WIRECLOTH: needs a cambered surface to stretch over to ensure wires tighten to what we call DRUM HEAD TIGHT.

POLYURETHANE AND RUBBER PANELS, 2'X2' OR 2' X 4' OR 6'X2'

these typically utilize a steel snap in grid design. The grid welds onto the flat deck surface of a vib screen deck....after the longitudinal rails (which create the camber for wirecloth) are removed.

THESE types of screening media DO NOT NEED TO BE STRETCHED like wirecloth. they just need to be held down, at sides with HOLD DOWN BARS AND some times with intermediate jbolts or other bolting types to stop from flexing, or slapping and BREAKING THE support deck below.

.................

If you want to try POLYURETHANE or RUBBER on a cambered deck to see if it will work for you. I recommend, buy one with METAL REINFORCED HOOKS bolted onto it, take wirecloth out, install the POLY or RUBBER section. RUN FOR a week, one section only at feed end position number one, whilst leaving the rest of the deck with wirecloth still in. If it works, convert entire deck to flat deck configuration if NOT, put wirecloth back in.

...................

TRELLSTEP urethane: this style is neat. Top panel, snaps over lead edge of second panel down, then 2nd to 3rd....etc, all the way down. Step Deck CONFIG is great concept, material passes over edge, cascades or tumbles over the step, exposing all surfaces to the openings and repeats all the way down. Makes for efficient screening. This style requires special cross members with 1" high risers to accept the snap edge of the poly.

.......................

WEDGEWIRE: These panels are set in, ontop of the support deck, cut to size of width of inside of the sideplates. Then, a wooden block is banged in ONTOP of the Stainless steel wedgewire at the edges of the sideplate, down the length. The wooden wedges are driven IN , til they tighten or friction fit to the underside of a keeper plate on the inside of the sideplate and hold the panels in TIGHT.

.................

material RUNS more nicely, more even and uniform on the BED DEPTH going down the deck on a FLAT SURFACE used for poly and rubber panels. Unlike WIRECLOTH, you do not have material ganging up on the sides, due to the cambered deck design, WHICH in fact causes MINI SURGE LOADS or bed depth too deep issues AT the sides of the wirecloth sections. NOT A GOOD THING.

Hoping this takes the tension out of your situation.
