NEMA Grade Laminates

Lamitex ® grade materials that meet NEMA specifications are used in over 60 markets and hundreds of applications annually.

We are able to supply small and large quantities of sheets, rods, tubes (round/square/rectangular), angles, and custom fabricated parts. Our wide range of composites make it easy for us to designate the best fit for your composite insulation or bearing requirements.

Below you will find a cross-reference table containing some of the Lamitex ® sheet materials that meet NEMA specifications.
