Galvalume® - ArcelorMittal Tubarão


Galvalume® (GL) – basic composition: 55% aluminium, 43.4% zinc and 1.6% silicon. The combined action of the aluminium and the zinc gives extraordinary corrosion resistance to this type of coating, where the first creates a protection barrier whilst the latter becomes the sacrificing element providing galvanic protection. Among its most important characteristics are high reflectivity, which generates higher thermal efficiency, and high heat resistance with no loss of protection, brilliance and colouring characteristics.

The fine oxide layer created by the aluminium makes the surface looks better and shiner when compared to other coatings and which combined with its good resistance to abrasion and higher surface hardness make Galvalume® an ideal option for outdoors applications and more aggressive to corrosion. Galvalume® is mainly used in construction (roof tiles, facades, warehouse side closing, troughs, and steel framing), white line products (dishwashers, fridges, microwave ovens), agriculture (silos, storage warehouses), and other segments (air ducts, electrical panels, computer cabinets, electrical purley).

The types of coating supplied for this product are:

  • Comfort in the car seat - ArcelorMittal Tubarão

    Comfort in the car seat

    Under the cushion of a comfortable car seat there is a complex steel structure and a good chance it has been produced by ArcelorMittal.

    Our steel is also used in the structure that adjusts the seat, the lock that prevents it from sliding and the rails where the seat is mounted.

  • Lighter and higher strength - ArcelorMittal Tubarão

    Lighter and higher strength

    In order to beat the challenge of manufacturing safer and more economical cars, the world automotive industry counts on the supply of lighter and higher strength steel. This way, the new cars spend less fuel because they are lighter, but have safer structures to protect the people.

    ArcelorMittal Tubarão, together with Vega, has become one of the main suppliers of the Brazilian automotive industry by offering steel with these characteristics.

  • Outstanding for quality and longevity - ArcelorMittal Tubarão

    Outstanding for quality and longevity

    ArcelorMittal Tubarão Blast Furnace 1 is considered a steel industry landmark for its longevity and quality. Started-up in 1983 with a revamping forecast for 1991, the equipment had its lifespan stretched to 2012 beating all world records. In 2013, after its first revamping, it returned to operation at its regular levels of quality and productivity.

  • Cleaner transportation - ArcelorMittal Tubarão

    Cleaner transportation

    The creation of the Ocean Barge Terminal made it possible for ArcelorMittal Tubarão to use cabotage as a means to transport coils to the São Francisco do Sul port where ArcelorMittal Vega is located.

    The capacity of each barge is approximately 5 thousand tons of steel. Besides gains in efficiency the barges make it possible to avoid road transportations reducing CO2 emissions.

  • Expanding capacity - ArcelorMittal Tubarão

    Expanding capacity

    Started-up in 2002 as one of the most modern plants of the world steel industry, the Hot Strip Mill (HSM) in Tubarão has never stopped to evolve. Continuous investments in improvements and the implementation of the second reheating oven the HSM has more than doubled its production capacity going over the original forecast of 1.8 million tons to produce more than 4 million tons in 2013.

  • Technology for construction - ArcelorMittal Tubarão

    Technology for construction

    One of the segments which have largely increased the use of steel is construction. New technologies make it possible to make better use of characteristics such as durability and resistance to build houses and buildings faster and with more quality.

    ArcelorMittal Tubarão has contributed to steel use development in construction by supplying customized products and services to the sector.
