Galvalume — also known as Zincalume — is a high-strength steel sheet coated with an alloy of 55% aluminium, 43.4% zinc, and 1.6% silicon. Developed in the 1970s, it has become one of the most widely used materials for long-lasting industrial and water storage applications worldwide. At Al Karwan Solution FZC, we use certified Galvalume/Zincalume steel panels as the core material for our premium sectional water storage tanks across the UAE.
The synergistic combination of aluminium and zinc provides benefits that neither metal can achieve alone:
The result is a coating system that lasts 2-4x longer than standard galvanised steel in most environments — including the UAE's harsh combination of extreme heat, UV radiation, high humidity, and occasional salt-laden coastal winds.
The UAE presents one of the most challenging environments for metal structures on earth. Summer temperatures regularly exceed 45°C, and the combination of UV exposure, humidity, and salt air in coastal areas like Dubai, Abu Dhabi, Sharjah and Ajman can cause inferior materials to corrode rapidly. Zincalume steel is specifically engineered for exactly these conditions.
In independent corrosion testing, Galvalume/Zincalume has demonstrated a service life of over 25 years in industrial environments — far exceeding standard galvanised steel or painted mild steel.
Our sectional pre-engineered Zincalume water storage tanks are manufactured using certified 55% Al-Zn coated steel panels, factory-formed to precise dimensions and delivered to site ready for rapid assembly. Each tank features:
Galvalume steel is 100% recyclable at end of life, making it one of the most sustainable material choices for large-scale water storage infrastructure. Its long service life also means less frequent replacement — reducing the environmental impact associated with manufacturing, transport and installation.
When investing in a water storage tank for a UAE project, the material specification is the single most important factor determining long-term performance and total cost of ownership. Al Karwan Solution FZC's Zincalume steel tanks deliver decades of reliable service, backed by our full installation and warranty support.
