preengineeredPence Construction is one of the leading pre engineered steel building contractors in Southern California. We understand that every building project is unique, and that each customer has special facility requirements; from interior clear heights, to building width and length. And pre-engineered steel buildings are capable of meeting the needs of the most demanding facilities. Each of the pre-engineered steel buildings that we erect is designed from scratch—customized to meet your needs and demands. We are a Varco-Pruden metal building dealer, and have direct access to the most advanced computerized engineering system in the industry. This allows us to design and detail every aspect of your building here at our office. We are able to control the design and estimating functions simultaneously, which saves our clients valuable time and money.
