Magnum Construction


We have over 25 years experience in the construction industry.

As a member of the New Mexico Chapter of the U.S. Green Building Council, Magnum is dedicated to designing and constructing buildings that are energy efficient and environmentally friendly. What makes steel green? Consider these features:

70% of the steel used in the construction industry is made of recycled material. Since 1990, the steel industry has reduced its CO2 emissions by more than 20%. Steel does not contribute to indoor air pollution by off-gassing or releasing chemicals into the indoor atmosphere. Steel is readily reused and/or recycled when buildings are demolished. Structural members are available that include thermal breaks, making steel more energy efficient than wood. Combined with our other environmentally-conscious practices, steel construction allows Magnum to provide green building services to help make sure our customers’ projects are both economical and ecologically friendly.
