An 80 mm channel is not one thing

Same nominal height, different standard, different steel. A DIN UPN 80 has a wider flange and a thicker web than a GOST №8, so every metre of it weighs 22.6% more. Steel is sold by weight, so ordering "80 mm channel" without naming a standard is ordering an unknown.

Give us the designation from the drawing and we source that exact section.

Use the weight for the specified series and size. For the У-series table below, the figures are 50 mm: 4.84, 65 mm: 5.90, 80 mm: 7.05, 100 mm: 8.59 kg/m. Confirm the full designation when comparing a price list.

GOST against UPN, height for height

At every height both standards share, the European section is heavier, with the percentage difference varying by size. Swapping one for the other changes the weight you pay for and the load the member carries.

Weight on the invoice

Theoretical channel mass is the kg/m above times the ordered length. Confirm the billing basis with your quotation. What arrives on the truck can differ within the standard's tolerance, up to ±4% per batch under GOST. If you need settlement on weighed tonnage instead, say so when you order.

Hot-dip galvanising (EN ISO 1461) adds zinc to every surface, around 505 g/m² per side on 3 to 6 mm steel. On a light channel that is several percent more mass than the bare figure, so compare galvanised to galvanised.
