A TR4 TR5 machine refers to a type of cold roll forming machine used to manufacture metal roofing sheets, specifically creating TR4 and TR5 profiles (Trapezoidal Roof profile 4 and 5), which are popular for industrial and residential buildings due to their strength and aesthetic appeal, often forming double layers (TR4/TR5) for efficiency in a single machine. These machines take flat steel coils, feed them through a series of rollers to shape them into the desired corrugated or trapezoidal pattern, and then automatically cut them to length, all controlled by PLC systems.
