Ask an experienced slitting line operator what causes most recoiling problems, and the answer is often a single word: tension. Loose wraps, telescoped coils, strips that wander on the recoiler, edge damage and even surface marks can usually be traced back to how tension was created and controlled between the slitter head and the recoiler....
When a new slitting line is commissioned, most of the attention goes to the machine: the decoiler, the slitter head, the recoiler and the controls. Yet the parts that actually touch and separate the metal are the knives, spacers and stripper rings mounted on the arbors. If the tooling package is undersized, poorly matched to...
When Indian processors plan a new slitting line, one question comes up early: buy from an Indian manufacturer, or import a line from abroad, most often from China, Europe or Taiwan? Imported lines are sometimes quoted at attractive prices, while Indian manufacturers offer proximity and local support. The right answer depends on your material, budget...
Aluminium is one of the fastest-growing metals in Indian manufacturing. Electric vehicles use it for battery enclosures and lightweight body parts, the electrical sector uses it for transformer windings and busbars, and packaging, building facades, HVAC fins, cookware and appliances all rely on aluminium strip. Much of that strip begins as a wide coil that...
A slitting line can run reliably for 20 years or more, but only if it is maintained properly. Most of the problems processors face, from burr and camber to loose coils and unplanned breakdowns, can be traced back to maintenance that was skipped or done inconsistently. This slitting line maintenance checklist breaks the work into...
Since 1 January 2026, the European Union’s Carbon Border Adjustment Mechanism (CBAM) has been in its definitive phase. EU importers of iron and steel now have to account for, and pay for, the carbon emissions embedded in what they buy. For Indian steel exporters, this has turned carbon from a reporting exercise into a commercial...
Infrastructure, railways, construction equipment, pre-engineered buildings, shipbuilding and heavy fabrication all consume large volumes of hot rolled sheets and plates. Much of that material starts life as a hot rolled coil and is converted into flat sheets on an HR cut to length line. With government capex continuing to drive steel-intensive sectors, many processors are...
India’s solar build-out has created a large and steady market for solar module mounting structures. Utility-scale parks, rooftop systems, carports and agricultural solar installations all need purlins, rafters, columns, bracings and clamps, and most of them are made from galvanised steel. For fabricators and coil processors, that demand starts at the slitting line. Roll formers...
Electric vehicles, energy-efficient industrial motors, fans, pumps, compressors and transformers all have one thing in common: they depend on electrical steel. As India pushes electric mobility, higher motor efficiency classes and a much larger power grid, demand for precisely slit electrical steel is growing quickly. Electrical steel is also one of the most demanding materials...
India remains one of the fastest-growing steel markets in the world. India Ratings and Research expects domestic steel demand to grow at a high single-digit rate in FY27, after 7.4% growth in FY26. Safeguard duties on flat steel imports, set at 11.5% for April 2026 to April 2027, have also supported domestic prices and encouraged...
