Square rectangular pipe is a term for square and rectangular pipes, which refers to steel pipes with equal or unequal side lengths.

Spiral pipe, also known as spiral steel pipe or spiral welded pipe, is made of low carbon structural steel or low alloy structural steel strip rolled into a pipe billet at a certain angle of the spiral line (called the forming angle) and then the pipe seam is welded together, which can produce large diameter steel pipes from narrower strips of steel.
Spiral pipes are mainly used for oil and gas transmission pipelines, and their specifications are expressed in terms of outer diameter * wall thickness. Spiral pipe has single-sided welded and double-sided welded. The welded pipe should ensure that the hydraulic test, tensile strength of the weld seam and cold bending performance meet the requirements.
Spiral pipes are mainly used in water supply engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation and urban construction, and are one of the twenty key products developed in China. For liquid conveying: water supply, drainage, sewage treatment works, mud transport, marine water transport. For gas transportation: gas, steam, liquefied petroleum gas. For structural use: piling pipes, bridges, docks, roads, building structures, marine piling pipes, etc.

Electro galvanized wire, also called cold galvanized wire, is a kind of galvanized wire by using electro galvanizing process. Electro galvanization is a process to apply a layer of zinc to steel wire by electroplating. The zinc layer is thinner than that of hot-dipped GI wires. It has features like strong flexibility, great plasticity, good corrosion resistance, etc. The making process is shown below:

Steel rod coil (Low carbon steel)- pre-treatment – wire drawing – annealing – pickling – rust removing – cold galvanizing – wire coiling – quality control – packaging for sale

​Hot-dip galvanized steel wire has a thick zinc coating, excellent corrosion resistance and high tensile strength. It is widely used in construction, tying wires, making wire mesh or fences or nets, handicrafts, etc.

Wire rods are mainly used as blanks for wire drawing, and can also be directly used as building materials and processed into mechanical parts.
Wire rod, also known as wire rod, usually refers to small diameter round steel in coils. The diameter of the wire rod is in the range of 5-19 mm (usually 6-9 mm), and its lower limit is the minimum size of the hot rolled steel section.
Wire rods are round steel with relatively small diameter. The commodity form is supplied in coils. On the construction site, the common ones are those with diameters of 6, 8, 10 and 12 mm, most of which are low carbon steel. Generally, they are not used for the main reinforcement of reinforced concrete structures, but are mainly used for making reinforcement sleeves. There are also small diameter "brick reinforcement" used in brick concrete structures.
