FRP molded grating surface choics:
Flat Top
Standard Grit
Fine Grit
Concave Finish
● Flat Top Molded grating ground to a smooth flat surface
●Standard Grit Standard grit for non slip protection
●Cancave Surface Natural finish with slight concave profile on load bars
● Fine grit Surface A fine grit surface finish which requires the surface to be ground smooth to remove the concave finish before applying fine sand.
FRP Resins Systems Choices:
Phenolic resin (Type P): The best choice for applications requiring max fire retardant and low smoke emissions such as oil refineries, steel factories, and pier decks.
Vinyl Ester (Type V): withstand the strict chemical environments used for chemical, waste treatment, and foundry plants.
Isophthalic resin (Type I): Type I is a premium isophthalic polyester resin. It is a popular choice for most applications due to its good corrosion resistance properties and relative low cost. This type of resin is most commonly used in applications where there is a possibility of a splash or spill of harsh chemicals.
General Purpose Orthothphalic resin (Type O): economic alternatives to vinyl ester and isophthalic resins products.
Food Grade Isophthalic resin (Type F): Ideally suitable for food and beverage industry factories which are exposed to strict clean environments.
Epoxy Resin(Type E):offer very high mechanical properties and fatigue resistance, taking the advantages of other resins. Mold costs are similar to PE and VE, but material costs are higher.

According to the different environments and applications, chosen different resins, we also could provide some advices!
CASE STUDIES
SINOGRATES@FRP grating is a hand lay-up composite of unsaturated resin and continuous fiberglass roving that is thoroughly wetted out and woven through an open mould.Our FRP grating is composed of 30%-35% fiberglass roving and 40% unsaturated resin ,Meanwhile,fire retardant blockers (ASTM-E84 )and UV protection blockers will be added to mixed materials during manufacturing.
When it comes to industrail,marine, or commercial environment, safety and durability are non-negotiable . FRP grating with grit surface is specially designed to address these critical needs.
Where the grit surface grating should be used
Oil & Gas system Slip-resistant walkways on offshore rigs exposed to seawater and hydrocarbons.
Manufacturing Safe working platforms in factories with grease, coolant, or hydraulic fluid spills.
Marine Docks, gangways, and ship decks requiring traction in wet, salty conditions.
Utilities Stair treads and trench covers in water treatment plants or electrical substations.
Food & Beverage Sanitary flooring that withstands daily washdowns without degrading.
