30 Meters Per Minute Seamless Gutter Roll Forming Machine with 350H Steel Chassis and 50mm Solid Steel Plates

Developed through decades of rigorous field-proven engineering expertise and direct collaboration with international drainage contractors across North America, Europe, and Southeast Asia, the Howann Portable Automatic Seamless Rain Gutter Roll Forming Machine With Bearing For Wall Use is trusted by industrial builders and rainwater management specialists worldwide. Designed to eliminate the bottlenecks of manual gutter fabrication, this heavy-duty system seamlessly converts flat galvanized and color-coated steel coils into precision-profiled seamless rain gutters with exceptional structural rigidity and flawless hydraulic sealing.
Backed by strict ISO9001 manufacturing authoritativeness and full compliance with European CE safety standards, every Howann machine undergoes mandatory pre-shipment factory test runs and video audit verification. To ensure absolute customer trust and long-term operational security, Howann provides transparent tiered wholesale pricing ranging from $13,600 to $15,600 per set based on volume, backed by a solid 2-year factory warranty, secure payment protection, and responsive technical support from seasoned machinery engineers.

• Firsthand Jobsite Reliability: Designed alongside professional rainwater drainage contractors to ensure seamless profile precision, preventing water leakage and joint failure during heavy seasonal downpours.
• Deep Metallurgical Expertise: Incorporates 50 mm solid 45# quenched and tempered steel shafts paired with Cr12 mould steel cutting blades, ensuring clean shear cuts without scratching pre-painted or galvanized coil surfaces.
• Certified International Authoritativeness: Manufactured by Zhengzhou Howann Machinery — ranked among top industrial machinery suppliers with verified export excellence across the United States, Mexico, United Kingdom, Philippines, and Thailand.
• Uncompromised Transparent Trustworthiness: Supported by clear tiered pricing ($13,600–$15,600), secure payment protection, and verified 4.2/5 store satisfaction ratings with an on-time dispatch rate exceeding 97%.
• Rigid 350H Frame Stability: A heavy 2,200 kg mass-damping chassis featuring a robust 350H structural steel frame absorbs mechanical vibration during high-speed rolling and cutting, ensuring absolute profile symmetry over thousands of meters.

• Coil Infeeding & Guidance: Galvanized or color-coated steel strips are fed smoothly from the uncoiler into the precision alignment guide table with minimal lateral deviation.
• Progressive Cold Roll Forming: Calibrated roller stands gradually press the metal through multi-stage passes, transforming flat sheets into rigid seamless rain gutter profiles without coating damage.
• Digital Length Measurement: High-precision rotary encoders track linear travel distance in real time, signaling the PLC unit when the exact programmed gutter length is reached.
• Hydraulic Shear Cut-Off: The Cr12 mould steel hydraulic blade shears the formed gutter instantly with clean, burr-free square edges, eliminating secondary trimming requirements.

• Commercial & Residential Drainage Systems: Fabricating durable, leak-free seamless rain gutters for multi-story residential complexes, commercial warehouses, and industrial buildings.
• Mobile On-Site Fabrication: Transporting portable roll forming units directly to job sites to custom-roll continuous seamless gutters tailored to exact building dimensions.
• Regional Construction Supply Yards: Centralized manufacturing hubs supplying high-performance metal drainage solutions directly to local contractors.
