Molten aluminum plated pipes are offered in cooperation with partner companies. 

 Carbon steel pipes given a molten aluminum plating are used mainly for factories, fishing vessel seawater plumbing, and heat transfer devices. 

 Steel pipes are placed in molten aluminum kept at around 700 degrees for several minutes to fully permeate the entire surface and create an aluminum membrane (aluminum oxide membrane + aluminum membrane + iron alloy layer). By doing this, heat resistance, corrosion resistance, abrasion resistance, and sulfur resistance, along with high durability are all conferred to the pipe.
