💡 A Word from JOBPLOY
Since the work mainly involves handling metal plate products such as duct manufacturing, processing, assembly, and loading, wearing protective gear like safety gloves and strictly following on-site safety rules is very important. As the work may include heavy lifting or mechanical processing, it is desirable to maintain basic physical strength, collaborate with colleagues, and ensure smooth communication regarding work signals.
