Molded FRP grating isophthalic resin is more resistant to corrosion than orthophthalic resin grating. The oxygen index of the isophthalic FRP molded grating is 28 or above, and the oxygen index of the isophthalic food-grade FRP molded grating is 26, which is mainly used in meat and food processing plants.
The price is directly proportional to the corrosion resistance, so the resin type should be selected according to the corrosive medium of the application environment. There are three commonly used resin types for FRP molded gratings: Orthophthalic, Isophthalic and Vinyl:

Code	Resin Type	Standard Color	Application	Price
V-CF	Vinyl	Grass, Green, Yellow, Gray, Orange	Chemical use: Excellent corrosion resistance, acid, alkali, salt, solvent resistance, long-term use temperature: -50~110℃	＞Isophthalic, Orthophthalic
V-CR	Vinyl	Dark Gray, Black	Used in environment that requires excellent flame retardant and excellent corrosion resistance	＞Isophthalic, Orthophthalic
I-IF	Isophthalic	Grass Green, Yellow, Gray	Mostly used in the municipal field, good corrosion resistance, can withstand various salts of medium-concentration inorganic acid and alkali, long-term use temperature: -50~90℃	＜Vinyl
I-FF	Isophthalic Food Grade	Yellow, Light Grey	Mainly Used In Meat And Food Processing Plants	＜Vinyl
O-AF	Orthophthalic	Green, Grey, Yellow	General corrosion resistance, resistant to atmospheric aging, seawater corrosion, etc., long-term use temperature: -50~60℃	＜Isophthalic
O-AN	Orthophthalic	Grass Green, Yellow, Gray	No Flame Retardant Requirements	＜O-AF

Q1: How do you ensure the quality of FRP products?

A: All products are manufactured in our own factory under strict ISO-based quality control. We perform raw material testing, process monitoring, and final inspection to ensure every panel meets strength, durability, and corrosion-resistance requirements.

Q2: Where can FRP products be used?

FRP products are ideal for chemical plants, wastewater facilities, offshore platforms, walkways, platforms, stairs, and other areas that require corrosion resistance, lightweight structure, and long service life.

Q3: Do you provide after-sales support?

Yes. We provide clear documentation, installation guidelines (if needed), and technical support. If any quality issue is confirmed after delivery, we offer replacement, rework, or other agreed solutions.

Q4: Can you help with project-specific requirements?

Absolutely. Our team can suggest the right resin system, grating type, and surface finish for your application, and provide drawings or design assistance to ensure project success.
