Why Are Defender’s Steel Entry Doors in Chicago Superior To The Competition?

Defender’s Chicago steel entry doors showcase beauty while providing unmatched strength and security at the same time.

While most steel entry doors in Chicago are created using 24 or 26-gauge steel, Defender steel entry doors are made using 22-gauge steel, making them 30% to 60% stronger than most doors on the market.

All of our doors come in a wide variety of finishes as well. You can choose from a painted finish or wood grain stain. All doors are zinc galvanized, primed, and then painted and baked. This gives every Chicago steel door a beautiful finish that is durable enough to last for many, many years.

Defender’s wood grain steel doors are made with full grain and come architecturally styled and railed to replicate the appearance of a natural wood door.

We also use magnetic weather stripping on all steel entry doors for maximum energy efficiency. This allows your door to seal airtight, just like a refrigerator. The adjustable threshold also seals the bottom of the door preventing under-drafts. Our polystyrene core gives every door an outstanding R-Value of 15.1 for truly superior energy efficiency. This makes our steel doors Chicago perfect for our climate!

Defender also allows for each steel door to be installed with a steel frame to maximize security or for the door to come pre-hung on a new jamb. This allows us to adapt to the type of installation that meets our customers’ needs.

We are proud to offer steel doors of the highest quality and have been doing so for 30 years throughout the Chicagoland area.
