Description

Product Features

1) Corrosion resistance

2) Flame retardant

The high-quality matrix resin and unique flame retardant formula endow the product with excellent flame retardant performance. Fiberglass grating products have undergone flame retardant testing by the American Society for Testing and Materials (ASTM). The flame diffusion coefficients of polyester resin, vinyl resin, and phenolic resin gratings are less than 15/10/5, and the smoke densities are less than 500/300/5, respectively

3) Lightweight and high-strength

The perfect combination of alkali free glass fiber yarn and resin endows the product with unique lightweight and high-strength characteristics. The product has a specific gravity of 1/4 of steel and is suitable for various load-bearing structures in corrosive environments.

4) Aging resistance

The product is made of high quality matrix resin and anti-aging additive, so that the product has a lasting anti-aging performance, can maintain a long gloss and sustained high strength, and has a service life of more than 20 years.

5) Designability

In addition to the flexible design performance of fiberglass, the color of the product can be customized according to customer requirements, and the external dimensions can also be cut and spliced into the size required by the customer

6) Safe and anti slip

Different surface effects make the grille have anti slip performance, with slight elasticity reducing the fatigue of workers. The double plane, groove surface, and sand surface provide anti slip performance for different usage scenarios.

7) Electrical performance

Glass fiber and high-performance resin endow the product with superior electrical performance. The penetration strength of the product can reach 10kv/mm, and there is no electric spark when metal tools resist it; The product is non-magnetic and can be safely used in anti electromagnetic and anti explosion environments.

Material Selection Plan

●Selection of resin types

Code name	Resin type	flame retardant performance	standard color	Recommended occasions for application
MP-5	Phenolic aldehyde property	The oxygen index can reach around 80	brown	Low toxicity and high flame retardancy, used in situations where fire safety is extremely important
VEFR-25	Vinyl type	Oxygen index of 28 or above	Grass green, yellow, gray, orange	In environments with severe corrosion such as acid and alkali solvents
VEFR-10	Vinyl type	Oxygen index 36 or above	Dark gray, black	In situations where high flame retardancy is required, as well as excellent acid and alkali resistance
IFR-25	Meta benzene type	Oxygen index of 28 or above	Grass green, yellow, gray	More economical than VEFR type, with excellent acid resistance, moderate alkali and solvent resistance
IFGR-30	Meta benzene food grade	Oxygen index 26	yellow	Mainly used in meat products and food processing plants
OFR-25	Ortho benzene type	Oxygen index of 28 or above	Green, yellow, gray	General acid and alkali resistant environment
CDR	Ortho benzene type	Oxygen index of 28 or above	Grass green, yellow, gray	More economical than OFR-25, without flame retardant requirements

●Selected glass fiber roving type

Code name	Types of Roving	Recommended occasions for use
E	Alkali free roving	Applied to occasions with high strength requirements and high corrosion resistance
C	Medium alkali roving	More economical than E, but slightly lower, with better acid resistance

●Selected packing type

Code name	Type of yarn filling	Recommended occasions for use
ATH	aluminum hydroxide	Flame retardant, smoke emitting, corrosion-resistant applications
CAO	calcium carbonate	More economical than ATH, without flame retardant requirements
PR	No fillers, pure resin	Used in high corrosion resistant environments

Grid Surface Selection Scheme

Manufacturing Process

Fiberglass molded grating is made by cross weaving glass fibers and integral molding with resin casting
1. The interweaving of glass fibers and the thorough infiltration of resin make the grid machine highly resistant to corrosion.
2. The cross composite structure of glass fiber and resin evenly distributes the load, which is helpful for the uniform stress distribution of the grid type, installation, and installation support structure. Enhance load-bearing capacity.
3. Wear resistant and anti slip surface: The concave surface of the grille gives it anti slip performance, and the sand surface has better anti slip effect.
4. The glossy and italicized surface of the grille gives it a self-cleaning effect.
