Ultra-high corrosion-resistant surface treatment comparable to austenitic stainless steel.
This is a composite surface treatment that combines alloy plating, alloy coating, and a topcoat to achieve ultra-high corrosion resistance despite being a thin film. By applying this treatment to iron materials, it is possible to impart corrosion resistance equivalent to austenitic stainless steels such as SUS304. Additionally, it is resistant to damage from self-tapping screws and tools, and is effective against sulfurous gas and salt damage, demonstrating high corrosion resistance in various scenarios.

Company information
At Kuroiwa Co., Ltd., we perform rust prevention surface treatment processes for metals, including Lafre, Disgo, Raspato, and Delta Protect treatments. Our processing does not involve any steps using acids or alkalis, resulting in no wastewater generation, making it an environmentally friendly closed system method. Additionally, due to the low-temperature baking treatment, there is minimal impact on the material properties, demonstrating our thorough consideration for the environment in our processing technology. We can accommodate surface treatment lots of any size, starting from small prototype quantities. Samples of treated products can be shipped free of charge. Furthermore, if requested, we can leverage our network with various manufacturers to handle parts procurement, perform surface treatment, and provide the finished products, or procure individual parts as needed. If you have any concerns regarding surface treatment, rust prevention, or parts procurement, we will utilize our experience and know-how to provide optimal proposals. Please feel free to consult with us.
