The term FRP bar refers to Fiberglass Reinforced Polymer rebar or sometimes it’s called fiber-reinforced plastic. FRP Rebar is an alternative to steel reinforcement in concrete structures. Such rebars are made of continuous aramid fiber (AFRP), carbon fiber (CFRP), glass fiber (GFRP) or basalt fiber (BFRP) embedded in resin matrix.
No, FRP exists in the market since the 2nd world war. Its quality improved a lot since.
Steel reinforcement of concrete has been used for many years, however, its primary shortcoming is that it is easily corroded, and corrosion results in structural failure. Recently, the use of FRP bars as internal reinforcement for concrete structures in aggressive environments has arisen as an inventive solution to eliminate steel corrosion problems. FRP rebar has an advantage over steel, since it is closer to the modulus of concrete. Also, a concrete structure reinforced with FRP rebars does not react to the chloride-rich environment. In addition, GFRP bars have recently gained wide acceptance as a viable construction material for sustainable new constructions due to their costing less than other FRP types.
The basic raw materials for fiberglass products are a variety of natural minerals and manufactured chemicals. The major ingredients are silica sand, limestone, and soda ash. Other ingredients may include calcined alumina, borax, feldspar, nepheline syenite, magnesite, and kaolin clay, among others.
Fiberglass is non-combustible. It simply won’t burn. If a fire gets hot enough, it will just melt. However, fiberglass batts that are covered with Kraft paper or a foil facing are combustible.
FRP material is not flammable you may check about it on OSHA. No FRP is flammable. Due to this reason, almost all the industrial sectors are using the fibreglass reinforced polymer over the conventional steel.
FRP bars are non-conductive material in terms of both thermal and electrical conductivity. Hence, you can keep your structure eco-friendly by using our bars.
FRP/GRP products are an eco-friendly alternative to many traditional materials. Choosing FRP/GRP products is an environmentally responsible choice. FRP/GRP has low embodied energy. … As a good insulator against heat and cold, FRP/GRP helps conserve energy while reducing operating costs.
This bar can be cut with a manual rebar cutter; bolt cutters; grinder or Sawzall cut rebar. In the absence of these tool, however, rebar can be cut with a hack saw.
This rebar cannot be bent after the curing cycle. All bends need to be fabricated in our manufacturing plant in China.
At the end of the ACI 440.1R-15 guideline, there are many structural calculation samples for different structural elements. Also, our engineering team can assist you with the conversion of steel drawings to FRP.
The most usable diameters of GFRP straight rebars are ready for shipping to your site. For the bent rebars, it takes around 2-3 weeks for production based on the required quantity. Shipping time is usually 3-4 weeks.
Our plants in china can provide you with all alternative diameters for steel rebars from #2 (6mm) up to #10 (32mm) bent and straight GFRP bars.
All common shapes can be fabricated in our plants. As it is shown on our website, we can fabricate L-shape; U-shape; Z-shape, stirrups; spirals; hooks, as well as specific shapes based on our client request.
We assure our clients that our FRP pricing is competitive with steel.
