Type-A

“Type A” is one touch coupler with
manual locking type one touch coupler.

Type-B (Hybrid)

“Type B” is Hybrid type coupler this type to be supplied directly by the rebar manufacturer or rebar processing companies which threaded on one side and one touch on the other side

Type-C (Slip zero)

“Type C” is for “High-End customer” and can be used to lock both coupler by using Hydraulic devices and implement SLIP ZERO which does not slip after rebar being connected.

Type-D (Standard/Pre-cast)

“Type D” is not a lock type and is the most commonly used type. Type D can also be used as "Pre-cast(PC) concrete work" and type D does notrequireadditionallocking.

1. Welding Type(fixing) coupler

2. Procedure for Installation

2.1 General connect

Insert the coupler into the rebar, And insert the rebar to be joined to the other side of the coupler. No separate machining is required for the rebar.

※ For perfect rebar connection, the sharp edge of the rebar end shall be properly removed by grinding.
2.2 Connecting on iron structure
① Welding coupler : Welding coupler with a joint for fixing (welding) to an iron structure
② Welding coupler(fixing coupler)
To secure the fixing length, hook construction is not performed, and mechanical joints, that is, one-touch couplers, are used at the end of the reinforcement
