Characteristics of Pre-stressed CFRP plate reinforcement
Reinforcement technology of prestressed carbon fiber reinforced polymer laminate is 4-6 times higher strength than that of non prestressed carbon fiber reinforcement technology.t can not only improve the bearing capacity of concrete beams, but also significantly improve the service performance of reinforced beams.

Steel plate bonding reinforcement application
Steel plate bonding reinforcement method has been widely used in strengthening engineering, its basic principle is using high performance epoxy adhesive bonded the steel plate to the concrete, so as to form a unified whole, to achieve the purpose of strengthening and enhancing the strength and stiffness of the original structure.
