Basic Knowledge Points of Nanjing Steel Pipe Scaffold Classification

Steel scaffolding is a widely used facility in industries and construction. Owing to its construction from steel pipes, it is named as such. It is precisely due to its material – being hollow in the middle – that it is lightweight and easy to assemble. Let me share a little secret with you – there are both single and double row steel scaffolding available.

Single-rail scaffolding consists of scaffolding with only one row of uprights, with one end of the cross bars resting on the wall. Double-rail scaffolding, on the other hand, is composed of two rows of uprights (inner and outer) and horizontal longitudinal and transverse bars.
　　
Double-deck scaffolding has a slightly wider range of application and is primarily used in projects that require higher bearing capacity. In contrast, single-deck scaffolding serves a different purpose, mainly used for interior wall plastering and painting, etc., which do not require bearing loads.

Advantages of Steel Pipe Scaffoldings:
　　
Steel tube scaffolding is economical and easy to process. By increasing the utilization rate of steel tubes, better cost-effectiveness can be achieved in material usage. The equivalent steel consumption per square meter of construction for coupling steel tube scaffolding is approximately 15 kilograms. It has a high bearing capacity. When the geometric dimensions and structure of the scaffolding meet the relevant requirements of the standards, the bearing capacity of a single steel tube column in steel tube scaffolding can reach up to 15kN, 35kN (1.5tf, 3.5tf design values). Steel tube scaffolding is versatile in construction. Due to the ease of adjusting the length of steel tubes, it is easy to assemble and dismantle. The simple coupling connections make it adaptable to scaffolding for various flat and vertical buildings and structures.

The disadvantages of steel pipe scaffolding:
　　
The connection quality at the fastener nodes is significantly affected by the quality of the fasteners themselves and the worker's operation. Fasteners, especially bolts, are prone to loss; they transfer loads and internal forces by frictional resistance; the rods at the node are eccentrically connected. This consequently reduces their load-bearing capacity.
