Product Description: QH69 series of roller-type steel, shot blasting machine components can be justified on the steel structural components and size of a one-time adoption of clean-up. Not only can remove the workpiece surface rust, clean off the welding slag on the structural parts, you can also eliminate parts of the welding stress and improve fatigue resistance workpiece to increase the workpiece when the paint film adhesion and, ultimately, improve the surface and internal quality purposes.
Uses: Used H-beam and other structural parts of the surface cleaning.
