are apparently too thick to stamp out in stainless, however, whatever you are putting in here could be covered with the Haywards and maybe they wouldn't break so easily. Or a person could stack a set of not-too-thick stainless stamped-out fittings to get the strength needed.

Rolf, Pligrim's plastic screens were also cracked. I found the material pictured above in a scrap metal pile at the boat yard. It amazes me what boaters (especially high dollar power boat crowd) will throw away. I believe the material is 1/16" thick perforated aluminum sheet available from McMaster-Carr (here is a link - McMaster-Carr Perforated Sheets). Unfortunately it looks like this material is only available in 36" X 40" sheets that cost over $350. They also sell stainless perforated sheets, but that would be very difficult to cut to shape.

These have been installed for right at one year. I've had no issues with them in that time.

Before I discovered this material, I was considering using 1/4" starboard or 1/8" FRP sheet for the screens. Cut the material to shape and then drill 3/16" holes in the piece.
