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 top coat, achieving 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 the use of acids or alkalis, resulting in no wastewater discharge, making it an environmentally friendly closed system method. Additionally, the low-temperature baking treatment minimizes the impact on the material's physical properties, demonstrating our thorough consideration for the environment in our processing technology. We can accommodate surface treatment lots of any size, starting from small-scale prototypes. Furthermore, if requested, we can leverage our network with various manufacturers to handle parts procurement and design, followed by surface treatment processing and delivery. If you have any concerns regarding surface treatment, rust prevention, or parts procurement, we will utilize our experience and know-how to provide you with the best proposals. Please feel free to consult with us.
