Dacromet utilizes a zinc-flake coating that provides significantly higher salt spray resistance (up to 1000+ hours) and avoids hydrogen embrittlement, which is critical for high-strength structural fasteners.
Yes, they are highly recommended for marine applications, including deck hardware and offshore structures, due to their extreme resistance to saltwater corrosion.
Our products are manufactured in strict accordance with DIN125, ISO 7089, DIN 9021, and ANSI B18.22.1 standards to ensure global compatibility.
Absolutely. The Dacromet process is a heavy-metal-free coating method, making it a sustainable alternative to traditional plating processes that use hexavalent chromium.
Our Dacromet coated washers can maintain their protective properties at temperatures up to 300°C (572°F), making them ideal for exhaust systems and industrial furnaces.
Yes, we provide comprehensive material certifications, hardness test reports, and salt spray testing data to ensure the quality and safety of your structural installations.
