Accepted Answer

Black channel (as-rolled) has no protective coating and is suitable for indoor, dry environments or where further painting will be applied.

How do you calculate the theoretical weight of a steel channel?

Accepted Answer

Weight equals cross-sectional area times length times steel density 7.85 grams per cubic centimeter. For example, 100 by 48 by 5.3 millimeter channel weighs about 10 kilograms per meter. We offer a full weight chart for all standard sizes, and actual weight may differ slightly within tolerance.
