Tata Nali Sheet Making Machine
Category: Roll Forming & Sheet Metal | Manufactured by Gagan Engineering Works, Khopoli, Maharashtra
The Tata Nali Sheet Making Machine manufactured by Gagan Engineering Works in Khopoli, Maharashtra is an industrial-grade continuous roll forming machine designed specifically to produce the widely used Indian 'Tata Nali' sinusoidal wave corrugated roofing sheets. Engineered to process Galvanized Iron (GI), Pre-Painted Galvanized Iron (PPGI), Galvalume, and Aluminium coils from 0.15 mm to 0.80 mm thickness, the line forms the exact traditional circular wave pitch (76 mm) and wave depth (18 mm). Featuring 16 to 18 progressive forming stations with mirror-polished hard chrome rollers (EN31/Cr12 alloy steel), solid 75 mm 40Cr alloy shafts, and a heavy-duty hydraulic post-cut shear, the machine delivers a continuous output speed of 15 to 20 meters per minute with ±1.0 mm cut accuracy. Ideal for industrial shed roofing, warehouse roofing, poultry sheds, and rural residential construction across India.

Frequently Asked Questions — Tata Nali Sheet Making Machine
What is the price of a Tata Nali sheet making machine in India?
Prices for an industrial Tata Nali roll forming machine typically range between ₹8,50,000 and ₹18,50,000 depending on automation grade (semi-automatic vs fully automatic PLC line), number of forming stations (16 vs 18 stations), and whether an uncoiler/decoiler is included.
What are the exact pitch and wave depth dimensions of the Tata Nali profile?
The standard Tata Nali profile produced by this machine features a 76 mm (3-inch) pitch from crest to crest and an 18 mm wave depth, conforming to Indian Bureau of Indian Standards (BIS) industrial roofing specifications.
What raw material coils can be processed on this Tata Nali machine?
The machine processes Galvanized Iron (GI), Pre-Painted Galvanized Iron (PPGI), Galvalume (Alu-Zinc 550 MPa), and Aluminium coils with thickness ranging from 0.15 mm to 0.80 mm.
How many sheets can this machine produce in an 8-hour shift?
Operating at 15 to 20 meters per minute, an 8-hour production shift yields approximately 7,000 to 9,000 linear meters of finished Tata Nali roofing panels (approx. 15 to 22 metric tons).
How does the machine prevent scratching on colour-coated coils?
All rollers are CNC contour-turned and electroplated with 0.05 mm hard chrome mirror plating. This eliminates friction scuffing and guarantees scratch-free forming on pre-painted and printed stock.
What commissioning support does Gagan Engineering Works provide?
We provide complete foundation layout drawings, on-site mechanical alignment, electrical commissioning, and operator training across all Indian states and overseas export markets with a 1-year comprehensive warranty.
