Shop for a front door long enough and you'll see “wrought iron” and “steel” used like they're the same thing. They're related, but the differences matter for how your door looks, weighs, insulates, and ages.
What people mean by “iron doors.” Traditional wrought iron doors are built from solid iron bars and scrollwork, forged and welded into a frame that holds glass panels. The look is unmistakable — depth, shadow lines, and hand-worked detail you can't stamp out of a sheet. Most of what's sold today as “iron doors” is actually a hybrid: a steel frame and skin with forged iron detail where you see it. That's a good thing — you get iron's look with steel's consistency.
What steel doors are. Modern steel doors are fabricated from steel sheet and tube — cleaner lines, thinner sightlines, lighter weight. If you want the minimal, glass-heavy modern look (like our SD-100 series), steel is what makes those thin frames possible.
Weight and hardware. Either material outweighs a wood or fiberglass door by multiples. That's why hinge quality, frame engineering, and correct installation matter more than the iron-vs-steel question itself — a well-built heavy door swings with one finger for decades; a badly hung one sags in a year.
Insulation. Metal conducts heat, so the glass and construction do the insulating: dual-pane glass, thermal breaks where appropriate, and proper weatherstripping. Ask any door seller what's between the panes and how the door seals — if they can't answer, keep walking.
Rust. Bare iron rusts; properly galvanized and finished doors don't. Every Ironclad door is galvanized and hand-finished in multiple coats before it ever sees weather.
Which should you choose? It's a design question more than a durability one. Ornate or traditional home: iron detail. Modern build: steel simplicity. Both, built right, will outlast the house around them. Send us a photo of your entry and we'll tell you what we'd build — free quote, next business day.
