The metal roofing in Chennai, uses a different combination of raw materials for better resistance according to the environmental condition.
The coil goes into the coil coater where Kynar 500 or Hylar 5000 coating system is applied. The substance is placed on a continuous coating line where it is cleaned and specially treated with paint and baked at a high temperature. At the end of each coating of paint, it is checked for quality assurance. The redundant check is also done before reaching the manufacturing process by quality assurance engineers.
The third step in the process is allowing the metal coil to run into the roller former. A roller former plays a vital role in turning the metal coil into metal sheets and panels. The purpose of running the metal coils into a roller former is to reduce its thickness and achieve the desired grade. The shape and bend in the material are attained by the successive roll of the roller. The width of the sheet is adjusted manually as per the design.
Computer control unit:
The metal roofing in Chennai uses a computer control unit to make changes in speed, control, operation, and panel length. The mill engineers adjust the roller machine and cutting of the panel at a specific length.
The product is immediately inspected for its color, appearance, and quality. Once the sheets pass the quality check they are packed carefully to transit so they can be installed on your roof for a lifetime.
The remnants are collected, bundled, and sold back to the mill to and re-used as metal coils. These scraps are re-used in the manufacturing process continuously for better results.
