Why Aluminum for Support Brackets?

Most hardware stores sell steel support brackets. They are cheap, heavy, and prone to rust. An aluminum support bracket solves all three problems while offering superior performance in demanding environments.

Weight Reduction:

A typical steel support bracket weighs 5 to 10 pounds. Our aluminum version weighs 2 to 4 pounds while maintaining equivalent or greater strength. For applications where weight matters, such as RVs, aircraft, and portable equipment, this reduction improves fuel efficiency, handling, and ease of installation.

Corrosion Resistance:

Steel brackets rust. Rain, salt spray, humidity, and chemical exposure attack steel relentlessly. A steel bracket eventually develops corrosion at bolt holes and sharp edges. Aluminum forms a protective oxide layer naturally, eliminating rust concerns entirely.

Thermal Conductivity:

Aluminum dissipates heat rapidly. A bracket near heat-generating equipment runs cooler than steel, protecting adjacent components and maintaining dimensional stability.

However, aluminum requires expert welding. This is where our TIG welding process becomes essential.

The TIG Welding Advantage for Support Brackets:

Not all welding processes produce a reliable aluminum support bracket. The component undergoes constant loads, vibration, and thermal expansion cycles. A weak weld will fail, potentially causing equipment damage or safety hazards.

Why TIG Welding Outperforms Other Methods?

MIG Welding is fast but deposits filler metal with microscopic porosity. For an aluminum support bracket, porosity creates crack initiation sites. Under repeated stress, cracks propagate until the bracket fails.

Stick Welding introduces flux residues that trap moisture against aluminum, accelerating galvanic corrosion. It also produces excessive heat input, warping the bracket and compromising mounting hole alignment.

Laser Welding is precise but expensive and creates a narrow, brittle heat-affected zone that can crack under dynamic loads.

TIG Welding solves all these problems. Our AC tig welding process with pulse control allows us to:

• Achieve full root penetration without burn-through
• Create smooth, consistent stack-of-dimes weld beads
• Control heat input precisely to prevent warping of the aluminum support bracket
• Use 5356 aluminum filler rod for maximum ductility and fatigue resistance

Every aluminum support bracket leaving our shop features TIG welds that are both visually beautiful and structurally sound. We inspect each weld under magnification to verify complete penetration and absence of defects.

Design and Construction of Our Aluminum Support Bracket?

A properly engineered aluminum support bracket balances load capacity, weight, fitment, and durability. Our fabrication process addresses each systematically.

Material Selection:

We fabricate every aluminum support bracket from 6061-T6 aluminum. This alloy offers:

• Yield strength: 40,000 psi
• Ultimate tensile strength: 45,000 psi
• Excellent weldability with 5356 filler rod
• Superior fatigue resistance for dynamic applications

For extreme-duty applications, we offer 7075-T6 aluminum. This aerospace-grade alloy delivers 70,000 psi yield strength and is available upon request for your aluminum support bracket order.

Standard Plate Thickness Options：

Bracket Geometry:

Our standard aluminum support bracket designs include:

• Flat plate brackets (L-shaped and T-shaped)
• Box section brackets (closed channel for maximum rigidity)
• Gusseted brackets (with triangular reinforcement at corners)
• Custom profile brackets (machined to your exact geometry)

For complex applications, we can incorporate multiple bends, compound angles, and internal stiffening ribs into your aluminum support bracket design.

Mounting Features:

We machine the following features standard on every aluminum support bracket:

• Precision-drilled mounting holes (size and pattern to your spec)
• Slotted holes for field adjustment
• Countersunk holes for flush mounting
• Threaded inserts (stainless steel for repeated assembly)
• Alignment pins for locating adjacent components

Custom Fabrication Process:

When you order an aluminum support bracket from our shop, you receive a component built specifically for your application, not a generic part adapted to fit.

Step 1: Design Consultation:

We collect your load requirements, mounting constraints, environmental conditions, and specific application needs.

Step 2: CAD Modeling:

Our engineering team creates a 3D model of your aluminum support bracket. We verify stress points and optimize geometry for maximum strength-to-weight ratio.

Step 3: Material Cutting:

Aluminum plate is precision cut using waterjet or CNC router. This produces clean edges ready for TIG welding without secondary finishing.

Step 4: TIG Welding Assembly:

Our certified welders assemble your aluminum support bracket using AC TIG with pulse. We weld in a sequence designed to minimize distortion, tacking components before applying full penetration beads.

Step 5: Post-Weld Heat Treating (Optional):

For maximum strength, we offer post-weld heat treatment to restore the temper lost during welding. This returns your aluminum support bracket to T6 condition.

Step 6: Final Machining:

After welding, we fly-cut all mounting surfaces flat and drill any remaining holes. This ensures your aluminum support bracket sits perfectly flush against mating surfaces.

Step 7: Surface Finish:

Options include mill finish, clear anodizing, black anodizing, powder coating in any RAL color, or chromate conversion coating.

Finishing Options:

After tig welding, we offer multiple finish options for your aluminum support bracket:

Mill Finish with Clear Anodize:

The standard option. Anodizing creates a .002″ thick aluminum oxide layer harder than paint. This aluminum support bracket resists salt spray, UV, and chemical exposure for decades.

Black Anodize:

For applications requiring minimal reflectivity, heat dissipation, or aesthetic matching with black equipment.

Powder Coat (Any Color):

We apply a durable polyester powder coat over a chromate conversion layer. This aluminum support bracket resists scratches and impacts.

Raw Aluminum:

For customers who prefer to apply their own coating. We ship your aluminum support bracket fresh from the TIG welding table, degreased but otherwise unfinished.
