O-Series Standing Seam Awning with Open Ends: The Complete 2026 Buyer's Guide
If you want the architectural punch of a standing seam metal awning at the most accessible price point in the line, the O-Series Standing Seam Awning with Open Ends from 1800Awnings is the model to know. Manufactured in Tampa, Florida and engineered for real Florida conditions — relentless sun, heavy summer rain, and coastal salt air — the O-Series combines Galvalume interlocking roof panels with a fully powder-coated aluminum frame. Its open-end design leaves the sides of the awning exposed, showing off the crisp vertical seams of the panel profile and giving the structure a lighter, more open look than its closed-end sibling. See the O-Series on our product page.
What Is the O-Series Standing Seam Awning?
The O-Series Standing Seam Awning is a premium aluminum awning system built around Galvalume interlocking roof panels and a fully powder-coated aluminum framework. The defining characteristic of the O-Series — compared to the S-Series — is its open ends: the sides of the awning are left open rather than enclosed with finished panels, which exposes the underside of the standing seam roof and the supporting structure for a cleaner, more minimal profile.
Designed and built in Tampa, FL, the O-Series suits windows, doors, patios, storefronts, hospitality entries, and commercial facades. It delivers watertight performance through an integrated flashing system at all roof-to-wall connection points, while the full powder coat — applied to the top and underside of panels as well as all framework and brackets — ensures durability and curb appeal from every angle. Because there are no closed-end panels to fabricate, the O-Series comes in at a lower starting price than the closed-end S-Series. Explore sizing and pricing for the O-Series here.

Why the O-Series Stands Out
Galvalume Panels: The Gold Standard in Metal Roofing
Galvalume is an aluminum-zinc alloy coating applied to high-strength steel — the same material used in commercial metal roofing precisely because it offers superior corrosion resistance compared to standard galvanized steel. On the Florida coast, where salt air, UV, and tropical downpours are everyday realities, Galvalume panels mean your awning won't rust, pit, or degrade the way lesser metal systems do. The interlocking panel profile also creates watertight seams that shed rain cleanly off the face of the structure.
Open-End Design: Clean Lines at a Lower Price
The open-end configuration is the O-Series' signature. By leaving the sides exposed, the design reveals the crisp vertical lines of the standing seam panels and gives the awning a lighter, more contemporary footprint. It's a favorite for modern facades and minimalist storefronts where the metalwork itself is part of the aesthetic. Because there are no enclosed end panels to fabricate and finish, the O-Series is the most budget-friendly way into the standing seam line — starting at $1,785 versus $2,249 for the closed-end S-Series at the same 4 ft size.
Full Powder Coat — Top, Bottom, and Frame
Many awning manufacturers powder coat only the visible exterior surfaces. 1800Awnings coats the top and underside of panels, plus all framework and mounting brackets. This matters in humid environments where moisture creeps into unseen surfaces and causes rust from the inside out. The complete powder coat creates a sealed, corrosion-resistant barrier on every surface that could be exposed to weather — and on an open-end awning, where the underside is fully visible, that finished underside is on display.
Wood Grain Sublimation: Warmth Without Maintenance
Our in-house sublimation process applies a realistic wood grain finish directly to the Galvalume roof panels. You get the natural warmth of timber with zero maintenance — no staining, sealing, warping, or rot. It's ideal for projects that want organic visual appeal with the engineered durability of metal, and it pairs especially well with the O-Series' exposed profile.
Integrated Flashing for Watertight Protection
Built-in flashing at every roof-to-wall connection point prevents water intrusion and ensures a watertight seal. Combined with the interlocking standing seam panels, the O-Series keeps water moving off and away from the structure — critical during Tampa Bay's intense summer storm season.
O-Series vs. S-Series: Which Standing Seam Awning Is Right for You?
Both awnings share the same Galvalume panels, powder-coated aluminum frame, finish options, and watertight construction. The difference is entirely in the ends:
| O-Series (Open Ends) | S-Series (Closed Ends) | |
|---|---|---|
| Side panels | Open — sides exposed | Closed — sides fully enclosed |
| Look | Lighter, minimal, shows the seam profile | Boxed-in, finished, architectural |
| Starting price (4 ft) | $1,785 | $2,249 |
| Best for | Modern facades, budget-conscious projects, where exposed metalwork is desirable | Premium installations where a fully finished, built-in appearance is the goal |
If you love the clean, exposed lines of a standing seam profile and want the best value, choose the O-Series. If you want a fully enclosed, finished-on-all-sides look that reads like a built-in architectural element, step up to the S-Series with closed ends.
Pricing
The O-Series is priced by size. All standard sizes share a 3 ft projection and 3 ft drop:
| Size (Width / Projection / Drop) | Price |
|---|---|
| 4' / 3' / 3' | $1,785 |
| 6' / 3' / 3' | $2,520 |
| 8' / 3' / 3' | $3,255 |

