Composite (GFRP) Gratings : What is GFRP (Glass Fiber Reinforced Plastic)?
GFRP is a composite material made of a polymer matrix reinforced with fiber, aiming to form better physical and chemical properties. GFRP is a production material such as metal, wood, glass, concrete. GFRP materials has important advantages as against other production materials, new features can be acquired according to requirements.
What is GFRP Grating?
Molded GFRP gratings are produced in special molds with wet lamination process, consist of glass fiber, resin, additives and pigment. After these raw materials harden, GFRP gratings are pressed out of the mold. Molded GFRP gratings are light, anti-corrosive, have high chemical and physical resistances and electrically non-conductive.
Components: Resin, glass fiber, additives and pigment are the basic components of the GFRP materials. It can be produced any material which are proper for the requirements by changing these components.
Resin: Chemical resistance, flexibility and UV resistance of the GFRP gratings are determined by the resin. Resins are chose according to the environment; orthophthalic resin for general usage, isophthalic resin for chemical environment and vinyl ester resin for extremely heavy chemical environment.
Glass Fiber: Multi-layered continuous glass fibers are used in production. Molded GFRP gratings have high mechanical resistance due to glass fiber.
Additives: Additives such as UV stabilizers, flame retardants and low smoke density retardants increase mechanical and chemical resistance and add new superior features.
Pigment: Pigments make it possible to give the GFRP gratings any color. This makes it happen to use GFRP gratings in architectural projects.
Fibre-reinforced plastic (FRP) (also called fibre-reinforced polymer, or fiber-reinforced plastic) is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass, carbon, aramid, or basalt. Rarely, other fibres such as paper, wood, or asbestos have been used. The polymer is usually an epoxy, vinylester, or polyester thermosetting plastic, though phenol formaldehyde resins are still in use.
FRPs are commonly used in the aerospace, automotive, marine, and construction industries. They are commonly found in ballistic armor as well.
A polymer is generally manufactured by step-growth polymerization or addition polymerization. When combined with various agents to enhance or in any way alter the material properties of polymers the result is referred to as a plastic. Composite plastics refer to those types of plastics that result from bonding two or more homogeneous materials with different material properties to derive a final product with certain desired material and mechanical properties. Fibre-reinforced plastics are a category of composite plastics that specifically use fibre materials to mechanically enhance the strength and elasticity of plastics.
The original plastic material without fibre reinforcement is known as the matrix or binding agent. The matrix is a tough but relatively weak plastic that is reinforced by stronger stiffer reinforcing filaments or fibres. The extent that strength and elasticity are enhanced in a fibre-reinforced plastic depends on the mechanical properties of both the fibre and matrix, their volume relative to one another, and the fibre length and orientation within the matrix.[1] Reinforcement of the matrix occurs by definition when the FRP material exhibits increased strength or elasticity relative to the strength and elasticity of the matrix alone.
FRP can be applied to strengthen the beams, columns, and slabs of buildings and bridges. It is possible to increase the strength of structural members even after they have been severely damaged due to loading conditions. In the case of damaged reinforced concrete members, this would first require the repair of the member by removing loose debris and filling in cavities and cracks with mortar or epoxy resin. Once the member is repaired, strengthening can be achieved through wet, hand lay-up of impregnating the fibre sheets with epoxy resin then applying them to the cleaned and prepared surfaces of the member.
Two techniques are typically adopted for the strengthening of beams, relating to the strength enhancement desired: flexural strengthening or shear strengthening. In many cases it may be necessary to provide both strength enhancements. For the flexural strengthening of a beam, FRP sheets or plates are applied to the tension face of the member (the bottom face for a simply supported member with applied top loading or gravity loading). Principal tensile fibres are oriented in the beam longitudinal axis, similar to its internal flexural steel reinforcement. This increases the beam strength and its stiffness (load required to cause unit deflection), however decreases the deflection capacity and ductility.
For the shear strengthening of a beam, the FRP is applied on the web (sides) of a member with fibres oriented transverse to the beam's longitudinal axis. Resisting of shear forces is achieved in a similar manner as internal steel stirrups, by bridging shear cracks that form under applied loading. FRP can be applied in several configurations, depending on the exposed faces of the member and the degree of strengthening desired, this includes: side bonding, U-wraps (U-jackets), and closed wraps (complete wraps). Side bonding involves applying FRP to the sides of the beam only. It provides the least amount of shear strengthening due to failures caused by de-bonding from the concrete surface at the FRP free edges. For U-wraps, the FRP is applied continuously in a 'U' shape around the sides and bottom (tension) face of the beam. If all faces of a beam are accessible, the use of closed wraps is desirable as they provide the most strength enhancement. Closed wrapping involves applying FRP around the entire perimeter of the member, such that there are no free ends and the typical failure mode is rupture of the fibres. For all wrap configurations, the FRP can be applied along the length of the member as a continuous sheet or as discrete strips, having a predefined minimum width and spacing.
