In an era of recycling and cost-cutting, many roofing manufacturers use “secondary” or “scrap-based” steel to produce color-coated sheets. While this might look the same on the surface, the molecular structure is compromised. At Kanakdurga Technokraft India, we start with a simple, non-negotiable rule: KD Sheets are made from Pure Steel.
The Problem with Scrap-Based Steel
Steel made from melted scrap often contains “trace elements” or impurities that cannot be fully removed. These impurities create “weak spots” in the sheet. Under the intense heat of the West Bengal summer or the heavy pressure of a cyclone, scrap-based steel is prone to:
-
Micro-Fracturing: The steel snaps at the bends.
-
Inconsistent Tensile Strength: One part of the sheet might be strong, while the other is soft.
-
Internal Corrosion: Impurities act as magnets for rust from the inside out.
The KDT Pure Steel Standard
By using virgin, pure steel, KDT India ensures maximum strength for every sheet. This purity is what allows us to guarantee a yield strength of 550MPa to 770MPa. When the steel is pure, the Al-Zn coating bonds more effectively, and the Superior Paint Technology adheres without peeling.
Conclusion
A house is only as strong as its foundation, and a roof is only as strong as its steel. When you buy a KD Sheet, you aren’t just buying a color; you are buying the chemical purity of high-grade steel that protects your life and property.
