SilcaGrate’ssecret is the hexagon
Stacks Image 644
SilcaGrate™ is so strong, it meets or exceeds both residential and commercial building codes.
SilcaGrate™ is a 16” x 18” honeycombed tray made of durable 1 1/2” thick engineered polymer which is screwed directly to the top of the floor joists.
Each SilcaGrate™ grid covers two square feet. It is UV stable and easily cut to form. Its installation is as easy as putting six screws into floor joists spaced 16” on center. Its strong hexagonal cells provide a supportive sub-structure for elevated areas as well as ground applications.
The unprecedented strength results from the design of the 2” diameter honeycombs which offer 360 degrees of solid support, giving you considerably more muscle underneath your surface materials. These hexagonal cells provide support every two inches in all directions. Compare that to lumber pieces in traditional applications which typically span 16” to 24” between joists and only offer bi-lateral support.
It’s easy to see how SilcaGrate™ Grate can provide a superior level of
strength, giving you surface options you never thought possible.
