About us

In 1960 Manuel Concheiro and his sons Mario and Carlos founded a small company dealing with technical products for serving the Spanish industry. This space housed some of the company’s first breakthrough expertise and big ideas that would later came into the present production of Expansion Joints.

Early in the 70’s the first Expansion Joints were designed, manufactured and shipped from MACOGA.

Environmental Protection

Environmental protection is part of our corporate citizenship.

Protecting the environment is one of MACOGA’s fundamental priorities.

The dangerous toxic waste generated (oil, picklers, paint strippers, etc.) is treated in strict accordance with the Environmental Directives, 100% of our steel waste is recycled and reused in other areas of the industry, we have special zones designed to prevent certain production processes from emitting harmful and pollutant elements into the atmosphere (paint cabin and plasma cutting machinery with highly efficient purifying filters, X Ray bunker, etc.) and we have emergency plans for critical situation that imply possible environmental impact.
