FRP REBAR

FRP REBAR


JyyToo manufactures high quality FRP Rebar in accordance with CSA 807and ACI 440 codes using pultrusion process, as stronger and lighter alternative to conventional steel rebar. Its significant advantages include ¼ the weight of steel, superior in tensile strength, corrosion-free, non-magnetic, non-conductive, and so forth. It is specified for use in roadways, bridges, dams, concrete slabs, barrier walls, marine applications, tunneling and temporary reinforcement, and power generation facilities.

Composite glass fiber reinforcement is one of the most popular and modern building material spread all over the world.

This popularity is explained by the fact that composite reinforcement has some advantages in comparison with steel reinforcement. Everybody knows that steel reinforcement is very heavy and it takes a lot of energy and time to install it.Moreover, it exposed to corrosion which could cause earlier destruction of concrete construction.

Composite reinforcement is light weight and noncorrosive that means that using of it is profitable.

Properties and application of composite reinforcement

Composite reinforcement is the product made of glass fibers bind with thermosetting resins. Its main specialty is lightness mass index calculated using the unit of volume is only 2 g/mm3. Working with this material is much easier and more profitable than working with metal reinforcement. There are less spendings while transporting and armoring.

Composite reinforcement is used while building civil, public and industrial constructions as reinforcing frame of foundations, floors and beams.

In road repairing works composite reinforcement is used for arranging of fillings, traffic-bearing surface in bridge construction and in highway barriers. It is resistant to all types of deicing agents and might be used in all regions.

The use of high-durability resin as the main matrix material has top-notch corrosion resistance and is one of the best solutions to solve the corrosion of steel bars. It can be used in chemical engineering, salt spray environment, bridge deck paving, marine and other projects. The corrosion resistance of the reinforcement meets the highest level D1 durability requirements defined in the Canadian ISIS certification specification.

Our company specializes in the production of glass fiber reinforcement for subways, which complies with the relevant regulations of CJJ-T192-2012 "Technical Regulations for Shield Machinable Concrete Reinforcement" and JGT 406-2013 "Glass Fiber Reinforcement for Civil Engineering". Wall construction, replacing steel bars in soft-eye engineering, facilitates construction, reduces costs, and makes the owner highly trust and insist on the product.
