Factory Price Automatic Double Layer Roof Panel Roofing Roll Forming Machine 15-20m/min

The double layer IBR roof panel roll forming machine is developed for manufacturers that need to produce two different IBR-style corrugated roof sheet profiles on a single compact line. This cold roll forming system incorporates two separate forming levels—an upper deck and a lower deck—within one shared frame, enabling operators to alternate between profiles without replacing the machine or changing major tooling components.

By integrating two roofing panel forming units into one structure, the equipment helps save valuable workshop space and lowers the overall equipment investment. It is commonly adopted by metal roofing producers, steel structure contractors, and building material manufacturers that supply roof panels for different regional specifications.

Unlike a single-profile forming rolling machine, the double layer roll former is equipped with two separate roll forming systems. Each layer has its own forming stations, rollers, transmission system, and cutting unit. Only one layer operates at a time, ensuring stable forming performance and avoiding mechanical interference.

Profile selection is achieved by feeding the steel coil into the required forming level. This design allows fast production switching while maintaining the same forming accuracy and reliability as a conventional single-layer roll forming machine.

The IBR roof panel is a popular corrugated roof panel profile known for its strong load-bearing capacity and efficient water drainage. The design typically includes deep main ribs combined with intermediate stiffening ribs, which improve structural strength and resistance to deformation.

IBR corrugated roof panels are roll formed from galvanized steel or pre-painted steel coils, with common thickness ranges from 0.3 mm to 0.8 mm. Different IBR profiles may vary in rib height, pitch, and effective width, depending on regional construction standards.

These panels are widely applied in:

• Industrial and commercial roofing systems
• Steel structure buildings and warehouses
• Agricultural and utility roofing projects
• Large-span metal roof installations

With a double layer IBR roof panel roll forming machine, manufacturers can produce two different IBR profiles to meet diverse market demands.

A standard double layer IBR roof panel roll forming machine consists of:

• Steel coil decoiler
• Material feeding and guiding system
• Upper layer roll forming stations
• Lower layer roll forming stations
• Independent hydraulic cutting units
• PLC control system with touch screen interface
• Finished panel run-out tables

During operation, the steel strip passes through a series of forming stands where it is progressively shaped into the required profile. Once the programmed length is reached, the hydraulic cutting unit automatically completes the cut, delivering accurate dimensions and clean cutting edges.

The cold roll forming method maintains stable profile dimensions throughout production, ensuring reliable quality and making the line well suited for long, continuous manufacturing runs.

• Two IBR corrugated roof panel profiles produced on one machine
• Compact design that saves factory space
• Independent forming and cutting systems for each layer
• Stable roll forming performance for long production runs
• PLC-controlled operation for precise length and speed control
• Compatible with galvanized and color-coated steel coils

As a professional roll forming machine, it is designed to balance flexibility, efficiency, and long-term durability.

This double layer IBR roof panel roll forming machine can be customized according to customer requirements, including:

• Coil width and panel effective width
• Material thickness range
• Number of roll forming stations per layer
• Chain-driven or gearbox-driven transmission
• Hydraulic cutting mold dimensions
• Electrical components and PLC brand options

These configurations allow the roll forming machine to meet different national and regional roofing specifications.

The double layer IBR roof panel roll forming machine is suitable for:

• Roofing sheet manufacturing factories
• Steel structure production lines
• Construction material suppliers
• Roll forming machine trading companies

It is particularly ideal for manufacturers looking to expand their product range while minimizing equipment redundancy and workshop space usage.

For manufacturers that need to produce several types of corrugated roof panels, a double layer roll forming system provides a cost-effective and efficient option. It increases production versatility while maintaining stable forming performance and consistent product quality.

Built on well-established cold roll forming technology and practical industry experience, this double layer IBR roof panel machine enables dependable operation and supports efficient, scalable production of metal roofing panels.
