COLOR COATING (PAINT)

In the Colour Coating process, chemicals and desired colour coating is applied on the steel sheet after galvalume process for making the roofing sheets. In this process, the galvanized sheets go to the relevant paint coating sections through the chemical coating process, which is backed through an oven with 210-250 degrees, to firmly blend on the roofing sheets.

PROFILING

This is the process where the straight, thin sheets are made into different profiles of roofing sheets. The sheets pass through a combination of rollers, which press against them so that they are shaped accordingly.
There are several types of finishes with smooth, bright & matte finishes to choose from which can be profiled in different profile types and lengths. The Standard length is 2 Meters, 2.5 meters, 3 meters or as per specific customer requirement.

ALUZINC PROCESS

In the Hot Dip Galvalume process, Aluminium & Zinc coating is applied on the steel sheets to prevent from corrosion and other atmospheric reactions. In this process, steel is preheated to the level of Zinc + Aluminium bath temperature for Roofing Sheet (Hard Material). For soft materials, it is annealed at above critical temperature to get desired mechanical properties. An even coat consisting of 45% zinc & 55% aluminium is applied and to maintain the coating thickness, we have automatic air gap control through PLC. Furthermore, to prevent the coated surface, it passes through chromic acid to form a protective layer. Finished coils are then sent for color coating, corrugation/profiling or direct for dispatch as is.

Quality Assurance

Our commitment to quality is unwavering. Every product undergoes rigorous testing at each stage of the manufacturing process to ensure it meets our high standards:

  • Thickness Testing: We ensure consistent gauge thickness throughout each sheet.
  • Coating Adhesion: Our products undergo bend tests to verify coating adhesion.
  • Salt Spray Testing: Products are subjected to accelerated corrosion testing.
  • Impact Resistance: We test for resistance to impact damage.
  • UV Resistance: Color coatings are tested for resistance to UV degradation.

Our manufacturing facility is ISO 9001:2015 certified, ensuring that we maintain consistent quality standards across all our operations.
