About Us

We offer unsurpassed customer service, along with professional consulting and design services, for one-of-a-kind award-winning projects.


We’re a full-service provider of custom, metal windows and doors.

At Steel Windows and Doors, our backgrounds range from construction management to architecture – this combination of knowledge and hands on experience sets us apart as we help facilitate projects by working with you to develop all of the details starting with the design, to surround and waterproofing details, as well as structural requirements, through installation.

We’ve been distributing since 1996, and today offer a wide range of products from the top manufacturers of steel: galvanized and stainless steel, brass for a bronze finish, and Corten. We are much more than just a sales office, we have extensive hands-on experience and the technical knowledge needed to help our customers choose the products that will exceed their needs. Our in-office CAD capabilities offer quick turnaround time for any drawing needs from sketches to designs.

Your one source solution: In addition to our luxury metals, we now offer aluminum, wood, and fire-rated windows and doors to complete your custom building project.

Steel Windows and Doors USA is owned and operated by Bill Polinsky and Domenick Siano. Prior to starting the company, Bill and Domenick worked with the original steel window manufacturer Crittall, and owned and operated a residential construction company that focused on high-end building and remodeling with special attention to detail and customer service. Their observation of the rising need and demand for high quality steel windows and doors led them to open Steel Windows and Doors USA as a unique, service oriented company. Both Bill and Domenick have extensive education and practical experience in the industry and can frequently be seen visiting job sites to ensure that the finished product exceeds their clients’ expectations.
