Buy a Zintec also known as Electric Zinc Coated Sheet (EZC), Zinc Plated Mild Steel in stock for next day delivery. Zintec is a cold rolled metal sheet thinly coated with a layer of zinc. Often used in pressed products across the construction industry. We stock zintec in a variety of thickness. In addition to the above, the following is an indicative properties chart, which illustrates the differences in the properties of different types of steel. Steel is identified by grades, which are defined by specific organizations that set standards for grading. Mild steel and two grades of stainless steel, 304 and 430 are discussed below. If you’re contemplating the best way to protect metal surfaces against the relentless forces of corrosion, a simple phrase to keep in mind is “think zinc.” When a zinc coating is electroplated onto the surface of ferrous (iron-containing) metals, it creates a formidable corrosion-resistant barrier — while also providing a number of other important benefits. In the formative years of electrical science, zinc was the most widely used metal for producing galvanic electricity. When metals are in electrical contact, one metal (zinc) will give up electrons and oxidize while the current generated will prevent oxidation of the other metal (steel).
