Welcome to our hss rectangular and square shapes free cad downloads page.
Hss tube steel grades.
Standard strength requirements of the tube help dictate applications for which certain tubing is most appropriate.
Our range includes square tube from 3 4 x 3 4 up to 6 x 6 rectangular tube from 2 x 1 through 8 x 4 and round tube from 840 o d.
A hollow structural section or hss is the same thing as tube steel or ts right.
This is the same minimum yield stress of most steel grades used in structural design which makes it easy to remember.
Here you ll find all rectangular and square shapes described by the aisc steel shapes database v14 1.
Actually i ve been asked this very question so i feel a short explanation may be necessary.
The steel tube institute an organization representing the manufacturers of hollow structural sections initiated the change from tube to hss in 1997 to conform to their designation practices.
Steel tubing or tube steel is what we used to use in the u s.
Available grade listings are.
In the recent past hss was commonly available in mild steel such as a500 grade b.
To describe a closed steel section whether of rectangular square or round shape.

Other steel grades available for hss are a847 weathering steel a1065 large sections up to 50 inch sq made with saw process and recently approved a1085 higher strength tighter tolerances than.
Square steel tube is a welded structural grade tubing that is available in either type a513 or a500 grade b depending on it s size and wall thickness either grade is ideal for all structural applications general fabrication manufacturing and repairs.
And the steel day lecture.
Structural tube is often referred to as hollow structural sections or hss.
Structurally there is no difference.
The maximum yield stress of 70 ksi for a1085 hss will lower the expected yield strength.
For more information on grades see table 2 4 which is reproduced below from the steel construction manual 15th ed.
Up to 6 5 8 o.
Astm a500 13 grade b has a 42 ksi minimum for round and 46 ksi for square and rectangular shapes.
W and all hss shapes are available to view and search by grade.
A709 a913 a992.
And msc s steelwise article are you properly specifying materials.
Thus ts is simply an outdated way to specify hss.
Outside diameter measurements for a500 carbon steel tube must be made at positions at least 2 50 8mm from either end of the tubing.
Steel square tube is widely used in industrial maintenance agricultural implements transportation equipment truck beds trailers frames etc.
Structural tubing especially rectangular sections are commonly used in welded steel frames where members experience loading in multiple directions.
