Metal tubes and structural sections are formed, welded, protected against corrosion and prepared to support traffic signals. Porous paper is formed, cut, pleated or crimped into disposable coffee filters, while heavy steel frames, drive systems and chains fitted with cutting teeth are assembled into machines that cut through rock and mineral deposits.
