In 2012, the national housing construction area of 5.7 billion square meters, and steel structure building accounts for only about 6% dosage of future steel structure building of housing construction in our country can reach at least 20% by 100 kg/square meters, the average amount of steel in the steel weight of the high-rise steel structure housing is 50 kg/square metre ~ 80 kg/square meters, a year only housing construction steel weight of the steel structure can reach 100 million tons.
By the end of 2008, the national highway 590000 Bridges, steel bridge is less than 1%, while the United States steel bridge (33%), accounted for 41% of Japan’s steel bridge.
Great-leap-forward development of railway construction in our country, most of new high speed railway bridge road, 80% of whom are prestressed concrete Bridges, steel bridge is great potential alternative. Pay attention to and policy support, if the steel weight of the steel bridge can be from the current 2 million tons/year to 3 million tons/year increased to around 10 million tons/year.
