basic information
【Rust Prevention Department】 Metals naturally rust in the atmosphere and in water, which not only detracts from the aesthetic appeal of the products but also adversely affects the performance of the metals in various ways. To prevent such issues from occurring, it is necessary to protect the surface of the metal by some means. In recent years, significant advancements in technology have led to the development of highly durable coatings. One essential process that is always performed as a surface treatment for this coating is "shot blasting." No matter how durable the coating is, it cannot demonstrate its full potential without complete surface preparation, making shot blasting indispensable. Our company’s Rust Prevention Department has been engaged in research and development of shot blasting for many years. Harada Ironworks Co., Ltd.
