Aluminium Deformed Bar

No.

Not aluminum but basalt and frp hollow type...

Any coupler for rebar?

do you need rebar coupler? if you want ,we could supply, high quality and price competitive. lola***

Yes. I've dropped a heavy object onto aluminum bar, and boy, did it deform it.

All joking aside, why? If you are referring to rebar aluminum would be a lousy choice in concrete- a friend of mine just did a job that required stainless steel rebar.

Yes. I tripped over a load and bent them only last week.

Youngken,

What are you looking for?

A lightweight rebar or just Aluminum rebar profile.

What's your mission soldier?

A light weight rebar which can be used with coupler (can be threaded), most probably aluminium rebar

I think there would be issues with corrosion between the aluminum and concrete. Are you looking for a lightweight reinforcing solution? Look at the Basslt rebar or look at some type of tubing. How much do you need?

I don't see the logic of wanting a lightweight (as in Aluminum) reinforcing bar in a concrete structural element when the bar weight is such a tiny percentage of the total weight.

Also, aluminum reacts terribly with alkaline concrete.

Additionally, aluminum doesn't not exhibit the same ductility as steel rebar, hence you will most likely encounter a catastrophic failure (with no advanced warning like you would with steel reinforcement) of a concrete structural element.

Agreed!!!

One advantage is installation in difficult to access geographic areas.

One big disadvantage compared to steel is the lack of bending capacity. So straight bars only ?
