Automatic Corrugated Roofing Sheet Machine (1330 mm G.C.): 14-Stand Roll Forming, Siemens PLC & Industrial Buying Guide (2026)

1. What is an Automatic Corrugated Roofing Sheet Machine (1330 mm G.C.)?

An Automatic Corrugated Roofing Sheet Machine (1330 mm G.C.) is a continuous heavy-duty cold roll forming production line specifically engineered to transform flat galvanized steel, Galvalume, and pre-painted metal coils into high-strength sinusoidal corrugated roofing and cladding panels. Designed and precision-built by Gagan Engineering Works in Khopoli, Maharashtra, this industrial production line features an overall machine footprint of 7 feet (W) × 35 feet (L) and operates at line speeds of 10 to 20 meters per minute with an automated cut-to-length tolerance of ±1.0 mm.

Unlike traditional manual or semi-automatic corrugation presses that stamp sheets stroke by stroke with high cycle times and non-uniform wave geometry, this 14-station continuous roll forming system processes master coils at the standard 1330 mm G.C. (Galvanized Corrugated) flat input strip width. As the steel strip passes through the 14 progressive forming stations, solid 90 mm diameter forged alloy shafts drive 168 mm outer diameter CNC-contoured forming rollers, gradually shaping 17 continuous sinusoidal waves without stretching the material, cracking protective zinc coatings, or inducing edge waviness.

The entire production line is governed by a centralized Siemens SIMATIC TP700 Touchscreen HMI and Siemens PLC automation console, paired with three Fuji Electric Frenic series VFDs and a high-resolution Omron optical rotary encoder. Sheet cutoff is executed by a heavy-duty exit-mounted back cutter manufactured from hardened Cr12MoV alloy tool steel, equipped with a manual slide lever for effortless test sample trimming and maintenance operations.

Whether you are an established roofing manufacturer upgrading to an automated line or an industrial entrepreneur entering the pre-engineered building (PEB) sector, this Automatic Corrugated Roofing Sheet Machine paired with our 10 Tons Hydraulic Decoiler provides a turnkey, high-output manufacturing solution backed by domestic Indian engineering and lifetime factory support.

2. Corrugated Sheet Profile Drawing: 1330 mm Feed, 17 Waves & 75 mm Pitch

The structural load-bearing capacity and weatherproofing performance of a corrugated roofing sheet depend directly on its wave geometry and dimensional uniformity. The Gagan Engineering Works 1330 mm G.C. line is engineered to produce the classic 17-wave sinusoidal profile from an input flat coil width of exactly 1330 mm, maximizing sheet coverage while maintaining optimum section modulus.

The engineering profile drawing below illustrates the precise dimensional relationships across the finished sheet:

• Flat Sheet Feed Width (Input): 1330 mm. This wide commercial feed width allows roofing fabricators to produce wider coverage panels from standard master coils compared to older 900 mm or 1000 mm narrow lines.
• Number of Sinusoidal Waves: Exactly 17 continuous repetitive sinusoidal waves (numbered 1 through 17 in the engineering schematic).
• Wave Pitch: 75 mm centre-to-centre between adjacent wave crests. This uniform 75 mm pitch distributes rainwater runoff evenly across the roofing surface and prevents localized ponding.
• Overall Formed Sheet Width: 1279 mm (+20 mm / -15 mm tolerance). This represents the total outer edge-to-edge dimension of the profiled sheet after transverse metal shrinkage across the 14 forming stations.
• Effective Cover / Laying Width: 1200 mm (+20 mm / -15 mm tolerance). When installed on purlins with standard 1.5 to 2 wave side laps, each sheet provides a net weather-sealed coverage of 1.20 meters.
• Installation Efficiency: The wide 1200 mm effective cover width reduces total panel count per roof by 20% to 28% compared to standard 900 mm sheets, saving contractors significant purlin fastening hardware, EPDM washers, and installation crane time.

3. 14-Station Progressive Roll Forming Physics: 90 mm Shafts & 168 mm Rolls

Roll forming a 1330 mm wide sheet into 17 distinct sinusoidal waves simultaneously requires careful management of transverse metal flow. Unlike narrow profiles, a 1330 mm strip undergoes significant transversal contraction as the flat metal is drawn into 17 sinusoidal valleys and crests (contracting from 1330 mm flat to 1279 mm formed width—a net transversal shrinkage of ~51 mm).

