Aluminum Gate Installation in Galveston, TX

Walk gates, pool gates, driveway gates and slide gates in powder-coated aluminum. They can't rust and they are light on hinges and operators. A gate is also where an aluminum fence is most likely to fail, in its hardware, its posts or its warranty. Here is how a good one is built.

The short answer

Aluminum is a strong choice for gates near the Gulf: it can't rust, and its light weight is easy on hinges and gate operators. What separates a good aluminum gate from a poor one is how it is built and hung. In one maker's published spec, fence panels are screwed together but gates are fully welded, each swing gate must carry 300 lb on the latch side, and gates hang on 4″ or 6″ gate posts with thicker walls than the fence posts. Use stainless or aluminum hardware. Read the gate warranty separately: one maker covers swing gates' finish and workmanship for just 1 year. Pool gates must open away from the pool and self-close and self-latch.

How an aluminum gate is built

Welded, not screwed. Aluminum fence panels are usually assembled with screws. Ultra Aluminum's specification even says "welding the pickets to the rails is not permitted" in its fence. Gates are different: "all gates must be fastened and 100% welded at all connections and joints", and each swing gate must "support a 300 lb. vertical load on the latch side of the gate without collapsing". Ask whether the gate in your quote is welded or assembled.

Heavier posts. The same spec uses 2½″ line posts with .075″ walls for the fence, but 4″ or 6″ square gate posts with .125″ walls "on both sides of a gate", set plumb, with the gate hung only after the concrete has hardened. Hinges are a hinge-block and J-bolt design, and double gates get a drop rod.

Strong enough for a driveway? For typical residential openings, yes, when the frame and posts are sized for the leaf. Wide or heavy-use entries go to double leaves or a cantilever slide gate. Aluminum's low weight helps automation, because operators are rated by leaf weight and length. See driveway gates, electric gates and, for a heavier custom look, wrought iron gates.

Elevation of a welded aluminum gate hung between two 4 or 6 inch square gate posts with .125 inch walls. Hinges with blocks and J-bolts on the left are self-closing on walk and pool gates. A self-latching latch on the right is at least 54 inches above the ground for a pool gate, or on the pool side at least 3 inches below the top.

Aluminum pool gates

Most aluminum gates on the island guard a pool. Under the 2021 International Swimming Pool and Spa Code, which the City of Galveston's pool permit requires, a pedestrian pool gate must:

  • open outward, away from the pool;
  • be self-closing and self-latching, and able to take a lock;
  • have its latch at least 54 in. above the ground if it is released from outside, or, on a private pool, on the pool side at least 3 in. below the top of the gate, with no opening larger than ½ in. within 18 in. of the latch;
  • on a double gate, keep one leaf secured and the other self-latching.

The picket spacing rules are the same as for the fence: no opening that passes a 4-inch sphere, and no more than 1¾ in. between pickets if the gate's rails are less than 45 in. apart. See aluminum fences, self-closing, self-latching pool gates and pool fences.

Elevation of a cantilever slide gate: the gate frame spans the opening and continues past it as a braced counterbalance tail carried by two trucks with four wheels and sealed bearings on two truck posts, so nothing rolls on the driveway. A note says that if it is automated, openings from the bottom to 6 feet must stop a 2 and a quarter inch sphere TRUCK POSTS 2 TRUCKS, 4 WHEELS,SEALED BEARINGS LATCH POST OPENING COUNTERBALANCE TAIL AUTOMATED: OPENINGS TO 6 FT MUST STOP A 2¼″ SPHERE NO WHEELS ON THE GROUND IN THE OPENING

A cantilever gate needs clear room beside the opening for the gate and its tail. Standard picket spacing fails the 2¼-inch rule, so automated slide gates get mesh or tighter pickets. The iron gate page covers the rest of ASTM F2200.

Near salt water: hardware and warranty

Hardware is the weak link. The aluminum won't rust, but hinges, latches, screws and brackets can. The Ultra specification calls for all-stainless fasteners. The American Galvanizers Association rates galvanized steel against aluminum as "only a slight chance of a reaction", but recommends an insulating barrier between dissimilar metals, and notes that galvanized steel touching aluminum or stainless near salt water "may require electrical isolation".

Read the gate warranty on its own. Jerith gives homeowners a limited lifetime on its aluminum panels and posts, but swing gates' powder coat and workmanship are covered for 1 year. Ultra excludes "coastal installations" as an extreme condition and requires cleaning every 3 months within 1,500 ft of salt water. Ask for the terms on the exact gate in your quote.

Care. Rinse salt off, keep hinges and latches moving, and check that pool gates still close and latch on their own. See aluminum in hurricane and salt-air areas and wood vs metal gates on the coast.

From estimate to working gate

  1. Free on-site estimate. We measure the opening, swing or slide room and slope, and ask whether the gate guards a pool or may be automated.
  2. Product and a written price. The gate, posts, hinges and latch or operator, and that product's written warranty.
  3. Permits. The pool permit if the gate is part of a pool barrier.
  4. Installation. Gate posts set plumb in concrete, the gate hung once the concrete has cured, and closers, latches or operators adjusted.
  5. Walkthrough. We test the swing, self-closing and latching (or the operator) with you.

What affects cost and timing

We give you a written price after the free on-site visit. The main things that move it:

  • Type and size. Walk and pool gates cost far less than double driveway gates or a cantilever slide gate.
  • Style. Spear tops, finials, arches and puppy-picket spacing.
  • Hardware. Self-closing hinges and self-latching or lockable latches.
  • Posts. Heavier gate posts, or mounting to masonry columns.
  • Automation. An operator, safety sensors, entry controls and power.

Questions we get about this

Will an aluminum gate rust near the coast?
The aluminum won't, because it contains no iron. Steel hinges, latches and screws can, so choose stainless or aluminum hardware, rinse off salt and keep the hardware moving.
Is aluminum strong enough for a driveway gate?
For typical residential openings, yes, when the gate is fully welded and hung on gate posts sized for it. One aluminum spec requires 4″ or 6″ gate posts with .125″ walls and a gate that carries 300 lb on its latch side. Wide or heavy-use entries use double leaves or a cantilever slide gate.
What does an aluminum pool gate need?
Under the 2021 ISPSC, which the City of Galveston's pool permit requires, it must open outward away from the pool, self-close, self-latch and accept a lock, with the latch at least 54 in. high if released from outside. Picket gaps can't pass a 4-inch sphere. See pool gate rules.
Aluminum or iron gate near the beach?
Aluminum, for most homes near the water: it can't rust and it is lighter on hinges and operators. Iron-style steel is heavier and suits custom estate designs, but it depends on its paint. See wrought iron gates.
Can you match an aluminum gate to my existing fence?
Usually, by matching the picket style, spacing, height and color to the fence line. Bring the brand if you know it, since gate parts and warranties are brand-specific.
Can an aluminum gate be automated?
Yes, and its low weight helps. ASTM F2200 then applies: no latch on the automated gate, a separate walk gate for people, and on slide gates, openings to 6 ft that stop a 2¼-inch sphere. See electric gates.
