Product Features

  • A36 carbon steel is a structural steel that has better formability than 1018 carbon steel
  • Hot rolled to attain the specified dimensions
  • Meets ASTM A36 specifications

Product Description

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.

I can always use some steel as I am a newbie to learn welding, and enjoy more so in reviewing business ethics, and policies etc. Welding as I said is a new adventure for me and a heck of lot more intresting, but I must say that I never would have thought of buying steel online. The deminsions of the pruduct description for the piece I ordered was not disclosed, but still curious. My initial wanting was a 1x2 rectangular steel tubing hopefully about 14 inches in lenght to work with, but I took my chances and recieved a 2x3 in a 12.2in lenght and weighs 3lbs. 10.4 oz. A500 mild steel at 0.12 wall thickness. THE AMAZING PART ! It was shipped and received by me in less than 15 hours. The steel was not deburred after cut so be careful. Packaging was over adequate and almost mis represents the product, but hey, it's probably a general box used for various lengths. Box lenght dimensions 1'x2.2'x2". Package stated actual weight being at 5lbs. Though this must be an rounding method by the shipper. (FedEx) Anyway...-1 star for 2 reasons. #1 no clear deminsions listed and #2 being burrs that may put shipper and/or reciever a lanceration. I am still learning my steel but all in all know what exactly your looking for. Most chose not to experience things the way I do because it can be costly. Paid more than 15 but less than 20 so, I'll be more defined next time around.

Hot Rolled Steel Rectangular Tubing, ASTM A36, 2" x 3", 0.12" Wall, 24" Length

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.

6-27-16 UPDATE
got my refund from Amazon

***ALSO***
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

heads up

Was pleasantly surprised to find that I am able to order small quantities of metal with Prime Shipping for when I don't want by a full 20' stick from the local steel yard.
Measurements of the 2x4 .120 wall piece I ordered were spot on and it arrived on time as expected.

Just what I needed to make 2 6" stand-offs. It sawed fairly easy with my portable band saw but drilling six holes is a nightmare. waiting for a new carbide tipped drill bit (for hard steel) from Amazon. would reorder if needed again.

The good:

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.

The bad:

I don't have more of it?

Other thoughts:

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.

Item arrived quickly and was well packaged. Sawn end cuts were square and pretty clean.
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.

It shipped in a reasonable time in easy packaging with no surprises whatsoever.

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.

I bought this steel tubing to make a handrail for the front porch. I like that I was able to order just what I needed and did not have to place a large order. The metal was delivered in great condition. It worked easily and welded well. I am very happy with the finished project, it should last for many years.
