Scaffold steel pipe, generally we call it scaffolding pipe, is a special term for people in construction or construction. Scaffold steel pipe can play different roles on construction sites and construction sites. In order to facilitate the decoration and construction of higher floors, it is impossible to In the place of direct construction, scaffold steel pipes can also provide protection for construction workers and roadside pedestrians, as well as maintenance of peripheral network and high-altitude installation and construction.
How to choose scaffold steel pipes?
1. Characteristics of high-quality scaffold steel pipes
NO.1 high quality material
High-quality scaffold steel pipes are made of high-quality materials with uniform composition, high tonnage of cold shears, and smooth and tidy cutting end faces.
NO.2 is stronger
High-quality scaffold steel pipes are stronger and less prone to bending, cracking or damage.
NO.3 Small size error
High-quality scaffold steel pipes have small size errors, standard specifications and heavy weight.
NO.4 There is a test report
The high-quality scaffold steel pipe has passed the test, and has the test report and product certificate. This is the most important point. When purchasing, it is best to ask the manufacturer to provide relevant reports to ensure that the product meets the requirements.
NO.5 Hot dip galvanizing
High-quality scaffold steel pipes will be hot-dip galvanized anti-corrosion and anti-rust treatment, and have better durability. Generally, good steel pipes can be used for more than 15 years.
NO.6 Trademark and printing

2. Characteristics of inferior scaffold steel pipes
NO.1 uneven material
Inferior steel pipes have uneven material, many impurities, low density of steel, and serious oversize, so when purchasing, it can be weighed and checked without a vernier caliper;
NO.2 prone to scarring
Inferior scaffold steel pipes are prone to scarring on the surface. This is mainly due to the use of inferior materials and the simple equipment of the manufacturer, which is easy to stick to steel, and is prone to scarring after rolling;
NO.3 prone to cracks
Inferior scaffold steel pipes are prone to cracks. The reason is that the billet is adobe, and the adobe has many pores. During the cooling process, due to the effect of thermal stress, cracks occur, and cracks occur after rolling.
NO.4 No metallic luster
Inferior scaffold steel pipes have no metallic luster. There are two reasons for the light red or pig iron-like color. One is that the billet is adobe. The second is that the rolling temperature of fake and inferior materials is not standard, and their steel temperature is measured visually, so that the rolling cannot be carried out according to the specified austenite area, and the performance of the steel will naturally fail to meet the standard.
NO.5 easy to rust
The surface of the inferior steel pipe is not treated with any anti-rust treatment, which is easy to rust and damage, which affects the use.
NO.6 Strength is not up to standard
Inferior scaffold steel pipes have substandard strength, poor bearing capacity, and are prone to cracking or bending. It is recommended to pay attention to the strength test of the product when purchasing.
NO.7 Second-hand steel pipe recycling
Some of the low-quality steel pipes are recycled second-hand steel pipes and re-processed to make them shoddy. The price of this kind of steel pipe is often very cheap, so if you buy it, don’t try to be cheap. It’s easy to accidentally buy low-quality steel pipes.
