Sizes of Scaffolding Boards

Scaffolding boards make up an integral structure in the construction of any type of scaffolding: these boards provide floor space for the construction workers to walk, work and make their way around the scaffolding safely. 

As scaffolding walkways are incredibly important when it comes to the safety and integrity of the scaffolding structure, most contractors will stick to certain sizes of scaffolding boards to ensure the security of their workmen and the durability of their scaffolding. In this article, I’m going to give you the run-down on all the various sizes of scaffolding boards, what sizes of scaffolding boards are best for various uses, and I’ll respond to some frequently asked questions about sizes of scaffolding boards. 

What are the standard sizes of scaffolding boards?

Scaffolding boards can be quite typically uniform in size when used for general construction projects, but for each different type of scaffolding board you can expect to find different recommended dimensions.

Sizes and Dimensions for Different Types of Scaffolding Boards:

There are several different types of scaffolding boards to pick from when you’re embarking on a construction project, all of which will come with different recommended sizes and dimensions. If you’re planning to use scaffolding boards for work on DIY or home furniture, you might want to opt for higher quality BSI scaffolding planks and choose the smaller sizes. If you’re going to be working through extreme weather or in dangerous conditions, you might prefer to opt for galvanized steel scaffolding planks for enhanced durability and longevity. Here are the various types of scaffolding boards and their accompanying sizes:

Scaffolding Board Sizes: Grade A Dimensions

This is the most common type of scaffolding board, and will typically come with the standard-sized scaffold plank thickness of 38mm, and 225mm across in width. Most Grade A scaffolding planks will be made with European Whitewood and adhere to BS2482 UK standards. You can find Grade A scaffolding boards in the following sizes, with the weight rounded up for brevity and as a general estimation:

  • 13ft (19kg)
  • 10ft (14.5kg)
  • 8ft (11.8kg)
  • 6ft (8.7kg)
  • 5ft (7.31kg)

These scaffolding planks are great for providing sturdy structures for outdoor construction work and giving your scaffolding a sturdy, balanced interior. 

Scaffolding Board Sizes: BSI 1.2m standard board 

BSI standard board sizes adhere to BS2482 UK standards and are of moderately better quality than Grade A scaffolding boards. These dimensions are the same as the dimensions of the Grade A scaffolding boards and have the same thickness of 38mm and width of 225mm. 

You can find BSI (1.2m) standard boards in the following sizes, with the weight rounded up for brevity and as a general estimation:

  • 13ft (19kg)
  • 10ft (14.5kg)
  • 8ft (11.8kg)
  • 6ft (8.7kg)
  • 5ft (7.31kg)

Scaffolding Board Sizes: Flame resistant scaffolding boards

If you or your contractor needs flame-resistant scaffolding boards, you can find these boards in the same dimensions as the Grade A and BSI scaffolding boards. Flame retardant scaffolding boards will have the same 38mm in thickness and 225mm in width, and are fire-resistant – the wood will be pre-treated with flame retardants to keep your scaffolding structure and work workers safe while working in flame-hazardous conditions. 

You can find flame retardant scaffolding boards in the following sizes, with the weight rounded up for brevity and as a general estimation:

  • 13ft (19kg)
  • 10ft (14.5kg)
  • 8ft (11.8kg)
  • 6ft (8.7kg)
  • 5ft (7.31kg)

Scaffolding Board Sizes: Supadeck plastic scaffolding boards

While most contractors will opt for wooden scaffolding boards manufactured using the classic European whitewood, many prefer to opt for plastic instead. Supadeck is a popular plastic substitution for wooden scaffolding boards, and some contractors prefer them as they’re more durable when it comes to water damage, natural decay, and general deterioration. Plastic scaffolding boards will last longer than traditional scaffolding boards, but won’t be able to provide you with that rustic, authentic scaffolding wood look. These scaffolding boards will be 38mm in thickness and 225mm in width, as with all the other scaffolding planks. 

You can find plastic scaffolding boards in the following sizes, with the weight rounded up for brevity and as a general estimation:

  • 13ft (16kg)
  • 10ft 1(2.5kg) 
  • 8ft – (10kg) 
  • 6ft – (7.3kg) 
  • 5ft – (6kg)

Scaffolding Board Sizes: Galvanised steel scaffolding boards 

If your construction work is taking place in a harsh environment and you’re looking for durable, long-lasting scaffolding boards designed to go the distance, you might want to opt for galvanized steel scaffolding boards. These scaffold boards are flame resistant and ideal for long-term investments and long projects. While remaining the same 38mm in thickness and 225mm in width, steel scaffolding boards are much heavier than the other boards listed. You can find galvanized steel scaffolding boards in the following sizes, with the weight rounded up for brevity and as a general estimation:

  • 13ft (22kg)
  • 10ft (17kg)
  • 8ft (13kg)
  • 6ft (10kg)
  • 5ft (8.50kg)

FAQs: Sizes of Scaffolding Boards

What are the best sizes of scaffolding boards for my needs? 

When it comes to buying scaffolding boards, it’s best to seek advice from a qualified expert, especially when embarking on a construction project. A scaffolding expert will be able to tell you what sizes will be best suited to your project. 

On the other hand, if you’re using scaffolding boards for DIY use, you should stick to the small sizes, to begin with. Not only are scaffolding boards heavy, but you’ll need to make sure your accompanying tools and equipment (for example, brackets for shelves) will fit the board’s hefty 38mm thickness.

What can I do with scaffolding boards?
