Zincalume Tank

Zincalume Tank

These tanks are fabricated using the highest grade of “Zincalume Steel” as MOC, which lasts up to four times longer than galvanized steel. We use our vast industrial knowledge experience in continuous up gradation of latest software technologies to acquire supreme designs, execution capability and techniques. ROSTFREI™ efficiently proffers a wide product line to its global customers as per their specific requirements at highly competitive prices.

Zincalume steel, a premium material complies with requirements of Indian Standard – IS 15961, International Standard – ISO 9364, Australian Standard – AS 1397 and American Standard – ASTM A 792M.

Zincalume steel is manufactured by a continuous hot dipped metallic coating process. The alloy coating of Zincalume steel provides excellent corrosion resistance and has been found to possess greater resistance to cracking and peeling. Zincalume® steel has an alloy coating of 55% Aluminium, 43.5% Zinc and 1.5% Silicon. The 150g/m2 (with option of 200g/m2) coating weight is distributed equally on both surfaces of the coated strip. Metallic surface is coated with separate layers of special passivation solution and resin.



Tested Brand

Zincalume steel, the most stringent production standards ensures its superior performance and durability.

On continuous research and development, Zincalume® steel now ensures that it is able to withstand harsh environment for a longer period of time.

Sacrificial Protection

After nine months exposure under industrial marine environment conditions, Zinclaume Steel gives better performance at scribes of lower widths.

At the cut edge, galvanization steel is more susceptible to corrosion, as compared to Zincalume steel.

Durability and Safety

The base steel is coated with 55% Al-Zn Alloy with 150g/m2 coating. It combines the sacrificial benefits of Zinc with long life barrier protection.
