15 m/min PLC-Controlled 5.5 kW Roll Forming Machine for Automatic Square Downspout and Rain Gutter Production

Manufactured by howann, the Automatic Square Downspout & Rain Gutter Roll Forming Machine is engineered to meet the demanding workload, high-volume production schedules, and strict hydraulic sealing tolerances required by modern architectural rainwater management systems. Downspouts and rainwater gutters serve as the primary defensive barrier protecting commercial and residential building foundations from water infiltration; producing uniform, symmetrical square profiles requires exceptional mechanical stability, precise roller alignment, and flawless lock-seam closure.

Constructed upon a heavy-gauge 350H welded steel structural base weighing a substantial 2,200 kg, the howann profiling station absorbs resonant vibrations during high-speed rolling passes. It integrates 50mm solid drive shafts made from quenched and tempered 45# forged steel, high-hardness Cr12 mould steel cutting blades with thermal quenching treatment, and an advanced programmable PLC touch-screen control system to deliver clean, burr-free downspout sections ready for immediate jobsite installation and elbow connection.

• Firsthand Drainage Contractor Experience: Developed from extensive global jobsite feedback—ensuring precise lock-seam geometry that prevents water leakage during heavy downpours and seasonal storms.
• Deep Engineering Expertise: 50mm solid shafts paired with 350H structural steel frames provide exceptional torsional rigidity, preventing roller shaft flex during high-speed rolling and maintaining wall-thickness symmetry.
• Industry Authoritativeness: Produced under strict ISO9001 quality protocols in a certified 9,700 m² manufacturing facility, meeting rigorous CE safety directives and international export compliance standards.
• Uncompromised Trustworthiness: Supported by transparent tiered wholesale pricing ($12,500 to $20,500 per set based on volume), a solid 2-year warranty, and mandatory pre-shipment factory test runs with video verification audit reports.
• Advanced Hydraulic Cutting Reliability: Integrates a 40# hydraulic oil system and high-hardness Cr12 mould steel blades to deliver clean, square cuts without distorting the profile end-shapes.

• Coil Entry & Guidance: Galvanized or color-coated steel coils are uncoiled smoothly into the machine entry guide table with minimal lateral deviation.
• Progressive Cold Roll Forming: Calibrated rolling stations progressively bend and shape the metal strip through multi-stage passes, transforming flat sheets into rigid square downspout tubes with lock seams.
• Automated Length Measurement: Rotary encoders track linear travel distance in real time, signaling the PLC controller when the exact programmed downpipe length is achieved.
• Hydraulic Post-Cutting: The Cr12 mould steel hydraulic blade shears the formed profile instantly with clean, square edges, eliminating secondary trimming requirements.

• Commercial Building Drainage Systems: Fabricating durable square downspouts for multi-story office complexes, warehouses, and distribution centers.
• Residential Rainwater Management: Producing precision downpipe profiles that integrate seamlessly with residential gutter and elbow installations.
• Regional Construction Supply Yards: Centralized manufacturing hubs supplying custom-cut metal drainage solutions directly to local contractors.
