Galvalume steel sheet is a type of steel that is coated with zinc for protection by an electroplating process. The galvanized layer is applied to cold rolled steel at low temperatures. So it is also known as cold galvanized steel.

Wire rod is a steel product in the form of long, straight, usually round rods, widely used in wire drawing, cold heading, and other industrial applications.

Wire rod is a rolled steel bar commonly used on construction sites, with diameters of 6, 8, 10, and 12 millimeters. It is mostly made of low carbon steel and is not commonly used as the main reinforcement in reinforced concrete structures. It is mostly used to make steel sleeves, and small diameters are used for "brick reinforcement" in brick concrete structures.

Carbon steel is the most common form of steel rebar (short for reinforcing bar or reinforcing steel). Rebar is commonly used as a tensioning device in reinforced concrete and reinforced masonry structures holding the concrete in compression

BS 4449: 2005 uses the term 'bar' for ribbed reinforcing steel. The terms 'rod' and 'wire' should be restricted to describe reinforcing steel in coil, or wire in reinforced concrete products.

A615 steel rebar has a rough, blue-grey finish with raised ribs throughout the bar. Designed for use in concrete reinforcement, rebar increases the tensile strength of concrete structures. ASTM A615 is the standard specification for deformed and plain carbon steel bars for concrete reinforcement.

Reinforcement bar grade in China is subject to the requirements of Chinese Standards GB1499.2-2018. According to the production process, we have hot-rolled steel bar (H) and cold rolled steel bar (C). The hot rolled steel bar is divided into plain round bar and ribbed bar.
