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.
Black square tubes are generally made of high-quality carbon steel, which has good strength and toughness. Surface treatment: galvanizing, painting and other surface treatments can be performed to increase its corrosion resistance.
Black special-shaped tubes are usually made of high-strength steel, which has the characteristics of corrosion resistance, pressure resistance, and tensile resistance, ensuring the stability and reliability of the product.
Black seamless pipe is significantly stronger than pipe made from ordinary steel and can generally withstand greater external forces. This high strength makes it the material of choice for high pressure, high strength and weight load applications.
Black carbon steel pipes have high tensile strength and yield strength, can withstand large external forces, and can stably support and transmit forces in building structures, such as used in building frames, columns, beams and other parts.
