Ervin can come to your assistance if you require world-class steel shot blasting solutions. Steel shot blasting is the ideal surface preparation method and is commonly used to remove sand, scale, rust, oxide, previous coatings and more. Steel shot blasting goes by many different names and is also referred to as shot blasting and abrasive blasting. The process often takes place in a blast room and automatic wheel machine and can be used to clean, strengthen and prepare metal. Surfaces can also be cleaned with grit before they are coated. Shot blasting is an environmentally friendly option that is used in a wide range of industries including the automobile sector, aerospace, rail and many more.
Steel shot blasting ensures scale, rust and other coatings are completely removed from a surface so new coatings can adhere to the steel. You can expect the coating to fail unless it is added to a clean and properly prepared metal surface. In steel shot blasting, steel is fired against the surface with compressed air or by machine blasting. Steel shot blasting is ideal for cleaning, smoothing and roughing a surface. The shots are delivered at high velocity so the right results can be achieved.
During the process, small particles between 0.125-3mm in diameter are propelled against the surface. The bigger the pellets are, the rougher the surface will be. Opting for smaller shots will give you a smoother and more polished finish. Chilled iron grit can be used for certain metals but is not a suitable match for softer surfaces like aluminium. There are two main shot blasting technologies in use today, and these are wheel blasting and air blasting.
Ervin can help you achieve shot blasting solutions of the finest calibre. We have a century of experience behind us, having been first founded by John F Ervin in the early 1920s. The company remains in the family, and this is just one of many reasons why so many clients and customers choose us when they require shot blasting solutions from a brand they can depend on.
