Need Section Propertes of Chinese Steel

[rlewistx]

I'm working to add some catwalk platforms to a steel frame power plant. The steel was designed and manufactured in China shipped over. Most of the steel shapes have Chinese designations. I have found some of them, but can't find quite a few. I need section properties for:
BH550
BH600
BH680
BH1200
HN450

Also, what is the significance of the designation 'BH', 'HN', 'HM',

A URL link to a comprehensive web page giving Chinese section properties would be helpful too.

Thanks for your assistance.

Well, what have you found on line?

If it was already designed, can you goto the EOR as ask them? What do you need the section properties for if designed?

i guess it was designed in China ... 'nuff said.

Can you salvage a piece to test ? measure various sections on the finished ass'y ?

ask the guys who designed it ?

another day in paradise, or is paradise one day closer ?

Thanks for the questions.
I'm doing an addition to the original project. I don't know the EOR for the original project, nor have the ability to contact him.
I'm looking for someone to assist me who has experienced with Chinese steel designations and can give me section properties of the steel beams in questions. I also would like to know why the have different letter designations.

Thanks.

Check this Link for description as well as available sizes of beams designated as HN and HM from one manufacturer.

A good structural engineer is often a blessing for others.