Slabs may be strengthened by applying FRP strips at their bottom (tension) face. This will result in better flexural performance, since the tensile resistance of the slabs is supplemented by the tensile strength of FRP. In the case of beams and slabs, the effectiveness of FRP strengthening depends on the performance of the resin chosen for bonding. This is particularly an issue for shear strengthening using side bonding or U-wraps. Columns are typically wrapped with FRP around their perimeter, as with closed or complete wrapping. This not only results in higher shear resistance, but more crucial for column design, it results in increased compressive strength under axial loading. The FRP wrap works by restraining the lateral expansion of the column, which can enhance confinement in a similar manner as spiral reinforcement does for the column core.

What is Polypropylene (PP), and What is it Used For?
Polypropylene (PP) grating is a type of plastic grating that is widely used in various industrial and commercial applications. It is made from high-density polypropylene resin and is known for its high strength, durability, and resistance to chemicals and UV radiation.
The specifications of polypropylene grating may vary depending on the application and the manufacturer, but some general specifications include:
- Material: High-density polypropylene resin
- Mesh size: Typically ranges from 12mm to 50mm
- Thickness: Typically ranges from 15mm to 60mm
- Panel size: Can be customized according to the application
- Color: Typically gray or black, but other colors may be available upon request
- Load capacity: Varies depending on the size and thickness of the grating
Polypropylene grating is commonly used in the following applications:
Industrial flooring: Polypropylene grating is an ideal flooring material for industrial environments because of its high strength and chemical resistance. It is commonly used in chemical plants, oil and gas refineries, and other heavy-duty industrial settings.
Walkways and bridges: Polypropylene grating can be used to create walkways and bridges in wet or corrosive environments. It is also commonly used in parks and recreation areas as a non-slip surface.
Drainage systems: Polypropylene grating can be used in drainage systems to prevent clogging and facilitate the flow of water. It is commonly used in stormwater management systems and wastewater treatment plants.
Aquaculture: Polypropylene grating is used in aquaculture applications to create walkways, docks, and platforms. Its resistance to chemicals and UV radiation makes it an ideal material for use in marine environments.
Overall, polypropylene grating is a versatile and durable material that can be used in a wide range of applications where strength, durability, and chemical resistance are required.
Some of the most significant properties of polypropylene are:
Chemical Resistance: Diluted bases and acids dont react readily with polypropylene, which makes it a good choice for containers of such liquids, such as cleaning agents, first-aid products, and more.
Elasticity and Toughness: Polypropylene will act with elasticity over a certain range of deflection (like all materials), but it will also experience plastic deformation early on in the deformation process, so it is generally considered a "tough" material. Toughness is an engineering term which is defined as a material's ability to deform (plastically, not elastically) without breaking..
Fatigue Resistance: Polypropylene retains its shape after a lot of torsion, bending, and/or flexing. This property is especially valuable for making living hinges.
Insulation: polypropylene has a very high resistance to electricity and is very useful for electronic components.
Transmissivity: Although Polypropylene can be made transparent, it is normally produced to be naturally opaque in color. Polypropylene can be used for applications where some transfer of light is important or where it is of aesthetic value. If high transmissivity is desired then plastics like Acrylic or Polycarbonate are better choices.
Polypropylene is classified as a thermoplastic (as opposed to thermoset) material which has to do with the way the plastic responds to heat. Thermoplastic materials become liquid at their melting point (roughly 130 degrees Celsius in the case of polypropylene). A major useful attribute about thermoplastics is that they can be heated to their melting point, cooled, and reheated again without significant degradation. Instead of burning, thermoplastics like polypropylene liquefy, which allows them to be easily injection molded and then subsequently recycled. By contrast, thermoset plastics can only be heated once (typically during the injection molding process). The first heating causes thermoset materials to set (similar to a 2-part epoxy) resulting in a chemical change that cannot be reversed. If you tried to heat a thermoset plastic to a high temperature a second time it would simply burn. This characteristic makes thermoset materials poor candidates for recycling.
