Wire rod is a rolled steel product (alloy or non-alloy), manufactured from a semi-finished steel with a rectangular, rounded, hexagonal or squared shape. Especially, fine cross-sections are reached by sequent cold drawing. Wire rod is wrapped around into the coils and also carried in this form.

Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross section is round, sometimes square with rounded corners. Including plain round reinforcement, ribbed reinforcement and twisted reinforcement. Reinforcement for reinforced concrete refers to straight or coiled steel used for reinforcement of reinforced concrete.

Round steel belongs to carbon structural steel for construction and machinery, while square steel belongs to carbon structural steel for machinery. Both of them are simple section steel, and their section shapes are respectively round and square. Low carbon is mainly used for drawing wire, forging rivets, bolts, nuts and other metal products of raw materials. Medium carbon round steel and square steel are generally used to make mechanical structural parts.

Stainless steel round steel belongs to a class of long wood, and belongs to a class of bar, the so-called stainless steel round steel refers to a uniform circular cross-section of long wood, generally about four meters long. It can be divided into light circles and black rods. The so-called light circle refers to the smooth surface and comes from the quasi-rolling treatment; The so-called black rod refers to the black and thick surface and is directly hot-rolled.

Tee is also known as tee or tee pipe fittings, tee joints, etc. Mainly used to change the direction of the fluid, used in the main pipe to branch pipe. Can be classified by pipe size. Generally made of carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon, pvc and other materials.
