How to Judge the Quality of Metal Gate Work
The paint is supposed to show how good a gate is. Often it only hides what the weld did. Six checks separate a gate that lasts from one that rusts at the joints within a few seasons under the marine layer in Carlsbad, CA, and the breakdown sitting on metal gate contractor carlsbad nap nanny lists them in order. Each one can be tested with a tape and a hand, and each one shows what a metal gate quote actually buys.
Welds and joints
Joints exposed to weather should be fully welded and sealed. Skip welds leave gaps, and gaps hold water and salt against bare steel. Near Agua Hedionda Lagoon and Batiquitos Lagoon the air carries enough salt that a gap rusts from the inside out. Run a finger along each tubing joint and look for pinholes, spatter and unwelded stretches. Thick paint does not fix a rough weld.
Square frame, even gaps
Measure the frame corner to corner both ways. A square gate frame has equal diagonals. Then check the gaps between the gate and its posts. They should be even from top to bottom at both the hinge side and the latch side. A gap that tapers means the frame is out of square or a post has moved.
Hinges and latch
On level ground, a gate with plumb hinges stays where it is left when partly open. A swing gate that drifts open or shut points to hinges out of plumb. The latch should engage without lifting or pushing the gate, which shows it is hanging true. Hinges and latches that bolt on can be replaced later without cutting or rewelding.
Coating coverage
Check the places a sprayer misses. Coating should fully cover inside corners, the underside of rails and the inside of drilled holes. Galvanized steel and a powder coat over clean, prepared metal can both hold up, but the quote should name which one is used. Bare edges inside a picket tube are where rust starts.
Metal, weight and the written description
A heavier gate is not always a better gate. Steel tubing suits a wide driveway swing gate, aluminum does not rust like steel on a lighter opening, and wrought iron is mostly decorative. Weight matters for the operator, since a heavy leaf needs a stronger gate opener and deeper posts. The written description should state the metal, the coating system, the hardware material and how the posts will be set. A line reading only "iron gate" leaves all four open. Two quotes from Carlsbad or Oceanside compare fairly only when those four items match.
