A security door is only as strong as its frame and how the frame is fastened to the building. We build welded steel frames anchored into masonry, then hang doors with heavy hinges, pick-resistant locks and anti-pry details.
Designs range from decorative iron storm doors with glass behind, to plain heavy-gauge steel doors for basements, boiler rooms and back entrances.

Steel Security Doors & Gates FAQ
Can you build an under-stoop gate for a brownstone?
Yes — under-stoop (garden-level) gates are one of our most common brownstone jobs. We match the ironwork to the stoop railing.
Can a security door have glass?
Yes. Many security storm doors have a glass or screen panel behind decorative iron so you get light and air with protection.
Do you install the locks?
Yes, we supply and install deadbolts, lever sets and closers, or prep the door for your locksmith.
