I am looking for same equivalent material spec............if you already got information, can you share?
China is, or used to be (the current material may be some made made material) china on power lines. The separators were made of china to insulate them.
Q235 is a kind of material which is mostly used in China and for the pipes and tubes. It seems that this material has a good quality for this purpose
yes q235b is an europen model and ss400 for china...means Q235B = SS400 = SAE 1045
I wouldn't say that Civil Engineering is developing very slow but the main reason why we are not progressing as fast as other Engineering professions is that our work are directly responsible for the safety of the users. For a country to accept a new concept of design or a new material for construction they want to have severe testing to be carried out to be sure that the new design method won't fail and or the new material behaves as said and that the standard deviation of the material is small enough, these testings take a very long time I know of a Professor doing tests on concrete behavior for the last 5 years and the tests are still going on. So if a new material is developed testing on that material may take years to complete so we are a several years behind but that is because of high safety standards. *Hope this is said correct sorry for the poor grammar its not my strong point :) -Just as an example in South Africa we have a high quality steel and for more economical construction they wanted to import steel from China but when the steel arrived the properties of the steel was so much weaker than the current steel in SA and there standard deviation was so high that they have sent back the steel to China
for 2013, it was China, for 2012, it was China, for 2011, it was Finland, & for 2010, it was China.

China National Building Material Company's population is 40,000.
China National Building Material Company was created in 1984.
According to a USAToday article, in 2005 the number of Americans living in China was 110,000.
It cannot be recycled into new china products, but waste material such as broken china and other ceramics can be ground down to fine particles and used as a bulk filler material in concrete for example.
