Commercial Doors, Frames, and Hardware for Contractors. Walk-In, Will-Call, and Small Jobs

Large in-stock inventory across commercial metal doors and frames, with quick turnaround and in-house modification when your job needs more than stock.

We are a commercial general contractor and we use Houston Starr for most of our doors. They have a great PM, Jason Morgan, who goes the extra mile to make sure the order is correct and on time. He has done numerous site visits and his efforts have saved us a lot of money in install time. I highly recommend!

  • Counter staff who speak the language of hollow metal, frames, preps, and hardware coordination
  • Stock-driven answers when you’re trying to close out or keep a crew busy
  • Modification and customization when “stock” isn’t quite right
  • Walk-in and will-call workflows that respect small orders, not just large releases

What You’ll Find in Stock

We maintain a broad commercial inventory including hollow metal doors and frames to the metal door types and frame styles contractors ask for most often.

Bring This to the Counter

  • Quantity, rough opening or nominal size, and handing / swing where it matters
  • Door or frame type: hollow metal, KD vs welded frame, and any relevant detail you’re matching

  • Photos or markups if you’re troubleshooting a field condition

Frequently Asked Questions

What’s the difference between welded and knock-down frames?
Welded frames arrive as a welded assembly built to the opening detail you’re working with. Knock-down frames ship in pieces for field assembly — often helpful when access, timing, or logistics make a welded frame harder to work with. If you tell us the opening and the detail, we’ll steer you toward what fits.
Yes — the counter is built for walk-ins, will-call pickups, and smaller quantities, not only large releases. If you’re not sure what you need yet, call ahead and we’ll help you narrow it down before you drive over.

Hollow metal is a core commercial line for us, and we also stock other commercial metal door types contractors commonly need. Ask at the counter for what’s available for your spec and timeline.

It depends on what you need and whether modification is involved. Many common sizes and configurations move quickly from stock; your counter rep will give you a straight answer once they see your detail.

Five Star Reviews From Our Customers

"Highly Recommended"

We recently worked with Houston Starr Company on a commercial door replacement and upgrade project for our facility in the South Side of Pittsburgh. From the initial meeting to the final installation, the entire process exceeded our expectations. Phillips Heating & Air Conditioning had two new doors and upgraded a third, ensuring seamless integration with the new key fob entry system we implemented at the same time. Their professionalism, expertise, and attention to detail made the project smooth and efficient. Overall, we couldn’t be more pleased with the outcome and would highly recommend Houston Starr Company to anyone in need of commercial door solutions.

"Very Professional"

I have worked with and purchased products from them for a number of years. I am pretty sure that I’m not their biggest customer but they treat me as if I am. The sales staff and customer service is courteous and prompt. Deliveries are on time and easy to deal with. From top to bottom, this is a class organization and a pleasure to do business with.
