The grinder takes twenty minutes per leaf. Skipping it costs a repaint in two summers. The notes kept at estate gates georgetown new trouble compare finish systems by years to first rust instead of by look, because steel gates in Georgetown, TX face sun, storms and sprinklers every week and a bare weld shows surface rust within a few weeks.

What does the steel need before any coat?

A small dog sits behind a decorative wrought iron gate on a graffiti-covered urban street.

Mill scale and weld spatter come off first, because a finish lasts only as well as the surface under it. Blasting or grinding to bright metal gives paint and powder coat a bite. Weld seams are ground smooth, since sharp edges thin the coating and rust starts there.

Is galvanized better than primer and paint?

Hot dip galvanized steel carries a zinc layer that protects even where it is scratched, and it lasts many years outdoors. It suits tubing frames and posts well. Primer and paint alone rely on an unbroken film, so a chip from a hinge or a lawn tool opens a path for rust under the coat.

What does powder coat add?

Powder coat is baked on and forms a harder, thicker skin than brush paint, and it resists chipping from latches and hinges. Over galvanized or properly cleaned steel it handles Central Texas sun well. Dark colors absorb more heat and fade sooner than light ones, which matters on a south facing entry.

Where does rust start on an estate gate?

Rust starts where water sits: bottom rails, post caps without a seal, weld seams and the inside of open tubing ends. A bottom rail a few inches above the ground stays drier than one touching a concrete apron. Small drain holes at the low points let water out of hollow tubing instead of trapping it.

How do sprinklers change the plan?

Overspray hits a gate daily, and local water carries minerals that leave a crust and speed up coating wear. Heads aimed at the lawn and not the gate protect the finish better than any coat. The lower third of the leaf rusts first wherever spray lands on it.

How are chips touched up?

A chip is cleaned to bare metal, primed with zinc rich primer and sealed with a matching topcoat as soon as it shows. Waiting through a humid stretch lets rust creep under the edge of the coating. Gates near Lake Georgetown and the San Gabriel River get a look every spring for this reason.
