So I found some tubing. I know nothing about it other than its heavy as hell and its pretty long. I wanted to know if it would work good for making a rear bumper? I have some pictures of measurements I got. I don't know much about it but I can figure out how to make a rear bumper

 

check out "INT3RC3PTOR"s truck. he has a pretty sick rear bumper and u could make one with what you have.

 

yeah his is square tubing and I wanted to have mine come out a little more like this:



I'd like the bumper to not be sucked into the truck but have it stick out and cover the lower bed sides.

 

i would say go for that same design. i like how the receiver is built right into the middle.

 

I agree, I like that design a lot too. Nice and simple

 

yeah, getting a welder next week so loks like I'll try doing it some time then.

 

Yeah that design you have pictured is nice and simple and looks good. I wouldn't mine making one for my truck. Just need a welder!

 

it looks galvanized. if you even THINK of welding that, you better wear a respirator and do it outside on a windy day. galvanized steel is BAAAAAD stuff...

 

ok, well I'm going to be welding it none the less but I'll keep that in mind thanks.

 

You can get arsenic poisoning from inhaling that stuff while welding right?

 

probably, but I'm really not to worried about it right now. I'll wear a mask if that makes everyone feel better. I'll let you all know how it goes.

 

yea bro. keep us posted. i was thinking of making me a pre-runner bumper for the front and mount some hella's up on it.

do i smell another idea....?

 

welding galvi can mess you up pretty bad

 

well, we'll see. The weather doesn't look that great for next week but I'm going to see what I can do. I'm suppose to be welding up some stuff on my brothers frame (87 YJ 2.5L 5 speed putting a 4" lift on it) because its kind of rotted out.

 

Make sure you grind the coating off where you weld it. You wont get a good weld if you dont, it will look like crap and have this white residue all over it.

 

oh yeah, I always grind where I'm welding. Defiantly.

 

If you decide to, give me a call. me and my buddies can do some killer tube work for you for a really good price...

 

do what you want, but when you are f*cked up cause of a stupid bumper when you could have bought better steel for 30 bucks (probably less), tell your family that you were warned that it was a stupid fawkin idea.

kthxbye!

 

yeah i dont know that you should be using that tube... id try to find something else.

I know for around 100 bucks i got 90 feet of CREW 1.75" .120 wall tube.

 

give this place a call and see how much they want for CREW .120 wall

1-3/4 .120 HREW is 2 bucks a foot here without even looking. thats stupid cheap and like beard said, you buy in bulk it gets cheaper per foot with the quantity.

its absolutely moronic to even think of taking a chance...

 

Hrew dude...

 

which is stronger?

Cold Rolled Electric Welded?

or

Hot Rolled Electric Welded?

I always thought cold rolled was.

 

maybe a bit, but as far as I know, its not nearly as readily available. Ive never seen it :shrug...

 

weird its all the place i go has. besides DOM

check this

Cold Rolled Electric Welded (CREW)
Cold rolled steels are steels that are shaped by high pressure rollers at normal temperature in the steel mill. Cold rolling work hardens the material substantially. The steel is then welded by the electric weld process. A cold rolled steel can be either a mild steel or a high carbon steel. Can also be termed as ERW (Electric Resistance Welded). See » ERW

Hot Rolled Electric Welded (HREW)
Hot rolled steel is steel that is rolled to size in the mill while red hot. Hot rolling steel does not work harden it as much as cold rolling. For this reason, hot rolled steel is more easily machined than cold rolled.

Electric Resistance Welded (ERW)
Cold formed, electric resistance welded tubing can be produced in round, square or rectangle shapes. ERW tube is produced by processing a flat rolled steel into strips which are cold-formed, welded and seam annealed or normalized (depending on the manufacturer). You can usually identify ERW tube by the blue strip down one side of the tube (which is the welded area). The ERW process can guarantee the weld to be as strong or stronger than the rest of the tube body. The origin from a flat strip results in a more concentric product than Cold Drawn Seamless (CDS). ERW can also be known as CREW (Cold Rolled Electric Welded).
Typical Applications:
Structural columns, beams, supports, heavy equipment frames with 58,000 PSI tensile.
