If you’re planning to build or upgrade a screen enclosure in Orlando or the wider Central Florida region, choosing between aluminum and steel is one of the biggest decisions you’ll face. As a licensed contractor serving the area, we’ve seen firsthand how this choice affects the final project’s durability, style, cost, and daily function. In this article, we’re sharing what we know, what the current research says, and how state and municipal codes shape these options. We want you to make this decision with confidence, knowing what works, what lasts, and what fits your vision and budget.

Materials matter. Especially in Florida’s heat, storms, and humidity.

Let’s look deeper at what sets aluminum and steel apart, focusing on the unique demands of Florida’s climate, local building standards, and what we’ve learned managing hundreds of successful projects through GCM Best Services.

Understanding screen enclosures: purpose and performance

Ask any Florida homeowner with a pool, lanai, or patio: screen enclosures are more than just a home improvement—they shape how families live outside, extending usable space and adding value. Before we outline the material specifics, it’s important to recognize what these structures are designed to do.

• Keep out insects and debris, so you can relax or entertain without constant interruptions.
• Offer shade and lower direct solar exposure, improving comfort even in the heat of summer.
• Add a sense of privacy and safety, especially around pools.
• Reduce leaf, dirt, and bird mess, cutting down on cleaning and chemical use.

The core challenge: Withstand Florida’s sun, storms, wind, and moisture without corroding or failing. How each material faces these stresses will affect both your enjoyment and long-term maintenance costs.

The regional context: Florida’s climate and codes

Central Florida throws some curveballs at outdoor structures. Our sandy soils, hurricane threats, high humidity, and blazing UV make it hard for just any product to last.

Builders and contractors like us at GCM Best Services also work under strict oversight. The Florida Administrative Code R. 61G4-15.100, for example, lays out who can construct or alter aluminum and screen enclosures, what kind of structural changes require additional permitting, and where masonry or wood can be included as explained in this regulatory summary.

Local municipalities, such as the City of Tampa, further define enclosures’ placement and construction standards. Their construction guidance highlights that most residential screen enclosures use lightweight framing materials such as aluminum, making their widespread use clear in the region’s construction norms according to this official overview.

The basics: How aluminum and steel compare

• Aluminum: Used widely for pool cages and lanais. Known for its resistance to rust, lightweight nature, and ease of fabrication, aluminum comes in several grades and finishes. Most enclosures in Central Florida use aluminum extrusions or roll-formed tubes.
• Steel: Typically used for high-load applications, commercial structures, or places where ultra-high strength is needed. Galvanized, powder coated, or stainless steel options can be found, each with unique corrosion resistance and maintenance requirements.

Now, let’s break it down further—strength, longevity, cost, looks, and maintenance.

Strength and wind resistance in Florida storms

Florida’s building codes require enclosures to withstand significant wind events. This isn’t just about surviving hurricane season, but also everyday gusts and summer storms.

• Aluminum: When designed to code, modern aluminum enclosures use engineered extrusions, reinforced corners, and hurricane anchor systems that deliver robust performance. Frames are often spaced at intervals to balance strength and sightlines. Properly assembled and anchored, aluminum can withstand wind loads prescribed by Florida building code, especially when using high-grade fasteners and brackets.
• Steel: Steel’s tensile and yield strength is much higher than aluminum, so it can offer thinner or longer unsupported spans. If a project requires large open vistas with minimal posts or an industrial-scale build, steel might be considered. Still, in most residential applications, the difference in practical wind load resistance is marginal once code-compliant design is applied.

We’ve found that clever design and installation have a far bigger impact than switching materials. Fastener quality, connection details, and site-specific engineering account for most of the real-world performance differences we see in Central Florida.

