- For
- Steel buyers, fabricators, and construction estimators
- Worth noticing
- It includes formulas for shapes such as hexagonal bar and pipe, and flags that rounded tube corners can make actual weights lower.
Field notes
The reference section supplies shape-specific shortcuts, including 0.02466 × (OD − t) × t for pipe weight per meter. It also gives material densities for carbon steel, 304 and 316 stainless steel, and aluminum. The page cautions that nominal-dimension estimates omit rolling tolerances, rounded box-section corners, and cutting loss.
