Thickness Tolerance:Generally, the thickness should not deviate more than ±3% from the specified nominal thickness.
Length Tolerance:
The length tolerance for hot-rolled angles is typically ±1/8 inch for lengths under 20 feet, and ±1/4 inch for lengths over 20 feet.
Width Tolerance:
Width tolerances may vary, but it's common to see tolerances of ±1/16 inch.
Leg Length Tolerance:
For the leg lengths of the angles, tolerances are generally within ±1/8 inch.
Straightness:
The allowable deviation from a straight line (usually over a length of 10 feet) is typically around 1/4 inch.
Twist:
The allowable twist in a steel angle is often specified as a maximum of 1/8 inch per foot of length.
Camber:
The allowable camber or bend in a hot-rolled steel angle is often specified and can vary depending on the application, but it is generally limited to a certain amount (not exceeding 1/8 inch per 10 feet).
