Looking for a one-stop solution for large-span roofing panels? Our Long Span Roll Forming Machine is a fully automated line that handles it all: decoiling, roll forming, on-site arching, seaming, and cutting. Built for flexibility, it works with a wide range of material thicknesses, so you can adapt to any project requirement.

The operational principle of the Long Span Roll Forming Machine involves continuously feeding coiled color-coated steel sheets through a series of rollers to form a specific panel profile, while simultaneously imparting a precise curvature to the material. On-site, these panels are joined together via mechanical interlocking (seaming); this method creates a robust, large-span roofing structure that requires no support from traditional beams or purlins.

Our standard models—specifically the 305, 680, and 800 series—are the most widely utilized and represent our best-selling conventional products, distinguished by their rapid delivery times and ease of maintenance.

Application Areas

The Long Span Roll Forming Machine is widely applied in the construction of:

[Area 1: Residential]-Villas

[Area 2: Industrial & Warehousing]-Aircraft Hangars, Storage Facilities, Factory Buildings

[Area 3: Public & Commercial]-Sports Venues, Markets, Parking Facilities

Shared Advantages

Ultra-Long Span Capability:Roof panels produced by this type of machine can achieve standard spans of up to 42 meters, creating interior spaces that are completely free of beams and columns.

Exceptional Production Efficiency:Featuring a high degree of automation, the equipment typically forms straight panels at speeds of around 15 meters per minute, while the curving and seaming processes maintain speeds of 10–13 meters per minute—making it ideally suited for large-scale construction projects.

Vehicle-Mounted Mobile Design:Our equipment is designed as a "vehicle-mounted" or trailer-based unit, allowing it to be driven directly to the construction site for on-site production; this significantly reduces the logistical challenges and potential damage associated with transporting large, finished roof panels.

Comparison of Three Major Models (305 / 680 / 800)

The following is a comparison table for the three models:

Selection Recommendations

Choose Model 305

Smaller Project Spans: If your project span is within 26 meters, this machine is fully capable of meeting your requirements.

Stable Power Supply: This model is fully electric and requires a stable industrial power source for operation.

Prioritizing Portability and Economy:It is the lightest of the three machines (approx. 8 tons), making it ideal for scenarios with limited budgets or sites where equipment weight is a critical constraint.

Choose Model 680

Medium Span Requirements: Suitable for projects with spans ranging from 26 to 36 meters, offering a wider coverage area than the Model 305.

Stable Power Supply: Also featuring a fully electric design, it is well-suited for fixed-site workshops or construction sites where access to a power grid is available.

Balanced Cost-Effectiveness: Strikes an optimal balance between forming width and machine weight, making it the ideal choice for the construction of most standard large-scale warehouses or industrial plants.

Choose Model 800

Extra-Large Span Requirements: This is the only model capable of covering spans up to 42 meters, making it perfect for constructing large sports arenas, expansive marketplaces, or extra-wide industrial facilities.

Remote or Off-Grid Operations:Equipped with a 4-cylinder, 40 HP diesel engine, it requires no external power source—making it highly suitable for remote regions or field construction sites where power infrastructure is underdeveloped.

Mobile Construction Needs:Although it is the heaviest of the three models (13 tons), its self-contained power source provides superior operational independence and facilitates easier relocation between sites.
