Detail Information

Fiberglass Reinforced Plastic 25mm ASTM D635 FRP Grating

ASTM D635 Industrial Fiberglass Reinforced Plastic Grating

FRP Grating Panels are designed to provide long, maintenance- free service life in corrosive industrial environments.

They meet stringent weather, corrosion, and fire-resistance requirements. Engineered resins provide a high resistance

to attack from acids, alkali, solvents, and 100% humidity. Proprietary glass reinforcements give them exceptional

strength and stiffness.

Resin, Fiberglass and Stuffing Selection

Resin	Application Scope
Type O (Orthophthalic type)	Generally used for ordinary corrosive environment and also for sea corrosion, faintly acid corrosion as well as weathering ageing environment.
Type I ( Isophthalic type)	Generally used for the environment with stronger acidic corrosion or general one.
Type V ( Vinyl Ester type)	Generally used for serious corrosive environment with acid, alkali, solvent etc.
Type P ( Phenolic type)	Used for high fire resistance and low areas.

Fiberglass
Fiber Composition	Size	Property	Application Scope
Alkali-free Roving	2400TEX or 4800TEX	It is of good permeability, high bond with resin matrix, which makes the products be of excellent mechanical properties and corrosion resistance.	Used for high strength requirement and corrosion-resistant.
Medium Alkali Roving	2400TEX	It is of good permeability, high bond with resin matrix and high acid-resistance.	Generally used for serious corrosive environment

Stuffing
Stuffing Selection	Property	Application Scope
aluminium hydroxide powder	Flame-retarded, enhanced, oxygen index is above 28.	Flame-retarded, restraining smoke environment.
calcium carbonate powder	Enhanced, moderately lower cost.	No requirement for flame retardance.
No stuffing, pure resin	Good transparency	No requirement for flame retardance, high abrasion resistance.
