description

The CupLock Intermediate Transom (Painted) is an important component in the CupLock scaffolding system, providing horizontal support between the vertical scaffold standards and the horizontal ledgers. When painted instead of galvanized, the transom receives a protective layer of paint, which helps to prevent corrosion and improve its longevity, though it may not offer the same level of durability in harsh environments as Hot-Dip Galvanized (HDG) components.

key features

The CupLock Intermediate Transom (Painted) is designed with several important features that enhance its functionality and safety:

• Material: Typically made from steel and coated with a protective paint layer to resist corrosion. The paint serves as a barrier to prevent rust and corrosion.
• Shape and Function: The transom is typically a rectangular or I-beam shape, designed to be inserted between scaffold standards and ledgers, providing a stable base for scaffold boards or metal decking.
• Corrosion Protection: The painted finish provides a degree of protection against corrosion, but it is more susceptible to wear and tear compared to HDG-coated parts. Over time, the paint may degrade, especially when exposed to harsh conditions.
• Load-Bearing Capacity: The transom is designed to withstand heavy loads, but the specific capacity will depend on the size and material strength of the component. The load-bearing capacity must meet the requirements outlined in BS 1139, EN 12811-1, and other safety standards.
• Ease of Assembly: The CupLock Intermediate Transom (Painted) is designed to be easily installed by placing it into the CupLock couplers on the scaffold tubes, locking it into place without the need for additional fasteners or bolts.

uses

The CupLock Intermediate Transom (Painted) is an ideal solution for a variety of tasks that require reaching elevated spaces. Key uses include:

• Support for Scaffold Platforms: The primary function of the CupLock Intermediate Transom (Painted) is to provide horizontal support for scaffold planks or metal decking. This ensures that the platform is stable and can safely hold the weight of workers and equipment.
• Light to Moderate Duty Scaffolding: Painted transoms are suitable for scaffolding systems in areas where the environment is relatively mild and corrosion is not a significant issue. For example, in indoor construction projects or areas with minimal exposure to moisture or harsh chemicals, painted transoms provide adequate protection and performance.
• Temporary Scaffolding: Painted CupLock Intermediate Transoms are often used in temporary or short-term scaffolding applications, where they are exposed to fewer environmental stresses and corrosion risks. These transoms may be used in maintenance or building renovations that are expected to be completed quickly.
• Construction and Access Platforms: The transoms help provide access for workers at height, making them integral to scaffolding systems on building sites, where horizontal stability and platform support are required for safe working conditions.
• Formwork and Shoring: Similar to HDG transoms, painted transoms are used in formwork and shoring applications, where they support the weight of wet concrete or act as temporary support during the curing process. The paint coating offers protection, although it may not withstand harsh outdoor environments as well as HDG.

standards

Several international standards apply to the design, materials, and performance of scaffolding components, including the CupLock Intermediate Transom (Painted). These standards ensure the safety, stability, and durability of the scaffolding system.

• BS 1139 (British Standard): The primary British standard for scaffolding materials and systems. It specifies the strength, design, and safety requirements for scaffold components, including the CupLock Intermediate Transom. The standard ensures that painted transoms meet the minimum performance and load-bearing requirements, ensuring they can safely support the scaffold platform.
• EN 12811-1 (European Standard): Sets out the performance requirements for temporary scaffolding structures. This includes specifications for load-bearing capacity, design, and stability, which are relevant for the CupLock system, including the intermediate transoms. The painted transoms must comply with these standards, ensuring they provide adequate strength and safety for scaffolding users.
• EN 74 (European Standard): Covers scaffold couplers and related components, such as the CupLock coupler that locks the intermediate transoms in place. The standard ensures the security and strength of connections between components, preventing accidental dislodging or failure during use.
• OSHA Regulations (USA): Outlines requirements for scaffolding systems in the United States. The CupLock Intermediate Transom (Painted) must adhere to OSHA standards to ensure that the scaffolding is safe for workers and can handle the loads imposed during use.
• ANSI A10.8 (American National Standards Institute): Provides guidelines for the safety of scaffolding systems in the United States. It includes requirements for component strength, safety, and design. The painted transoms must meet these standards to ensure they are capable of supporting the loads typical in construction and maintenance tasks.
• ISO 9001 (Quality Management System): Ensures that the manufacturer of the CupLock Intermediate Transom follows a strict quality management process. This certification guarantees that the transoms are produced to high-quality standards, with proper testing, material selection, and adherence to safety regulations.
• Paint Coating Standards: While HDG provides long-term corrosion resistance, painted coatings generally comply with specific paint standards (such as ISO 12944 for corrosion protection) to ensure that the paint is adequately applied and can resist environmental factors like weathering, moisture, and chemicals, though it may wear out faster than HDG coating.

conclusion

The CupLock Intermediate Transom (Painted) is a vital part of the CupLock scaffolding system, providing horizontal support for scaffold platforms. The painted finish offers corrosion protection, making it suitable for indoor or temporary scaffolding applications, where long-term corrosion resistance is not as critical. It is commonly used for construction, maintenance, and access platforms where environmental conditions are less harsh. By meeting international standards such as BS 1139, EN 12811-1, and OSHA regulations, the painted transom ensures safe and reliable scaffolding.
