FRP molded grating surface choics:
Flat Top
Standard 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
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.
Resins options guide：
| Resin Type | Resin Option | Properties | Chemmical Resistance | Fire Retardant(ASTM E84) | Products | Bespoke Colors | Max ℃ Temp |
| Type P | Phenolic | Low Smoke and Superior Fire Resistance | Very Good | Class 1, 5 or less | Molded and Pultruded | Bespoke Colors | 150℃ |
| Type V | Vinyl Ester | Superior Corrosion Resistance and Fire Retardant | Excellent | Class 1, 25 or less | Molded and Pultruded | Bespoke Colors | 95℃ |
| Type I | Isophthalic polyester | Industrial Grade Corrosion Resistance and Fire Retardant | Very Good | Class 1, 25 or less | Molded and Pultruded | Bespoke Colors | 85℃ |
| Type O | Ortho | Moderate Corrosion Resistance and Fire Retardant | Normal | Class 1, 25 or less | Molded and Pultruded | Bespoke Colors | 85℃ |
| Type F | Isophthalic polyester | Food Grade Corrosion Resistance and Fire Retardant | Very Good | Class 2, 75 or less | Molded | Brown | 85℃ |
| Type E | Epoxy | Excellent corrosion resistance and fire retardant | Excellent | Class 1, 25 or less | Pultruded | Bespoke Colors | 180℃ |

SINOGRATES@FRP MOLDED GRATING
•Light
•Insulation
•Chemical resistance
•Fire retardant
•Anti-slip surfaces
•Convenient for installation
•Low maintenance cost
•UV protection
•Dual strength
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.
FRP (Fiberglass Reinforced Plastic) MINI grating is a lightweight, corrosion-resistant grating with a smaller mesh size and shallower depth compared to standard FRP grating.
Its primary uses include:
Light-Duty Walkways such as Ideal for pedestrian areas with low to moderate foot traffic, such as catwalks, platforms, or maintenance pathways
Drainage Covers: Used in drainage systems, trenches, or channels where smaller openings prevent debris accumulation
Architectural Applications: Decorative or functional uses in landscaping, stair treads, or sunshades due to its aesthetic appeal and customization options.
