American Box section info
American Box section info
(OP)
Hello all,
I have been hunting the net for American box section data. We have to design a frame for manufacture in the US, and I want to make it out of readily available material.
Can someone guide me to the right info? Or maybe send me the data?
Thanks in advance to you all
Mark.

I should have been more clear, I require steel box section. I require details on the corner radius, mass per foot also the second moment of area ect.
Sim to our BS/EN10210-2:1997. I have it in an excel doc.
But I require US standards.
If anyone can help,
Cheers
Mark

You will have to purchase the standard to obtain the information. Very little in life is free...

this is what my old E.M. Jorgensen stock list has to say on the subject:
wall thickness tol is +/-10%
outside dim tol:
(largest outside dimension)
2-1/2" and under +/- 0.020
over 2-1/2 to 3-1/2" +/- 0.025
over 3-1/2 to 5-1/2" +/- 0.030
Over 5-1/2" +/- 1%
squareness of sides can deviate from 90 degrees by +/- 2 degrees

ASTM A501 is 58KSI UTS and 36 KSI Yeild and 23% elongation
ASTM A500 comes in three grades:
Grade A 45KSI UTS 39 KSI Yeild and 25% elong.
Grade B 58KSI UTS 46 KSI Yeild and 23% Elong.
Grade C (also known as ROPS or Roll Over Protection Systems, tubing. It is used for roll cages and cold temp structures) This material is comparatively new and my EMJ book doesn't cover it, but it is stronger than Grade B and has Charpy requirements for cold temp service. I believe it is roughly similar to ASTM A 574 Gr50 in both strength and chemistry but I could be wrong.
