R72 Roofing Sheet Making Machine

R72 Roofing Sheet Making Machine – High-Precision Industrial Roofing Solution

The R72 Roofing Sheet Making Machine from Cangzhou Zhongtuo delivers enterprise-grade performance for industrial and residential applications. With 18 forming stations, our machine processes material from 0.3 to 0.8 mm at speeds up to 15 m/min. The robust 16 mm H-beam frame and 70 mm shaft diameter ensure zero deflection during production. Equipped with a Delta PLC control system and hydraulic cutting accuracy of ±2 mm, this 5.5 kW powerhouse weighs just 3.5 tons yet delivers consistent results for warehouses, coastal housing, and agricultural buildings across 150+ countries.

What Makes This Machine Different?

Your roofing production needs more than just metal bending. You need precision, durability, and speed.

Our machine solves three critical problems you face daily:

Profile accuracy matters. The 18-station progressive forming system gradually shapes your metal without stress cracks. Each roller is manufactured from GCr15 bearing steel with 0.05 mm hard chrome coating. This prevents surface scratches on your expensive PPGI coils.

Cutting quality impacts your reputation. The hydraulic shearing system uses Cr12Mov mold steel, heat-treated to HRC 58-62. You get burr-free edges that last over 500,000 cycles before maintenance. Your customers notice the difference.

Production speed affects your bottom line. At 15 meters per minute with automated length control, you produce more sheets in less time. The Delta PLC touchscreen lets your operator set precise measurements. No more manual measuring mistakes.

Technical Specifications You Can Trust

Where Your Investment Pays Off?

Large industrial warehouses benefit most from the R72 profile. The superior moment of inertia means wider purlin spacing. You save on structural steel costs while maintaining roof integrity under heavy loads.

Coastal construction projects demand corrosion resistance. Our gentle roller design processes Aluzinc and marine-grade coils without damaging protective layers. Your roofing withstands high-salinity environments for decades.

Agricultural facilities require long, leak-free sheets. The machine produces custom lengths over 12 meters continuously. Fewer overlaps mean fewer potential leak points in your barns and silos.

Built on a Decade of Innovation

Since 2014, Cangzhou Zhongtuo has focused exclusively on cold roll forming technology. We became a national-level high-tech enterprise in 2022. Our partnership with Yanshan University's Cold Rolled Strip Equipment Research Center brings advanced simulation and AI optimization to every machine we build.

We hold ISO 9001, CE, and CAS certifications. These aren't just badges—they represent thousands of hours of testing and refinement.

Our machines operate in over 150 countries. From European factories to Southeast Asian workshops, builders trust our equipment daily.

Smart Features That Save You Money

Intelligent roller design comes from finite element analysis and AI simulation. Our research team optimizes every curve to minimize material stress. You get consistent profiles, sheet after sheet.

Remote monitoring capability lets you diagnose issues before they stop production. Cloud-based systems provide real-time data on machine performance. Your maintenance team works smarter, not harder.

Virtual commissioning technology reduces installation time. We test your machine digitally before it ships. You start producing quality sheets faster after delivery.

Quality Control You Can Verify

Every R72 Roofing Sheet Making Machine undergoes rigorous testing:

Profile tolerance testing ensures ±1 mm cover width and ±0.5 mm rib height accuracy. Your sheets fit together perfectly during installation.

Hardness testing confirms roller consistency at HRC 55-60. This guarantees long service life even with continuous operation.

Run-out measurement keeps shaft deviation below 0.05 mm. Your sheets come out straight, not twisted.

Hydraulic load testing runs for two hours continuous to verify stable pressure. The system maintains 10-12 MPa without overheating, even in hot climates.

Common Questions Answered

Can the machine handle thickness changes without adjustment?

The machine processes the full 0.3-0.8 mm range. For optimal precision when switching between extreme thicknesses, we recommend gap adjustment. This protects your rollers and maintains profile accuracy.

What about high-tensile steel processing?

Standard Cr12Mov blades last 3-5 years with normal materials. For G550 high-tensile steel, upgrade to SKD11 blades. They prevent chipping and ensure clean cuts.

How does it handle unstable power supply?

The electrical cabinet includes overload protection and phase failure relays. We recommend installing a voltage stabilizer in areas with frequent fluctuations. This protects your VFD and motors.

What maintenance does the hydraulic system need?

Replace hydraulic oil every 12 months or 2,000 working hours. Use #46 anti-wear hydraulic oil. Clean the filter regularly to protect solenoid valves from debris damage.

The sheets come out curved—what's wrong?

This indicates uneven pressure in final forming stations. Adjust the straightening device (Turk's head) at the exit. The side screws correct lateral bowing for straight output.
