Free shipping worldwide UBC1997 standard building materials prices Mechanical coupler     Product Description Mechanical coupler  is widely used all over world nowadays. It provides a better way than traditional ways like lap joint, welding joint and cold pressing. Our parallel thread rebar couplers are used in many projects both home and abroad with good reputation.      Coupler material and its property:  

Raw material of couplers	Tensile strength ob(Mpa)	Yield strength os(Mpa)	Percentage of elongation after fracture
40Cr	over 980(100)	over 785(80)	over 9
45C	over 600(61)	over 355(36)	over 16

      Coupler Type 1. Standard coupler 2. Position coupler(left-right handed thread) 3. Transition coupler(different diameter)     Advantages of  Mechanical coupler  • No staggering of spliced bars required.
• Practical alternative to lap splicing.
• Solves bar congestion problems.
• Shortens construction cycle time.
• Reduces steel wastage.     Technical Parameters of  Mechanical coupler
