In 2016, Abul Khair Steel embarked on a new industry benchmark by pioneering the production of Zinkalum using cutting-edge American technology. Zinkalum stands as a superior metallic-coated steel product in the market. It has impressively demonstrated its exceptional corrosion-resistant properties through extensive field-testing in diverse environmental conditions. Its global acceptance is a testament to its remarkable versatility, user-friendliness, aesthetically pleasing attributes, and long-term performance reliability.
The production process involves a state-of-the-art hot-dip aluminium and zinc coating method, expertly blending 55% aluminium, 43.5% zinc, and 1.5% silicon to achieve optimal material composition. This unique combination bestows Zinkalum with unparalleled strength, ductility, and remarkable resistance to corrosion. Its remarkable bonding between the steel sheet and aluminium-zinc-silicon coating ensures freedom from blistering and paint adhesion issues.
- Longevity is 2 to 4 times higher than any other ordinary steel sheet.
- Provides an oil-free surface due to the application of a clear organic coating to both sides of the sheet.
- It is stain resistant and remains free from fingerprints and smudges.
- Its roll-forming capability without additional lubricants streamlines the manufacturing process, thereby enhancing cost-efficiency.
- High temperature resistance (can withstand a prolonged temperature of 315 degrees Celsius without discoloration or oxidization).
- It is highly energy efficient, with superior heat reflection capacity.
- It is available in a silver-bright matte surface.
- It is easily paintable, workable, weldable, and formable.
In summary, with the help of innovative hot-dip aluminium and zinc coating processes and the application of a clear organic coating, Zinkalum has been elevated to the market leader of building materials. Its outstanding performance and visual appeal have garnered widespread acclaim, establishing it as a reliable, durable, and aesthetically pleasing choice for diverse construction applications globally.
