ASTM A500/A500M Gr.C square tube tolerance

*Tolerances include allowance for convexity or concavity. For rectangular tubing having

aratio of outside large to small flat dimension less than 1.5, and for square tubing, the

tolerance on small flat dimension shall be identical to the large flat dimension tolerance.

For rectangular tubing having a ratio of outside large to small flat dimension in the range

of 1.5 to 3.0 inclusive, the tolerance on small flat dimension shall be 1.5 times the large flat

dimension tolerance.For rectangular tubing having a ratio of outside large to small flat

dimension greater than 3.0, the tolerance on small flat dimension shall be 2.0 times the large flat dimension tolerance.
