How to Tell a Well Built Iron Gate From a Poor One

A snow-covered alleyway in Hartford, CT with a brick building and wrought iron gate.

Within a mile of the marine layer in Carlsbad, CA, two quotes for ornamental iron work can look identical and still age very differently, and the checks, as laid out at ornamental iron gates carlsbad rex theater galax, start with how the joints were made. Salt and overnight moisture find every gap. The work to judge is the weld, the sealing and the coating, not the size of the bar.

Continuous welds against tack welds

A continuous weld seals the joint. Tack or stitch welds leave small crevices where water and salt collect, and rust starts there and spreads under the finish. Look at where pickets meet rails and where the frame corners close. A bead that runs the full length of the joint is what to want. Heavier stock does not make up for open seams, and heavier does not always mean better built.

Hollow tubing and drainage

Steel tubing rusts from the inside if water gets in and stays. Hollow members should be fully sealed, or drilled with drain holes at the low points so nothing sits inside. Pickets that pass through rails with sealed joints resist water entry better than open punched holes. Check the bottom rail especially, since that is where water ends up.

Edges and coating coverage

Ground and blended welds take coatings more evenly than rough beads with sharp edges, because paint and powder pull thin off a sharp edge. Then inspect the places coverage is most often thin: inside corners, the backs of scrolls and the underside of rails. A glossy finish proves nothing about corrosion protection, and ornate scrollwork says nothing about quality. Coverage in the hidden spots tells more.

Frame, sag and hinges

A swing gate leaf wants to drop at the latch end. A diagonal brace or a stiff frame shows the builder planned for that sag. Hinges should be sized to the leaf weight and ideally greaseable, since a hinge that can be serviced wears more slowly. Along the coast near Agua Hedionda Lagoon or in Encinitas, a dry hinge with salt in it will bind well before the gate itself shows any wear.

Questions for the fabricator

Ask what finish system is used. Galvanized steel with powder coat over it behaves differently from bare steel that is only primed and painted. Then ask how fabrication, cleaning and coating were sequenced. Welding after coating burns the finish off the joint, and coating before the surface is cleaned traps contamination under it. A fabricator who has done this work can answer in a few plain sentences, and the answers are worth comparing quote against quote.
