The gutter forming machine is a specialized cold bending equipment for building roof drainage systems. It can continuously roll galvanized sheet, color coated sheet, aluminum sheet and other rolls into K-shaped, U-shaped, and irregular gutters (eaves gutters) for roof rainwater collection and diversion. It is widely suitable for buildings such as factories, villas, photovoltaic greenhouses, public venues, etc. It is the core equipment for efficient processing of drainage system profiles.

Equipment structure composition

• Uncoiler: carrying coil material (inner diameter 508mm, outer diameter ≤ 1200mm), pneumatic brake, automatic feeding, compatible with standard steel/aluminum coils.
• Leveling guide mechanism: Multi roller leveling+double-sided guide wheels, correcting the flatness of the board, preventing deviation and jamming, and ensuring stable feeding.
• Forming host: 14-22 rows of progressive rolling rolls, gradually cold bending forming, ensuring the standard curvature of the gutter, accurate size, and no scratches on the surface.
• Hydraulic cutting system: Cr12MoV quenched blade, guided column shear, smooth and burr free cut, no deformation of pipe mouth, cutting accuracy ± 1mm.
• PLC intelligent control system: touch screen operation, parameter memory, automatic counting, length measurement, fault alarm, supports one click start stop, single person on duty.
• Discharge rack: for receiving and stacking finished products, with optional automatic stacking to prevent surface scratches and facilitate transportation.

Core advantages

• High strength frame, stable and durable: H-shaped steel is welded as a whole, with stress relief treatment after welding. It does not deform or shake under long-term heavy load and is suitable for continuous production.
• Multi specification customization, one machine for multiple uses: can produce K-shaped, U-shaped, and irregular gutters, and can adapt to different sizes by changing the rollers, meeting the needs of multiple scenarios such as residential, factory, and photovoltaic.
• Precision molding, reliable quality: Progressive rolling process, uniform curvature and good straightness of the gutter, no damage to the anti-corrosion layer of the board, long service life.
• Intelligent control, efficient and worry free: PLC+touch screen, intuitive parameter settings, fault self checking alarm, beginners can get started in 1 hour, reducing labor costs.
• Efficient production, high cost performance: one-time feeding, continuous molding, automatic cutting, daily production can reach 1500-2500 meters, suitable for large batch orders, with low overall cost.

Performance characteristics

• Stable molding: The pattern is regular, the size is precise, the surface is flat, there are no scratches or deformations, and the drainage is smooth without water accumulation.
• Wide material compatibility: Suitable for various types of plates such as galvanized, color coated, aluminum, stainless steel, etc., to meet the anti-corrosion and cost requirements of different projects.
• Simple operation and maintenance: simple structure, few vulnerable parts, only regular lubrication is required for daily use, low maintenance costs, and low continuous operation failure rate.
• Easy installation: The finished gutter has tight overlap, simple installation, high construction efficiency, and is suitable for various roof drainage constructions.

Application scope

• Industrial buildings: Rainwater collection and diversion on the roofs of steel structure factories, warehouses, and locomotive depots.
• Civil buildings: roof drainage systems for residential buildings, villas, and new rural construction.
• Agricultural facilities: photovoltaic greenhouses, greenhouse eaves gutter drainage, and rainwater recovery.
• Public works: sports venues, exhibition halls, municipal building roof drainage, and sponge city rainwater collection.
