aluminum buildings

[petersonra]

Building steel is considered an acceptable GE. What about buildings contructed from aluminum framing members?

Presumably one would want to bond the aluminum framing members, but it would seem they would not qualify as a GE since they are not steel.

Where does it say in the NEC the metal frame has to be steel?

Re: aluminum buildings

You know, I looked again, and it does not actually say steel where it refers to an acceptable GE. It uses the word metal.

However, take a look at 250.104(C).

Take a look at 250.30(A)(3)(d) and 250.104's title.

250.30 is for SDS, and 250.104 is for bonding requirements. 250.52(A)(2) does not say steel.

Re: aluminum buildings

It appears that this means you CAN use aluminum framing members as a GE but are not required to bond to them.

This seems odd.

I am aware of that.

Do you not find it odd that those sections only refer to steel?

Well, aluminum is only conductive to lightning.
