Design/Build Process

Phalen Steel Construction Company is a Design/Build, General Contracting company having in-house architectural services licensed with the State of Illinois. This feature makes our firm unique in our trade area. We are equally proud to say that we have represented Butler Manufacturing Company, the leader in the pre-engineered metal building industry, in North Central Illinois since 1948, making us their oldest builder in the nation. We also have a Career Buildership which is only offered after proven capability. We were also recently the recipient of Butler's highest award: Builder of the Year.

Being a Design/Build, General Contractor enables us to provide the owners with a single source of responsibility, the number one pre-engineered building in the industry and one of the largest product lines available. All these products are entered into our computer and available to be combined and priced in multiple fashions to arrive at the most functional and competitive designs.

Our Butler products are renowned for their vast array of products produced with quality and expansion and contraction in mind. These products include the nationally acclaimed pre-punched purlin and panel system, and the best standing-seam roof on the market (MR-24). Butler roof systems are capable of carrying an installed rating from Underwriters Laboratory of Class 90, the highest available, enabling you to lower your insurance rates while at the same time helping to ensure weather tightness.

Most single story and many multi-story projects today, do take advantage of pre-engineered construction, because of economies and rapid shell construction. We want to make it clear, however, that we are not confined to only pre-engineered construction. We have for many years Designed and Built a number of grocery stores, supermarkets, food processing and storage facilities, schools, dormitories, churches, strip centers, mini-warehouses, sports centers, manufacturing facilities, hospitals, medical clinics, nursing homes, banks, office complexes, and many other construction projects using conventional steel, precast, masonry brick and block, and wood components.

These quality materials are complemented by the 30 years average tenure of our foremen, a 14 person Design and Build office staff, and a 4 generation, 70 year commitment to perform to the highest standards of workmanship.

We at Phalen Steel Construction Company are truly interested in your project, and look forward to the opportunity of working with you. To contact us simply double click below and drop us a line.
