Get an Estimate [(909) 324-5352](tel:+19093245352) Last Updated: October 31, 2026 Open metal fences let Santa Ana wind pass through; rust, not wind, is what ages them. Most fences sold as wrought iron are steel. What lasts is decided by the finish, the welds and how water is kept out of the posts. Wrought iron fence installation in Ontario, CA today almost always means steel. Solid bar steel, hollow tubular steel and aluminum have replaced true wrought iron, and the choice between them, along with the finish and how the posts are set, decides how a metal fence looks in twenty years. [Grove Ontario Fence Builders](https://groveontariofencebuilders.com/) installs ornamental steel and aluminum fences and gates across Ontario and the west Inland Empire, for front yards, pool enclosures, view lines and the tops of block walls. Installation is carried out by licensed and insured fence contractors. This page explains the materials, how they are built and finished, where local rules shape them, and when an old iron fence is worth repairing. A metal fence does a different job from a wood or vinyl privacy fence. It marks a line, keeps children and pets in, satisfies pool barrier rules and leaves the view open. Because air passes through it, a Santa Ana gust that strains a solid 6-foot panel barely loads an open steel fence of the same height. ## What happens on the first visit The first visit measures the line, the gate openings and the slope. Metal sections are fabricated or ordered to length, so measurements decide whether the job uses custom welded sections built to the exact run or prefabricated panels that come in fixed widths. On a slope, the walk also decides between stepped sections, which stay level and drop at each post, and racked panels, whose rails follow the grade. Aluminum panels rack easily; welded steel can be built to the slope. Location on the lot matters more for iron than for most fences, because iron is the usual choice for front yards. Ontario’s Development Code allows 3 feet in a front yard and 6 feet on side, street-side and rear lines, measured from the lowest adjacent finished grade. Property lines, the street right-of-way and the corner clearance at intersections are checked before a post location is set, and the [property line and survey guide](https://groveontariofencebuilders.com/guide/fence-property-line-survey/) explains when a surveyor is needed. After that come the permit, any HOA approval and a DigAlert ticket two working days before digging. The [fence installation process guide](https://groveontariofencebuilders.com/guide/fence-installation-process/) covers the order of work. ## Solid bar steel, tubular steel and aluminum True wrought iron is a fibrous, low-carbon iron worked by hand, and it has not been produced in quantity for decades. It survives in old fences and restoration work. What the trade sells as wrought iron or rod iron is mild steel, built one of two ways. Solid bar steel uses square bar pickets welded to flat or channel rails. It is heavy and stiff, takes a hit without denting, and is the material for custom scrolls, finials and entry gates. Tubular steel uses hollow square tube for pickets, rails and posts. It is lighter and less costly per foot, easy to weld into long runs, and the usual material for view fencing and for toppers on block walls. Its weak point is the inside of the tube: once water gets in through an uncapped post or an open cut, it rusts from within. Aluminum is the third option. It is supplied as powder-coated panels with pickets set through punched rails, weighs a fraction of what steel does and does not rust red. It flexes more than steel, so tall aluminum gates need a well-braced frame and solid posts. Ontario’s code names ornamental iron and tube steel among allowed metal fences, so aluminum is confirmed with Planning for the address before it is ordered. The [wrought iron vs tubular steel vs aluminum guide](https://groveontariofencebuilders.com/guide/wrought-iron-vs-tubular-steel-vs-aluminum/) compares all three in depth, and the table on this page summarizes them. ## Finish, welds and why metal fences rust where they do Steel lasts as long as its coating does. Powder coating, a dry paint baked onto the metal in a factory oven, is thicker and more even than brushed or sprayed paint, and it is the usual finish on new fencing. Some steel fencing is galvanized under the powder coat for a second layer of protection. Field welds and cuts made on site break the factory finish, so they are cleaned, primed and painted before the job is done. Rust starts where water stays longest. On the valley floor that is rarely rain: NOAA’s normals for Ontario’s airport show under 12 inches a year. It is sprinklers that spray the fence daily, soil piled against the