Since its establishment in 1953, OSAKA KAKO CO.,LTD. has been consistently working on research and development of lead, and our unique ideas and advanced processing technology enabled us to create various lead products. Taking advantage of its main characteristics of lead, we have supplied products for many applications including: radiation shielding( X-ray protection for general industry, construction or medical purposes), sound insulation, water proofing, corrosion protection, nuclear energy shielding, or vibration absorbers. The core products we manufacture are lead sheets, lead wool, lead bricks, lead composite boards, lead tapes, lead containers etc. In recent years, we are specially devoted to develop lead items for radiation shielding. As a result of it, we gained several patents in our country Japan, with our newly developed items.
