Types Of Scaffolding Componentry

Scaffold tubes typically have a standard outer diameter, with a common outer diameter of approximately 48.3 mm(1.5 inches in English units) and a common outer diameter wall thickness of 3.2mm or 4.0mm. The length of pipe scaffolding also varies. They usually have lengths of 1.5 m, 2 m, 3 m, 4 m, 5 m, and 6 m.
Galvanized scaffold tube have high strength and durability, and are usually galvanized to prevent rust and corrosion. Galvanizing involves applying a layer of zinc on steel. This zinc layer acts as a sacrificial anode, preferentially corroding the steel beneath it.
Scaffold pipe can be connected using various couplings. Right angle couplings are used to connect tubes at a 90 degree angle, while rotary couplings are used for angles outside of 90 degrees. These couplings ensure that the pipes are firmly fixed together and can effectively transmit loads. Steel scaffolding pipes are also compatible with other scaffold components such as scaffold boards, slant support, and baseplates. The diameter of the pipe is standardized so that other components can be easily connected and coordinated with the pipe to form a stable and fully functional scaffold structure.

Standards, also known as uprights, verticals, or legs, are the long pipes or tubes that connect the whole scaffold to the ground.To ensure even distribution of scaffold loads.As standards are of fixed lengths, taller scaffolding requires that the pipes be connected so as to route the load directly through the structure. This is accomplished by using the 'pin and socket' joint, which twists to lock successive pipes together.Standards are commonly made out of either painted steel, galvanized steel or aluminum, based on the requirements of the scaffold.

Scaffold base plates are used to distribute weight and support the vertical scaffolding poles known as standards. Connecting the base plates to standards ensures a strong scaffolding foundation.The base jack is usually made of steel and can be adjusted to various lengths, used to level scaffolding on uneven surfaces. They are typically used on outdoor construction sites where the ground may not be completely flat.

ledgers are tubes that run horizontally along the length of the scaffold.It is used to support the working platform of the scaffold. Based on its placement, it determines the height at which the steel planks (decks, boards) are staged.Ledgers are placed in between each standard and structured parallel to the building's wall. Multiple bays are connected with these ledgers both at the back and the front of the scaffold.In some scaffolding systems, the same component fulfills both the ledger and transom function, in which case both may be referred to as ledgers.The material used to create ledgers are either steel or aluminum.

Steel plate is a working platform on scaffolding, usually treated with moisture-proof and anti-corrosion measures. They need to be laid securely on the transoms to provide a safe working area.Used as a support for workers to stand and place tools while working on scaffolding, it also ensures the safety of workers when working at heights

Scaffold brace provides strength by controlling the "unbraced length" of the scaffold leg. Besides that, it increases the scaffold's stability by ensuring the scaffold leg doesn't fall over.There are several types of scaffold braces. Scaffolding cross braces (transverse) braces run diagonally between ledgers and standards to increase a structure's overall rigidity. Meanwhile, façade (longitudinal) braces are attached on the face of the scaffold, running diagonally along the length of the structure at every level. They help to prevent a structure from swaying. Braces are critical to keep scaffolds from twisting and ultimately collapsing due to loads as well as seismic, wind, and other external forces.

Scaffold couplers, also known as scaffold clamps, scaffold fittings or scaffold clips, are what hold components of a scaffold together and is widely used in tubular and coupler scaffolds.Scaffold clamps are used to connect the different scaffolding components together . But detailed utilization comes in several variants – Putlog Couplers, Swivel Couplers, and Right Angle Couplers. Putlog Couplers are used to connect a ledger to a transom when the connection is needed to support the working board. Right Angle Couplers are used to connect a ledger or transom to a standard, while Swivel Couplers are recommended for any other angle of connection between scaffold tubes, such as diagonal bracing.Scaffold fittings are usually made out of drop-forged steel or pressed steel for durability and reliability. Some have a hot-dip galvanized finish to avoid corrosion.
