For many years, the Traditional Method of connecting reinforcing bars has been with lap splicing. But as many structural Engineers and Architects have discovered, lap splicing has quite a few Disadvantages when compared to Mechanical splicing. Continuous research has proved that the traditional method of connecting reinforcement bars with lap joints continuity in reinforced concrete is not always appropriate. Advantages of simplicity and economy in lap splicing is limited to smaller diameter bars. NANYA mechanical couplers offer the solution for splicing when large diameter bars are involved. The rising prices of Steel, Cement and labor has made it necessary to use Nanya Mechanical couplers to reduce the impact of this price rise on the cost of construction.
