5mm Mild Steel Sheet

What is IZ? A dream for welding and painting Iron Zinc (IZ), gets its name from the iron zinc alloy it is coated with. Even though it has the same centre as galvanised, the different coating gives it a whole new bunch of properties and allows it to be specialised for different applications. IZ or galvanneal as it is sometimes referred to, provides a matte and consistent grey coloured finish and is more brittle and harder than galvanised. Its welding, bending and forming ability make it a favourite within the car and door manufacturing industries, and it's also loved for being an excellent, scratch-resistant base for paint. The IZ coating, also known as a galvannealled coating, is different to others because of its 10% iron content. That little iron content increases its resistance to corrosion and combats corrosion of the steel underneath, making the entire sheet last even longer than standard galvanised steel. Don’t forget we also cut to any size, so whatever size you require, we’ve got it covered. Good for: Creating high quality painted products, car parts, spot welding, welding, forming, security doors and many more. Thanks to its welding and painting properties, iron zinc’s most common usage is for car parts. How it’s Made: IZ (Iron Zinc) is created when steel is immersed in a bath full of zinc until an alloy coating between the zinc and steel forms. After being removed from the bath, gas knives are used to wipe away the excess coating, and this is how different thicknesses are made; the coating is wiped down until the required thickness is met. Once coated in molten zinc and at the right thickness, the steel is taken to a furnace, heated between 1000-1500°F, and kept there until the molten zinc becomes fully alloyed with the iron from the steel. The outcome is the extremely tough IZ steel, coated with an alloy of zinc and 10% iron. Benefits:

• Strong
• Perfect for high quality painted products
• Extremely resistant to corrosion & scratches
• Great for welding applications

Random Fact Magnitogorsk, a mountain in Russia, is the only mountain in the world that is almost completely made up of iron, with around 7-10 Billion pounds of Iron Ore. For IZ (Galvanneal) products please contact Sara, Jess, Rosey or Rebecca on sales@buymetalonline.co.uk or 0191 2646464.