Corrosion and longevity in humid, salty air

Florida’s humidity, salt-laden air, and frequent storms put every outdoor material to the test. Rust, oxidation, pitting, and paint fading are real concerns for anyone investing in a screen enclosure. Here’s how each material stands up:

• Aluminum: Aluminum forms an oxide layer naturally. This acts as a built-in shield against corrosion, even when cut or scratched. Most products made for the Florida market come powder coated in white, bronze, or custom colors, adding another layer of defense. While aluminum can oxidize, this process is typically cosmetic and doesn’t eat away at the structural metal in the same way as rust does with steel.
• Steel: Unless it’s stainless or heavily galvanized and coated, steel will rust aggressively in Florida conditions. Even top-quality paint can chip, letting moisture and salt do their work. Galvanized or powder coated steel offers better durability, but spots where the coating gets interrupted—at fasteners, joints, or cut ends—are usual points of early failure. In our experience, regular inspections and touch-ups are needed to prevent corrosion from spreading in these areas.

A study by the Florida Solar Energy Center looked at how different enclosure materials affect light, heat, and radiation transmission. Their data confirms that, for aluminum, pigment and finish have a much greater impact on longevity than the alloy itself, underlining the value of high-quality coatings and good installation practices.

Weight, flexibility, and installation differences

Working in the field, we’ve come to appreciate how material weight and flexibility change the entire installation process—and even project options for our clients.

• Aluminum: Lightness is one of aluminum’s best features. It means less stress on foundations and footers, the ability to prefab parts off-site, and faster installation times. Aluminum frames can often be modified or repaired in place without removing screen panels or supports.
• Steel: With higher density and weight, steel parts require heavier lifting equipment, more robust footings, and careful placement during installation. Even for small enclosures, transporting and assembling steel systems takes longer and may block access to surrounding areas during work. Adjustments or repairs can be labor-intensive.

Light frames make a difference—on your budget and your site.

For homeowners who need to blend the enclosure with existing landscaping, pavers, or artificial turf, the reduced weight and faster install of aluminum is a clear advantage.

Thermal expansion, color, and finish options

Florida’s sun gets hot. This isn’t just a comfort issue, it affects your enclosure’s structure.

• Aluminum: Aluminum expands and contracts slightly more with temperature swings than steel, but these movements are small at the scales used in screen enclosures. Key design features—such as slip joints, flexible fasteners, and expansion trims—manage this without trouble. Powder coating makes possible a wide range of colors and finishes, from bright whites to deep bronzes.
• Steel: Available in fewer “standard” finishes, especially for outdoor use in Florida. Steel’s lower rate of expansion can be helpful on large, flat roofs or support spans, but this is less relevant in most pool cages or lanais.

We often recommend, after reviewing a property’s sun exposure and existing trim, a coated aluminum tailored to match your home’s palette and the region’s requirements. Reflective, lighter colors remain cooler to the touch and show fewer signs of UV aging over time.

Cost differences: upfront and over time

Money counts—not just today, but years down the line. We believe it’s essential to look beyond the price tag at installation and consider what each material will cost in upkeep, repair, and value.

• Aluminum: Lower material and transport costs locally, easier handling, and less prep work. With modern extrusion, it’s possible to create long-lasting frames with minimal waste. Powder coating, while it does add to initial costs, pays for itself in reduced painting and touch-up over the years.
• Steel: Higher upfront costs due to both material and labor. If galvanized or powder coated finishes are needed (which we recommend for Florida), add further expense. Repairs and corrosion management add to the lifetime expense. Steel does offer high perceived value for large, architecturally ambitious projects, but for most residential enclosures, the return on investment favors aluminum.

As a company that works on every step from permitting to final walk-through, we weigh not only the immediate out-the-door price but the lived cost of ownership. When factoring in maintenance, paint, and possible repairs, aluminum remains an affordable, low-headache pathway for the vast majority of homes we service.

Safety, code requirements, and using the right contractor

Screen enclosures in Florida don’t just enhance lifestyle—they must comply with state and municipal requirements. A contractor’s ability to pull the right permits, assure code compliance, and pass inspection is just as important as the brand or grade of metal used.

As outlined under Florida Administrative Code, specialty aluminum or screen enclosure contractors are licensed for the fabrication, erection, and repair of such structures, including any “incidental” foundation or masonry work, but not for changes to supporting structural elements of your house itself. Working with a licensed, insured provider means your project is built to code, and you’re protected if something unexpected happens.

A warranty is only as good as the people behind it.

