O-Series Standing Seam Awning with Open Ends: The Complete 2026 Buyer's Guide
If you want the architectural look of a standing seam awning at the most accessible price in our line, the O-Series Standing Seam Awning with Open Ends from 1800Awnings is the model to know. It's made in our Tampa, Florida shop for real Florida weather: intense sun, heavy rain and coastal humidity. It pairs Galvalume interlocking roof panels with a fully welded aluminum frame, powder coated on the top and underside. The open ends give it a lighter profile and let heat and moisture escape from underneath. See the O-Series on our product page.
What Is the O-Series Standing Seam Awning?
The O-Series is one of our two standing seam awnings. Both share the same Galvalume panels, welded aluminum frame and full powder coat. The O-Series is defined by its open ends: the sides are left open for a visually lighter profile that shows off the standing seam lines.
Open sides let trapped heat and moisture escape from underneath, a real advantage on wide window spans and in humid Gulf Coast and Southeast climates. Because there are no end panels to fabricate, it's also the most affordable way into our standing seam line. It suits windows, doors, patios, storefronts, hospitality entries and commercial facades.

Why the O-Series Stands Out
A welded aluminum frame for strength
Big-box awnings ship as modular parts that bolt together, and every bolted joint is a place that can work loose, rack out of square, or trap water. Our frames are cut from aluminum extrusions and welded by our own fabricators in Tampa, fusing the pieces into one rigid frame. It stays square, spreads wind and rain loads across the whole structure instead of a string of connections, and has no bolt holes at the joints where corrosion starts. And aluminum won't rust.
Powder coated top and underside
Powder coating is electrostatically applied and baked on, forming a thicker, tougher layer than paint that resists chipping, fading and UV. Many awnings only get finish where you see it from the street. We coat the top and the underside of every Galvalume panel, plus the whole frame and every bracket. The underside sits in shaded, humid air where condensation and salt collect, so it's where corrosion usually begins, and it's the side you look up at from your porch or entry.
Galvalume panels
Galvalume is steel with an aluminum-zinc coating, widely used in commercial metal roofing for its corrosion resistance. The interlocking standing seam profile channels water off the front edge, and the powder coat goes over an already corrosion-resistant base.
Open ends
Open sides keep the awning visually light and let heat and humidity vent out from underneath instead of building up. Because the underside is on display, our top-and-underside powder coat matters even more here.
Wood grain without the upkeep
Our in-house sublimation process bonds a realistic wood grain to the panels: the warmth of cedar or walnut with no staining, sealing or rot. It's popular for craftsman homes, upscale storefronts and restaurant patios.
Welded or knock-down
Order the O-Series pre-welded for the strongest one-piece install, or as a knock-down kit made from the same aluminum and finish for easier shipping and handling.
O-Series vs. S-Series: Open Ends vs. Closed Ends
| S-Series (closed ends) | O-Series (open ends) | |
|---|---|---|
| Sides | Enclosed with finished panels | Open |
| Look | Boxed-in, built-in, architectural | Lighter, shows the seam profile |
| Performance edge | Blocks low-angle side sun and wind-driven rain | Lets heat and moisture escape from underneath |
| Best for | West-facing windows, exposed entries, finished facades | Wide windows, humid Gulf Coast and Southeast climates, modern facades |
| Starting price (44") | $1,558 | $1,375 |
Both share the same Galvalume panels, welded aluminum frame and top-and-underside powder coat. Choose the O-Series for airflow, a lighter profile and the best value; step up to the S-Series for west-facing windows and maximum side protection.

Who Is the O-Series Best For?
- Florida and Gulf Coast homeowners who need an awning that handles UV, humidity, salt air and storms without rusting.
- Humid and coastal properties where venting heat and moisture from under the awning helps.
- Budget-conscious buyers who want a genuine welded standing seam awning at the lowest entry price in the line.
- Storefronts and retail tenants who want an awning that looks custom-designed rather than off-the-shelf.
- Hospitality and restaurant operators covering entries and patios where appearance matters.
- Modern facades where exposed, minimal metalwork is part of the look.
- Anyone replacing a failed fabric or light metal awning with a permanent, welded upgrade.
How to Order Your O-Series Awning
- Measure your opening. Measure the width including trim and add a few inches each side. Decide how far out (projection) you need for shade and rain cover.
- Pick a standard size or request a custom one. Standard widths run 44" to 104" with 24" or 36" projection. Anything else is built to order.
- Choose your finish. Pick a powder coat color or add wood grain sublimation, and choose flat or pitched.
- Choose welded or knock-down. Welded for the strongest one-piece install; knock-down for easier handling.
- Order or get a quote. Order on the O-Series product page, or call 1-800-AWNINGS (296-4647) for a custom quote and CAD drawing before you buy.
Frequently Asked Questions
What is the O-Series Standing Seam Awning?
A standing seam awning from 1800Awnings with Galvalume interlocking roof panels on a fully welded aluminum frame, powder coated on the top and underside. The open ends give a lighter look and let heat and moisture escape. It's built in Tampa, Florida.
How much does the O-Series cost?
Standard sizes run from $1,375 at 44" wide to $3,250 at 104" wide, all with a 24" drop and your choice of 24" or 36" projection at the same price. Custom sizes are quoted. Shipping is quoted by destination.
What is the difference between the O-Series and the S-Series?
The ends. The O-Series has open ends that let heat and moisture escape, a plus in humid climates, and starts at $1,375. The S-Series has closed ends that block side sun and wind-driven rain, making it best for west-facing windows, and starts at $1,558.
Is a welded aluminum frame stronger than a bolt-together kit?
Yes. Welding fuses the frame into one rigid piece with no bolted joints to loosen, rack out of square or trap water, and aluminum won't rust.
Why powder coat the underside?
The underside sits in shade and humidity and collects condensation and salt, so it's where corrosion usually starts. It's also the side you see from below. We coat the top and underside of every panel, plus the full frame and brackets.
Can I get a custom size?
Yes. Every O-Series is built to order, so we can make widths, projections and drops outside the standard sizes. Call 1-800-AWNINGS (296-4647) or request a quote.
Can I get a wood grain finish?
Yes. Our in-house sublimation applies a realistic wood grain directly to the Galvalume panels with no maintenance.
How long does it take to get one?
Most orders ship 2–3 weeks after the order is confirmed.
What warranty comes with it?
5 years on powder-coated finishes and 2 years on workmanship. Damage from severe weather, accidents or improper installation isn't covered.
The Bottom Line
The O-Series is the smartest entry point into our standing seam line. You get the same welded aluminum frame, top-and-underside powder coat and Galvalume panels as the S-Series, with open ends that vent heat and humidity and a lower price. If you need maximum side protection for a west-facing window, compare the S-Series.
Configure your O-Series or call 1-800-AWNINGS (296-4647). Our team in Tampa will help you pick the right size and send a CAD drawing before you buy.
