Products Description
The correct choice of billet type, section shape, size and weight are of great significance to 09CuPTiRE-B weathering steel rolling production. Steel rolling production has certain technical requirements for raw materials, such as steel type, section shape, size, weight, and surface quality.

The consideration of these technical requirements is necessary to ensure the quality of steel. It should also be specifically considered when determining and selecting the blank. The 09CuPTiRE-B weathering rolling method can be divided into cold rolling and hot rolling according to the rolling temperature.

Products application
China TB/T 1979 09CuPTiRE-B weather resistant steel plate is a high-performance structural steel developed to provide excellent resistance to atmospheric corrosion. By adding a small amount of alloying elements such as copper (Cu), phosphorus (P), titanium (Ti), and rare earth (RE), this steel forms a dense and stable protective rust layer on its surface, which significantly reduces corrosion rate and extends service life compared to ordinary carbon steel.
09CuPTiRE-B steel plate is widely used in vehicles, bridges, transmission towers, containers, construction machinery, and railway rolling stock, where long-term exposure to the atmosphere is common. Its superior mechanical properties - including good toughness, weldability, formability, and fatigue resistance - make it an ideal material for structures that demand both durability and aesthetic appeal.
In addition, this steel's self-protecting rust appearance offers a natural, artistic look, making it also suitable for architectural applications, such as façades, outdoor sculptures, and landscaping projects. By reducing the need for painting and maintenance, 09CuPTiRE-B steel helps save long-term costs and supports sustainable construction practices.
