This is Astral’s Reversible Modular Transversal Grating for Curves in 13-3/16 inch width made of molded UV resistant polypropylene. This item is sold per foot. The Modular Transversal Grating will flex out like a fan to go around curves. It is made of polypropylene which is stabilized against UV rays. Each square snaps together on the central spine allowing flexibility between the tiles.
Please note: It is necessary to construct the channel 5mm wider than the grating itself to allow for easy removal and allow for expansion.
