Spec sheets, process articles, standards, and material grades — the working foundation of the Indian steel industry, summarised for engineers, students, and operators. Free to browse. Downloads unlock with an email.
Dimensions, sectional properties, allowable loads, and material grades for every Indian-standard hot-rolled section in five families. All spec sheets conform to IS 808 : 1989 and related standards, cross-linked to applicable IS codes and design references.
Four long-form articles on the processes that turn raw ore into structural steel — written for engineers, with citations.
The complete reference on rolling mills — history, metallurgy, physics, components, processes, products, and standards. The root article of the knowledge base.
Process · HotThermomechanical principles, reheating, descaling, roughing, intermediate and finishing trains, controlled cooling, mill stand configurations, and product types. With citations.
Process · ColdTandem, reversing, and skin-pass mills. 4-high, 6-high, and cluster configurations. CR coils, tinplate, and foil — the downstream side of the industry.
