key word : Seamless Steel Pipe

Description

Square tube is formed from coil and then ran through a series of dies. It’s welded from the inside to form its shape. Square tubes are generally used for maintenance and structural purposes.

Some examples of square tubing applications would be building construction, railings, and sign posts. They are measured by their outside dimensions and their wall thickness.

Square Tube is available in the following metal types:

Alloy Steel

Mild Stee

Carbon Steel

Stainless Steel

Square tube has similar uses to RHS and is used for both industrial and construction applications. Square section RHS is available in the same thicknesses as RHS and dimensions range from 20 mm x 20 mm to 400 mm x 400 mm.

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.
