Gate & Railing Steel Calculator Nepal
Estimate mild-steel lineal metres, weight (kg), and material cost for house gates and boundary or balcony railings.
Gate leafs
Railing run (optional)
Gate 20.8 m · railing 85.0 m lineal after waste. Add hardware, paint, and post foundations separately.
How this works
gate lineal = leafs × (perimeter + mid members) × (1+waste)
posts = ceil(run / spacing) + 1
rail lineal = posts×H + rails×run + balusters×H × (1+waste)
weight kg = total lineal × kg/m
cost = weight × NPR/kgWorked example
Double gate 2 × 1.5 m × 1.8 m with simple frame at 3 kg/m and 5% waste:
- Perimeter lineal ≈ 13.2 m → ~13.9 m with waste
- Weight ≈ 41.6 kg before railing extras

FAQ
How do I estimate steel for a house gate in Nepal?
Break the gate into leaf width and height, count horizontal and vertical members, convert total lineal metres of section to kilograms using the section’s kg/m from a steel table, then multiply by today’s steel rate. This calculator does that for single or double leafs and can add a railing run for boundary walls and balconies.
What kg/m should I use for mild steel sections?
Use the manufacturer or IS section table for your exact hollow section, angle, or flat. As a rough planning range, light gate frames may land around 2–4 kg per metre of member; heavier designs use more. The calculator multiplies total lineal by your entered kg/m — update it when the section changes.
Does this include hinges, locks, paint, and concrete for posts?
No. It estimates primary steel lineal weight and optional steel cost. Gate hardware, welding consumables, primer/paint, foundation concrete for posts, and decorative cast elements are separate. Pair boundary masonry with the boundary wall calculator.
How are railing posts counted?
Posts = ceil(run length / post spacing) + 1 to close the far end. Horizontal rails run the full length; balusters are counted per metre of run times railing height for lineal. Adjust spacing for codes and wind on exposed sites.
Is the result structural design?
No. It is a material takeoff for budgeting and ordering. Gate posts, vehicle loads, and balcony railings that protect a fall need engineering or standard details from your designer — especially in seismic zones.
