Black pipe/tube
Black pipes are usually made of high-strength steel, which has the characteristics of corrosion resistance, pressure resistance, and tensile strength, ensuring the stability and reliability of the product.

            Black round tubes generally have higher strength and can withstand greater pressure and weight. For example, when used as a load-bearing structure in the construction field, they can stably support the weight of the building; when transporting high-pressure fluids in the industrial field, they can also withstand internal pressure without damage.
 
            Black square tube, also known as black square tube, is a common building material, usually made of hot-rolled or cold-drawn steel strip. Its surface is usually treated with rust prevention to prevent oxidation and corrosion.
 
            S350GD+Z is a galvanized steel coil made of medium carbon low alloy high strength structural steel. Its hardness range is usually between HRC25 - 40. Compared with S280GD+Z, it has lower hardness, but better plasticity and toughness. However, its wear resistance and fatigue resistance are relatively poor, and its machinability and welding performance are good.
 
            Galvanized round pipe is a round steel pipe that has been hot-dip galvanized. It has good corrosion resistance and can maintain stable performance in harsh environments. Due to its excellent characteristics and wide range of uses, galvanized round pipe has become an indispensable and important material in many industries.
 
            A36 A53 GradeB Galvanized steel pipe is a galvanized steel pipe that meets specific standards. Among them, A36 is a common carbon structural steel standard with good strength and toughness; A53 GradeB is a standard for seamless and welded steel pipes established by the American Society for Testing and Materials (ASTM). GradeB means that the grade of the steel pipe is B, which usually has higher quality and performance. This steel pipe is galvanized to form a layer of zinc coating on the surface, which can effectively prevent the steel pipe from rusting and corrosion and extend its service life.
