Steel And Aluminum Scaffolding Standards Size

Mar 29, 2024

      While steel and aluminum scaffolding each have their own advantages, the key to correctly selecting and using either type of scaffolding is understanding their standard sizes and applicable standards. Different countries and regions have different requirements for the safety regulations and standard dimensions of scaffolding.

      This article will take an in-depth look at the standard sizes of steel and aluminum scaffolding to help building and construction professionals make an informed choice based on project needs.


Analysis Of The Advantages And Disadvantages Of Steel Scaffolding


  • The advantages include high strength, good stability and durability;
  • The disadvantages are heavier weight and relatively complicated installation and disassembly.


Analysis Of The Advantages And Disadvantages Of Aluminum Scaffolding


  • The advantages are light weight, convenient installation and disassembly, and strong adaptability;
  • The disadvantages are relatively low load-bearing capacity and high cost.


Steel Scaffolding Standard Sizes  ( Same As Aluminum Scaffolding) 

Pole (vertical pole) dimensions

  • Length: The standard length of vertical poles usually ranges from 0.5 meters to 3 meters to adapt to construction needs of different heights. In the construction of high-rise buildings, the required height can be achieved by connecting multiple vertical poles.
  • Diameter: the diameter of the pole is generally 48.3mm, and the wall thickness is about 3.2mm, which is a standard size, which can meet the load bearing capacity and stability of horizontal rod Dimension of pole
  • Length: The length of the pole is different, and the length used for construction is generally 0.9m, 1.2m, 1.5m, 1.8m and so on.
  • Diameter: The diameter is also the same as the pole, which is 48.3mm in diameter, which can ensure that the pole is connected in a stable manner with the horizontal pole 0.7.9 Diagonal pole Dimension of oblique pole
  • Length: The length of the oblique rod is determined by the angle and the distance required to support it. There is no standard length, and it is often adjusted according to the actual situation at the construction site.
  • Diameter: the diameter of the oblique rod is also 48.3mm.

Key Dimensions Of Scaffolding In Different Countries



In the U.S., WAC specifies the design and safety measures that need to be followed during the setting up, handling and dismantling of a range of different types of scaffolding, which are also referred to with regards to the length of their sole boards, or working platforms.



In the U.K., scaffolding on site in construction work is governed by the standard "Temporary works facilities" standard (BS EN 12811-1) and a commonly-respected set of practice guidelines called TG20, which deals with specific solutions to be used in relation to scaffolding erection and use.


Europe Countries other than the U.K., generally follow a set of European Standards (EN), such as EN 12811-1, which provides performance and general design requirements that need to be satisfied in order to ensure the safe use of scaffolding, which is also mirrored by similar versions in use in other countries.



In Australia, scaffolding is regulated by the AS/NZS 1576 series of standards. In particular, AS/NZS 1576.1:2010 sets out the minimum requirements for the design, construction, installation and usage of scaffolding in an attempt to provide better control over the risks involved with scaffolding on construction sites.



The design and use of scaffolding in China follows national standards such as GB 51210-2016 "Safety Inspection Standards for Building Construction", which provide detailed instructions for the design, use and safety requirements of scaffolding to ensure construction safety.



Despite the existence of international standards, particular scaffoldings in design and use should be consistent with local laws and codes. Standard dimensions and the specifications are subject to revision as new technologies emerge and safety standards are perfected. Before setting up and operating scaffoldings, knowledge of the applicable safety standards and operational procedures should be known by all.


Scaffolding Selection Guide

  1. Engineering Requirements: The specific needs of your project can influence your choice of scaffolding. For instance, if your project is extremely heavy-duty and will last several years, steel scaffolding may be the better option. On the other hand, if your project requires frequent movement of the scaffold or quick erection, aluminum might be the better choice.
  2. Cost Considerations: What is your project budget? Which type of scaffolding will be most cost-effective? Although aluminum scaffolding has a higher initial cost, it is lighter and faster to erect, and so in many cases ends up being the most cost-effective scaffold.
  3. Environmental Factors: Think about the environment your scaffold will be in. If your building site is wet or marine-based, you could particularly benefit from the corrosion resistance of aluminum scaffolding.
  4. Safety and Regulations: Is your scaffold fully compliant with local safety standards and regulations?


Main Using Of Steel Scaffolding :

Steel scaffolding is commonly used steel pipes and couplers, the material is widespread and the steel tube has high strength. Therefore, steel scaffolding is generally used in the following construction: 

  • Large public works: such as the construction of the stadium, the construction of the convention and exhibition center, the construction of large bridges and tunnel dishes.
  • Industrial facilities construction: which are steel pipes to stabilize large facilities in the construction of petrochemical, power, metallurgy, and other industrial facilities of the erecting and maintenance work.
  • The construction of shopping malls and other facilities: roundstings are a great deal of construction steel connecting steel scaffolding. Restoration and protection of ancient buildings: It's suitable for the structure with laying five times roundstakes by one-way construction


Main Using Of Aluminum Scaffolding

The main application of aluminum scaffolding Material: the main types of aluminum alloy scaffolding materials, material, light weight, corrosion resistance, Alloy scaffolding is usually quick to assemble and disassemble, and there are many kinds of axis scaffold used for indoor and outdoor decoration, maintenance, cleaning, etc. .

  • Temporary construction projects: such as the temporary stage, the temporary exhibition shelf of the large-scale event, the temporary auditorium, and so on.
  • Installation and maintenance of the billboard: it is more convenient to move to construct high or high altitude equipment for lifting the billboards.
  • The operation of the light industry: It is applied to the light industry and the special industry of many aluminum alloy staircases at home and abroad. Special needs are also available in special needs.
