Light weight: FRP rods density is 1.9g/cm3, about 1/3 of the parking rod steel (steel sucker rod density is 7.85 g/cm3), can greatly reduce the gate suspended load, so you can use small power motors, smaller gearbox, smaller balance blocks, lighter structure. In order to save energy, improve the comprehensive efficiency of the.
Good flexibility: the elastic modulus of FRP rods for (4.0-6.0) * 104MPa, only about 1/4 of the steel gate rod (elastic modulus of steel gate rod is 2.1 * 105MPa), it can prolong the service life of the gate, but also can increase the effective stroke of the gate, increase the effective opening and closing times.
Strong corrosion resistance: glass steel has corrosion resistance and good fatigue properties; glass steel joints can be made with the corrosion resistance of steel rod is mainly composed of alkali free glass fiber roving, and thermosetting resin after fully soaking by preheating and curing, is a non conductor of electricity, containing carbon dioxide, hydrogen sulfide environment experiment in saline and no corrosion phenomenon. This can reduce the condition of stopping the operation because of the fracture of the brake rod caused by the corrosion, and reduce the operating cost and increase the production efficiency.
High strength: tensile strength of FRP rods for 810MPa, reached the tensile strength of D steel, the biggest short-term stress of 300MPa, the maximum load of up to 15t.