bottom rail, and the joint where a post enters its concrete. A crowned footing that sheds water, a post cap on every hollow post and sprinkler heads turned away from the line do more for a steel fence’s life than any paint. Once rust has broken through the finish, it spreads underneath it, so the first bubbles are the time to deal with it. Strong sun ages the finish too. With about 93 days a year at or above 90°F, black and dark bronze finishes run hot and can chalk over time. That is cosmetic until the coating thins enough to let rust start. ## Posts, gates and the ground they sit in Metal fence posts are set in concrete, and their size follows the panel height and the gate loads. A line post on a 4-foot fence carries little; a gate post carries the weight of a swinging steel gate all day, and that load grows with the gate’s width. Gate posts are heavier, set in larger footings, and hung with hinges rated for the gate’s weight, with a stop so the gate does not swing past its latch. That is the part of a metal fence that most often fails first, and the [gate installation](https://groveontariofencebuilders.com/gate-installation/) page covers it in detail. USDA soil survey data puts most of Ontario on loose sand, Tujunga loamy sand in central Ontario and Delhi fine sand in much of Ontario Ranch. Sand gives a post less grip than firmer soil, so footing depth and width come from the post’s job and the soil at that spot rather than one number for every post. In the firmer Hanford coarse sandy loam mapped in Rancho Cucamonga and Upland, the same fence may need a different footing. ## Where iron fits in Ontario and the nearby cities Front yards are where city rules differ most. Ontario caps front-yard fences at 3 feet. Rancho Cucamonga allows open fencing such as wrought iron up to 6 feet in a front yard, while solid fences there stop at 3 feet, so a tall iron front fence that is routine in Rancho Cucamonga is not allowed in Ontario. The [Rancho Cucamonga page](https://groveontariofencebuilders.com/service-areas/rancho-cucamonga/) covers those rules. If an iron fence is used for screening in Rancho Cucamonga, the city requires it to be backed with solid or perforated metal sheeting painted to match. Ontario requires a building permit for open or screened wrought iron fences and gates over 3 feet. Its large-lot AR-2 and RE-2 zones prefer wood rail fencing along equestrian trail easements and say iron should be avoided there. In Ontario Ranch, specific plans such as Edenglen list decorative iron, tubular steel, aluminum or glass for view fencing, and the [Ontario Ranch page](https://groveontariofencebuilders.com/service-areas/ontario-ranch/) explains how those plans work. Gate work in Pomona and the other cities without a page here follows each city’s own rules, confirmed per address. The [Ontario fence permit guide](https://groveontariofencebuilders.com/guide/fence-permits-height-rules-ontario-ca/) has the full height and permit rules. Pools are the other common use. A steel or aluminum pool fence must meet the enclosure rules in California Health and Safety Code 115923: at least 60 inches tall, no gap that passes a 4-inch sphere, no more than 2 inches to the ground, and self-closing, self-latching gates that open away from the pool. The [pool fence installation](https://groveontariofencebuilders.com/pool-fence-installation/) page covers that work. In the foothill fire zones of Chino Hills and north Rancho Cucamonga, metal is the noncombustible choice near a house, which the [wildfire zone fence guide](https://groveontariofencebuilders.com/guide/fences-wildfire-zones/) explains. ## Repairing and repainting an existing iron fence An old iron fence that leans, rattles or shows rust is not automatically a replacement. Surface rust is cleaned back to sound metal, primed and repainted. A broken picket or a cracked weld is cut out and rewelded. A post rusted through at the base can sometimes be cut and sleeved, or replaced on its own, while the sections stay. Those are [fence repair](https://groveontariofencebuilders.com/fence-repair/) jobs, priced by what is broken. Replacement makes more sense when rust has thinned the rails along much of the line, when several posts are rotted through at the concrete, or when the fence no longer meets a rule it now has to meet, such as a pool barrier. The [fence replacement page](https://groveontariofencebuilders.com/fence-replacement/) covers tear-out and a new line. Adding iron to the top of an existing block wall is its own job, on the [block wall extension page](https://groveontariofencebuilders.com/block-wall-fence-extension/). ## What an iron or steel fence costs Ornamental tubular steel, solid bar steel or aluminum fencing typically runs about $35 to $100 per linear foot installed