FRP bolts, FRP Studs,Fiberglass Bolts, Fiberglass screws
Product Description
FRP Bolts and Nuts is kind of Composite fasteners ，It is a good choice for applications that demand non-corrosive and non-conductive material properties. FRP nuts and bolts can be used in place of typical steel fasteners. It is made of E-glass fiber and epoxy resin, carbon fiber and vinyl ester resin also be available. Use unique fiberglass -oriented method, it has excellent high strength, high durable and high corrosion-resist.

FRP bolts VS Steel bolts
1.1 Light and high strength
the density of FRP materials is much lower than that of traditional metals, but through reasonable fiber laying and resin selection, high strength and toughness can be obtained, especially suitable for those applications that have strict requirements on weight, such as aerospace, racing, ships and so on.
1.2 Corrosion resistance
FRP material has good corrosion resistance to a variety of chemical substances, suitable for coastal, chemical plants and other corrosive environment, can effectively extend the service life and reduce maintenance costs.
1.3 Non-conductive
As an insulating material, FRP bolts have their unique advantages in electrical insulation and lightning protection, and are suitable for structural connections requiring insulation properties such as power facilities and communication towers.
1.4 Low thermal conductivity: The thermal conductivity of FRP is low and can be used in occasions where heat insulation or thermal bridge effect is required.
1.5 Strong designability
FRP can be molded to produce bolts of various complex shapes and sizes with smooth surface.
1.6 Shear strength and hardness
Fiberglass bolts also have some limitations, such as their shear strength and hardness are usually not as good as metal bolts, and their performance will decline at extremely high temperatures. Therefore, it is necessary to weigh its advantages and disadvantages according to the specific application requirements when selecting. In addition, due to the particularity of FRP bolts, their production process is relatively complex, and the cost may also be higher than that of ordinary metal bolts.
Application Field
Fiberglass composite fasteners are ideal for applications that demand non-corrosive and non-conductive material properties. FRP bolt and nut combinations are commonly found in chemical equipment, Marine engineering, electrical insulation connection, outdoor facilities and other fields with high requirements for lightweight, corrosion resistance and insulation.
Installation Notice
Since the hardness and strength characteristics of FRP materials are different from steel materials, special tools or techniques may be required during installation to avoid damaging threads or fasteners. At the same time, proper preload control is also very important to ensure the stability of the connection.
Cost and Life
Although the initial investment may be high, due to its excellent corrosion resistance and long life, it can reduce the cost of maintenance and replacement in the long term, especially in harsh environments.
