Scaffolding Tube Ultimate Guide

What Are The Sizes of Scaffolding Pipes?

The standard diameter of a scaffold tube is 48.3mm O.D. The specific 48.3mm metric size is from the old measurement of inches of 1.5″.

In the old inch measurement, 1.5″ means the scaffold tube inside diameter. To avoid error and confusion, specific metric sizes are more popular and uniform nowadays.

In Japanese and Korean standards, the standard scaffolding pipe diameter is 48.6mm.

What is Scaffold Tube Made Of?

Scaffold tubes are made of steel or aluminum.

• Steel scaffold tubes are hot rolled and shaped into a round shape.
• Aluminum scaffold tubes are extruded from aluminum

Conclusion:  Aluminum scaffolding pipes are 2.5 times lighter than steel scaffold tubes (4.0mm steel tube 4.5KG/m, 4.0mm aluminum tube 1.56KG/m).

Steel Scaffolding Pipes

Steel scaffolding pipes are the best scaffolding pipes. It is made of high-strength steel structures. You can find welded steel scaffolding pipes and seamless steel scaffolding pipes in Wellmade.  Welded steel scaffold pipes are made of steel plates or steel coils. While seamless steel scaffolding pipes are made from steel round bars.

According to surface treatment, steel scaffold pipes include black scaffold tubes, galvanized scaffolding pipes, and painted scaffolding pipes.

Black Steel Scaffolding Pipes

Black scaffolding pipes are also called MS scaffolding pipes. It is a type of self-finished steel scaffolding pipe. Mainly required by scaffolding companies for further manufacturing of system scaffold(ringlock, cuplock, kwikstage, quick lock, shoring frames, frame scaffold) and beams(ladder beams, unit beams), etc.

Black scaffolding pipes are easy to rusty.  Thus the black scaffolding pipes need to be with special surface treatments to protect them from rust.

Painted and Galvanized Scaffolding Pipes

For anti-corrosion purposes, black steel scaffold tubes can be treated with further surface protection to extend the life of the scaffolding pipes.

According to the surface treatment way, there are definitely three types of scaffold tubes. Galvanized scaffold tubes, painted scaffold tubes, and powder-coated scaffold tubes.

Galvanized Scaffolding Tubes

Galvanized scaffolding tubes are black steel scaffolding pipes with zinc protection on the surface.

According to galvanizing temperature, condition, and process, there are three types of galvanized scaffold tubes: Hot dip galvanized scaffold tubes, GI Pipe, and E-galvanized pipes.

Hot Dip Galvanized Scaffold Tubes (HDG Tubes)

Hot-dip galvanized scaffolding pipes are also called HDG scaffold tubes. It is a step to cover black scaffold tubes with zinc thickness.

Hot dip galvanized scaffold pipes process:

• Steel black pipes go through a series of cleaning steps: degreasing, pickling, and fluxing.
• Dip the steel black tubes in the molten 450^oC zinc bath.
• Black steel scaffold tubes are covered with more than 40 micros (280g/sqm) thickness zinc.
• The zinc protects the scaffold pipes from rust.

With the extra zinc covered on, the weight of hot dip galvanized scaffolding pipes is about 3% heavier than black scaffold tubes.

GI Scaffolding Pipes

GI scaffolding pipes is called premier galvanized(pre-gal) scaffolding steel pipes. They are made of premier galvanized (GI) steel coils/plates.

Compare to hot dip galvanized scaffold tubes, GI pipes are with thinner zinc thickness. about 6-35 micro (42 g/m² to 245 g/m²). Thus the anti-corrosion function is not as good as hot-dip galvanized scaffolding pipes.

But GI scaffolding pipes are at less cost and cheaper price. That is why it is very popularly used.

GI pipes are normally for thinner wall-thickness steel scaffold tubes. The thickness of the GI pipes is up to 2.5mm.

Nevertheless, GI pipes are better than painted scaffold tubes in anti-rusty. That is why both hot-dip galvanized tubes and GI pipes are used widely in all pipe scaffolding constructions. Include civil, industrial, and infrastructural construction, pipe racking in onshore and offshore projects, chemical plant building, shipping building, maintenances of pipelines, equipment, building, etc.

BS1139 & EN39 Standard Steel Scaffolding Pipes

BS1139 and EN 39 standard scaffolding pipes are the most used globally wide. You can download  BS1139 and EN 39 standard regulations from Wellmade scaffold standards.

The differences between BS1139 and EN 39 are the chemical composition. In the BS1139 scaffolding pipe stand, no need for aluminum elements in chemicals. While in the EN 39 scaffolding pipe standard, Aluminium elements are required more than 0.02%.

Both BS1139 and EN39 the scaffold standards are British standards. They give safety regulations and guidelines for both steel and aluminium scaffolding pipes.

According to the standard, BS1139 and EN 39 scaffold tubes are in 48mm diameter. You can find the following pipe wall thickness for the BS1139 and EN 39 standard scaffold tubes.
