The material of portal scaffolding is generally galvanized tube, which is made by welding. It is produced by carbon dioxide gas shielded welding, through the process of polishing, welding slag, and painting. The main products of Yuantuo Group include door frames, ladder frames and half frames. Portal scaffolding is widely used. It is commonly used in interior decoration or simple exterior wall construction. It can also be used to arrange a full house as a support frame. It can also be equipped with universal wheels, so that it can move quickly and is quite convenient. For packaging and transportation, we basically use galvanized steel strip packaging trucks for packaging and transportation in China. This kind of portal scaffolding, the most important thing is to maintain a long life, and there is no need for maintenance during the effective life, which is very worry-free and labor-saving.
Advantages of portal scaffolding:
The geometric dimensions of portal scaffolding are standardized.
The structure is reasonable, the bearing performance is good, the strength of steel is fully utilized, and the bearing capacity is high.
It is easy to assemble and disassemble during construction, high in erection efficiency, labor-saving, time-saving, safe, reliable, and economical.
Disadvantages of portal scaffolding:
There is no flexibility in the size of the frame. Any change in the frame size must be replaced with another model of portal scaffolding and its accessories.
The cross brace is easy to break at the middle hinge point.
The shaped scaffold is heavier.
The price is more expensive.
Adaptability of portal scaffolding:
Construct stereotyped scaffolding;
Support frame for beam and slab frame (to bear vertical load);
Construct a movable workbench.
Above we have made a related introduction to portal scaffolding. Like other types of scaffolding, portal scaffolding has not only advantages, but also defects. When choosing portal scaffolding, on the one hand, it depends on the demand situation, and at the same time, it needs to be compared with other types of scaffolding.
