Metal Tubes Do Not Want To Be Bent

Transforming metal into intricate shapes isn’t easy. Tubing doesn’t bend effortlessly and is hard to fabricate to precise tolerances. Tube bending is sometimes described as a mysterious process with unavoidable trial and error. At STP, we've mastered the craft—it's a dash of science mixed with a pinch of finesse.

Delivering top-notch OEM products? Now, that's a challenge. The conditions are unforgiving, hours are long, and challenges are enormous. But when it comes to your tube bending needs, partnering with STP means one less thing on your worry list—your metal bends are in good hands.

We purchase material from reputable suppliers and verify compliance upon arrival. Our quality control team uses precise testing and inspection equipment to ensure every product surpasses customer specifications. Every order is audited for accuracy before shipment.

Bent Tube Application (A Few Examples)

HVAC Cooling System

Size:
5" OD, 0.25" Wall

Shape:
Round

Materials:
Stainless Steel

In the realm of HVAC systems, efficiency and reliability are paramount. When tasked with fabricating a cooling system for a large-scale HVAC project, we relied on our expertise in large-diameter bending and cutting.

The Challenge:
HVAC cooling tubes are often the last component designed in the HVAC system. Because of this, tubes require precise multi-radius bends in extremely tight windows. Mandrels are used not necessarily for aesthetics but to keep the inner diameters of the tube smooth without pockets that cause HVAC inefficiencies or UL misconformances.

Drawing upon our experience and advanced fabrication capabilities, we employed large-diameter bending techniques to shape the ductwork according to precise requirements. Our state-of-the-art bending machinery allowed us to achieve smooth curves and angles, ensuring optimal airflow and structural strength.

You could say, with our precision bending and cutting, we left our customer feeling cooler than the flip side of the pillow, even in the hottest of summers.

Tractor ROP Cab

Size:
4" OD, 0.5" Wall

Shape:
D-Shape

Materials:
Stainless Steel

Ah, the modern conveniences of tractor cabin design - where bent tube beats straight. You'll hear us say that over and over.

Tractor cabs, historically - rectangle cubes. Now with modern conveniences, it is standard for complex arcs to create the most optimal room for the operator, the most sleek design, while still keeping structural integrity at the forefront for rollover protection.

Did we mention it was complex?

The process starts with a sweeping bend in the main frame tubing, followed by a precise bend on another plane. This creates the foundation of the cab's curved shape. To maintain the sleek aesthetics while maximizing strength, D-shaped tubing is used throughout the frame. Laser cutting ensures perfectly sized holes for components, and welding is meticulously done after the bends to maintain the tight tolerances required for ROPS certification. It's a testament to modern engineering that we can achieve both style and safety in such a complex design.

Lawn Mower Frame

Size:
4" OD, 0.5" Wall

Shape:
Rectangle

Materials:
Stainless Steel

Another example of bent tube beats straight. A major lawn and garden manufacturer relied on us to convert straight, welded mower frames into bent tube magic.

We utilized mandrel bending for those eye-catching curves near the front wheels, and relying on robot welders for efficient, high-quality connections throughout the frame, deck support, and cross tubes.

Bent tubes not only reduce cost by streamlining the build process, but also create a lighter mower thanks to their inherent weight advantage. The strength isn't compromised either, as robot welders deliver precise and strong connections. But perhaps the coolest benefit? These bent tube designs are undeniably "badass," with clean lines and a look that screams power and innovation.

Powerwasher Handlebars

Size:
2" OD, 0.5" Wall

Shape:
Round

Materials:
Stainless Steel

When a leading manufacturer of pressure washers approached us with a challenge, we didn't just rise to the occasion; we blasted through it with precision tube bending, cutting, and end-forming expertise.

The Challenge:
It had to be durable, perfectly shaped, and seamlessly integrated with their cutting-edge power washer design.

We crafted the perfect curvature for optimal grip, control, ergonomics, and application alignment — we bent that metal like it was our morning yoga routine.

The "End-Flattening" end-forming design elevated their application from standard to superior. Not only do the aesthetics look badass, but flattening the ends increases their surface area, providing a more secure connection and compatibility with their mounting system.

Combine Safety Railing

Size:
2" OD, 0.5" Wall

Shape:
Round

Materials:
Mild Carbon Steel

When it comes to agricultural combines, safety isn't just a feature—it's a necessity. So when one of our customers in the ag industry (we hope their color doesn't give it way) came to us with a challenge, we didn't just rise to the occasion; we plowed through it with our signature blend of bending, cutting, and welding wizardry.

The Challenge:
Our customer needed a safety railing for their agricultural combine that could withstand the toughest conditions while providing maximum protection for operators. It had to be durable, perfectly fitted to the combine's design, and, of course, it had to look good.

With our state-of-the-art talent running state-of-the-art bending machines, we shaped the railing with precision, ensuring it hugged every contour of the combine like a well-fitted glove. No bend too sharp, no curve too subtle—we bent that metal like it was born to dance.

Welding was the pièce de résistance of our operation. With sparks flying and masks on, our expert welders brought everything together, fusing metal to metal with precision and finesse. The result? A safety railing that was strong, sturdy, and stunningly crafted.

In the world of ag machinery, where safety is paramount and performance is king, every detail matters. And when it comes to safety railings, we're the masters of our craft. With precision bending, cutting, and welding, we turned a simple railing into an agricultural masterpiece.
