ZINC COATING FOR HYDRAULIC CYLINDERS
From agricultural products to oil drilling industry, you can see hydraulic cylinders doing the heavy work in almost all the sectors. The oil-based actuators are heavy, big and they more than lift, push, pull and crunch their weight. They are also exposed and most times the product the part of the machine that needs the most care. That is where zinc coating of hydraulic cylinders come in handy.
Also known as the Galvanization process, a protective layer of zinc coating is applied on iron or steel to protect against rust and outside elements. . And since the moment we started making hydraulic cylinders, we have offered zinc coating of hydraulic cylinders along with other paints and powder coating options.
While we do offer a variety of options when it comes to the protection of the outside barrel of hydraulic cylinders, zinc coating is an option we tout as well as refer to all our clients because there is just no comparison with anything out there in the market when it comes to protection.
WHY ZINC COATING OF HYDRAULIC CYLINDERS?
The obvious answer for zinc coating of hydraulic cylinder is protection against rust. Hydraulic cylinders are going to be out in the work, in the environment, sun, air, water all beating down on the metallic surface so the first and most obvious attack is always rust. Rusting of metals weaken the whole integrity of the cylinder and instead of applying another coat, the whole barrel of the cylinder needs to be replaced when rusts take hold.
But due to the sacrificial nature of zinc, they are electronegative compared to iron, when iron comes in contact with zinc, it oxidizes, protecting the underlying steel. The electronegativity of zinc works against the formation of rust. Even when a part of the zinc coated hydraulic cylinder barrel is exposed, zinc coating still protects the underlying steel as long as it is close enough to couple and oxidize.
