How to choose high-quality square steel pipes

First, what are square steel pipes: square steel pipes are a type of steel pipe, that is, square pipes. They are called square steel pipes together with rectangular pipes. They are made of strip steel after processing and are widely used in the construction field.

Second, how much does a square steel pipe cost per ton: As a building material, square steel pipes are widely used in machinery manufacturing, shipbuilding, steel structure engineering, power engineering, etc., and their prices are not cheap. So how much does a square steel pipe cost per ton? The price of square steel pipes in the market is not fixed and is mainly affected by the price of steel in the market. In addition, the production process, production standards, surface treatment process, use, specifications, wall thickness, etc. of square steel pipes will also affect their prices. The price of square steel pipes varies depending on the place of purchase, ranging from more than 5,000 yuan to 6,000 to 7,000 yuan per ton.

Third, how to choose high-quality square steel pipes: Square steel pipes are a kind of material commonly used in the industrial construction industry, with a large demand. There are many square steel pipe products on the market, and the quality varies. When choosing, you should pay attention to the selection method:

1. Look at the size: You can use a vernier gauge to simply measure whether the actual size is about one specification or smaller than the indicated size. Generally, there is not much difference in good square steel pipes; in addition, it should be noted that some inferior square steel pipes will deceive people's vision by smashing the mouth, so it is flat and elliptical when observed from the end face of the steel pipe surface, while the end face of the regular material should be circular.

2. Look at the performance: Square steel pipes have certain tensile and compressive properties, so we can also consider these aspects when choosing square steel pipes: tensile resistance is the basic performance of square steel pipes, and the greater the tensile strength, the better the performance of square steel pipes; compressive and bending properties should also be considered comprehensively.

3. Look at the surface quality: inferior square steel pipes are rolled with unqualified raw materials, so their surface quality is poor, often with defects such as scarring, and an overall rough feeling. Some small steel mills have a reddish surface color due to insufficient heating temperature and rolling speed; high-quality square steel pipes are of good quality, without obvious defects, and bright white.

4. Look at the packaging: regular square steel pipes are mostly packaged in large bundles when they leave the factory. The bundles of steel are hung with metal labels corresponding to the actual objects, indicating the manufacturer, steel grade, batch number, specification and inspection code, etc.; while small bundles (about ten bundles) or bulk packaging, square steel pipe products without metal labels and quality assurance certificates should be paid special attention.
