BOX SECTION WEIGHT CALCULATOR
Enter the profile's A and B dimensions, wall thickness (t) and length to instantly see the mass per metre (kg/m) and the total weight including quantity for square or rectangular box sections. Optionally add the corner radius (r). Ideal for fence panel posts, gate frames and sheet-lattice skeletons.
Calculation Data
Formula Used
m = 7.86 ÷ 1000 × [2 × t × (A + B − 2t) − 0.86 × r²] (kg/m)
A, B: sides (mm), t: wall thickness (mm), r: corner radius (mm). Steel density is taken as 7.86 g/cm³. If r is omitted, sharp corners (r = 0) are assumed.

|---|---|
| 20 × 20 × 1.5 | 0.872 |
| 30 × 30 × 1.5 | 1.344 |
| 40 × 40 × 1.5 | 1.816 |
| 40 × 40 × 2.0 | 2.389 |
| 50 × 50 × 2.0 | 3.018 |
| 60 × 40 × 2.0 | 3.018 |
| 60 × 60 × 2.0 | 3.647 |
| 80 × 80 × 3.0 | 7.263 |
| 100 × 50 × 3.0 | 6.791 |
Production Tolerance
Per EN 10219-2, welded box sections carry a wall-thickness tolerance of ±10 % and a side-length tolerance of ±1 %. A 3 % waste allowance is sufficient when sizing orders.
Coating Options
Konak Tel Çit box sections can be hot-dip galvanised (40–80 µm), electro-galvanised or electrostatic powder coated. Rich coating options directly extend field life.
