Product Description

The A36 carbon steel square 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.

Good price, very fast shipping. I got this metal tube faster than if I waited for the weekend to browse the home center or rummage the scrap yard.

The rectangular tube I purchased was as described on this page: 0.625 x 0.065 x 12 inches.

The tube may have pieces of trim or shavings inside. Be careful. The item was shipped in a thick cardboard tube that weighs as much as the metal.

It's nice and sturdy to be used for an outdoor lamp extension.

I was about to buy this (I needed 40 feet for a welding project), and I had the clever idea to Google local metal & welding supply. I'm so glad I did. I found the same hot rolled 1x1x0.12 (14gauge) A36 locally for $1.10 a foot (plus sales tax) and they helpfully cut it down to the length of my truck bed at no charge. Amazon's certainly got a better selection and better pricing than you'll find in home improvement stores, and they deliver to your door--and for that convenience you pay over 4 times as much.

Amazon never ceases to amaze me with what they have available.

I am always building something, and need different types of metal.

Locally metal is priced ridiculously, and online the shipping just kills you.

Now I can get different lengths and shapes of steel, aluminum, etc. shipped for free (and quick!) with my Amazon Prime membership.

No more 20 mile trips to the metal yard to pay top dollar.

Awesome!

If you want to make your own 2 inch square tube hitch of some type this 12 inch piece will work well. I would recomend a good coating of a Por15 or equivalent to be able to take the outside envronment if you are going to leave it in place on your vehicle, otherwisw just a coat of rustoleum primer and topcoat will be fine.

Shipped immediately, great quality. only thing is to be careful with the cut ends as they have a few metals spurs. Wear gloves!

Wall Thickness: 0.065Overall Width: 2Number of Items: 1Overall Length: 36Thickness: 2 Verified Purchase
Bought a 2" x 2" x .065" piece to convert my roof mount bike racks to hitch mount. I was debating about getting the .065" or the .12" wall thickness. While the thicker tubing may be stronger, it's also double the weight. I am very glad I got the .065" wall thickness. It is very strong and can support my full body weight (200lb) jumping at the end of a 3ft piece mounted to the hitch without flexing at all - so it will easily support a couple 20lb bikes. It's a little dirty when it arrives so be careful if you're wearing nice clothes when handling it.

A recent project required some 3/4" square tubing to slide over some existing square tubing. None of the local home improvement stores showed stock. A quick check of Amazon Prime showed they now have this available, in just about any size. I had it in two days in a super heavy duty cardboard tube, well packed and measured true.
