How much steel (TMT bars) is required for a 1000 sq ft house?

⚡ Quick Answer
A 1,000 sq ft RCC frame house requires 3.5 to 4.5 metric tonnes (MT) of TMT steel bars. This translates to roughly 3.5–4.5 kg of steel per sq ft of built-up area.
TMT Steel Requirement by RCC Member
| RCC Member | Steel Required | Common Bar Sizes |
|---|---|---|
| Columns | 0.8–1.2 MT | 12mm, 16mm main bars + 8mm stirrups |
| Beams | 0.7–1.0 MT | 12mm, 16mm main bars + 8mm stirrups |
| Roof Slab | 1.2–1.5 MT | 8mm, 10mm both ways |
| Foundation (footings) | 0.5–0.8 MT | 12mm, 16mm bars |
| Staircase (if any) | 0.2–0.3 MT | 10mm, 12mm bars |
| Total | 3.5–4.5 MT | — |
Quick Formula
Rule of thumb: 3.5–4.5 kg TMT steel per sq ft. For 1,000 sq ft = 3,500–4,500 kg (3.5–4.5 MT). Seismic zones (Delhi, Northeast) require 10–15% more steel.

Grade Tip
Use Fe500D TMT bars for all structural members — the "D" indicates ductile grade, mandatory in seismic zones III, IV, V. Brands: TATA Tiscon, JSW Neosteel, Kamdhenu, SAIL.
