Here at Progress, we offer in-house sandblasting services. This method of surface preparation is a key step to remove surface contaminants in the pre-treatment process before the galvanizing of certain materials. These materials include those of which are painted, severely rusted, as well as those coated with certain machining lacquer or grease. In 2017, a new manual blasting chamber was added to join our existing automatic sand blasting line, catering to diversified needs.
