FRP PULTRUDED GRATING
Pultruded grating is suitable for applications with a large span and a high load. Pultruded grating is highly fire-resistant and can be used in various heavy industrial environments and chemical, aggressive and corrosive conditions.
Sinogrates Moulds Specification Table
SINOGRATES supplies pultruded FRP grating in various panel sizes and thicknesses, with variations in tie rod distance and open spaces. Fibreglass reinforced plastic (FRP [GRP]) pultruded grating can be fitted with a quartz surface (anti-slip layer) and a solid cover plate.
Pultruded Fibreglass Reinforced Plastic grating
Pultruded FRP grating is made of fibreglass reinforced plastic (FRP [GRP]).
Pultruded FRP (GRP) grating consists of pultruded load bars that are interconnected by means of tie bars. This grating can be supplied in a polyester, vinylester or phenolic resin. Phenolic resin has excellent properties with respect to. Due to the specific construction and the use of a high glass percentage (approximately 65-70%), pultruded Fibreglass Reinforced Plastic (FRP) pultruded grating is high in strength. Pultruded Fibreglass Reinforced Plastic grating is therefore widely applied in applications that require high strength and at a large span (from 1 to 2 metres).
This process creates continuous lengths of FRP with a consistent cross-section.
About Pultruded FRP Grating
Pultruded FRP Gratings are assembled from pultruded shapes. These shapes (I-Bars, T-Bars, etc.) are manufactured by pulling fiberglass rovings and mats through guides, then into a resin bath, then wrapped with a surfacing veil, then finally pulled through a heated die to form the desired bar shape. Once the bars are pulled, they are drilled for crossrods, then assembled by installing the crossrods spaced on 3" or 6" centers (depending on the grating type). These crossrods, that lock the bars into place, are then bonded with epoxy to ensure the bars will not move.

FAQ
What types of engineering load data is available for grating products?
<Uniform, concentrated point load - molded grating only, and concentrated line load tables are available for all our grating products.
What information is required to make a good resin system recommendation?
<In order for technical services to properly formulate a specific resin, they must have information about the application including chemical type, chemical concentration, temperature, and exposure level of the chemical to the product.
What type of grit is used on standard grit top grating products?
<Sinogrates standard grit is a quartz grit which is integrally applied, cured and sealed onto the surface of the grating.
When placing a grating order, what accessories should also be considered?
When placing an order, also consider these accessories: hold-down clips to secure grating, grating legs to elevate grating, EZ angles for corrosion resistant ledges, epoxy spray to seal cuts and penetrations, or saw blades to cut material.
Why should I seal areas on FRP products that have been cut, scraped, scuffed or scratched?
Any area that has been cut, scraped, scuffed or scratched should be sealed to prevent corrosive chemicals from reaching exposed glass fibers which maintains corrosion resistance, thus extending the life of the product.
What ergonomic benefits do Fibergrate FRP products have?
Unlike stiff metals, FRP provides deflection and resiliency to cushion steps and also reduce back and leg fatigue.
Nantong Sinogrates is always up to date on the relevant regulations relating to the specific applications. The company is therefore able to provide the customer with the most appropriate technical solution and guarantee product compliance with all applicable fundamental regulations.
