FRP Pultruded Grating Fire Retardant/Chemical Resistant

Sinogrates@pultruded grating has the advantages of corrosion resistance, long life and low maintenance costs, which is better than traditional metal grating. This advanced technique is made of embedded tie rod, which is light and easy to manufacture. This advanced FRP pultruded grating design is used for high-strength and corrosive industrial environments. FRP pultruded gratings are composed of high percentage of fiberglass roving in layer pressure plates, which have durability, high unidirectional strength and stiffness. Due to its excellent stiffness, it can be used with confidence to be used with large span support. Most of the applications for replacing steel gratings. Sinogrates FRP pultruded gratings have the characteristics of low installation costs, low maintenance costs, and long service life. The life cycle cost is significantly lower than that of metal materials.

Pultrusion process is a manufacturing process for producing continuous lengths of reinforced polymer structural profiles with constant cross-sections. Raw materials are a liquid resin mixture ( resins,fillers and specialized additives) and flexible textile reinforcing fiberglass rovings . The process involves pulling these raw materials (rather than pushing, as is the case in extrusion) through a heated steel forming die using a continuous pulling device.

The reinforced materials are in continuous forms such as rolls of fiberglass mats and doffs of fiberglass rovings. As the reinforcements are saturated with the resins mixture ("wet-out") in the resin bath and pulled through the die, the gelation, or hardening, of the resin is initiated by the heat from the die and a rigid, cured profile is formed that corresponds to the shape of the die.
The resins include Orthophthalic resin, ISOphthalic resin, Vinyl ester resin, epoxy resin,and phenolic resin.FRP pultruded gratings is assembled and composed of crossing bars and I and H profiles,which are a high-strength and high- corrosion resistance. It has a maximum of 70% and the minimum of 65% of the fiberglass roving and synthetic surfacing veils. thereby improving corrosion resistance and ultraviolet resistance.

Non-slip surfaces treatment: The grating will be bonded with a layer of quartz sands on top surfaces . You could request non-slip surfaces according to your projects.

Molded Fiberglass GRP Top choics:

The top crescent surfaces : there is no quartz sands on the concave or semi-lunar surfaces,which provide excellent anti-slip effects in wet, muddy or oily environments, and is one type of the commonly basic anti-slip grating.

The quartz sands surfaces: laying quartz sands on the top surfaces of FRP grating, the solidified quartz sands and covered on the top surfaces, which can provide an excellent anti -slip effects.

Products capacities test laboratory:

The meticulous experimental equipment for FRP pultruded profiles and FRP molded gratings ,such as flexural tests,tensile tests,compression tests, and destructive tests. According to customers’ requirements,we will conduct performances & capacities tests on FRP products ,keeping the records to guarantee the quality stability for long-term.meanwhile, We are always researching & developing innovative products with testing the reliability of FRP product performance. We can ensure that the quality can satisfy customers’ requirements stably to avoid unnecessary after-sales problems.

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): A nice choice for applications where chemical splashes and spills are a common occurrence.
Food Grade Isophthalic resin (Type F): Ideally suitable for food and beverage industry factories which are exposed to strict clean environments.
General Purpose Orthothphalic resin (Type O): economic alternatives to vinyl ester and isophthalic resins products.

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.
