304 stainless steel pipe is the most widely used foundational grade among austenitic stainless steel pipes. Renowned as the “universal stainless steel pipe” due to its excellent corrosion resistance, mechanical properties, and workability coupled with high cost-effectiveness, it caters to diverse applications ranging from residential decoration and food/medical sectors to industrial piping systems. It stands as the “mainstream benchmark product” in the stainless steel pipe market.

Galvanized welded pipe is a type of steel pipe manufactured through a welding process. It uses steel strips or plates as raw materials and is welded into shape using methods such as furnace welding or electric welding to form a black pipe (i.e., ungalvanized steel pipe). Subsequently, a zinc layer is coated on the pipe wall surface through hot-dip galvanizing or electro-galvanizing (cold galvanizing) processes. Hot-dip galvanizing has become the mainstream application due to its thicker zinc layer and better corrosion resistance. Its main classification is based on the different galvanizing methods, divided into hot-dip galvanized welded pipe and cold-dip galvanized welded pipe (electro-galvanized welded pipe), with hot-dip galvanized welded pipe being widely used due to its superior performance.

Galvanized seamless steel pipe is a corrosion-resistant steel pipe made by using seamless steel pipe as the base material and forming a zinc layer on its surface through a hot-dip galvanizing process.
This process involves pickling the steel pipe to remove surface oxides, followed by immersion in molten zinc, allowing the substrate and coating to bond and form a zinc-iron alloy layer, thereby significantly improving corrosion resistance.

Galvanized square pipe is a hollow square cross-section steel pipe with a square cross-section shape and size made from hot-rolled or cold-rolled galvanized strip steel or galvanized coil plate, which is formed by cold bending and then high-frequency welding. , or galvanized square rectangular pipes made by hot-dip galvanizing the pre-made cold-formed hollow steel pipes.

Galvanized rectangular tubes are hollow, long steel strips with a rectangular cross-section. They belong to the category of cold-formed hollow steel sections and are classified into two types based on the galvanizing method: hot-dip galvanizing and electro-galvanizing. Hot-dip galvanizing involves a high-temperature zinc layer, providing strong corrosion resistance and making it suitable for outdoor applications. Electro-galvanizing has a smooth surface but weaker corrosion resistance and is mostly used for indoor applications.

316 stainless steel tubing is a widely used premium grade within the austenitic stainless steel family. Due to the addition of molybdenum (Mo), it offers significant improvements in corrosion resistance, high-temperature stability, and mechanical properties compared to the base 304 stainless steel tubing.

Carbon steel square tube is a commonly used steel product and has the potential to be widely used. It is composed of carbon and iron alloys and plays an important role in different industrial fields. This paper will introduce the definition, characteristics, application fields and market prospects of carbon steel square pipe in detail.

Seamless pipe is a long steel strip with a hollow cross-section and no seams around it. There are more than 5,100 production plants under more than 1,850 companies in more than 110 countries producing seamless pipes in the world, of which more than 260 plants under more than 170 companies in 44 countries produce oil pipes.
