Stainless steel pipes: Corrosion-resistant, sanitary fluid-grade pipes and high-end engineering-grade pipes

Stainless steel pipes are hollow tubular steel products made from stainless steel material with chromium, nickel, molybdenum, and other alloying elements as the core, through hot rolling, cold rolling, welding, and precision forming processes. Compared to ordinary carbon steel pipes, stainless steel pipes completely solve industry pain points such as rust, corrosion, leakage, and secondary pollution, possessing advantages such as acid and alkali resistance, salt spray resistance, hygiene and non-toxicity, high temperature resistance

Color-coated steel sheet: Color-coated protective sheet material for steel structure roofs and walls and prefabricated buildings.

Color-coated steel sheet, also known as pre-coated steel plate, is a colored metal sheet made from hot-dip galvanized or aluminized zinc-coated steel sheets as the base material. After degreasing and phosphating pretreatment, a high-performance organic coating is applied to the surface, followed by high-temperature baking and curing. Color-coated steel sheet combines the structural strength of steel, the rust-proof performance of the galvanized layer, and the weather-resistant and decorative properties of the organic coating.

Carbon steel pipes: a universal core pipe material for fluid transportation and steel structure engineering.

Carbon steel pipe, also known as carbon fiber pipe, is a hollow-section steel pipe made from ordinary carbon structural steel through processes such as hot rolling, cold rolling, welding, and extrusion. The pipe is primarily composed of iron and carbon, without the addition of large amounts of alloying elements, retaining the core characteristics of carbon steel: stable performance, high plasticity, cost-effectiveness, and ease of processing and welding.

Color-coated coils: the core coil substrate for prefabricated buildings and color deep processing.

Color-coated steel coil, also known as color-coated steel coil, is a type of colored, anti-corrosion sheet made from hot-dip galvanized or zinc-coated steel coils. After degreasing, passivation, and chemical pretreatment, it is coated with organic paint using a continuous roller coating process and cured at high temperatures.
