Natatec GPM Grating
How to Buy | Literature & Technical Information

The unique design of Natatec GPM grating means fast flow of water through the special flow control slots that are permanently machined into the grating.

GPM Grating is custom fabricated from a marine-grade polymer and is environmentally stabilized to withstand the harshest aquatic conditions. It will not rot, discolor or delaminate. Even repeated blows from a heavy hammer will not break GPM grating.
A low-maintenance finish, repair and refinishing due to weathering and deterioration is eliminated, and cleaning is easy. GPM Grating has a slip-resistant matte finish on both sides to hide scuffs and scratches.
Features and Benefits that make Natatec GPM grating the right choice:
  • Environmentally stabilized for harsh sun and tough aquatic environments. Totally safe and non-toxic. Natare GPM grating and surfacing is made entirely from FDA- and USDA-approved materials. No reaction with pool chemicals
  • Will not crack, flake, separate, rot, swell, splinter or delaminate when exposed to aggressive water conditions.
  • Precise tolerances ensure consistent color, thickness and density
  • Available in eight standard colors and custom colors. Durable matte-textured surface on both sides.
  • Colorfast and easy to clean. Never needs refinishing
  • Permanent slip-resistant surface.


Natatec GPM Grating and Decking is simply the best grating or decking system available.

Ideal for pool surrounds, gutters, platforms, decking or environments that require a durable, virtually indestructible surface.