Every enclosure by GCM Best Services is delivered with a clear written warranty, maintenance guide, and a photo record of our work—so nothing’s left to chance.

Appearance and property value

We know that an enclosure is as much about looks as it is about engineering. Most homeowners want something that feels inviting and complements their home, not an eyesore or afterthought.

• Aluminum: Modern manufacturing guarantees crisp lines, slim profiles, and good paint retention. You can choose from textured or glossy powder coats, match trims or go for contrast, and integrate the frame design with lighting, fans, or screens. Aluminum tends to blend with both new homes and retrofits.
• Steel: Known for its ability to carry architectural detailing—the industrial look, ornate scrollwork, or very large beams with minimal flex. However, painting touch-ups and surface rust are common cosmetic issues, and some homeowners find the overall aesthetic heavier or less compatible with Florida’s mid-century and Mediterranean house styles.

Solar performance, shade, and comfort

In Florida, how your enclosure frames and screens interact with sunlight impacts daily comfort. The Florida Solar Energy Center offers details on how different screens and framing cast shade, transmit solar heat, and affect daylighting. Aluminum’s slim profile means less visual obstruction, more sky view, and lighter overall feel under the enclosure. Steel beams—while sometimes thinner—tend to be chunkier in practice for rust protection.

Choosing the right configuration, mesh pattern, and finish can help manage both direct sun and glare, letting you use your patio even during the hottest months.

Maintenance and repair: what you’ll really face each year

No one wants a project that creates endless maintenance. Our customers often ask: “What will I have to do in five years to keep this looking good?” The answer is different for each material:

• Aluminum: Occasional washing with plain water keeps it looking fresh. A gentle non-abrasive cleaner is enough for tougher grime or mildew. Inspections every year or two for loose fasteners or minor scratches are recommended, but corrosion rarely spreads if the powder coat stays intact. Screens can be patched or replaced as needed without touching the frame.
• Steel: Needs more frequent attention. Look for paint chips, rust spots, and flaking coatings, especially after storms. Small areas can be sanded and touched up, but deep rust may require replacing entire sections. Fastener areas and corners need special checking. Well-maintained steel can last, but it’s a labor of vigilance.

At GCM Best Services, we walk our clients through a maintenance guide and provide details on the coatings used, so you know exactly which cleaning products and methods to use. That’s peace of mind that pays off as seasons pass.

Who should consider steel over aluminum?

Although aluminum is the dominant material by volume in Florida enclosures, steel isn’t completely out of the picture. From our experience, steel makes sense only in specialized cases, such as:

• Commercial, multi-story, or very large-span enclosures where additional support is needed.
• Restoration of historic properties where steel was used in the original design.
• Modern or industrial-style homes seeking unique architectural elements hard to produce in aluminum.

For the rest—pool cages, screen rooms, patios, and lanais for Florida’s single-family homes—aluminum checks every box for code compliance, longevity, aesthetics, and value.

Frequently asked questions

What is better for Florida enclosures?

For nearly all Florida residential enclosures, aluminum is the preferred material due to its natural resistance to corrosion, compliance with local codes, and lightweight installation advantages. Steel sees limited use in large commercial or specialty projects but is not recommended for most home applications because of maintenance and corrosion risks.

How much do aluminum enclosures cost?

Costs for aluminum screen enclosures can vary based on size, design, finish, and site conditions. In Central Florida, typical installations range from several thousand dollars for small lanais to much more for large pool cages, especially if custom features or color-matched powder coating is added. We recommend scheduling a free on-site assessment to receive a detailed, fixed-price estimate.

Is steel or aluminum more durable?

In Florida’s humid, salty environment, aluminum is more durable for screen enclosures. Its built-in oxide layer and powder coating shield the frame from damage, while steel requires constant vigilance against rust and paint breakdown. When both are kept well maintained, steel can last, but aluminum needs far less attention in practice.

How can I maintain my enclosure?

Maintain an aluminum enclosure by rinsing with plain water a few times a year, using gentle cleaners on stubborn areas, and checking fasteners annually. For steel, regular inspections for rust, quick paint touch-ups, and repair of scratches are needed. Always follow your installer’s guide to avoid damaging finishes or hardware.
