Yarım Yuvarlak Oluk Rulo Şekillendirme Makinesi

A half round gutter roll former is specialized equipment designed to shape continuous flat metal coils into seamless, semi-circular (U-shaped) gutters. These gutters are highly popular for high-end custom homes, historic building restorations, and architectural designs requiring a classic aesthetic.

Because half-round gutters are often chosen for premium aesthetics, the machines are specifically engineered to handle high-end materials without scratching them. Common materials include:

• Copper: 16 oz. to 20 oz. (highly popular for half-round profiles)

• Alüminyum: 0.027″ to 0.032″ thickness

• Galvanized or Pre-painted Steel: 24 to 26 gauge

• Zinc: Standard roofing gauges

Generally, no. Because the semi-circular geometry and curled bead require highly precise, dedicated roller tooling, most half-round machines are designed to produce a single, fixed size (most commonly 5-inch or 6-inch). To produce multiple sizes, manufacturers usually require separate machines or a large factory-grade half round gutter roll former machine with interchangeable tooling cassettes.

The half round gutter roll former machine features a specialized set of edge-forming rollers that incrementally curl the outer lip of the metal into a tight, continuous tube known as the “bead.” This bead adds critical structural rigidity to the U-shape. Depending on how the machine is ordered, it can be configured to roll a traditional forward bead (curled outward) or a reverse bead (curled inward).

Yes, half-round roll formers come in both configurations:

• Portable Machines: Compact enough to be mounted inside a truck or trailer, allowing contractors to run continuous, seamless gutters directly at the job site.

• Stationary/Factory Machines: Heavier, highly automated lines meant for high-volume, in-plant production of cut-to-length sections for distribution.

Cutting a curved U-shape requires specialized mechanisms to prevent deformation.

• Portable machines typically use a heavy-duty, manually operated rotary shear (or “cutoff”) that precisely slices along the contour of the metal.

• Factory machines use a hydraulic guillotine cutter with a blade custom-machined to match the exact half-round and bead profile, ensuring a clean, dent-free cut.

Portable half-round machines used on job sites typically run at speeds of 30 to 45 feet per minute (approx. 9 to 14 meters per minute). Stationary factory-grade machines can operate at faster speeds, generally around 15 to 20 meters per minute, controlled seamlessly by a PLC system.
