Q & A

Steel profiles are crucial components in coastal protection and sea defense systems as they provide structural integrity and durability. These profiles are used in various applications such as retaining walls, breakwaters, and groynes, offering resistance against erosive forces caused by waves, tides, and currents. They effectively absorb and dissipate energy, preventing erosion and damage to coastal areas. Additionally, steel profiles can be easily installed and maintained, making them an efficient choice for enhancing the resilience of coastal regions to sea-level rise and extreme weather events.

The main differences between hot rolling and cold rolling of steel profiles are the temperature at which the rolling process takes place and the resulting mechanical properties of the steel. Hot rolling involves heating the steel above its recrystallization temperature and then passing it through a series of rollers to shape it into the desired profile. This process is carried out at high temperatures, typically above 1000 degrees Celsius. Hot rolling allows for faster production rates and is ideal for shaping large sections or long lengths of steel. It also results in a rougher surface finish and less precise dimensional accuracy compared to cold rolling. On the other hand, cold rolling is performed at room temperature or slightly below, typically between room temperature and 100 degrees Celsius. The steel is passed through rollers to shape it into the desired profile, but since it is not heated, the process requires more force. Cold rolling results in a smoother surface finish, improved dimensional accuracy, and tighter tolerances compared to hot rolling. It also enhances the mechanical properties of the steel, such as increased hardness and strength, due to work hardening during the cold rolling process. In summary, hot rolling is suitable for mass production of steel profiles with larger dimensions, while cold rolling is preferred for precision applications requiring better surface finish, dimensional accuracy, and enhanced mechanical properties.

Steel profiles are typically transported using trucks or flatbed trailers equipped with secure tie-down systems to prevent movement and ensure stability during transit. They are often loaded and unloaded using cranes or forklifts to minimize handling risks. When it comes to storage, steel profiles are stacked in an organized manner, using proper support and spacing to prevent deformation or damage. Warehouses or storage areas should have appropriate ventilation, protection from weather elements, and be free from any potential hazards that could compromise the integrity of the profiles. Additionally, it is crucial to follow safety guidelines and use protective gear when handling steel profiles to minimize the risk of accidents or injuries.
