The components that make up scaffolding vary widely based on the type of building, project requirements, and surrounding conditions of the construction. However, there are some fundamental scaffolding parts that form the basic structure of any scaffold.

Base plates, also referred to as sole plates, are the load-bearing base of a scaffold.
They're used to distribute weight and support the vertical scaffolding poles known as standards. Connecting the base plates to standards ensures a strong scaffolding foundation.
Base jacks are usually made out of steel and are adjustable to various lengths. The adjustments are made based on the amount of weight it needs to bear. They can also be made in a variety of configurations, such as swivels that adjust to sloped ground.
For scaffolds that are built off other structures like steel beams, base plates can be replaced with shoring heads (U-heads, for example).
Standards, also known as uprights, verticals, or legs, are the long pipes or tubes that connect the whole scaffold to the ground.
Standards play a role in transferring the entire load of the scaffold to the ground. As mentioned above, they're usually connected to base plates to ensure equal distribution of the load.
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.
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, or a coupling pin, 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.
Also referred to as runners, ledgers are tubes that run horizontally along the length of the scaffold.
This component is used to support the working platform of the scaffold. Based on its placement, it determines the height at which the working 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.
Transoms, or bearers, are horizontal members that meet the ledgers at right angles.
The role of a transom depends on the type. Main transoms provide support for the standards and the working platform by holding them in position. Meanwhile, intermediate transoms provide additional board support when placed at intervals between the main transoms. Another variant is putlogs, a type of transom with a flat end at one side, which is attached directly into the building wall to support working platforms.
The main transoms are positioned right next to the standards, while the intermediate transoms are attached to the ledgers in between the main transoms. Both of these components are made out of either steel, or aluminum.
Boards, also known as decks or battens, are the planks that form the working platform on a scaffold.
They're used as support for workers to stand on and place their tools when working on the scaffolding. Besides providing standing support, boards also ensure workers' safety when working at tall heights.
Boards are available in wood, aluminum, aluminum frame with plywood board, or hot-dip galvanized steel materials. Accessories such as guardrails and toeboards can be added for security against falls.
Couplers, also known as clamps, fittings or clips, are what hold components of a scaffold together. They're different from a scaffolding tie, which is used to connect the scaffold itself to other structures.
Couplers are mainly used to help connect structural elements of a scaffolding. 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.
Couplers 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.
Couplers are used extensively in tube and coupler scaffolds, whereas systems scaffolding drastically reduces the need for couplers through the built-in connections between nodes on the verticals and connectors on the ends of horizontal members.
Braces are diagonal tubes that reinforce the scaffold's rigidity.
Bracing 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 braces. Cross (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.
Braces are made from galvanized steel, an industry standard for heavy-duty support. In bamboo scaffolding, bamboo braces are used.
According to Federal labor statistics, there are more scaffold injuries related to planks giving way than any other cause. In addition to that, approximately 25% of workers using scaffolding do not get any training or guidance on how to properly install work platforms. This means that you need to choose the right scaffold boards for your broad, AND train your workers with how to properly install and use scaffold boards.
Scaffold planks are a critical aspect of your scaffold system. If you're a builder, don't make the mistake of assuming that any type of scaffold board will suffice! It is important to understand that scaffold boards must meet the strict guidelines that are set by OSHA. In addition, each scaffold must be tested to ensure that they can support the weight of materials and workers alike.

There are a number of factors to selecting the right scaffold boards for the job. For example, consider material, overall quality, load capacity, length, width, durability, and whether it has a non-slip surface. Let's look more into scaffold boards below:
Shop Scaffold PlanksWhen identifying the proper scaffold plank size, you will need to consider the type of work you'll be doing. You'll also need to be aware of the distance between frames. Here are some tips to consider for your scaffold board:
OSHA requires a minimum of 6 in. of overlap on either side of the scaffolding frames. This means that your scaffold boards need to be a minimum of 1 ft. longer than the span between the frames. Also, when creating a long platform that connects multiple spans of frames, the board overlap must not be less than 12 in. This is true unless the boards or platforms are secured to reduce movement.
The size of scaffold boards should be chosen based on the dimensions of the scaffolding system and the requirements of your building project. Ensure that the boards are long enough to overlap scaffold supports by a minimum required distance, providing stability and preventing tipping. Here are some of the most common scaffold plank sizes that are commonly used for building:
If you have any questions about scaffold plank sizing, please don't hesitate to reach out to our team for help.
We've alluded to this already, but make sure that you choose the right scaffold board to accommodate your load capacity. Your scaffold boards should be able to handle the combined weight of workers, tools, and materials. The strength and thickness of the board will determine its load-bearing capacity.
It's essential to ensure that the boards you select can safely bear the maximum anticipated load. Whatever load capacity you choose, ensure it adheres to quality standards set by OSHA or ANSI.
The most common materials used for scaffold boards are timber and metal (often steel or aluminum). Timber boards, such as those made from pine, are traditional and offer good grip, especially in wet conditions. However, they require regular inspections for cracks, warps, or other damages. Timber scaffold boards are often treated to enhance their durability and resistance to the elements, fungal decay, and insect attack.
On the other hand, metal boards are more durable and resistant to wear and tear but can become slippery when wet. Having a non-slip surface can prevent many accidents. Some scaffold boards even come with a built-in anti-slip surface, while others might require the addition of non-slip mats or covers to help ensure safety during use.

Also, another question you may have is 'how can I recognize board wear?' If you are using older scaffold planks, you may notice some wear and tear. Some signs that it's time to invest in new scaffold boards include the presence of: end splits, warping of the board, narrow face splits, face breaks, saw kerfs (or saw cuts), decaying of the wood, and drilled holes or dents in the surface of the wood. Read more here for understanding board wear and how to prevent it.

Shop NowWhen choosing scaffold boards, you'll find that they're typically made from two main materials: timber and metal. Timber is a traditional choice and offers a natural grip, especially in damp or wet conditions. It provides a warm and non-conductive surface, making it comfortable for workers in various weather conditions. On the other hand, metal scaffold boards, typically made of steel or aluminum, offer enhanced durability and resistance to wear and tear. Metal boards are often chosen for projects where longevity and low maintenance are prioritized, although they can become slippery when wet.
The thickness of scaffold boards can vary based on their intended use, material, and manufacturing standards. While there are thicker options available for specific heavy-duty applications, the standard for many boards is around 38mm. Metal scaffold boards can also vary in thickness, but they are often designed to provide equivalent strength and load-bearing capacity as their timber counterparts.
Timber scaffold boards are predominantly made from softwood species due to their flexibility, affordability, and availability. The most commonly used woods for scaffold boards include spruce pine. These woods are chosen for their strength, durability, and resistance to environmental factors when appropriately treated. To enhance their lifespan and ensure safety, these wooden scaffold boards are often treated against fungal decay, insect attack, and other potential damages.
Scaffold boards can be purchased from a variety of sources. Specialized construction supply stores often carry both timber and metal scaffold boards. Many larger home improvement stores or builders' merchants will also stock them. Additionally, for those looking for bulk orders or specific types, manufacturers and wholesalers can be a good option. It's always essential to ensure that any supplier meets both safety and quality standards. Purchasing from a reputable dealer like Badger Ladder guarantees that the boards adhere to the necessary standards, ensuring safety and reliability for your construction project.
Ultimately, choosing the right scaffold board for your building project is critical for the safety of your workers and the overall efficiency of your project. Before purchasing your scaffold planks or beginning any work, always consider the size and load limits of the planks. And, of course, always be sure you are purchasing from a company who sells products in compliance with OSHA standards.
