How an Ornamental Iron Gate Is Designed, Built and Installed
A custom ornamental gate moves through six steps: measuring, design, cutting and bending, welding, finishing, and installation. Each step depends on the one before it, so mistakes at the start show up as gaps and drag at the end.

Measuring and sketching
The work begins with the opening, the slope, and the posts. A sketch then shows the top line, the spacing of pickets, and where scrollwork or a central design sits. Full-size drawings on a flat table help, because curves look different at full scale than on paper.
Cutting and bending
Bar and tube are cut to length and bent around forms to make scrolls and arches. A scroll bent over a form repeats the same curve every time, which is what makes the left and right halves of a gate match. Hand-bending without forms gives a looser, one-off look, and some owners prefer it.
Welding the frame and infill
The frame is tacked together square first, then welded in a sequence that limits warping. Heat pulls steel toward the weld, so welding one side only twists the leaf. Pickets, scrolls, and finials are fitted after the frame is true. Every joint should be fully welded, not just spot-held, since a spot weld can crack under wind or repeated opening.
Hand finishing
Welds are ground smooth, sharp edges are softened, and mill scale is removed. This step decides how the coating will look. A rough weld catches paint thin and rusts first, while a smooth one holds an even film. Finials and tight scroll centers need hand filing, because a grinder cannot reach them.
Coating layers
A durable finish usually has several layers: a primer that bites into clean steel, one or more build coats, and a topcoat for color and sun resistance. Each layer needs time to cure before the next. Rushing layers traps solvent and leaves a soft film that scratches. Dark colors absorb Texas sun, so the topcoat should be thick and rated for outdoor use.
- Clean bare steel first.
- Prime every edge and weld.
- Build coats over curves, where film runs thin.
- Finish with a topcoat that resists fading.
Installation on the posts
Posts go in first and cure before the gate is hung. Limestone and clay both need deep footings, since shifting soil moves a shallow post. Hinges are set so the leaf swings freely, and the latch gets adjusted last. A gate hung on fresh concrete, before it cures, will lean.
Final checks
- Swing the leaf through its full arc.
- Check the gap along each post and at the center.
- Look for bare spots and touch them up on the spot.
- Confirm the latch catches without lifting or pushing.
