Who are we?

Our company is people, and people are its greatest value.

The roots of ALSTE date back to the 1990s. Backed by its its owner’s and managers’ unrivalled expertise in metallurgy and welding, our company can guarantee the precision and timeliness that fully meet the industry’s established standards.

For over a decade, we’ve had the opportunity to explore our business environment and choose the best partners. The hot-dip galvanizing and paint shops we cooperate with use only top-quality materials, completing every job with extra care and right on schedule. Steel suppliers provide us with the best, certified products. We will deliver any prefabricated items to the destination of your choice, safely and on time.


As every construction site, we keep changing as well. Responding to what’s needed here and now, our vision reaches into the future. We are a company which, acting as the Project Owner or General Contractor, can be entrusted tasks of any size and complexity.

We are prepared for that. We are ALSTE.