for Southern California projects. Height, picket size and spacing, the post style, the finish, custom scrollwork and on-site welding set where a job lands. A 3-foot aluminum front fence in standard panels sits near the bottom; a 6-foot custom welded solid bar fence on a slope sits near the top. Gates are priced separately by width, frame and hardware, through [gate installation](https://groveontariofencebuilders.com/gate-installation/) or, for wide openings, [RV and driveway gates](https://groveontariofencebuilders.com/rv-gate-installation/) and [automatic gates](https://groveontariofencebuilders.com/automatic-gate-installation/). Removal of an old fence typically adds $3 to $8 per linear foot. These are budgeting figures, not quotes; the [fence cost guide](https://groveontariofencebuilders.com/guide/fence-cost-ontario-ca/) and the [fence cost estimator](https://groveontariofencebuilders.com/tools/fence-cost-estimator/) break them down further. ## What's included - Measuring the line, the gate openings and any grade change the panels must follow - A choice of solid bar steel, tubular steel or aluminum, with picket spacing and top style - Property-line, HOA and permit questions settled before fabrication - Welded sections built to the measured line, or prefabricated panels where they fit - Posts set in concrete footings sized for the height, the gates and the soil - Powder-coated or primed and painted finish, with capped posts - Walk gates with hinges, latches and stops sized for the gate's weight - Stepped or racked sections where the ground slopes - Removal and haul-away of an old fence when it is being replaced (priced separately) ## Solid bar steel, tubular steel or aluminum | | Solid bar steel (sold as wrought iron) | Tubular steel | Aluminum | | --- | --- | --- | --- | | Strength and weight | Heaviest and stiffest; resists bending from impact | Strong for its weight; hollow tube can dent | Lightest; flexes more on tall spans and gates | | Rust | Rusts wherever the finish breaks; needs touch-up | Rusts inside and out once water gets into the tube | Does not rust red; powder coat can chalk with age | | Where it fits | Front-yard fences, entry gates, custom scrolls | Long runs, view fencing, toppers on block walls | Pool fencing and sloped runs where weight matters | | Place in the price | Toward the top of $35 to $100 per foot, more with custom work | Across the range, set by height and picket size | Low to middle of the range for standard panels | ## Related resources Decision Guide Wrought iron, tubular steel or aluminum: which metal fence should you choose?

Yes, in one of two ways. Stepped sections stay level and drop at each post, leaving a triangle of open space under each step. Racked sections tilt their rails to follow the grade so the bottom stays close to the ground, which matters for pets and pool barriers. Aluminum panels rack easily; welded steel is built to the measured slope. ### Why does an iron fence rust first at the bottom of the posts? Water collects there. Sprinkler spray, wet soil and a crack where the post meets its concrete keep the steel damp long after the rest of the fence dries. Hollow posts and rails also trap water inside if they are not capped or drained. Ontario gets under 12 inches of rain a year, so irrigation is usually the bigger source. ### When is a rusted iron fence worth replacing instead of repainting? When rust has eaten through rails or post bases along much of the line, since patching many weak points costs more than new sections. Surface rust is a repaint: the metal is cleaned to sound steel, primed and painted, and broken pickets or welds are cut out and rewelded. A fence that must now meet pool barrier rules may need new sections either way. ### Is an aluminum fence allowed in Ontario? It can be, with a check first. Ontario's Development Code names ornamental steel or iron among the residential fence materials and limits metal fences to ornamental iron or tube steel, chain link and heavy wire mesh. Aluminum is not on that list by name, so an aluminum fence is confirmed with Planning for the address before it is ordered. ### What should I send to price a steel or aluminum fence? The address, the length and height, whether it runs in a front yard, around a pool or along a view, the top style you like and the number of gates. Photos of the line and any slope help, and so does a note on HOA rules. That is enough for a first range; the site walk confirms it. ## Related services ### Gates → Walk gates and side-yard gates, framed and hung so they close square, plus gate repair. ### Block wall extensions → Wrought iron, vinyl and wood toppers that add height to existing block walls. ### Pool fences → Nonclimbable pool enclosures with self-closing, self-latching gates.
