elZinc® : a quality brand

The use of the best technologies available on the market allows us to offer zinc quality products that exceed the requirements of standard EN 988 and ASTM B69 within which are established the specifications for flat-rolled products of zinc alloys for use in building.

The alloy is produced from zinc of the highest quality (Z1>99,995%) – according to the European standard UNE-EN 1179 – to which is added precisely controlled quantities of copper (Cu) and titanium (Ti) to improve the zinc’s properties. The alloy´s purity is closely monitored by a series of finely regulated controls.

Quality analysis

Through the optimization of the rolling process’s operating parameters and meticulous temperature control during all of the various production stages, elZinc® has developed a product of excellent quality suitable for different applications in building.

The rigorous Quality Controls continuously conducted by our own laboratories and by prestigious independent experts maintain and attest to the Quality of our material.

elZinc’s products are characterized by:

  • Very good workability irrespective of the direction of rolling.
  • High resistance to creep (creep strain limit).
  • Low cold brittleness.
  • Optimal electrowelding performance due to its low surface oil content.

elZinc : a reliable brand

All elZinc® sheets and coils are identified with a serial number to ensure traceability.

This automatic marking on the inside surface of the metal guarantees product traceability and quality of the material.

It consists of 5 segments:

  1. elZinc brand.
  2. ZnCuTi alloy.
  3. EN988 standard.
  4. The product thickness.
  5. Coil and casting identifying code.
