The company operates as a B2B industrial supplier with a monthly production capacity of 4,000 tons and more than 100 size-specialized tube manufacturing machines, producing round tubes, square tubes, specialty shapes (oval, semicircular, channel, flat-square), clad tubes (MS/TC pipes), stainless steel bars, flexible pipes, handrail components, and carbon steel products. Its manufacturing technology spans argon arc, high-frequency, and laser welding processes, enabling production across grades including SUS304, SUS316, titanium, and special alloys, with applications in automotive exhausts, construction/architecture (including visible installations at Tokyo Dome), industrial piping for petroleum/chemical/power/water-treatment/fuel-cell facilities, and precision medical and heat-exchange equipment.

The company serves customers through direct B2B sales supported by affiliated companies, with manufacturing subsidiaries Kanto Mory Industries (Saitama and Joso factories) providing domestic regional coverage and a Mori-navi web catalog platform (launched May 2021) enabling remote inventory checks, quoting, and ordering. International footprint includes a 95.4%-owned Indonesian subsidiary (PT. MORY INDUSTRIES INDONESIA, established October 2012) and a 40% stake in Thailand's Auto Metal Co., Ltd. (acquired October 2010), both primarily serving four-wheel and two-wheel automotive tube demand.
