Rectangular Pipe Weight Formula

RHS — Rectangular Hollow Section Formula

Weight (kg/m) = (2(W + H) – 4t) × t × 0.00785

W = Width (mm), H = Height (mm), t = Wall Thickness (mm)
Perimeter of hollow cross-section × thickness × steel density constant

Worked Example — 100×50×4mm RHS


              W=100mm, H=50mm, t=4mm

              Weight = (2(100+50) – 4×4) × 4 × 0.00785

              = (300 – 16) × 4 × 0.00785

              = 284 × 4 × 0.00785 = 8.92 kg/m

RHS Pipe — FAQs

What is RHS pipe?▼

RHS stands for Rectangular Hollow Section. It is a hollow structural steel section with a rectangular cross-section profile. RHS tubes are used extensively in structural, fabrication, and architectural applications.

How do I calculate rectangular pipe weight?▼

Use: Weight (kg/m) = (2(W+H) – 4t) × t × 0.00785. Where W = width, H = height, t = wall thickness (all in mm). Multiply by length in meters for total weight.

What is the weight of a 100×50×3mm rectangular pipe?▼

A 100×50×3mm RHS pipe weighs approximately 6.79 kg/m. For a standard 6m length, total weight is approximately 40.7 kg.
