2 Common in the constructions of inclined columns, long columns, long beams cantilevered structures where tensile loadings are greater than normal congestion of reinforcement bars in heavily reinforced structures due to laps. Reduce concrete / steel ratio and improve concrete quality by having bigger space between formation of voids or honey-comb in concrete expensive SYSTEM formwork from being damaged by starter stains, corrosion and breakage of starter bars left for future extension of buildings and other structures. Promote construction of bridge in stages to ensure constant flow of traffic during bend and re-bend of bigger reinforcement bars in construction of diaphragm spacing between bars are insufficient to allow for laps in construction of size of concrete sections and ensure maximum usage of expensive floor space in office a full tension splice is required in connecting precast members to cast-in-situ ASSURANCEU nder HalfenMoment Quality Assurance Program, we pride ourselves for the practice of the highest levels of control and precision product are designed, manufactured, inspected and tested to ensure that every single pieces is according to specifications.

3 Every step of the process is being monitored by our stringent internal QC coupler are stamped with traceability codes, which allows the couplers to be traced back to the original lot of steel and the mill which produced it.
