Commercial Pre-Engineered Steel Buildings

Steel has been used in the construction of buildings since the early 20th century. As construction techniques and materials have evolved, steel has become the preferred alternative for many types of commercial buildings. In a time of environmental concerns, steel is one of the greenest building materials available. It is essentially 100% recyclable and is the world’s most frequently recycled metal. Construction is less energy intensive due to the use of prefabrication techniques.

Commercial Wood Buildings

As a Design-Build firm, J.M. Brown General Contractor often uses wood to fulfill customer needs. We have been building wood structures since 1996, and have much experience and expertise to offer.
