The typical scaffolding arrangement consists of boxlike structures

Many construction and renovation projects require the use of scaffolding to allow workers to reach the upper areas of the project. The typical scaffolding arrangement consists of boxlike structures that can be stacked on top of each other until the desired height has been reached. In order to allow the workers to reach the work area more comfortably, scaffolding brackets are attached to the scaffolding. Once attached, a wooden or aluminum walking plank is placed onto the scaffolding brackets. The plank provides a working platform for the workers to operate on in close proximity to the structure.

While the most common style of scaffolding brackets consist of painted steel construction, there are also galvanized steel brackets that are designed to be used in masonry applications. The galvanized finish of the scaffolding brackets allows the dried-on concrete to be removed more easily than a painted finish, and the chemicals in the concrete and mortar will not corrode the brackets as rapidly as the painted surfaces. The strength of the brackets not only allows two or more workers to operate on a single walking plank — they provide enough strength to allow a surplus amount of cement blocks, bricks and mortar to be stocked on the plank as well.
Occasionally, concrete blocks will be hung on individual scaffolding brackets gyqdlqha, placed on the back side of the scaffolding to be used as counterweights or ballast. The ballast is commonly needed to offset the weight of the workers operating on the front side of the scaffolding. The most common type of attachment method for scaffolding brackets is to simply slide over the scaffolding tubes and lock on by fitting securely over the tubular structure, however, some brackets use a thumb screw to physically fasten to the scaffolding and prevent slipping.
