The JSEP HI-RIB machine produces trapezoidal profile roofing sheets from Colour Coated PPGL and Bare Galvalume coils at 25–30 meters per minute, with EN-31 hardened rollers, a fully automated PLC control system, and cutting accuracy of ±2mm.
A Roofing Sheet Roll Forming Machine is a specialized industrial equipment that continuously shapes flat metal coils into profiled roofing sheets through a series of precision-engineered roller stations. As the metal coil passes through each forming station, the rollers progressively bend it into the desired cross-sectional profile such as trapezoidal (HI-RIB), corrugated, tile, or standing seam at high speed with zero manual intervention.

The HI-RIB profile also called the Trapezoidal profile, T-Rib, or High-Rib is the single most widely manufactured and installed metal roofing sheet profile in India and across the developing world. It is the dominant choice for industrial and commercial construction for one core reason: its high, flat-topped trapezoidal ribs deliver superior structural strength, excellent water drainage, and exceptional spanning capacity.
The HI-RIB profile’s 65% market dominance in Indian metal roofing makes the JSEP HI-RIB Roll Forming Machine the highest-ROI machine investment for any roofing sheet business entering or expanding in India.

PEB Warehouses & Logistics Parks: The #1 application. India’s warehouse boom driven by e-commerce (Amazon, Flipkart), 3PL logistics, and the National Logistics Policy has created explosive demand for HI-RIB roofing sheets. PEB warehouses of 50,000 sq. ft. to 5 lakh sq. ft. use trapezoidal profile sheets exclusively for their speed of installation and structural efficiency.
Steel & Metal Plant Sheds: Clients including JSW Steel, Vedanta Aluminium, Hindalco, and Bhushan Steel use HI-RIB sheets for their processing plant roofing and cladding. These projects require the high-tensile 550 MPa capability of the JSEP machine for processing thicker gauge coils.
Agricultural Sheds & Poultry Farms: India’s growing agribusiness sector requires millions of square meters of roofing sheets annually for poultry farms, dairy sheds, grain storage, and irrigation infrastructure. PPGI-coated HI-RIB sheets are the standard specification.
Railway Stations & Metro Canopies: Indian Railways and urban metro authorities use trapezoidal profile sheets for station canopy structures. The profile’s long spanning ability eliminates intermediate supports, keeping station platforms open and unobstructed.
Affordable Housing (PMAY): The Pradhan Mantri Awas Yojana scheme drives rural housing construction using galvanized HI-RIB roofing sheets as the standard roofing specification for pucca houses under government allocation.
Solar Rooftop Mounting: The trapezoidal rib structure provides a perfect base for solar panel mounting systems. Solar mounting clamps attach directly to the ribs no drilling required making HI-RIB sheets the preferred base for India’s solar rooftop programme.
Export Markets: JSEP HI-RIB machines are operating in roofing sheet manufacturing plants in UAE, Saudi Arabia, Nigeria, Kenya, Tanzania, Bangladesh, Nepal, and Sri Lanka. International buyers prefer the JSEP machine for its heavy-duty construction, long service life, and Pan-India spare parts availability.






The complete roofing sheet roll forming machine line consists of five core components working in sequence:
1. Hydraulic De-Coiler — Holds and feeds the steel coil into the line at controlled tension
2. Feeding Guide & Straightener — Ensures the coil strip enters the forming stations perfectly flat and centred
3. Roll Forming Unit — The heart of the machine. Multiple forming stations (24-26 for HI-RIB) progressively shape the flat strip into the finished trapezoidal profile
4. Hydraulic Cutting Unit — An HCHCR-bladed shear cuts the formed sheet to your exact programmed length automatically
5. PLC Control Panel + HMI — The brain. Operators set sheet length, batch quantity, and production speed on a touchscreen. The machine handles everything from there
1. Colour Coated PPGL (Pre-Painted Galvalume) The premium choice for modern industrial and commercial roofing. PPGL uses an aluminium-zinc (AZ) alloy base typically AZ70 or AZ150 for 3–4x better corrosion resistance than standard GI. The JSEP machine’s chrome-ground EN-31 rollers handle PPGL without scratching or lifting the colour coating. Common thicknesses: 0.35mm to 0.60mm. Used by: PEB contractors, warehousing projects, export-quality sheet manufacturers.
2. Colour Coated PPGI (Pre-Painted Galvanized Iron) The most widely used material in the Indian domestic market. PPGI provides an excellent balance of affordability and durability. Suitable thicknesses: 0.35mm to 0.70mm. Used by: Agricultural shed manufacturers, rural housing projects, budget commercial construction.
3. Bare Galvalume (BGL / AZ150) Preferred for industrial roofing where both corrosion resistance and heat reflectivity matter. BGL’s bright metallic finish reflects radiant heat, keeping building interiors cooler. Common thicknesses: 0.40mm to 0.80mm. Used by: Steel plant sheds, cement plant roofing, export to Middle East and Africa.
4. Plain Galvanized (GP Coil) The workhorse of industrial shed roofing in India. Cost-effective, widely available, and easy to process. Thicknesses: 0.40mm to 0.80mm. Used by: Agricultural sheds, low-cost industrial shed roofing, site offices.
