Certified scaffolding

Types of Certified Scaffolding

There are several types of certified scaffolding in the market. Here are the main ones:

• Frame Scaffolding

  Frame scaffolds consist of a metal framework. They are among the most common types of certified scaffolding. The metal framework is made up of two vertical poles and cross bars. The vertical tubes are also known as standards. They support the weight and provide stability. The cross bars are also called ledgers. They connect the vertical poles. Additionally, they create a platform where workers stand. Frame scaffoldings are easy to set up and disassemble. They are also very stable and provide maximum support.

• Rolling Scaffolding

  These are temporary structures for construction projects. They are made of steel or aluminum. They consist of two horizontal beams, vertical beams, and a platform. The horizontal and vertical beams form a rectangular structure. They have wheels at the base of the structure. The wheels allow users to move the scaffolding from one place to another. They can be locked in position when users need stability. Rolling scaffolds are perfect for projects that need movement. For example, painting or plastering walls.

• Single and Double Scaffolding

  Single scaffolding is made up of vertical posts. It is also known as brick scaffolding. The vertical posts are put up on the building that needs support. They hold ledgers, transoms, and bearers. Single scaffolding is mainly used for masonry work. On the other hand, double scaffolding consists of two rows of vertical posts. They are placed on both sides of the wall. This type is mainly used for scaffolding in areas with weak walls.

• Tube and Coupler Scaffolding

  These are versatile and can be used for different structures. They consist of steel tubes and couplers. The tubes are put together to form a scaffold. The couplers connect the tubes securely. They also create a stable platform for workers. Tube and coupler scaffolding is perfect for structures of different shapes and sizes.

• Scaffolding with a Cantilever and a Needle

  Cantilever scaffolding relies on beams. The beams are anchored to the structure. They project out to support the scaffold platform. Needle scaffolding involves supporting beams called needles. The needles are inserted into the structure. They distribute the weight to the walls.

Function and feature of certified scaffolding

• Hot-dip galvanization

  This is the most common type of certified steel scaffolding. The steel pipes are dipped in molten zinc to prevent corrosion. The zinc coating forms a hard bond with the steel, creating a long-lasting protective layer. Hot-dip galvanization is important for scaffolds because it increases their lifespan, especially in humid or coastal areas. The galvanized pipes can last 30 years or more with minimal maintenance.

• Aluminum

  Some certified scaffolding is made from aluminum alloy. Aluminum scaffolds are lightweight and easy to assemble and disassemble. They are good for projects where mobility is important. However, aluminum does not have the same load-bearing capacity as steel. Aluminum scaffolds are typically used for lighter loads or smaller projects.

• Couplers and joints

  Steel tubes are connected using couplers. There are different types of couplers, including:
  - Socket or welding couplers: Steel tubes are inserted into sockets or welded together. This creates a strong, rigid connection.
  - Clamp couplers: Steel tubes have clamps that fit over both tubes. Bolts are tightened to secure the connection. Clamp couplers allow for quick assembly and disassembly. They are also adjustable for different angles.
  - Swivel couplers: Two-piece couplers can turn 360 degrees. They connect tubes at any angle, useful for corners or irregular shapes.
  - Joint pin: This type of connection is pinned through holes in both tubes. It provides a secure, easily removable connection.
  The type of couplers and joints affects how the load is distributed across the scaffold. Rigid connections transfer more load, while swivel or clamp connections provide flexibility and ease of adjustment.

• Planks

  Planks create the platform for workers. They are usually made of steel or aluminum. Steel planks are strong and durable. They have a slip-resistant surface for safety. Aluminum planks are lightweight but still provide good load support. Some planks have a composite material that makes them slip-resistant and reduces noise.

• Bracing

  Bracing adds stability to certified scaffold. Diagonal bracing helps distribute the load and prevents the scaffold from swaying. Cross bracing forms a triangle, which is a stable shape. Single diagonal bracing is quicker to install but not as strong as cross bracing. Double bracing uses two sets of tubes and makes the scaffold very stable, especially for tall structures.

Scenarios of Certified Scaffolding

There are different scenarios where certified and non-certified scaffolds are used in the construction industry. All the parties involved in using and providing certified scaffolds, from manufacturers to retailers and end-users, must ensure that the scaffold is constructed, maintained, and inspected according to the set standards.

The following are some common scenarios where certified scaffolds are used:

• Construction sites: Scaffolds are used in most construction sites to support workers, materials, and tools during the building process. Certified scaffolds are constructed and designed to be adjusted to different heights and widths. They are also designed to be stable on uneven ground.
• Renovation projects: Renovation projects involve working on different parts of a building, which may require the use of scaffolds to safely access high or hard-to-reach areas. For instance, changing a building's roof, painting, or changing the windows. Certified scaffolds are essential in these scenarios to ensure the safety of the workers and complete the project successfully.
• Infrastructure projects: Large infrastructure projects, such as bridges and highways, require the use of certified scaffolds. This is because the projects involve working at heights and in different positions. Certified scaffolds provide a safe platform for workers to carry out their duties.
• Industrial plants: Industrial plants are large facilities where different products are manufactured. Workers may need to access high or hard-to-reach areas to perform maintenance or inspections. Certified scaffolds are used in these facilities to ensure the safety of workers.
• Shipyards: Shipyards are areas where ships are built, repaired, or maintained. Workers need to access different parts of the ships, which may be at heights or in tricky positions. Certified scaffolds provide a safe and stable platform for workers to carry out their tasks efficiently.
• Emergency rescue operations: Emergency rescue operations involve rescuing people trapped in high or hard-to-reach areas. Firefighters and other rescue teams use certified scaffolds to safely reach and rescue individuals in emergency situations.
• Event setups: Certified scaffolds are sometimes used to create platforms for lighting, videos, and other equipment in concerts and other events. This is done to ensure that the equipment is safely positioned and supported.

How to Choose Certified Scaffolding

When purchasing certified scaffolding for resale, business owners should consider several factors to ensure they make a sound investment. Here are some of them:

• Material

  Scaffolds are made of different materials, each with pros and cons. Aluminum is lightweight and rust-resistant, but it is less strong than other materials. Steel is durable and robust but also more heavy and prone to rust without proper coating. Businesses should pick the material that best suits their customers' expected projects and needs.

• Load Capacity

  Every type of certified scaffolding has a different load capacity. This refers to the maximum weight the scaffold can safely support. Load capacity is crucial for safety and should be considered when choosing a type of scaffold. Buy scaffolds with various load capacities to cater to different customers' needs.

• Height

  When choosing certified scaffolds, consider the maximum height required for different construction projects. Each scaffold is designed to reach a specific height. Therefore, business owners should buy several types to ensure their customers have the ideal scaffold for their construction project.

• Mobility

  Meters and base plates are essential when the scaffold is installed in a permanent location. However, certified scaffolds for resale should have adjustable leveling devices and sturdy casters. The castors should be locking to prevent movement when the scaffold is in use.

• Ease of Assembly

  Business owners should choose certified scaffolds that are easy to assemble and disassemble. This will save their customers' time and effort. For example, modular scaffolds require more time and skills to assemble, while prefabricated scaffolds are easy to assemble.

• Accessories

  Business owners should choose certified scaffolding that comes with essential accessories such as guardrails, toe boards, and access ladders. These accessories enhance the scaffold's safety and functionality. Business owners should also stock additional accessories to enable customers to get everything they need for their construction project.

• Compliance

  All the scaffolding should meet the local and international safety standards. Business owners should request the manufacturers' certification and inspection reports before placing their orders. Also, they can conduct a simple test to confirm the scaffold's stability and sturdiness.
