Metal Trapezoidal Plate Cold Bending Machine Product Description
The Metal Trapezoidal Plate Cold Bending Machine is a high-efficiency, specialized cold bending equipment, specifically designed to continuously and stably produce high-precision metal trapezoidal plates through cold bending technology. It integrates full-automatic feeding, precise cold bending forming, accurate cutting, and orderly stacking into one integrated unit, realizing full-process automation with minimal manual intervention, which boosts production efficiency by up to 70% compared to semi-automatic models. As a core equipment in the metal forming and construction industries, it is mainly used for manufacturing metal trapezoidal plates, widely applied in residential buildings, industrial warehouses, workshops, stadiums, transportation infrastructure, and other construction projects, especially suitable for large-scale mass production of metal trapezoidal plates.
Equipped with an advanced PLC automatic control system featuring a user-friendly touchscreen interface, the machine allows operators to set metal trapezoidal plate-specific parameters (including plate length, cold bending speed, trapezoidal rib height, and plate thickness) with one click, and the system will automatically complete the entire cold bending and cutting process. It can store 50+ sets of production recipes, enabling quick switching between different specifications of metal trapezoidal plates without time-consuming reconfiguration. Combined with high-precision servo motors and automatic hydraulic cutting technology, the intelligent control system ensures the cutting length tolerance is strictly controlled within ±0.5mm, maintaining consistent profile dimensions, smooth edges free of burrs, and uniform trapezoidal shapes—effectively ensuring the structural stability and dimensional accuracy required for metal trapezoidal plate applications.
The machine boasts a robust structural design optimized for long-term stable operation, specifically tailored to the cold bending processing characteristics of metal materials. Its frame is made of H-beam welded steel,经过 tempering treatment to enhance structural stability and load-bearing capacity, effectively avoiding deformation during high-speed continuous cold bending operation. The precision-machined cold bending rollers (core component of plate forming) are crafted from 45# steel with chrome plating or D2 hardened steel, featuring a smooth and wear-resistant surface. With excellent wear resistance, the rollers can maintain stable cold bending precision for over 10 years even under high-speed continuous operation. The cold bending section is equipped with 12-24 sequential roller stations (depending on the complexity of the metal trapezoidal profile), which gradually bend the metal coil into the desired trapezoidal shape through incremental cold deformation, ensuring consistent profile quality and structural rigidity of each metal trapezoidal plate.
The cold bending process effectively preserves the mechanical properties of the base metal, ensuring the final metal trapezoidal plates have strong structural rigidity, excellent load-bearing performance, reliable connection tightness, and superior corrosion resistance—suitable for various harsh working environments. The machine is specially designed with an automatic tension control system for metal coils, which can adjust the feeding tension in real time to avoid coil deformation, ensuring the finished metal trapezoidal plates have a smooth, uniform surface and stable dimensional accuracy. It is compatible with a variety of metal materials, including color-coated steel (PPGI/PPGL) coils, galvanized steel coils, aluminum alloy coils, and plain steel coils, meeting the diverse material needs of different projects.
Versatile and adaptable to diverse project design needs, the Metal Trapezoidal Plate Cold Bending Machine mainly processes color-coated steel, galvanized steel, aluminum alloy, and plain steel coils. It can handle material thickness ranging from 0.2-2.0mm, with a customizable metal trapezoidal plate width of 300-1200mm and an adjustable trapezoidal rib height of 15-80mm—perfectly matching different load-bearing requirements, installation scenarios, and architectural designs. It is ideal for producing lightweight, corrosion-resistant, and easy-to-install metal trapezoidal plates, catering to the needs of residential, industrial, public building, and infrastructure projects.
With an adjustable automatic production speed of 10-60 m/min (depending on configuration), the machine enables continuous mass production, delivering an output capacity of 300-600 ㎡/h—making it perfectly suited for large-scale construction projects and prefabricated component production lines. It adopts a low-noise design (below 78 db) and is equipped with full-length safety guards, emergency stop switches, and automatic fault alarm devices, ensuring safe and stable operation in industrial environments. Additionally, the machine complies with ISO and CE certifications, comes with a 12-month warranty, and provides global on-site installation, professional technical training, and comprehensive after-sales support, including spare parts supply and remote troubleshooting assistance for the control system and cold bending components.
Whether for small-scale workshops or large-scale manufacturing plants, the Metal Trapezoidal Plate Cold Bending Machine offers a cost-effective, high-performance solution for metal trapezoidal plate production. Its integration of full-process automation, high-precision cold bending, and multi-material compatibility helps enterprises significantly improve production efficiency, reduce labor costs and production errors, and enhance product quality—making it an indispensable equipment in the modern metal cold bending and construction industries.

Advantages of Roll Forming A Metal Part
There are several advantages of using roll forming for your projects:
- The roll forming process allows operations such as punching, notching, and welding to be performed in-line. Labor cost and time for secondary operations are reduced or eliminated, reducing part costs.
- Roll form tooling allows for a high degree of flexibility. A single set of roll form tools will make almost any length of the same cross-section. Multiple sets of tools for varying length parts are not required.
- It can provide better dimensional control than other competing metal forming processes.
- Repeatability is inherent in the process, allowing easier assembly of roll formed parts into your finished product, and minimizing problems due to “standard” tolerance build up.
- Roll forming is typically a higher speed process.
- Roll forming offers customers a superior surface finish. This makes roll forming an excellent option for decorative stainless steel parts or for parts requiring a finish such as anodizing or powder coating. Also, texture or pattern can be rolled into the surface during forming.
- Roll forming utilizes material more efficiently than other competing processes.
- Roll formed shapes can be developed with thinner walls than competing processes
Roll forming is a continuous process which converts sheet metal into an engineered shape using consecutive sets of mated rolls, each of which makes only incremental changes in the form. The sum of these small changes in form is a complex profile.
