Hello Pipe Enthusiasts!
On this edition of #BPIPipeInsights, we will discuss how to choose the right steel pipe for the scaffolding industry. In the construction sector, scaffolding is a vital element that ensures worksite safety across various projects. One of its key components is the pipe, where quality and wall thickness directly affect structural strength. Yet in the field, we often find variations in pipe specifications that do not match Indonesia’s National Standard (SNI).
Does every “non-SNI” pipe automatically mean it's unsuitable? Not exactly
Many manufacturers adopt “internal standards” or “project specifications” tailored to specific needs (e.g., short-term, lightweight, or non-permanent projects). Scaffolding manufacturers have a direct role in ensuring safety on-site, one of which is selecting quality piping. Thin-wall pipe doesn’t automatically mean it's unfit, but it must be used within its intended capacity and always accompanied by clear inspections and SOPs.
Some temporary projects or short-term work sites intentionally choose lighter pipes for efficiency, especially amid price competition and diverse market demands. However, for primary scaffolding structures, wall thickness and compliance standards should remain top priority.
In dynamic work environments, pipe selection for scaffolding must be adapted to project duration, workload, and potential risks. The right product supports worksite safety without inflating project cost.
Understand the Indonesian National Standard (SNI) for Steel Scaffolding
Indonesia’s National Standard (SNI) for Steel Scaffolding defines the technical specifications required for scaffolding pipes. Key points include:
- SNI 03-1734-2002: Regulates material type, minimum thickness, and mechanical performance of scaffolding-grade steel pipes.
- Tensile & Hardness Tests: Each production batch must pass a minimum tensile strength of 235 MPa and surface hardness inspections.
- Dimensional Checks: Outer diameter (48.3 mm) and wall thickness follow the Light category (≥ 2.90 mm) or Medium category (≥ 3.20 mm).
- Label & Certification: SNI-certified pipes must display the SNI number, production date, and manufacturer identity.
Complying with this standard helps ensure structural integrity, minimizes the risk of worksite accidents, and meets audit requirements for work safety.

Beyond SNI: What International Standards & Internal Specs Apply to Scaffolding?
Other commonly used references include:
- JIS (Japan Industrial Standard): Wall thickness 2.4–2.5 mm, popular for tubular scaffolding.
- BS 1139 (British Standard): Wall thickness 3.2–4.0 mm, used for heavy-duty scaffolding.
- EN 12811 (European Norm): Focuses on load capacity and structural performance rather than specific thickness.
- Internal Specifications: Wall thickness of 1.3–2.0 mm used for temporary setups and cost efficiency.

Summary: How to Choose the Right Scaffolding Pipe?
- Determine project duration and load type (light, medium, heavy).
- Use SNI Light for lighter platforms and SNI Medium for main structures with medium-to-heavy loads.
- SNI Light & SNI Medium are recommended for main scaffolding structures.
- For auxiliary scaffolding components with pipe sizes below 1½ inch (such as ½ inch, ¾ inch, 1 inch, and 1¼ inch), you may rely on our products BOS, SIO, and XL for cost-efficient add-ons.
- For non-SNI use in main structures, ensure it suits mobile or event setups and follows strict inspection SOPs.
- Always follow proper installation procedures and safety checklists.
- Involve your QA/QC team at every stage, from receiving materials to installation.
