7 good reasons to believe in ZINCALUME® steel
State-of-the-art Manufacturing Facility
ZINCALUME® steel is one of the world’s leading 55% Al-Zn alloy coated steel product, manufactured at Jamshedpur facility with plant capacity of 250,000 tpa. The facility is accredited with ISO9001, ISO14001, OHSAS 18001 certifications- a testimony to its quality and performance. Consistent and superior performance is achieved through the highest degree of automation, process control, an online inspection & testing facility- supported with well-equipped laboratory. Our coating mass control technology is amongst the most advanced in the wold. A sophisticated coating mass gauge is linked to a computer in a closed loop control system ensuring accurate control and consistency of coating mass. The consistency in mechanical properties is achieved through precise control in input steel chemistry and in-process parameters. ZINCALUME® steel has 150 g/m2 or 200 g/m2 metallic coating distributed equally on both surfaces. It is available in Base Metal Thickness (BMT) ranging between 0.30mm to 1.30 mm and coil widths of 900 to 1250 mm. It is offered with yield strength of minimum 300 MPa to minimum 550 MPa depending on the application. ZINCALUME® steel complies with AS1397, ASTM A792M, IS 15961 and ISO 9364 standards.
Decades of Proven Performance
Developed with advanced engineering, aluminium–zinc alloy coated steel offers exceptional corrosion resistance and long-term structural reliability. The unique combination of aluminium’s barrier protection and zinc’s sacrificial properties helps safeguard steel even in demanding environmental conditions. Designed for bare applications, this metallic coating enhances durability, reflects heat efficiently, and reduces maintenance. The result is a high-performance steel solution that delivers strength, longevity, and dependable protection across industrial, infrastructure, and construction uses.
A Significantly Longer Lifespan
Launched in 1976, ZINCALUME® steel, was developed after extensive research into improving the traditional performance of galvanised steel. By blending 55% Aluminium with 43.4% zinc & 1.6% Si in an alloy coating, greatly enhance corrosion resistance. As a result, our extensive testing programme indicates that life span of ZINCALUME® steel’s with AZ150 is up to four times that of ordinary galvanized steel (Z275) in similar environmental conditions. ZINCALUME® steel add Extra Life to your Buildings as compared to Z275, Z160 & AZ100.
Cool Comfort over Conventional Roofs
ZINCALUME® steel and galvanised steel perform equally, when new. But as the products weather, the thermal performance of ZINCALUME® steel is far more superior than that of identically weathered galvanised steel. When compared with fibre cement or asbestos, research has revealed an even more comprehensive performance of ZINCALUME® steel from the very first day of roof installation as ZINCALUME® steel is much more effective in keeping the heat out and offering greater thermal comfort in a new building.
Anti- Darkening Property helps Aesthetics
ZINCALUME® steel is manufactured using proven technology and durable surface treatment (coated with special passivation and resin as a separate layer). Excellent long-term exposure performance (rigorously tested in demanding conditions) and thermal reflectivity ensures that your roof and wall cladding looks newer for a longer period of time.
