Steel, Aluminum or Wrought Iron for a Georgetown Gate

By metal gates georgetown files

Choosing between steel, aluminum and wrought iron for a Georgetown gate is a decision about weight, upkeep and how the gate will age in the Texas sun. All three metals make handsome, secure gates, but they behave very differently once they are hung on a post and left outdoors for fifteen summers. Knowing those differences before ordering saves a homeowner from a gate that sags, rusts or simply does not suit the property.

What each metal really is

Steel is iron with a small amount of carbon, and it is the workhorse of the gate trade. Most gates described as iron in a showroom conversation are actually mild steel tube or bar, because it is easy to cut, bend and weld. Aluminum is a different material altogether: a light, soft metal that does not rust the way steel does and that is usually formed from extruded shapes. Wrought iron in the strict historical sense is a fibrous, hand forged metal that is rarely made today. Genuine antique wrought iron turns up on older estates and in salvage yards, and new work that carries the name is nearly always steel finished to look traditional.

That naming confusion matters when comparing quotes. A buyer who wants real wrought iron should ask what the gate is made from, and a fabricator who answers mild steel is giving an honest and normal answer. The look can be identical. The difference lies in the material grade and in how it is protected.

Steel, strong and forgiving to build with

Steel offers the best strength for the least bulk. A frame of steel tube can span a wide driveway opening without a visible brace, and the metal can be bent into scrolls, rolled into arches and welded into nearly any pattern. Repairs are simple because a welder can cut out a damaged section and join in a new one. For long spans, heavy ornamental panels or a gate that has to stop a determined person, steel is the usual answer.

The trade off is that bare steel rusts. Rust needs oxygen and moisture, and Georgetown supplies both in the form of morning dew, sprinkler overspray and the sudden downpours that follow a dry spell. A steel gate depends on its coating, whether zinc, powder coat, paint or a combination, and it needs that coating to stay unbroken. When a scratch exposes bare metal, rust can start underneath the finish and lift it. Steel gates reward a yearly look for chips and a quick touch up.

Steel also carries weight. A large driveway leaf in steel can be heavy enough to demand strong posts, deep footings and robust hinges. That weight is a virtue for security and a burden for hardware, so the post and hinge choices must match the metal.

Aluminum, light and free of red rust

Aluminum forms a thin oxide skin that stops further corrosion, so it does not produce the orange stains that steel does. It weighs roughly a third as much as steel for the same volume, which makes it easy on hinges, openers and posts. Aluminum gates are a popular pick for pool enclosures, side yards and homes where a motor will move the gate all day.

The limits are strength and stiffness. Aluminum is softer, so it dents more easily and flexes more under load. To reach the same stiffness as steel a fabricator uses thicker walls or larger sections, and very wide spans may need extra bracing. Welding aluminum requires different equipment and skill, and the heat from a weld can soften the metal beside the joint. Good shops allow for this in their design. Aluminum also costs more per pound than steel, though the lighter hardware can narrow the gap.

Because aluminum is so often an extruded product, its decorative range is narrower. Catalog pickets and rails come in set profiles, and fully custom scrollwork is harder than it is in steel. For a clean, simple picket gate this is not a problem. For an ornate entry it can be.

Wrought iron, the real thing and the look

True wrought iron has a grain like wood and resists corrosion better than modern mild steel, which is why century old iron fences still stand. Genuine material is scarce, and a gate made from reclaimed wrought iron is a specialty piece. Most people who say they want wrought iron are describing a style: slender vertical bars, forged looking collars, hand worked scrolls and a dark finish. That style can be built in steel and, in lighter versions, in aluminum.

If an antique gate or reclaimed panel is part of the plan, a fabricator can often restore it, repair cracked joints and mount it on new posts. Old iron may need careful handling because it can be brittle in places and hard to weld without the right technique.

Matching metal to a Georgetown property

Georgetown properties vary a great deal. A home near the courthouse square and Old Town may want a traditional dark gate that suits older architecture, and steel with scrollwork is a natural fit. A newer subdivision lot with a standard fence line might do better with a clean aluminum or steel picket gate. Lots near the San Gabriel River or Lake Georgetown see more humidity and sometimes flooding, which makes a protected coating more important on steel and favors aluminum for areas that stay damp.

Sun is the other constant. Long summers with intense light fade cheap paint and make dark metal hot to the touch. A gate near a play area or a pool deck should have a lighter finish or sit in shade, and the metal choice affects how hot the surface gets. Aluminum and steel both warm quickly, but color changes the result more than the metal does.

Soil matters for the posts that carry the gate. Clay that swells and shrinks, and limestone near the surface, both affect how deeply and how firmly a post can be set. Heavy steel gates ask more of that foundation than light aluminum ones.

Questions to put to a fabricator

• What exact metal is the gate frame made from, and how thick are the walls?
• How is the metal protected from rust, and what is done to cut ends and welds?
• How much will the finished gate weigh, and are the hinges and posts sized for that weight?
• What happens to the finish where hardware is attached?
• Can the work be repaired later without replacing the whole gate?

Honest answers to these questions reveal more than a sample photo. A fabricator who explains the choices in plain terms and admits the limits of each metal is usually a good sign.

Upkeep over the years

Steel asks for attention to the finish, with a wash twice a year and quick repair of any chip. Aluminum asks mostly for cleaning, and a hose and mild soap handle most grime. Neither metal likes to sit under a leaking sprinkler head, since constant wetting wears coatings down and leaves mineral stains. Pointing sprinklers away from the gate is one of the cheapest steps an owner can take.

Hinges and latches are the moving parts, and they wear faster than the metal itself. Whatever the frame is made from, plan on a little oil or dry lubricant on moving parts each season.

Making the choice

For maximum strength, wide spans and ornate design, steel with a good coating is hard to beat. For light weight, easy automation and freedom from red rust, aluminum is a sound pick. For a period piece, reclaimed wrought iron is special but needs expert handling. Most Georgetown homeowners end up with one of the first two, and the better question is usually not which metal but how well the gate is built and finished. The following pages in this guide look at that side of the question, from wall thickness and welds to galvanizing and powder coat, so a buyer can judge a gate by what it is made of rather than by its photograph alone.
