Trapezoidal Profile Machine
Category: Roll Forming & Sheet Metal | Manufactured by Gagan Engineering Works, Khopoli, Maharashtra
The Trapezoidal Profile Machine manufactured by Gagan Engineering Works in Khopoli, Maharashtra is an automated continuous cold roll forming line engineered to manufacture precision trapezoidal-ribbed roofing panels, commercial wall cladding, and architectural siding sheets from pre-painted and galvanized steel coils. Engineered with 18 to 22 progressive forming stands driven by an 11 kW (15 HP) heavy helical geared motor with Variable Frequency Drive (VFD), the line progressively shapes 0.30 mm to 0.80 mm steel coils into straight, structurally rigid trapezoidal profiles with raised crests, flat valleys, and an integrated anti-capillary siphon groove on the overlapping rib. All forming rollers are precision CNC contour-turned from forged high-carbon EN31 / Cr12 alloy tool steel, vacuum-hardened, and electroplated with 0.05 mm hard chrome mirror finish to guarantee zero paint scuffing or surface scratching on PPGI, PPGL (Aluzinc 550 MPa), and colour-coated stock. The integrated optical rotary encoder length tracking system and PLC touchscreen automation deliver repeatable cutting tolerances within ±1.0 mm via a profile-contoured hydraulic shear with Cr12MoV vacuum-quenched blades (60–62 HRC). Supported by heavy 75/80 mm solid 40Cr transmission shafts, dual entry alignment guides, and matching 10-Ton motorized hydraulic decoilers, this line provides commercial roofing manufacturers, metal service centres, and industrial building fabricators with dependable 24/7 production output across India and global export destinations.

Frequently Asked Questions — Trapezoidal Profile Machine
What is a trapezoidal profile machine?
A trapezoidal profile machine is an automated continuous cold roll forming production line that shapes flat steel coils (such as PPGI, Galvalume, and GI) through progressive roller stands into profiled metal roofing and wall-cladding sheets featuring raised angular crests, flat drainage valleys, and sloped side webs.
What is a trapezoidal sheet making machine used for?
It is used to manufacture durable, weather-resistant metal panels for commercial building roofs, industrial warehouse sheds, factory workshop cladding, architectural facades, airport hangars, agricultural buildings, and exterior facings for insulated cold-room panels.
What is the difference between trapezoidal and corrugated roofing sheets?
Trapezoidal sheets feature raised angular ribs with flat valleys, providing higher section modulus and greater structural stiffness that allow wider support purlin spacing (1.2 m to 1.8 m) and include an anti-capillary drainage groove. Corrugated sheets feature rounded sinusoidal waves (typically 76 mm pitch), requiring closer purlin supports (0.6 m to 0.9 m) and generally serving rural, agricultural, or lower-load applications.
Which sheet materials can a trapezoidal machine process?
The line processes Pre-Painted Galvanized Iron (PPGI), Pre-Painted Galvalume (PPGL / Aluzinc AZ150, 550 MPa), Galvanized Iron (GI), colour-coated steel coils, and compatible roofing-grade aluminium alloys.
What material thickness can the machine handle?
Our standard line configuration handles sheet thicknesses from 0.30 mm up to 0.80 mm. Tooling clearances are precision-ground to form light commercial gauges as well as heavy structural cladding without paint cracking or edge wrinkling.
What is the production speed of a trapezoidal sheet making machine?
Our standard hydraulic stop-cut line operates at 18 to 25 meters per minute, producing approximately 8,000 to 12,000 linear meters (20 to 30 metric tons) per 8-hour shift. Continuous flying-shear lines operating at 35+ m/min can be configured upon request.
Can it manufacture customized roofing sheet profiles?
Yes. Gagan Engineering Works designs and CNC-machines roller tooling according to approved customer CAD/DWG drawings, accommodating customized rib heights, rib pitches, center-stiffening flutes, and effective cover widths.
Can the machine produce PPGI and Galvalume roofing sheets?
Yes. All roller surfaces are electroplated with 0.05 mm hard chrome mirror finish to eliminate friction scuffing, ensuring scratch-free forming on colour-coated PPGI and high-tensile Galvalume coils.
How does the hydraulic cutting system work?
The line features a profile-contoured hydraulic guillotine die fitted with vacuum-quenched Cr12MoV tool steel blades (60–62 HRC). An optical rotary encoder measures sheet length precisely; the line pauses momentarily (or matches speed in flying-cut setups), and the hydraulic cylinder shears the profiled sheet cleanly without burrs or edge deformation.
What determines the cost of a trapezoidal profile machine in India?
The cost depends on the number of roll forming stations (18 vs 22 stations), roller steel grade (EN31 vs Cr12MoV), shaft diameter (75 mm vs 80 mm), shear automation (stop-cut vs high-speed flying shear), and whether auxiliary equipment (such as a 10-Ton motorized hydraulic decoiler with coil car or auto-stacker) is included. Contact Gagan Engineering Works for an itemized factory quotation.
What information should a buyer provide for a quotation?
Buyers should specify: (1) target profile drawing with rib dimensions, (2) coil width and thickness range (e.g. 0.30–0.60 mm), (3) raw material type (PPGI, Galvalume, GI), (4) desired shift output, (5) decoiler requirements (5-Ton manual vs 10-Ton hydraulic), and (6) installation destination city or export seaport.
What installation, training and maintenance requirements should a buyer consider?
The line requires a flat reinforced concrete foundation (approx. 25 m x 3 m footprint) and a 415V 3-phase industrial power connection. Gagan Engineering Works provides foundation layout drawings, on-site mechanical alignment, electrical commissioning, operator training, a 1-year warranty, and readily available spare tooling parts from our Khopoli works.
