   bar with coupler without any change(physical,

   chemical) for civil engineering and construction.

   It has a good property on earthquake-proof,

   durability better than existing installation method

   or product.

█ Applications

① Can’t be constructed with already installation   

    method using large reinforcing bar for a big

    constructions.

② Be longer than installation length by structure

    calculation.

③ Splice bar to bar in civil engineering and

    construction site.

① Mechanical property of coupler better than

     installed bar. 

② Fast and simple installation.

③ Can be installed in other size bar.

④ Can be installed vertical/horizontal line, band

     reinforcing bar. 

⑤ Must be contributed to improve durability on

     a strong wind, gale.

⑥ Can be designed on earthquake-proof.
