Hercules Aluminum Torsion Bar Upgrade: Corrosion-Resistant Strength for Large-Span Retractable Awnings (2026 Guide)

What Is the Hercules Aluminum Torsion Bar Upgrade?

The Hercules Aluminum Torsion Bar Upgrade is a factory upgrade for the Hercules Shademaker Retractable Awning that replaces the standard torsion bar with an all-aluminum torsion bar. The torsion bar is the structural backbone of a retractable awning — the horizontal support bar that carries the folding arms and absorbs the constant spring tension that keeps the fabric taut. On a system as large as the Hercules, which spans widths from 15 to 40 feet with projections up to 16′ 6″, the torsion bar works harder than on any other retractable awning in the 1800Awnings lineup.

Upgrading to aluminum matters most in one place: the coast. Aluminum does not rust the way steel components can, which makes this upgrade especially popular for Tampa Bay waterfront homes, beachfront restaurants, and any Florida installation exposed to salt air and daily humidity. It also reduces the weight the wall bracket system has to carry. The upgrade is ordered by awning width, in one-foot increments from 17′ to 40′, priced from $536 to $1,259 at 1800Awnings.com.

Key Specifications

Why the Aluminum Torsion Bar Upgrade Stands Out

Corrosion Resistance Where It Counts

The torsion bar sits inside the awning assembly where moisture collects and salt spray settles — and where you can't easily inspect it. Aluminum forms a natural protective oxide layer instead of rusting, so the structural heart of your awning stays sound year after year. For homes on Tampa Bay, Clearwater Beach, St. Petersburg, and anywhere else within a few miles of salt water, this is the single most cost-effective longevity upgrade you can make to a Hercules system.

Built for the Largest Spans in the Lineup

The Hercules is the heavy-duty flagship of the Shademaker series — it covers widths up to 40 feet and projections up to 16′ 6″, dimensions most retractable awnings simply can't reach. The wider the awning, the longer the torsion bar and the more load it manages. The aluminum upgrade is sized to every Hercules width from 17′ to 40′, so protection scales with the span.

Less Weight on Your Wall

Aluminum is significantly lighter than steel for the same length of bar. On a 30- or 40-foot awning, that weight reduction eases the constant static load on wall brackets and fasteners — a meaningful benefit on large installations where every component is already working at commercial scale.

A One-Time Upgrade, Not a Maintenance Item

Unlike coatings or touch-up treatments that need reapplication, an aluminum torsion bar is corrosion-resistant through and through. You order it once, at the time of purchase, and it protects the awning for its entire service life — complementing the 10-year Sunbrella® fabric warranty and 5-year Somfy® motor warranty that come with every Hercules.

Aluminum vs. Standard Torsion Bar: Which Should You Choose?

The standard Hercules torsion bar is a proven, heavy-duty component and remains the right choice for many inland installations. The aluminum upgrade earns its price in specific conditions:

• Choose the standard bar if your awning is installed well inland, in a dry climate, or under a protective hood in a low-humidity region, and you want the lowest system price.
• Choose the aluminum upgrade if you're within a few miles of the coast, in a high-humidity climate like Florida's, installing at maximum widths (30′–40′), or you simply want the longest possible structural service life with zero corrosion worry.

Many Tampa Bay buyers pair the aluminum torsion bar with the Hercules Hood & Hood End Covers for a fully weather-hardened system: the hood shields the roller and fabric from above, while the aluminum bar eliminates corrosion inside the assembly.

Hercules Aluminum Torsion Bar Upgrade Pricing (2026)

Pricing is by awning width. Current prices at 1800Awnings.com:

As a rule of thumb, each additional foot of width adds roughly $30–$33 to the upgrade price.

Who Is This Best For?

• Coastal Florida homeowners — anyone on or near Tampa Bay, the Gulf beaches, or the Atlantic coast where salt air attacks steel components.
• Restaurants and hospitality venues — commercial Hercules installations that need maximum uptime and minimum maintenance over wide dining patios.
• Buyers ordering maximum widths — 30′–40′ systems where the torsion bar carries the greatest load and weight savings matter most.
• High-humidity inland installations — screened-lanai-adjacent or poolside settings where moisture exposure is constant even away from the coast.
• Long-horizon owners — anyone who plans to keep their awning 15+ years and wants the structure to outlast the fabric.

How to Order

1. Configure your Hercules Shademaker Retractable Awning — choose your width (15′–40′), projection (14′ 9″ or 16′ 6″), frame finish, and Sunbrella® fabric.
2. Visit the Aluminum Torsion Bar Upgrade page and select the size that matches your awning width (17′–40′).
3. Add both to your cart, or call 1-800-AWNINGS (296-4647) and our Tampa team will configure the complete system for you.
4. Your Hercules ships with the aluminum torsion bar integrated — no field retrofit required when ordered together.

Frequently Asked Questions

What is a torsion bar on a retractable awning?
The torsion bar is the main horizontal structural bar of a retractable awning. It mounts to the wall brackets, carries the folding lateral arms, and absorbs the spring tension that keeps the fabric tight. It is the load-bearing backbone of the entire system.

What does the Hercules Aluminum Torsion Bar Upgrade do?
It replaces the standard torsion bar on the Hercules Shademaker with an all-aluminum bar. Aluminum resists corrosion naturally, so the awning's core structure is protected in salt-air and high-humidity environments, and the overall assembly weighs less on the mounting brackets.

How much does the aluminum torsion bar upgrade cost?
Pricing depends on your awning width: $536 for a 17′ system up to $1,259 for a 40′ system, in one-foot increments. That's roughly 5–7% of the cost of a typical Hercules awning — a small premium for permanent corrosion protection.

Can I add the aluminum torsion bar to an existing Hercules awning?
The upgrade is designed to be ordered with a new Hercules system so the bar is integrated at the factory. If you already own a Hercules and are interested in a retrofit, call 1-800-AWNINGS (296-4647) to discuss options for your installation.

Do I need this upgrade if I don't live near the ocean?
Not necessarily. Inland installations in dry climates do well with the standard bar. But in Florida's humidity — even inland Tampa, Orlando, or Brandon — moisture exposure is constant year-round, so many inland Florida buyers choose the upgrade for peace of mind and longer service life.

How does aluminum compare to steel for corrosion?
Steel oxidizes into rust, which flakes away and progressively weakens the metal. Aluminum oxidizes into a thin, hard, self-sealing oxide layer that protects the metal underneath. That's why aluminum is the standard material for marine and coastal architectural hardware.

What sizes does the upgrade come in?
Twenty-four sizes, matching Hercules widths from 17 feet to 40 feet in one-foot increments. You simply order the size that matches the width of your awning.

Does the upgrade affect the awning's warranties?
No. Your Hercules still carries its 10-year Sunbrella® fabric warranty and 5-year Somfy® motor warranty. The aluminum torsion bar is a factory-supported structural upgrade, not a third-party modification.

Bottom Line

The Hercules Aluminum Torsion Bar Upgrade is inexpensive insurance for the most structural component of the largest retractable awning 1800Awnings sells. For $536–$1,259 — a fraction of the system price — you replace the one part that quietly bears every pound of tension in the awning with a bar that cannot rust. In coastal and humid Florida environments, that trade is easy to justify.

If you're configuring a Hercules for a waterfront home, a beachfront restaurant, or any wide-span application you expect to keep for decades, add the aluminum torsion bar at the time of order. It integrates at the factory, it never needs maintenance, and it ensures the structure outlasts everything mounted to it.
