3. Customization Different construction projects often require purlins of varying sizes and shapes. Purlin roll forming machines offer customization options, allowing manufacturers to produce purlins according to specific design requirements. This adaptability is a significant advantage, as it meets the diverse needs of different architectural styles.
- High-Frequency Electric Resistance Welding (ERW) In this method, electrical currents are passed through the edges of the metal strips to heat them, allowing them to fuse together under pressure. This technique is highly efficient and produces a continuous weld along the length of the pipe.
