Protecting steel from rusting is crucial for the longevity and effectiveness of an anchor. Zinc-coated steel through a hot galvanizing process is the most effective method to achieve this. The type of steel used to make anchors is also critical as it determines its strength, metallurgical quality, and behavior. At Viking Anchors, we use Hardox450 HT steel with a minimum yield strength of 1,250 Mpa, giving our anchors incredible lightness and holding power.
When selecting the right steel to build anchors, a compromise has to be made between the grade of steel, weight, and price. Higher tensile metals are more expensive and harder to cut, bend, and weld. The shank is a common failure point for any anchor, which can bend when a high lateral load is applied. To minimize such events, we use only high-grade high-tensile steel to build our anchors.
We preheat the shanks before welding, which is the recommended technique for this type of material. The result is an anchor stronger than one made from mild steel that would weigh considerably more. Our shanks are buried deeper, which increases the burial of the anchor and leaves less or no shank exposed. If there is lateral tension applied, our shanks act as a vertical fluke supported by the seabed, minimizing the risk of bending.
All of our steel anchors are treated with a "hot-dipped galvanizing" process that exceeds industry standards, resulting in a minimum coating layer of 100-micron. In every new batch of anchors, we use a coating thickness meter to check the galvanizing thickness, ensuring the durability of our anchors.
Investing in a Viking Anchor means investing in a technically sound and durable anchor that offers worthwhile benefits. Our high-grade steel and anti-rust treatment ensure that our anchors can withstand harsh marine environments and provide reliable holding power.
