SPEEDO Autoblast Q6930 is the most appropriate surface treatment equipment for blasting raw steel plate external surfaces available in the surface preparation industry.

The equipment is capable of providing the necessary blasting standards by removing surface rust, weld seams and oxidized surface through its powerful wheel blast systems.

The blasted surface will not only remove rust and unnecessary attachments on the metal surface, it also creates a profile, which increases the adhesion performance of the paint coating applied.

This machine is specifically designed for raw material steel plate blasting at an economical package to meet the investment returns for clients in need of meeting their plate & profile treatment operations. It has served a wide range of industries ranging from Heavy Steel Fabrication, Rail Tracks, Engineering Construction, Bridge Construction, Marine and Offshore etc.