If this deformation is forced through too few stations (e.g., 8 to 10 stations), the excessive strain rate creates severe edge wave ('oil canning'), uneven wave depths, and zinc coating flaking on pre-painted or galvanized stock. Gagan Engineering Works engineers solve this by distributing the forming strain across 14 progressive forming stations:

1. Progressive Radial Infeed: In the initial 4 stations, the centre corrugations (waves 8, 9, 10) begin forming while the strip edges remain relaxed. Progressive outer waves (waves 5–7 and 11–13) engage in stations 5 through 9, and outer perimeter waves (waves 1–4 and 14–17) finish in stations 10 through 14. This progressive inward-to-outward metal drawing eliminates residual stresses and oil canning.

2. 90 mm Solid High-Tensile Shafts: Many low-cost fabricators use 65 mm or 75 mm hollow shafts made of mild steel EN8, which deflect under the continuous forming loads of 0.6 mm thick full-hard 550 MPa Galvalume coils. Gagan Engineering Works machines use solid 90 mm diameter forged steel shafts, CNC-turned and key-slotted for high torsional rigidity, ensuring zero shaft deflection across the full 1330 mm roll span.

3. 168 mm CNC-Contoured Rollers with Hard Chrome Mirror Finish: Forming rollers are CNC-lathe machined from high-grade EN31 / Cr12 alloy tool steel and vacuum-hardened. Each roller undergoes precision cylindrical grinding and 0.05 mm hard chrome electroplating with a mirror surface finish. This scratch-free surface protects the delicate primer and polyester paint finishes of colour-coated coils (PPGI and Galvalume), eliminating micro-cracking and zinc dust accumulation.

• Shaft Diameter: 90 mm solid forged alloy steel (heavy-duty keyed drive).
• Roller Outer Diameter: 168 mm precision CNC-contoured rolls.
• Roller Metallurgy: Vacuum-hardened EN31 / Cr12 high-carbon chromium alloy steel.
• Surface Treatment: 0.05 mm (50 micron) hard chrome electroplating with mirror polishing.
• Transmission: Heavy-duty industrial roller chains and sprockets powered by centralized helical bevel reduction gearbox.
• Forming Stand Frames: 30 mm thick solid steel vertical side plates mounted on heavy ISMB beam base frame (7 ft × 35 ft).

7. Exit-Mounted Heavy-Duty Back Cutter & Manual Lever Shearing Mechanism

The cutting station on a corrugated roll forming line is subjected to severe cyclic shear forces. If the shearing blades are flat or improperly aligned, the cut edge will crush the corrugated wave profile, creating burred ends that fail to interlock during roofing installation. The Gagan Engineering Works Automatic Corrugated Machine incorporates an engineered exit-mounted back cutter designed for continuous heavy-duty service.

Key engineering features of the back cutter system include:

1. Continuous Cutting Operation: Provides a strong, stable, and smooth cutting action engineered for non-stop automated manufacturing. Powered by a dedicated 4.0 kW hydraulic power pack with proportional flow control valves, the upper blade shears cleanly through the profiled sheet in under 1.2 seconds without stopping production momentum.

2. Mounted Directly at Machine Exit: Positioning the back cutter directly at the exit of station 14 guarantees the perfect shape accuracy of the corrugated profile. Because the sheet is supported by the final forming rolls as it enters the cutting dies, the panel cannot twist, bow, or deflect during the shearing stroke.

3. High-Grade Hardened Alloy Steel Blades: Both upper and lower cutting dies are CNC wire-cut to match the exact 17-wave sinusoidal contour. Manufactured from premium Cr12MoV vacuum heat-treated alloy tool steel (hardened to 60–62 HRC), the blades offer exceptional wear resistance, retaining razor-sharp cutting edges through hundreds of thousands of cuts without burring or chipping.

4. Auxiliary Manual Slide Lever Mechanism: In addition to automated PLC-triggered hydraulic cutting, the back cutter features a precision manual slide lever. By simply sliding the lever, the operator can manually cut the sheet at any moment. This capability is invaluable during initial coil threading, test sample extraction for thickness/profile verification, coil end splicing, or emergency cut-offs without needing to cycle through the automated touchscreen program.

• Cutting Action: High-speed, smooth hydraulic post-forming guillotine shear.
• Location: Mounted directly at the roll forming exit for flawless shape retention.
• Blade Material: Premium vacuum heat-treated Cr12MoV alloy tool steel (60–62 HRC).
• Contoured Profile: Exact 17-wave sinusoidal profile mating dies ensuring 100% burr-free cuts.
• Manual Override: Built-in manual slide lever for effortless manual cutoff and sample testing.
