Product Introduction

Tianjin YOUFA International Trade Co.,Ltd is one of the most experienced manufacturers and suppliers of scaffolding pipe standard sizes in China. Welcome to wholesale bulk high quality customized produts at low price from our factory. For price list and cheap products, contact us now.

Scaffolding pipes are galvanized steel tubes hot rolled into round shapes with a standard diameter of O.D 48.3mm (BS1139 EN39).They are joined by scaffolding couplers and fittings in construction to form all types of scaffolding.Youfa scaffolding pipes are manufactured to meet uk scaffolding standards BS1139 and Europe standards EN39, versatility for various construction and industrial applications.

Scaffolding Pipe Standard Sizes covers many aspects such as outer diameter, wall thickness, length, material, surface treatment, weight, tolerances, load capacity, standards and certifications etc.

scaffolding pipe standard Outer Diameter

Scaffolding pipe international standards:
EN39/BS1139: 48.3mm (corresponding to the old 1.5-inch nominal inner diameter, now standardized as outer diameter).
Japanese/Korean Standards (JIS 3444): 48.6mm.

Scaffolding pipe chinese standards:
GB/T 13793: commonly 48mm (some use 48.3mm), typical for coupler-type scaffolding.
Ringlock Scaffolding: vertical pipes have an O.D. of 60mm (e.g., Q345B steel), while horizontal pipes use 48mm.

Outer diameter tolerance: ± 0.5mm (EN39/BS1139); ± 0.5mm (Chinese 48mm pipe).

Scaffolding Pipe Standard Wall Thickness

Scaffolding tube standard wall thickness: 3.2mm (commonly used) or 4.0mm (reinforced).

Wall thickness tolerance: ± 10% (BS1139); ± 15% (EN39).

3.2mm: Suitable for general construction projects.

4.0mm: Suitable for heavy-duty or high-risk projects (such as industrial plants, bridges).

Importance: Wall thickness directly affects the load-bearing capacity and durability of steel pipes.

Scaffolding Pipe Standard Material and Surface Treatment

Common materials:
Carbon Steel: Such as Q235, Q345 (Chinese standard) or S235JR, S355JR (European standard).
Galvanized Steel: Hot dip galvanizing or pre galvanizing to improve corrosion resistance.
Importance: The material determines the strength, durability, and applicable environment of the steel pipe
Common handling methods:
Hot Dip Galvanizing: Zinc layer thickness ≥ 85 μ m, suitable for corrosive environments.
Pre Galvanized: The zinc layer is relatively thin and suitable for general environments.
Painted: Mainly used for indoor or short-term projects.

Importance: Surface treatment directly affects the corrosion resistance and service life of steel pipes.

Scaffolding Pipe Standard Length

Scaffolding Standard length: 1m, 1.5m, 2m, 2.5m, 3m, 4m, 5m, 6m.

Length tolerance: ± 10mm (standard length)

Customized length: Youfa scaffold tubes can be customized according to project requirements.
Importance: The length determines the modular design and construction efficiency of the scaffold.

Scaffolding Pipe Weight

Calculation formula: Weight (kg/m) = 0.02466 × Wall Thickness (mm) × (Outer Diameter - Wall Thickness) (mm).
Examples:
48.3mm × 3.2mm: Approximately 3.5 kg/m.
48.3mm × 4.0mm: Approximately 4.4 kg/m.
Importance: The weight affects the transportation cost and construction efficiency.
