How Custom Iron Gates Are Cut, Welded and Finished

t278-20

A custom iron gate is made by measuring the opening on site, drawing the gate to that exact size, then cutting and welding the steel frame and infill in the factory. The finished gate is hot-dip galvanized or powder coated for protection and then installed and adjusted at the property. Each stage builds on the previous one, so accurate measurement at the start is what makes the final gate fit and swing properly.

Starting With an Inquiry and Site Photos

Every custom gate begins with a simple inquiry. Send photos of the opening, the wall or posts on each side, and the surface where the gate will swing. Photos help us understand the terrain, whether the ground slopes, and what sits near the gate, such as a planter, a step or a driveway edge.

It also helps to tell us how the gate will be used. A pedestrian gate has different needs from a vehicle gate, and a gate that opens onto a slope behaves differently from one that opens onto flat ground. These details shape the design before any measuring is done.

On-Site Measurement Before Anything Is Cut

Measuring on site is the most important step in the whole process. We check the width and height of the opening at the top, middle and bottom, because walls are rarely perfectly square or level. Posts are checked for plumb, and the swing path is checked for clearance.

Opening width at three heights
Height from the ground to the lintel or top of the post
Ground slope and any obstructions in the swing arc
Position and type of hinges and latch

Small differences of a few millimeters matter, so we record every figure before we leave the property.

Drawing and Written Specification

Once measurements are taken, the gate is drawn to scale. The drawing shows the frame profile, the infill pattern, the position of hinges and locks, and any decorative elements. A written specification lists the materials, the finish and the installation method so there are no surprises later.

We share the drawing with the client and wait for approval. Changes at this stage are quick and inexpensive. Changes after cutting and welding are much harder, so we treat approval as a firm checkpoint before production starts.

Cutting and Welding in the Workshop

In the factory, steel sections are cut to length according to the drawing. Frame members are then assembled on a flat jig, which keeps corners square while they are welded. The infill bars or decorative pieces are positioned and welded in place, and the frame is checked against the drawing as work progresses.

Welds are ground smooth where they will be visible and where they might catch the hand. The gate is kept flat and square throughout, since a gate that is out of square will drag or sag once it is hung.

Finishing: Galvanizing and Powder Coating

Iron rusts when exposed to moisture and air, so finishing is essential. Many gates are hot-dip galvanized, which coats the steel in a layer of zinc that protects it from corrosion. After galvanizing, the gate is often powder coated in the colour the client chooses, which adds a durable and attractive surface.

Surfaces are cleaned and prepared before coating so that the finish bonds well. Galvanizing and coating are done by specialist partners, and the gate is inspected when it returns to the workshop.

Installation and Final Adjustment

On installation day, the posts or hinge points are checked again against the gate, since site conditions can shift slightly. The gate is hung, the hinges are aligned, and the latch and any lock are fitted and tested. We check that the gate swings freely, closes fully and does not rub the ground or the post.

Final adjustment is made on site so the gate operates smoothly in daily use. We walk through how the latch works and point out anything that needs care, such as keeping the swing path clear.

Frequently asked questions

How long does the custom iron gate process usually take?

Timing depends on the size of the gate, the finish chosen and the current workload. Each stage, from measurement to installation, is scheduled so the client knows what to expect at every step.

Do I need to be home for the measurement?

It helps if someone who knows the property is present, since they can point out the swing path, the position of hinges and any obstacles. It is not strictly required if photos and clear notes are provided.

Can I change the design after the drawing is approved?

Changes are possible before production starts, and they are usually simple at the drawing stage. Once cutting and welding have begun, changes are much harder, so reviewing the drawing carefully is important.

Why is galvanizing used on iron gates?

Galvanizing coats the steel in zinc, which protects it from rust even if the surface is scratched. Combined with a powder coat, it gives long-lasting protection for gates exposed to weather.

Common mistakes to avoid

A common mistake is measuring only once or in one spot, which misses walls that are out of square or uneven ground. Approving a drawing without checking the swing path and the hinge positions can also lead to a gate that rubs or does not close fully.

Our recommendation

Measure the opening at three heights and check the swing arc for obstacles before ordering, and share those figures with the workshop. Ask for the drawing in writing and confirm the finish so the gate you receive matches what you approved.

Summary

A custom iron gate is built from careful on-site measurement, an approved drawing, precise cutting and welding, protective finishing and a final installation check. Each step protects the fit, strength and lifespan of the gate.
