Our commitment to the customer is paramount. We work together in the development and improvement of our products based on their specific needs, guaranteeing they consistently receive high quality, durable architectural zinc.

One of the main characteristics of titanium zinc is its high resistance to corrosion. Produced using cutting edge technologies and according to a rigorous quality protocol, elZinc® is of exceptional quality.

The lifetime guarantee we offer – unique in the sector – reflects the reliability of our elZinc Astur® and elZinc Slate® finishes. With more than a decade on the market, we have accredited their quality, solidifying our commitment to our customers.

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


ISO 9001

From its origins, Asturiana de Laminados, SA – elZinc® – has submitted itself to an ongoing process of improvement that has been accredited and endorsed by the internationally recognized standard for quality management UNE-EN ISO 9001.

elZinc®’s main concern and objective is to give our clients total satisfaction right from the time we first make contact.


elZinc® has been awarded the prestigious Dutch KOMO certificate for its rolled products elZinc® Natural, elZinc Slate®, elZinc Rainbow® and elZinc Graphite®. This certificate, which follows a strict validation process, certifies that all elZinc® processes and products comply with the company’s strict control measures to ensure the highest quality.


The CE Marking for Construction Products is compulsory for all products that are covered by a Harmonised European Standard, or show the European Technical Assessment, and that are sold within in the European Union. The CPP is a unique and directly applicable regulation which provides a common model recognised by all the local authorities and administrations, but is not transposed into the EU member states.

In respect and support of this measure, elZinc provides all its clients with the declarations of performance according to EN14782 and EN14783 standards.