Frequently Asked Questions
What is the O-Series Standing Seam Awning?
The O-Series is a premium aluminum awning system from 1800Awnings featuring Galvalume interlocking standing seam roof panels and a fully powder-coated aluminum frame. Its open-end design leaves the sides of the awning exposed, showing the clean lines of the standing seam profile. It's built in Tampa, FL and starts at $1,785.
What is the difference between the O-Series and the S-Series?
The only structural difference is the ends. The O-Series has open ends, so the sides are left exposed for a lighter, more minimal look. The S-Series has closed ends, fully enclosing the sides for a finished, boxed-in architectural appearance. The O-Series is also less expensive, starting at $1,785 versus $2,249 for the S-Series at the 4 ft size.
How much does the O-Series Standing Seam Awning cost?

Can the O-Series withstand Florida weather?
Yes. The O-Series is engineered for Florida conditions. Galvalume panels resist corrosion from salt air and humidity, the aluminum frame is rust-proof and fully powder coated, and an integrated flashing system at all roof-to-wall connections keeps the installation watertight during heavy rain and storms.
What is Galvalume and why does it matter?
Galvalume is an aluminum-zinc alloy coating bonded to high-strength steel. It offers significantly better corrosion resistance than standard galvanized steel, which is why it's widely used in commercial metal roofing. On an awning, it means long-term durability against rust, UV, and coastal moisture.
Can I get the O-Series in a wood grain finish?
Yes. 1800Awnings offers in-house wood grain sublimation applied directly to the Galvalume roof panels. It delivers the natural look of wood with none of the maintenance — no staining, sealing, or rot — and pairs especially well with the O-Series' exposed underside.
Is the O-Series available as a DIY kit?
Yes. The O-Series can be ordered as a welded, pre-assembled unit or as a knock-down kit shipped flat for easy handling and field installation, making it a practical option for DIY-minded buyers and contractors.
What colors does the O-Series come in?
The O-Series is available in 45+ powder coat colors, including a wide range of RAL colors, anodized silver, matte and gloss black, bronze and copper tones, whites, grays, blues, greens, reds, and more. Wood grain sublimation finishes are also available.
Bottom Line
The O-Series Standing Seam Awning with Open Ends is the smartest entry point into 1800Awnings' standing seam line. You get the same Galvalume panels, rust-proof powder-coated aluminum frame, watertight flashing, and Tampa-built quality as the premium models — at the most accessible price in the family, starting at $1,785. The open-end design isn't a compromise; for modern facades and minimalist storefronts, the exposed standing seam profile is exactly the look many designers want.
If a fully enclosed, finished-on-all-sides appearance is your goal, the closed-end S-Series is worth the step up. But if you want clean architectural lines, proven Florida-grade durability, and the best value in standing seam shade, the O-Series delivers. Configure yours online or call 1-800-AWNINGS (296-4647) to talk through sizing, finishes, and installation with our Tampa team.
