Hot-dipped galvanized round bars are highly suitable for various processing techniques. However, it is important to note that welding, torching, or abrasive sawing of galvanized steel should be avoided without proper protection and adequate ventilation. Galvanized round bars are typically made from A36 hot rolled steel or mild steel and undergo a molten zinc coating process (ASTM A123). The galvanization process can be identified by the crystallization pattern, often referred to as \"spangle,\" on the material\'s surface. Galvanized round bars have a semi-rough surface with dull edges and may have slight variations in dimensions along their length. They provide excellent corrosion resistance, making them ideal for outdoor use or environments exposed to harsh conditions. Common applications for galvanized round bars include hinges, railing systems, and ground stakes.

Galvanized Rebar

Rebar, commonly known as hot rolled ribbed bar, is a type of steel bar. The grade of ordinary hot rolled steel bar is determined by its minimum yield point and is denoted by HRB (Hot Rolled Bar) followed by a numerical grade. The letters H, R, and B represent hot rolled, ribbed, and bars respectively. Rebar can be classified into different categories based on its strength, such as HRB300E, HRB400E, HRB500E, HRB600E, etc. The thread specification range for rebar is typically 6-50mm. Commonly used sizes include 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm, 28mm, 32mm, 36mm, 40mm, and so on. The national allowable deviation for rebar is as follows: ±7% for diameters 6-12mm, ±5% for diameters 14-20mm, and ±4% for diameters 22-50mm. Rebar is commonly available in fixed lengths of 9m and 12m. The 9m length threaded rebar is primarily used for normal road construction, while the 12m length threaded rebar is mainly used for bridge construction.

Galvanized Square Bar

A square rod is a solid metal rod with a square cross-section. It is typically made from general-purpose steel, which offers excellent formability and weldability. To prevent corrosion and rust, the surface of the square rod is coated with a protective layer of zinc. Galvanized square rods, with this protective coating, have a longer lifespan and require less maintenance compared to non-galvanized rods. As a result, they can contribute to slightly lower maintenance and repair costs.
