Description

The best square stainless steel pipe source is a metal material widely used in construction, manufacturing, and decoration. It is made of high-quality stainless steel with excellent corrosion resistance and high-temperature resistance so that it can maintain a long service life in harsh environments. Compared with round tubes, square tubes have a more stable structure, are easy to process and connect, and are suitable for a variety of construction and industrial applications.

In the field of construction, RHS is often used for structural support and frame construction. Due to its unique shape, it can effectively disperse the load and enhance the overall stability. In addition, the appearance of square tubes is neat and beautiful, which can add a sense of fashion to modern buildings. Many shopping malls, office buildings and public facilities have begun to use it as the main material to enhance the overall visual effect and performance.

Rectangular tubes are formed from coils and then run through a series of dies. They 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 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. In general, this best Square Stainless Steel Pipe has become an indispensable and important material in modern industry and construction with its superior performance and versatility.

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 outside corner radius must 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.
