FRP Grating Chemical Resistance Guide & Resin Selection
Choosing the Right Resin: Ortho vs. Iso vs. Vinyl EsterDetailed Chemical Resistance Chart (Max. Service Temp. °C)
NA-ME FRP Gratings provide exceptional resistance against a wide range of corrosive chemicals, including sulfuric acid, hydrochloric acid, sodium hydroxide, and various solvents. Unlike traditional metal flooring, our gratings do not rust or degrade when exposed to aggressive industrial fluids. To ensure optimal performance for your specific application, we offer alternative resin systems such as Orthophthalic (standard use), Isophthalic (industrial grade), and Vinyl Ester (maximum chemical resistance). Trust NA-ME for durable, maintenance-free flooring solutions that withstand extreme chemical exposure.
Preliminary compatibility guide
This table is intended only for preliminary material screening. Final suitability must be confirmed in writing with the NA-ME technical team. Performance depends on the exact resin formulation, chemical concentration, temperature, exposure duration, mechanical stress and cleaning conditions. Do not use this table as a project approval or warranty.
