Frame scaffolding, also known as tubular welded scaffolding, is a type of scaffold built from prefabricated frames used as temporary support in various construction projects.
Scaffolding frames are steel structures made up of two horizontal and two vertical tubes welded together. This design replaces the need for connecting standards and ledgers with fittings, enhancing efficiency and saving labor. The frames resemble an "H," hence the name H Frame Scaffolding.
Cross braces are typically made of two galvanized pipes connected to form an "X" shape. They attach to the locking pins on the frame to provide support and stability. The length of the cross brace is determined by the locking distance and scaffold board / platform length, with common sizes being 7’x 4’ and 10’x 4’.
Scaffold base jacks consist of a base plate and a threaded rod or tube welded together, with a nut for height adjustment. The outer diameter of the base jack should match the inner diameter of the frame leg, allowing it to be inserted for load distribution and ground leveling.
Scaffold boards are platforms placed on the top horizontal bars of the frames for material storage and worker access. They can be made from metal, aluminum, or wood.
Coupling pins are connecting pins with a collar riveted on the outside, fitted onto the frame legs to stack multiple scaffolding frames for different heights.
Guard rails are single galvanized pipes used when scaffolding height exceeds 42". Common sizes include 5’, 7’, and 10’.
There are various types of frame scaffolding components to realise different fuctions in the construction work. The above are some basic elements for your review. Click here to learn more components for frame scaffolding.
Scaffolding frames come in various types, with the most common being:
Most frames are made of steel, offering the best choice in terms of functionality and cost.
Often used as shoring frames in formwork due to their high load capacity and ease of transport and assembly. Aluminum frames are also used in mobile scaffolding for small indoor and outdoor jobs.
Also called ladder or step frames, with rungs on one or both sides for ladder functionality. Frames with rungs on both sides are called box frames.
Also known as arch frames, these are open at the bottom for easy passage and allow workers to traverse and work on multiple levels.
Also known as trestle frame scaffolding, it is foldable and used for single-story residential or wall masonry work, providing elevated access. Common sizes are 4’ and 6’.
A type of heavy-duty frame primarily used for support, different from other frames, and mainly for supporting concrete floors, ceilings, and excavation.
Developed by Layher, commonly used in Europe with U transoms and U-shaped platforms.
Another common European frame used in façade scaffolding, similar in appearance to the Layher frame but with different locking pins, using star pins on top.
Similar to walk-through frames but usually with diagonal braces welded to the top horizontal and vertical tubes, commonly used in Italy and surrounding countries.
In Australia and Brazil, scaffolding frames are used with minor differences in shape and size.

The best surface treatment for protecting frames, allowing for maximum usage and adaptability to various climates. However, due to its high cost, it is only used in projects with high environmental demands.
The most common surface treatment, more eco-friendly and with stronger adhesion than painting. It is less expensive than galvanizing and available in various bright colors like red, yellow, and blue, unlike the silver of galvanized frames.
Some customers, especially from Southeast Asia, choose pre-galvanized frames, made from pre-galvanized pipes welded and then painted. Although cheaper than hot-dip galvanized frames, we do not recommend them due to potential rusting at weld points and health risks during welding.
Frame scaffolding is used in residential, commercial, and industrial construction for tasks such as painting, roofing, window installation, masonry, plastering, and façade maintenance.
In these industries, scaffolding frames are used to create temporary structures like stages, lighting setups, and other required structures.
Flexibility: Suitable for various construction activities with a wide range of sizes and shapes, allowing for different heights.
Ease of Use: Prefabricated frames with pre-welded tubes reduce assembly and disassembly time, lower labor costs, and increase worker efficiency.
Durability: Made from high-strength steel (such as Q355) or aluminum, providing strong load-bearing capacity. Hot-dip galvanizing and powder coating prevent corrosion, adapting to various climates.
Visibility: Bright colors enhance safety by making scaffolding noticeable from a distance.
Scaffolding frames have no major downsides. However, they occupy significant space during production and transport, increasing shipping costs, especially for small orders.
The scaffolding and its components must support four times their rated load.
Use cross braces to keep scaffolding stable and secure.
Employ outriggers when stacking scaffolding frames.
Use base plates or base jacks.
Use guardrails or personal fall arrest systems above 10 feet to protect workers.
Train employees on scaffold assembly and disassembly before work.
Ensure all locking pins are in place before use.
OSHA requires scaffold platforms to be fully planked or decked with proper guardrails, mid-rails, and toe boards.
