In industrial engineering and construction, scaffolding refers to a temporary, modular structure designed to support workers and materials during the maintenance or assembly of complex systems.
To ensure structural compatibility, these systems follow strict national standards; for instance, the Japanese specifications under JIS G 3444 specify an outer diameter of 48.6mm for scaffolding tubes.
Beyond the standard 2.4mm wall thickness with a tensile strength of 500 N/mm², scaffolding is also available in lightweight yet high-strength versions made from high-tensile steel, featuring a 1.8mm thickness and a tensile strength of 700 N/mm²
The durability of scaffolding depends on the coating method used, such as pre-galvanizing, hot-dip galvanizing, or in-line galvanizing. Each method offers different levels of performance and corrosion resistance.
Furthermore, technological advances in scaffolding clamps and joints—the essential interlocking hardware—have facilitated broader adoption of these systems. As these components become increasingly accessible via home improvement stores and online, the utility of scaffolding has expanded from traditional temporary works, finding broad applications in modular DIY projects and bespoke industrial design.
Daiwa Steel Tube Industries (DSTI) in Japan, a core company of the one to ONE Group, is engaged in the manufacturing of scaffolding tubes using high-tensile materials.
