The A36 carbon steel rectangular tubing has been hot rolled and meets American Society for Testing and Materials International ASTM A36 specifications. The A36 carbon steel grade is a structural steel that has better formability than 1018 carbon steel. The tubing has been hot rolled, a method of compressing metal between two rollers at a temperature above the material’s recrystallization temperature to attain the specified dimensions.
Steel is an iron alloy with carbon and other elements that modify the steel to achieve specific properties. In general, steels with higher carbon content have greater strength, hardness, and wear resistance, while those with lower carbon content have more formability, weldability, and toughness. Carbon steels, which include most AISI-SAE grades in the 1000 range, are classified by their level of carbon content as low (below 0.3%), medium (0.3% to 0.6%) and high (0.6% and above). Alloy steels, which include AISI-SAE grades in the 1300 and 4000 ranges and above, incorporate elements such as chromium, molybdenum, and nickel to modify properties like machinability and corrosion resistance. Tool steels, which include most grades with a letter and number grade designation, have high carbide content for wear resistance, high hardness, and the ability to hold a cutting edge. Some tool steels are designed to resist deformation when used in elevated temperatures.
Tensile strength, used to indicate a material’s overall strength, is the peak stress it can withstand before it breaks. Wear resistance indicates the ability to prevent surface damage caused by contact with other surfaces. Toughness describes the material's ability to absorb energy before breaking, while hardness (commonly measured as indentation hardness) describes its resistance to permanent surface deformation. Formability indicates how easily the material can be permanently shaped. Machinability describes how easily it can be cut, shaped, finished, or otherwise machined, while weldability characterizes the ability to be welded.

This piece of metal is thick and heavy (obviously). It measures exactly 2" x 3", 0.12" Wall, 24" Length (by comparison / unlike a piece of wood 2 x 4 which is actually 1.5 x 3.5).
So what else to say. It is again the exact dimensions specified. It is thick and heavy. It is straight, mine arrived in perfect condition and was a reasonable price. It shipped for free because I met the $49 threshold minimum for free shipping.
If you need a square metal tube which is exactly 2" x 3", 0.12" Wall, 24" Length, look no further.
I do not know if this will be deleted or if my review wont get published BUT CHECK YOUR BANK ACCOUNT because I was charged TWICE for this and only order it one time. The (lengthy) process of the initial phone call, put on hold, etc now 7-10 business days for a refund sucks.
Worst customer service EVER by Amazon - still my favorite retailer however I guess it is true that everyone makes mistakes.
got my refund from Amazon
Id HIGHLY RECOMMEND finding a local dealer of metal because near me (Schorr Metals Placentia) this (these) pieces of tubing are about 1/5th the price... $0.59 per pound
way less money, Id say at most 3 x 2 x 24 would be $3 to $4 dollars
Measurements of the 2x4 .120 wall piece I ordered were spot on and it arrived on time as expected.
It's a big steel tube.
It's cheaper than at my local hardware, and faster shipping.
Regularly formed, no twists, bends, burrs, or other deformities.
I don't have more of it?
I bought 72" and 36" lengths, sliced them up with a cut-off wheel on an angle grinder, and made a solid bumper mount for my 88' Dakota. The OEM front bumper mounts aren't easily found anymore (unless you go to the dealer or find NOS, both of which cost more than this and aren't as strong) and the local junk yard parts were all horribly rusty or bent. It's not standard equipment, but it gets the job done.
It was the perfect size for my need. I cut it in half, welded the two pieces together and after drilling a few holes, had a rock-solid winch mount for my tractor.
As expected, which is not always the case the the risky world of mail-order, it is rectangular tube is 2" x 1" OUTSIDE diameter, of 1/16"-thick steel. I ordered the 12 incher, and it is actually 12 1/4" long.
Industrial-looking and unfinished, as in its photo. Mine has a visible welded seam. It doesn't look like it would disappoint in any project.
This review seems superfluous, if you trust the photo & description, so it's written just to say that you _can_ trust the photo & description.
