Automatic Roofing Sheet Crimping Machine manufactured by Gagan Engineering Works Khopoli Maharashtra India

The Automatic Roofing Sheet Crimping Machine manufactured by Gagan Engineering Works in Khopoli, Maharashtra is a high-speed hydraulic curved profile forming machine designed for bending pre-painted galvanized iron (PPGI), galvanized steel (GP), and aluminium roofing panels into smooth, uniform curved arches. Extensively deployed for constructing curved factory sheds, warehouse barrel canopies, petrol pump forecourts, aircraft hangars, agricultural grain silos, and modern architectural curved roofing, the machine accepts pre-profiled trapezoidal or corrugated sheets up to 1250 mm width and 0.3 mm to 0.8 mm thickness. Utilizing a precision CNC-contoured upper and lower crimping tool set driven by a 5.0 HP heavy hydraulic power pack, the machine introduces sequential micro-crimps at mathematically calibrated pitches to produce smooth, non-kinked circular arcs from a 2-meter radius up to infinity. A centralized Delta/Siemens PLC touchscreen interface allows the operator to input the building span, arch height, sheet length, and desired radius; the automated feed table then automatically steps the sheet through the crimping jaws with micrometer-level step indexing. Engineered with hardened alloy steel dies that prevent paint cracking or zinc coating peeling, this crimper delivers unmatched arch consistency and structural rigidity for heavy commercial roofing fabricators across India and global export markets.

Frequently Asked Questions — Automatic Roofing Sheet Crimping Machine

How does the machine calculate the crimping steps for a specific curved roof radius?

The operator enters the target arc radius or shed span into the PLC touchscreen, which automatically calculates the required step distance and crimp depth.

Does crimping cause paint peeling or micro-cracking on colour-coated PPGI sheets?

No. The Cr12 die contours are mirror-polished and radiused to distribute compressive bending smoothly, preventing micro-fractures in paint or zinc layers.

What sheet widths and profile shapes are compatible with this crimping machine?

It accommodates standard profiled roofing sheets up to 1250 mm width, including trapezoidal box profiles and round-wave corrugated profiles.

What is the tightest curve radius that can be formed?

The machine can form curves down to a tight 2.0-meter radius, extending all the way to gentle architectural arcs.

What is the production rate of curved panels per hour?

Operating at 25 to 35 crimps per minute, a standard 6-meter curved roofing sheet is completed in approximately 2 to 3 minutes.

What warranty and after-sales support are provided?

Gagan Engineering Works provides a 1-year comprehensive warranty, complete tooling spares, and on-site operator commissioning.
