As everyone knows, FRP grating has corrosion-resistant acteristic that carbon steel cant be reached,it was originally developed in response to the harsh conditions which require products that can withstand corrosive chemicals, high temperatures, and heavy load.
HIGOAL has made repeated tests on over 50 different chemicals as detailed as possible. However, since chemicals of different brands vary greatly, users still has to perform repeated, careful tests in their own environment. This guide is provided as a guide to the use and application and is not or does not represent a specific warranty of the product or its performance. The designer or user must determine the suitability of this product for a specific application.
