PRODUCT DETAILS

Description

Rectangular tubes are formed from coils and then ran through a series of dies. They are are welded from the inside to form their shape. Rectangular tubes are generally used for maintenance and structural purposes.

For mechanical and structural applications, rectangular hollow sections (RHS) are popular. This is because the flat surface makes it a more economical structural solution for joining and different types of manufacturing work. For soldering or joining, RHS requires minimal edge preparation. Because of the rectangular shape of this type of hollow section, parts only need to be cut straight when joining to other flat surfaces.

Dimensional Tolerances

Dimensional Tolerances
Outside Diameter:		Twist:	Maximum twist per 3 feet of length
Largest outside dimension	Outside tolerance including convexity and concavity	Longest outside dimension
up to 2 1/2"	±.020"	2" to 2 1/2"inclusive	.062"
over 21/2" to 31/2" inclusive	±.025"	over 21/2" to 4" inclusive	.075"
over 31/2" to 51/2" inclusive	±.030"	over 4" to 6" inclusive	.087"
over 51/2"	±1%	over 6" to 8" inclusive	100"
Tolerances include allowance for convexity or concavity. For rectangular sections, the tolerance calculated for the larger flat dimension shall also apply to the smaller flat dimension. This tolerance may be increased 50 percent when applied to the smaller dimension, if the ratio of cross sectional dimension is between 1.5 and 3, and 100 percent when the ratio exceeds 3.		over 8"	112"
		Straightness: Permissable variation shall be 1/8" times the number of feet of total length divided by 5:
		.125" x (total length) ÷ 5
Wall Thickness:		Squareness of Sides:
Maximum allowable variation	±10%	Adjacent sides may deviate from 90° by a tolerance of plus or minus 2 degrees maximum.
(wall thickness is to be measured at the center of the flat, exclusive of the weld area, and not at the corners)
Worner Radii:		Flash:
The radius of any outside corner shal not exceed three times the specified wall thickness		Structural tubing usually is supplied flash-in. The height of the flash will vary with the wall thickness of the tube.
