Custom Gate Design in Galveston, TX
A custom gate is drawn for one opening instead of picked from stock panels. You choose the leaf split, the top, the infill, the frame and finish, and the hardware, and each choice has to work with the posts, the salt air and the local rules. Try it in the designer below.

Custom gate design comes down to five decisions. The first is the size and leaf split, which sets the gate post: one steel line’s table goes from 2.5 in. for a leaf up to 4 ft to 6 in. for 10–16 ft. The others are the frame and finish, the infill and top, the hardware and automation, and the local rules. For salt air, ask whether steel is hot-dip galvanized after fabrication (ASTM A123) or built from pre-galvanized tube (G90 is about 0.76 mil of zinc per side). In a pool barrier, no opening may pass a 4 in. sphere, and gaps drop to 1¾ in. when rails are under 45 in. apart.

What “custom” means for a gate
A stock gate comes in set widths and styles. A custom gate is sized to your opening and designed around how you’ll use it: the width of each leaf, the height at the posts, the top, the infill, and the hardware. It can match an existing fence or gate, or mix materials such as wood boards in a steel frame. See what custom fabrication actually means and matching an existing fence.

Design your gate
Set the opening, the leaves, the top and the infill. The drawing redraws as you go, and the checks show the gate post one maker lists for that leaf, how open the design is, and which Galveston rules apply.
Gate post: Ameristar Montage Commercial catalog Table 1 (up to 4 ft leaf 2.5 in., 4–6 ft 3 in., 6–10 ft 4 in., 10–16 ft 6 in.), one product line’s table and an example only; masonry columns are designed separately. Picket count and openness are arithmetic: 1 in. pickets, 2 in. stiles, pickets only. Front yard: City of Galveston LDR §2.501. Pool: 2021 ISPSC §305.2 and §305.3 (required by the City’s pool permit).

Frame and infill options
| Option | Why people choose it | What to ask about |
|---|---|---|
| Steel pickets | Strong, classic look; spear, flat or arched tops | Hot-dip galvanized after fabrication (A123) or pre-galvanized tube, then powder coat. ASTM F2408 covers galvanized ornamental steel. |
| Aluminum pickets | Light and doesn’t rust | Leaf width and bracing; insulate where it touches other metals |
| Wood boards in a steel frame | The warmth of wood without a wood frame to sag | Board species and spacing; how the boards are fastened to the frame |
| Horizontal slats | Modern look, more privacy | Whether it counts as solid for front-yard height; climbability at a pool |
| Laser-cut panels | A pattern or motif, privacy with some light | Panel thickness, the open area, and cutout width at a pool |

How a custom gate comes together
- Free on-site estimate. We measure the opening, check the posts or columns, the ground and the room to swing or slide, and talk through how you’ll use the gate.
- Design choices. Leaf split, height, top, infill, frame and finish, hardware, and whether it will be automated now or later.
- Rules check. Front-yard height, historic district, pool barrier and automation standards, before anything is built.
- Written price, then fabrication and installation. Ask for the dimensions and the finish in writing.
What affects cost and timing
We give you a written price after a free on-site estimate. What moves it:
- Size. Wider and taller leaves need more material and heavier posts.
- Frame and finish. Steel or aluminum, and galvanizing and powder coat for salt air.
- Infill and top. Arches, laser-cut panels and wood infill take more fabrication than flat pickets.
- Hardware and automation. Heavy hinges, locks, drop rods, an operator and access control.
- Posts and columns. New posts, or fitting to existing masonry.
