The Keel Roll Forming Machine is a fully automatic, high-efficiency cold roll forming equipment specially designed for manufacturing metal keels — the core supporting component of building decoration and light steel structure projects, widely used in global commercial buildings, residential buildings, industrial workshops, and interior decoration projects. As a key equipment in the construction, decoration, and metal processing industry, it adopts advanced servo control, precision progressive roll forming, and on-line hole punching technology to process high-quality metal coils (hot-dip galvanized steel, cold-rolled steel, light gauge steel) into high-strength, corrosion-resistant, and dimensionally accurate metal keels of various types and specifications, including standard C-type, U-type, Omega-type, and special-shaped keels, as well as stud and track profiles for drywall installation.

With the rapid development of global construction industry towards intelligence, environmental protection, and high efficiency, light steel structure and modular construction have become mainstream trends, driving the growing demand for high-quality metal keels. Metal keels are the “backbone” of interior decoration and light steel framing, used to support gypsum boards, ceiling panels, wall panels, and insulation materials, and are widely applied in ceiling systems, partition walls, drywall installation, and light steel structure framing. Our Keel Roll Forming Machine is engineered to produce all types of metal keels with quick parameter adjustment, supporting standard and customized specifications, ensuring compatibility with global construction industry standards (including ICC-ES, ASTM, CE) and diverse project requirements. It is the ideal production equipment for keel manufacturers, building material suppliers, decoration companies, and export-oriented processing enterprises across the globe.

Core Components of Our Keel Roll Forming Machine

Heavy-Duty Hydraulic Uncoiling System: Built for large-size metal coils used in keel production, this system is equipped with a hydraulic expansion uncoiler with a load capacity of 3-8 tons, supporting coil widths ranging from 100-500mm and material thickness of 0.5-2.0mm — covering the common thickness range of light gauge steel keels in global markets. It features automatic hydraulic deviation correction, pressure holding, and anti-slip feeding rollers, paired with a reinforced feeding guide bridge to prevent material wrinkling, scratching, or misalignment during high-speed feeding. It is fully compatible with all common anti-corrosion metal coils for keel manufacturing, including hot-dip galvanized steel and cold-rolled steel, ensuring smooth and stable feeding for long-term high-intensity production runs.

Precision Leveling & Servo Feeding Unit: Equipped with 9-15 groups of high-precision leveling rollers, this unit effectively eliminates curling stress and surface unevenness of raw metal strips, guaranteeing the material is perfectly flat before entering the forming station — a key factor to ensure the straightness and load-bearing capacity of finished keels. It supports adjustable leveling intensity for different material thicknesses and hardness, especially for light gauge steel used in drywall stud and track production. The servo-driven precision feeding system ensures accurate feeding length and constant speed, matching the high-speed forming and punching process without slipping or position deviation, and ensuring consistent dimension and structure of each metal keel.

On-Line Flying Hole Punching Unit: Punching is a core step in keel production (for installation holes, connection holes), and our machine is equipped with an advanced servo-driven on-line flying hole punching system that realizes synchronous punching during continuous forming without stopping production. The punch and die set are made of Cr12MoV or Cr12 alloy steel, processed via precision CNC machining and integral quenching, with a hardness of HRC 60-65, ensuring wear resistance and long service life. It can punch round holes, square holes, and slotted holes with uniform size and spacing, with punching accuracy within ±0.1mm, and the punching position, hole size, and spacing can be flexibly set via the PLC touch screen to meet the installation requirements of different keel types and construction scenarios.

Multi-Type Keel Forming Main Unit: As the core of the entire machine, the forming unit adopts a rigid thick-walled steel frame with overall stress relief treatment, composed of 12-26 groups of precision forming roller stations — the number of stations can be adjusted according to the complexity of the keel profile (such as Omega-type and special-shaped keels). The forming rollers are crafted from high-grade 45# hardened steel or GCr15 bearing steel, processed via precision CNC machining, integral quenching and tempering, and hard chrome plating, with a hardness of HRC 58-62, delivering excellent wear resistance and a service life of over 800,000 meters. Driven by a high-power servo motor and precision gearbox transmission, the rollers are specially designed to form C-type, U-type, Omega-type, and special-shaped keels in one pass, with quick switching between types by adjusting parameters or replacing partial roller modules — reducing mold change time from 4 hours to 30 minutes, greatly improving production flexibility for multi-profile production needs.

Edge Trimming & Flanging System: The edge quality and flanging structure are critical to the load-bearing capacity and installation safety of metal keels. Our machine is equipped with a precision edge trimming and flanging unit, which strictly controls the edge flatness and ensures smooth, burr-free edges, while forming integral flanging on the keel surface to enhance structural strength and installation stability. The Omega-type keels produced by our machine, with their unique “Ω” shaped cross-section design, have excellent bending stiffness and load-bearing capacity, suitable for high-demand ceiling and wall framing projects. The trimming and flanging speed is synchronized with the production line, ensuring no impact on production efficiency.

High-Precision Hydraulic Cutting System: To match the high-efficiency forming and punching speed, our machine adopts advanced servo-controlled hydraulic cutting technology, enabling non-stop fixed-length cutting during continuous production. The cutting blades are made of heat-treated high-strength alloy steel, ensuring smooth, burr-free cutting edges and no keel deformation. Cutting accuracy is controlled within ±0.3mm, and the cutting length can be freely adjusted between 1-6 meters via the PLC touch screen, adapting to standard keel lengths and customized project requirements for construction and decoration.

Automatic Discharging & Stacking Mechanism: Designed for keels of different sizes and types, this unit features an inclined soft-contact discharge rack and pneumatic stacking device with rubber pads, avoiding surface scratches and edge damage to the finished keels. It automatically arranges and stacks finished metal keels neatly, reducing manual handling labor and product damage, while protecting the anti-corrosion coating integrity and overall product appearance. The stacking height is adjustable, adapting to different storage and transportation needs, and the stacked keels are easy to pack and ship, suitable for bulk export orders.

Intelligent PLC Control System: The full production line is controlled by a renowned international brand PLC (Siemens/Mitsubishi/Delta) with a user-friendly large touch screen operation panel, supporting multi-language switching including English, Spanish, Arabic, French, Russian, and Portuguese. It realizes full-process automatic control, with functions such as production counting, fault self-diagnosis, emergency stop, parameter memory, keel type/size adjustment, and production speed regulation — complying with EN ISO 12100 mechanical safety design standards and EN 60204-1 electrical safety requirements. The system stores multiple sets of processing parameters for different keel models, enabling quick switching between products, and is simple to operate, requiring only 1-2 workers to monitor. Additionally, it can be equipped with an IoT module to upload production data to the cloud, helping enterprises realize digital management of the production process.
