What are the main application areas of weather-resistant steel pipes?

Weather-resistant steel pipes are widely used in many industrial fields due to their excellent resistance to atmospheric corrosion (no surface treatment is required for long-term use). In the construction field, they are often used for exterior walls, roofs and structural parts (such as doors and windows), which can resist climate change and pollution erosion, extend the life of buildings and have decorative properties; the use of weather-resistant steel pipes in the field of engineering machinery (bridges, elevated steel structures, etc.) can cope with harsh outdoor environments and prevent equipment damage caused by corrosion; the use of weather-resistant steel pipes in the transportation field (highway/railway bridges, tunnel guardrails, etc.) effectively resists wind, rain and snow corrosion and ensures the safety of facilities. In addition, in the petrochemical industry, its chemical corrosion resistance makes it an ideal material for equipment such as pipelines and storage tanks (such as compressive strength ≥ 50MPa).
