Pre-engineered metal buildings are custom-engineered, high-quality metal building systems for commercial, industrial, institutional, recreational, aviation, and many other specialty applications. On average, custom metal buildings cost less than conventional construction — often up to 30% less. Optimized processes greatly reduce the time to design, produce, fabricate, and erect metal buildings. When more space is needed, metal walls and framework are simple to remove for easy and seamless additions to existing metal buildings. Steel building systems can contain over 70% recycled steel and are 100% recyclable.
