SS Square Bars FAQ:

What is the size of a SS 304 square bar?

The size of an SS 304 square bar can vary widely depending on the manufacturer and specific application. Common sizes range from small dimensions, like 10mm x 10mm, to larger dimensions, like 100mm x 100mm. For exact sizes, it’s best to check with the supplier or manufacturer.

What is the length of a 12mm square bar?

The length of a 12mm square bar can vary based on the supplier. Typically, square bars come in standard lengths like 1 meter or 3 meters, but custom lengths are also available.

What is the formula for SS bar weight?

Weight (kg) = Volume (m³) × Density (kg/m³)
For a bar, the volume is found by multiplying its length, width, and height (or diameter for round bars). The density of stainless steel is typically about 8000 kg/m³.
