Promote from domestic de facto standard to global standard

Inherit the know-how and skills from previous skilled worker

Criteria when using DB Head from manufacture to construction are highly effective

General rebar work (Rebar processing・Rebar assembly)

Since its founding, we have always pursued honesty・accuracy・quickness,
taking on the role of the leader in the industry in the development of advanced equipment and techniques of Chuubu region.

Using Pre-assembly method to solve construction time problems and lack of wokers

We want to become a VE (Value Engineering) leader.
According to VE proposals, we are actively working on the unit assembly method of construction using DB Head or unit rebar welding machine to shorten the time construction, reduce construction cost, ensure the quality and safety.

Based on advanced technology and knowledge, we propose possible solutions(e.g. new bar processing technology, improve quality, market development , enforcement methods…) for problems and issues facing the industry from a professional viewpoint

We do consistently rebar processing in the factory
We not only accept normal rebar processing but also special rebar processing
