1.Super Upsetting Couplers Introduction

Upsetting technology is using a parallel-thread mechanical splicing system designed for the connection of 16mm to 40mm reinforcing bars in the construction working site. This system is using cold upsetting and Metric thread Cutting process which can make sure about the rebar connection tensile strength make the bar break.

This Best quality parallel upsetting couplers is in compliance with China standard UK standard, USA standard and also other international standards. Its very popular in the rebar connection filed

2.This Black surface upsetting couplers Features and advantages

a.This technology will not reduce the rebar diameters and  it will enlarge it

b.Fast Installation without torque wrench operation

c.Assemble easy by visual inspection

d.It is Standard ISO parallel Metric Thread used for most of the countries.

e.Standard coupler can be used both for standard splice and position splice.

f.This mechanical connections are quicker, safer and mover convenient ways than old type lap splicing or welding splicing.

3.Rebar Processing Working Steps

a.Cutting the rebar end to make it flat



b.Enlarge the rebar diameter by cold upsetting



c.Making the parallel thread by cutting



d.Connect the rebars and make sure the barbreak
