There are many manufacturers producing scaffold steel pipes with uneven quality. It is very important to make the right choice. After all, the quality of scaffolding steel pipe will directly affect the safety of construction workers. Therefore, when purchasing scaffolding steel pipes, we need to know how to distinguish high-quality and inferior scaffolding steel pipes.
(1) Inferior scaffolding steel pipes are made of uneven materials with many impurities, resulting in low steel density and the size out of tolerance seriously.
(2) Inferior scaffolding steel pipes are prone to occur scars.
(3) Inferior scaffolding steel pipes are prone to have cracks.
(4) There is no metallic luster on inferior scaffolding steel pipes.
(5) The surface of inferior scaffolding steel pipe is not handled with any anti-rust treatment, which is easy to rust and be damaged, thus affecting the use.
(6) Inferior scaffolding steel pipes do not reach the standard in strength with poor bearing capacity. They are easy to crack or bend.
As one of professional china steel pipe suppliers, let us introduce some points of high-quality scaffold steel pipes.
(1) High-quality scaffolding steel pipes are made of high-quality materials with uniform composition. High tonnage of the cold shear can make smooth and tidy surface of cutting end.
(2) High-quality scaffolding steel pipes have higher strength and are not easy to bend, crack or be damaged.
(3) High-quality scaffolding steel pipes have small size error, standard specifications and heavy weight.
(4) High-quality scaffolding steel pipes have passed the test with testing reports and product certificates.
(5) High-quality scaffolding steel pipes are hot-dip galvanized with anti-corrosion and rust-proof treatment. They have better durability. Good scaffolding steel pipes can be generally used for more than 15 years.
