Fiberglass Grating

Product description

Fiberglass grating and glass fiber reinforced plastic plate, is a kind of glass fiber reinforced material, unsaturated polyester resin as matrix, through special processing and become a kind of plate material, with lots of blank space FRP gratings can be used as a structural material, used for the floor of the corrosion environment, trench cover, platform, ship deck, stair, catwalks, etc.With corrosion resistance and flame retardant, non – magnetic insulation, bright colors, a variety of styles and forms of alternative features

Product feature

1.Corrosion resistance
Different resin properties give FRP different corrosion resistance, so that in different acid base, salt, organic solvent gas, liquid medium corrosive environment for a long time to use.
2.Flame retardant
High quality resin and flame retardant additives give the products excellent flame retardant performance, the general flame retardant products oxygen index is greater than 26, flame diffusion coefficient is less than 25, smoke density is less than 500.
3.Light weight and high strength
The perfect combination of alkali free glass fiber yarn and resin gives the product unique characteristics of light weight and high strength. The specific gravity of the product is 1/4 of that of steel, which is suitable for all kinds of bearing structures in corrosive environment.
4.Aging resistance
The product is made of high quality matrix resin and anti-aging additive, so that the product has long-lasting anti-aging performance, can maintain long-term luster and continuous high strength, and the service life is 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 the customer’s requirements, and the external dimensions can be cut and splice into the customer’s required size.
6.Safety and non-slip
High modulus of elasticity and different surface effect make the grille has anti-skid performance, slightly elastic to reduce the fatigue of the staff, double plane, crescent, sand surface, diamond front, different surface provides different application of anti-skid performance.
7.Electrical properties
Glass fiber and high performance resin give the product superior electrical performance, the product penetrable impact strength can reach 10kV /mm, metal tools to fight no electric spark;The product is non-magnetic and can be used safely in anti-electromagnetic and anti-explosion environment.
8.Economy
Because fiberglass does not need to maintain cost, and life is long, so comprehensive benefit is better

Manufacturing technique

There are three main types of GRP production process: reciprocating fiber winding process, continuous fiber winding process and centrifugal pouring process.
1.Reciprocating filament winding process (n) : in this process, the leaching glue tank with rotating mandrel for reciprocating motion, the long fiber glass with a certain Angle relative to the mandrel axial auxiliary, auxiliary Angle (that is, the winding Angle) baptism glue tank movement speed and the ratio of the core mold speed control, soak glue tank translational motion by computerized machine electric control.The number of winding layers increases gradually until the designed wall thickness is reached.After winding, the resin in the product is basically cured.After curing, the mold is removed from the glass tube.
2.Continuous filament winding process (continuous process) : the pipe is made in the continuous advance of the mandrel through a feed station for resin prepreg, non-twist roving, short-cut fiberglass and resin sand mixture.
3.Centrifugal pouring process (n) : in this process, using glass fiber reinforced materials and sand, feeding on the bearing steel in the mould, injection plus unsaturated resin catalyst in die end, make its dipping reinforced material, under the effect of centrifugal force, the resin exchange fiber and filler in the air, so as to create a nonporous compact composite material, the effect of tube wall due to centrifugal force to form a smooth, bright and clean surface layer of rich resin, steel tubes under high temperature curing.Tubes manufactured in this way are also known as glass reinforced plastic sand tubes.

14.Others: corrosion resistant shelves, decoration, square fountain, scaffolding, civil construction facilities, breeding fences and double floors, etc.

Product Notes

1.Due to the low density and light material, it is easy to install fiberglass grilles floating pipes in areas with high underground water level. Anti-floating measures such as town piers or rainwater runoff drainage must be taken into consideration.
2.In the construction such as opening a tee on the installed FIBERglass grille and repairing pipe cracks, it is required to be similar to the completely dry conditions in the workshop, and the resin and fiber cloth used in the construction should be cured for 7-8 hours. However, on-site construction and repair are generally difficult to meet this requirement.
3.Existing underground pipeline detection equipment is mainly used to detect metal pipelines, while non-metallic pipeline detection equipment is expensive, so it is impossible to detect FRP grilles after they are buried in the ground. Other subsequent construction units are prone to dig and damage pipelines during construction.
4.Fiberglass grilles have poor uv protection.Open-mounted FRP grillers are retarded by the fabrication of a 0.5mm thick resin rich layer and uv absorbent (in-plant processing) on the surface.Over time, the resin rich layer and uv absorbent will be destroyed, which will affect its service life
