I'm looking at steel online and I have to select one of these for the grade of 1 - 1 1/2 square tube I'm using in my build.  Whats the grade of steel I need? Standard stuff please. Thanks,

not one of them, square tube will either be 1010, or 1020...

Cant you source any locally, square tube is generally easy to find, should be cake in your area...

I'm going through metal supermarket and the web site is asking me to verify what I need so they can make sure they have it in stock. Thanks for the quick answers!

You want the 4130!!! thats chomolly! But expensive!

All the other #s have a higher carbon grade and are not as good for welding. Regular mild steel has the last 2 numbers as lower numbers like 1018, 1117, 1215 and so on. Stay below 30 for the last 2 numbers

[Doug Heim]

Yeah bug is right. Square tube is really easy to come by and mild grades are cheap. I dont even think you can get square in 4130! Can you?

Oh and Metal supermarkets is Expensive IMO. How much you need and where you at? Ill pre cut it if you know the length's and send you some at my cost. I get material at Machine shop price. But shipping that may suck. Just so you know the offer is there. I am always glad to help out a fellow buggy enthusiast!
