View Full Version : steel gauge thickness?

05-27-2006, 03:54 PM
I have a quick question about mower frame durability. I understand the differences in measuring steel thickness in gauge format. 7 gauge, 10 gauge, etc... If a frame thickness is 3mm how does this relate in regards to gauge thickness? Makes a difference because i need a durable frame and John Deere only list there frames as 3mm and i do not how to interpet this. Any help would be aprreciated.

here's a nice chart, however it's all in SAE. http://www.unc.edu/~rowlett/units/scales/sheetmetal.html

But converting metric to SAE is pretty easy...http://www.sciencemadesimple.com/length_conversion.php

Answer: 3mm is equal to .12 inches, which appears to be roughly 11 gague according to the chart.

yup 11ga is 3mm or .115-.119

I think Scag is about 7 ga and have reinforcement panels that are 10 - 11ga. I would guess they are just about the strongest?
