Ask where the steel is cut.
A local showroom tells you where a door is sold. The workshop tells you where it is made. When you’re investing in custom steel doors or windows, ask to see both.
At D’Hierro, our own team cuts, welds, grinds, primes and paints the steel in Dallas. Our workshop is steps from our showroom. The frame taking shape on the fabrication table is the same work we’ll finish and install in your home.
That is a much more useful answer than a flag on a website or a vague promise of American craftsmanship. Ask a manufacturer what its team actually fabricates, where that work happens, and whether you can visit. We welcome those questions. We can show you the answers.
From steel stock to a finished frame.
Your door starts with a drawing and lengths of steel. We cut the material to the approved dimensions, fit the pieces, and weld the frame, door and divided-light work into their intended geometry. Hardware locations and the relationship between the opening, moving leaf and glass are worked through as part of that design.
Then comes the work you feel when you run your hand along the frame: grinding, smoothing and preparing the steel. Primer and finish follow. Glass, seals and hardware complete the assembly, and the work is checked against the approved drawing before it leaves our shop.
The crisp corner, the straight divider, the clean finish beside the glass—those details are made at a workbench. They’re exactly the details worth looking at up close.
- 01
Cut & form
Steel stock becomes the members and curves of your opening.
- 02
Fit & weld
Our craftsmen build the frame and its divisions in the shop.
- 03
Grind & finish
Joints are dressed. Surfaces are prepared, primed and painted.
- 04
Glaze & install
Glass, hardware and final fit bring the design into daily use.
Custom should mean your opening.
A great steel entrance belongs to the architecture around it. The arch should relate to the masonry. The glass divisions should align with the room. The hardware should feel right in your hand and sit comfortably within the design.
Because we fabricate the work, we can develop those decisions together. A taller pair of doors, a different divider rhythm, a slim picture window, a bronze finish beside warm stone: these are design decisions we carry into the shop drawings and the steel itself.
This matters just as much when you’re replacing an existing door. The opening, threshold and surrounding finishes are already there. We design around those conditions and coordinate the new assembly with the people working on your home. You get a door made for the project, with the details resolved before fabrication.
Compare picture glass, SDL and true divided litesThe people making it stay involved.
Custom work rewards direct communication. A question about a handle, glass division or finish can be discussed with the team responsible for making it. The design conversation and the fabrication conversation happen within the same business.
For our installed projects, our own crew carries that work into the opening. Fit, alignment, hardware operation and the finished appearance all matter. We stay focused on the steelwork from the drawing through installation, while coordinating surrounding construction with your builder or general contractor.
You know who drew it, who made it and who installed it. That continuity is one of the most valuable things you buy from a local manufacturer.
Come put your hand on the work.
A photograph can help you choose a direction. A visit lets you judge the details for yourself. Open a door. Look along the steel. Inspect a corner. Compare finishes beside the glass and feel the hardware operate.
Then walk over to our workshop and see how the product is made. It connects the finished piece in the showroom to the cutting, welding and finishing behind it. You’ll leave with a better understanding of what you’re ordering and the people responsible for it.
Bring a photograph of your home, your plans or simply a few ideas. We can talk through the proportions and possibilities while you’re standing beside the materials. Book a showroom and workshop visit at 14060 Proton Road, Suite 250, Dallas.
Dallas has been home since 1995.
Jorge and Rocio Perez founded D’Hierro in Dallas in 1995. More than three decades later, the Perez family still leads the business, bringing design and fabrication together in Dallas.
We have spent those years getting better at the work: proportion, welding, finishing, glass, hardware and installation. Our reputation is tied to what leaves this shop and how it looks and operates in your home.

Common questions.
Where are D’Hierro steel doors and windows made?
We fabricate our steel doors and frames in our own Dallas workshop, steps from our showroom at 14060 Proton Road, Suite 250. Our team cuts, welds, grinds, prepares, primes and paints the steel here.
Do you make the frames in Dallas or assemble finished imported doors?
We make our steel doors and frames here from steel stock. Cutting, fitting, welding, grinding and finishing happen in our Dallas shop. You can visit and see that fabrication work firsthand.
Can I tour the workshop before ordering?
Yes. Book a showroom and workshop visit. You can inspect finished work, compare materials and hardware, and see where our team fabricates the steel. Bring photographs, plans or ideas for your project.
Does D’Hierro also install the doors?
Yes. Our own crew installs our local projects. The installation scope is agreed with your proposal, including coordination with your builder or contractor where other work surrounds the opening.
What should I ask another steel-door company about manufacturing?
Ask where the frames are cut and welded, who does the fabrication and finishing, and whether you can visit that workshop. Ask to inspect a finished door and see installed examples as well. Those answers tell you much more than a showroom address alone.
Can you make a door to fit my existing opening?
Yes. We design custom assemblies around the opening and the result you want. Start with photographs and rough dimensions. We develop the proportions, glass, hardware and installation details as part of the project.
