  2. About business

Our factories are fully equipped with surface treatment & paining facilities. We have built integrated production system which is from pipe production, surface treatment, painting, and efficiency of transportation. We response not only turnkey contract from pipe production, surface treatment and painting, but also each needs and visiting service. We take care of matters as they come. By integrated production system, We do short deadline, simplify procedures, low logistic cost.

Pipe production

We produce mainly 15A-400A pipes which are handled at shipyard. In these year, we also response needs for plant&engine and expand our business area to diversified small-quantity production.

Surface treatment

Acid cleaning

Create added value from rust-preventative treatment, passivate film and improvement durability&mechinability by removal pollutant, impurities. Acid cleaning is our main technology and know-how intensive area about surface treatment. In recent year, cleaning line longest which is biggest line on west japan 12m has been completed.

Steel products

Build a rust-preventative film for each purpose by removal foreign substance

Main process

Various treatment such as 'Degreasing' removing oil, varnish, paint, 'Acid cleaning' removing rust, mill scale, gilding. We treat a diversity of rest-preventative treatments such as 'Phosphate film treatment', 'Alkali rust-preventation treatment' which is excellent for rust-preventation, 'Zinc phosphate film treatment' which is excellent for pain-adhesion, 'Manganese phosphate film treatment' which is good for mechanical sliding.

Visiting service

We response visiting service with high-pressure washer, chemistry and gathering tank of waste by customer's request. Not only domestic experience, but we have visiting service experience aboard such as Mexico and Singapore. Regarding customer's needs, we suggest produce and sort of quality test. One of our experience at chemical plant, we analyzed the sample of impurities at our lab and suggested optimum chemistry and produce based on the result and development. At the result, we received a favorable evaluation

Response to needs of our customer is our moto of R&D. Our R&D suggest latest technology based on their own comprehensive result of quality test, experiment, analysis, produce about the subject what our production spot face the difficult task of with specialized equipment in our lab on 3th floor of our head office. Regarding development order, we decide optimum new development, improvement, produce based on beaker experiment. Then we make final proposal after we repeat pilot production in our factory and evaluation. In these later years, we cooperate with national research institute or collaborate with R&D team of other makers.
