Abrasive Blasting Media

Remove paint, coatings, and rust or add texture to surfaces. This media is suitable for use on a wide variety of surface materials.

Our abrasive blasting materials are sorted from least to most aggressive. The more aggressive the media, the more material it removes from your surface.

Both particle mesh size and grit measure the size of the abrasive particles. The higher the number, the finer the particles are.

Steel Shot

The most common abrasive for heavy duty cleaning and peening jobs. Rounded like glass but harder and denser, this shot blasts away heat-treated scale, heavy forgings, and other stubborn irregularities while leaving a uniformly peened finish. It also lasts for 500 times more cycles than glass, so it’s perfect for abrasive blasting cabinets and other systems that let you reuse your media.

High Reusability—Effective for hundreds of cycles under normal blasting conditions.

Steel Cut Wire Shot

A tougher alternative to steel shot. Cut from cold-drawn solid steel wire for extreme durability, this media stays effective for twice as many cycles as steel shot. The cutting process forms both rounded and sharp sides, so it will peen and etch your surface at the same time. It also creates highly consistent pieces for a uniform finish.

Very High Reusability—Effective for thousands of cycles under normal blasting conditions.

Steel Grit

A more aggressive alternative to steel shot, steel grit blasts harder and leaves a rougher finish thanks to its sharp, angular edges. It digs below the surface to remove material, which is why it’s commonly used to strip paint, remove rust and scale, and prep surfaces for coatings to bond to. However, you should only use it on steel and iron surfaces because it will leave iron behind that could contaminate other materials.

Medium Reusability—Effective for dozens of cycles under normal blasting conditions.
