But the biggest weakness of the frame scaffolding is poor security, low construction efficiency, material consumption, consumption of high production cost. Production material of frame scaffolding steel pipe is common across the country, and steel products is larger, the frame scaffolding steel tube, about 10 million tons, but the inferior, extended use and unqualified steel pipe accounted for more than 80%, about 10 to 1.2 billion total fasteners, of which about 90% for nonconforming, such enormous quantity wide unqualified steel pipe and fasteners, has become a construction safety problems.
