Scaffolding is a commonly used temporary support structure in construction projects, consisting of steel pipes (48.3 * 3.6), fasteners, scaffolding, adjustable supports, and cantilever scaffolding made of steel. It is used to provide a convenient and safe working platform during the construction process, providing conditions for construction workers to stand, work, transport, and also facilitating equipment installation, material transportation, and other work. Therefore, scaffolding plays an irreplaceable role in construction projects..
