Stainless angle is the corner and frame stock for railings, food and pharma equipment, and exterior work that has to survive weather. 304 is 0.289 lb/in³. A 2×2×1/4 equal-leg angle is 3.25 lb/ft. A 4×4×3/8 is 9.92 lb/ft. 316 is the same weight. Enter the leg size and thickness below.
Quick answer
Calculate 304 and 316 equal-leg stainless angle weight by leg size and thickness.
Common 304 stainless angle weights
Equal-leg angle cross-section = thickness × (2 × leg − thickness). Weight = that area × length × 0.289. Values use nominal dimensions and match the calculator above. 304 and 316 weigh the same for quoting.
Questions welders ask about this one
How much does 2×2×1/4 stainless angle weigh?
About 3.25 lb per foot in 304. Math: 0.25 × (2 × 2 − 0.25) × 12 × 0.289 = 3.25 lb/ft. 316 is the same weight.
Does 304 and 316 stainless angle weigh the same?
Yes for any practical quoting. 304 is 7.93 g/cm³ and 316 is 7.98 — about 0.6% apart, both rounding to 0.289 lb/in³. 316 costs more for its added molybdenum and corrosion resistance, not for any weight difference.
Why is angle weight not just two flat legs added up?
The two legs share the heel corner. Adding two full legs double-counts it, so the area formula is thickness × (2 × leg − thickness), which removes the overlap once. On heavy stainless angle that correction is real money.
Weight is only half of material cost. To turn these pounds into a number you can quote, run the weld cost calculator for wire, gas, and labor per inch, or the job pricing calculator to build the whole bid.
