Frame system scaffolds are widely used in everyday buildings, and we will discuss them today.

Advantages:

(1) the geometric dimensions of the portal steel tubular scaffold are standardized.

(2) reasonable structure, good mechanical performance, full utilization of steel strength, high bearing capacity.

(3) it is easy to install and dismantle in the construction, high efficiency, safe and reliable, economical and applicable.

Disadvantages:
