Stainless steel work is priced on weight. These are the same formulas we use to quote, published so a customer who understands weight cannot be overcharged — by us or by anyone else.
Steel weight per metre comes from the wall thickness and the outside size, adjusted for the density of the grade you picked.
round: (OD − t) × t × 0.02491 kg/msquare: (side − t) × t × 0.03172 kg/m The outer frame is the perimeter of each leaf. Verticals are counted from your chosen spacing across the width. Horizontals run the full width, once per rail.
verticals = floor(width ÷ spacing) − 1 Cutting leaves offcuts that cannot be used. Eight percent is the honest working figure for gate and railing work — anyone claiming zero wastage is hiding it somewhere else in the price.
Fabricated rate per kg covers material, cutting, welding and basic finishing, and differs by grade. Polish is charged on surface area, installation on weight, and motors are a fixed item. Those rupee rates are not on this page until they are confirmed.
SS 304. Multiply by 0.977 for SS 202, or 1.006 for SS 316. Theoretical weights. Mill tolerance on thickness means actual weight can vary by 2–5%.
