An iron driveway gate is the most visible and most-used part of an iron fence installation. It takes the most load, gets the most operation cycles, and defines the entry to your property. Griffin Fence builds iron gates that match the fence, hang level, and operate correctly for decades — not just on installation day.
The gate is the most mechanically complex component of any iron fence installation. Post sizing, hinge grade, latch type, and frame construction all determine whether the gate stays square and functional over decades of Houston heat, humidity, and daily operation.
Griffin Fence has installed iron fence and gate systems in Houston since 1979. Every gate we build is designed to match the fence panel — same picket pattern, same height, same finish. Gate posts are sized for the gate load, not carried over from line post sizing. Heavy hinges, adjustable gate stops, and quality latches go on every gate regardless of size.
Houston's clay soil requires gate posts set at a minimum of 36 to 42 inches in concrete — deeper for heavy gates. Shallow-set gate posts heave and lean in Houston's wet and dry cycles, causing gates to drag, bind, and eventually fail. We set posts to the depth the soil and gate weight require, not to the minimum that is technically achievable.
Every gate type serves a different application. Here is how the main types compare for Houston properties.
Pedestrian gates 3 to 5 feet wide for side yards, pool areas, and patio entries. Spring closer and self-latching hardware standard for pool barrier applications.
Single-leaf swing gates for openings up to 14 feet. Require swing clearance. Heavier post sizing than line posts — 3 inch pipe standard for residential single swing iron.
Two leaves meeting in the center for driveways 12 to 20 feet wide. Each leaf must have adequate swing clearance. Cane bolt in the ground secures the inactive leaf.
For properties with no swing clearance or sloped driveways. Iron slide gates require heavier post and roller systems than chain link equivalents. Cantilever is preferred for wide commercial openings.
Self-closing self-latching gates designed to Houston pool safety ordinance. Latch on pool side, 48 inch minimum height, no climbable horizontals within the lower 45 inches.
Frame and post spec matched to the planned operator at install time. Swing and slide operators available with keypad, remote, card reader, and intercom access options.
We measure the opening, discuss gate type and automation requirements, confirm post sizing, and provide a written quote with options — good for 30 days.
Finalize the gate design, confirm pool barrier code requirements if applicable, and verify HOA approval needs before fabrication begins.
Gate fabricated and powder coated. Gate posts set in concrete. Gate hung level and plumb, hardware fitted and tested through full operation cycle.
Gate operation test, latch and closer adjustment, and 1-year workmanship warranty on every Griffin Fence iron installation.
Gates are more vulnerable to rust than fence panels because they have more welded joints, more hardware attachments, and more mechanical wear — all of which create opportunities for the powder coat to chip or crack over time. Houston's humidity makes prompt touch-up on any bare metal exposure essential.
Griffin Fence uses a multi-step powder coating process: thorough wire brush cleaning and grinding of all welds, phosphate or zinc primer wash, powder coat in an electrostatic oven environment, and clear top coat on request. This process results in a finish that bonds properly to the steel and resists peeling at weld points, which is where cheap coating processes fail first.
Annual maintenance is straightforward: walk the fence and gate, look for any areas where the coating has chipped or scratched, and apply rust-inhibiting primer and matching paint before rust can start. Most Houston homeowners who have iron fence for decades do this once a year in late fall after hurricane season and find very little to touch up on a quality installation.
If you have existing iron fence or a gate that has developed rust, Griffin Fence provides rust treatment and recoating services. Catching rust early is far less expensive than panel or gate replacement.
