Question 1

How much steel is required for a slab?

Accepted Answer

A common thumb rule is 3.5-4 kg of TMT steel per square foot for residential slabs, and somewhat more for commercial slabs carrying heavier loads. This is only a rough estimate — actual reinforcement must come from a structural engineer's design based on span and load.

Question 2

Is this steel calculator accurate enough to order materials directly?

Accepted Answer

No — treat it as a starting ballpark for budgeting, not a purchase order. Structural reinforcement depends on span, load, and slab design that only a structural drawing can specify correctly.
