Swirnow Building Systems®…Building On Experience®

For over 50 years, Swirnow Building Systems has been building success stories with designers, builders and developers like you. This remarkable track record is the result of hard work and our belief in getting things right the first time. We have extensive experience in innovative Structural and Architectural building solutions, and we are proud to be associated with some of the most popular building systems in America, including Hambro® Structural Floor Joists.

In 1972, we became the first licensee for Hambro Structural Floor Joists in the United States. Combining composite steel joists with concrete, Hambro is one of the most advanced floor systems on the market; its pedigree has been copied, but never matched. Beginning in the early 1970’s, Swirnow Building Systems secured all the major U.S. code approvals for Hambro and initiated rigorous fire testing programs, making Hambro’s fire ratings some of the best in the industry. Today, Hambro has been used on hundreds of millions of square feet, on a variety of projects throughout North America.
