How to use the Window & Door Grill Steel Weight Calculator

Grill fabricators usually quote per square foot, but smart buyers check the steel weight behind the quote — it is the best way to compare two workshops fairly. This window grill steel weight calculator estimates the mild-steel weight of your windows and doors from their total area and the design density: light designs run about 3.5 kg per sq ft, medium 5 kg and heavy jali patterns 7 kg. Add up all your openings, pick the design, and you know the steel tonnage before the first bar is cut.

  1. Measure each window and door opening and add the areas into the Total grill area field.
  2. Select the grill design density — light, medium or heavy jali.
  3. Click Calculate to see the total steel weight in kilograms.
  4. Use the weight to cross-check the fabricator quote per square foot.

Formula

Steel (kg) = total grill area (sq ft) × design rate (3.5 light, 5 medium, 7 heavy kg per sq ft). Add 5% for cutting wastage on intricate designs.

Worked example

Ten windows of 5 sq ft each give 50 sq ft of grill. With a medium design at 5 kg per sq ft, the steel needed is 250 kg — about a quarter tonne of MS bar to arrange with the fabricator.

Frequently asked questions

Roughly 3.5 kg for light, 5 kg for medium and 7 kg per sq ft for heavy jali designs in MS square bar.
