Specification
Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel’s recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes. Hot rolled steel is typically cheaper than cold rolled steel due to the fact that it is often manufactured without any delays in the process, and therefore the reheating of the steel is not required (as it is with cold rolled). When the steel cools off it will shrink slightly thus giving less control on the size and shape of the finished product when compared to cold rolled.
Uses: Hot rolled products like hot rolled steel bars are used in the welding and construction trades to make railroad tracks and I-beams, for example. Hot rolled steel is used in situations where precise shapes and tolerances are not required.

- Q: Can the steel sheets be easily formed into decorative panels?
- Yes, steel sheets can be easily formed into decorative panels.
- Q: What is the hardness of steel sheets?
- The hardness of steel sheets can vary depending on the specific grade and manufacturing process, but generally, steel sheets have a high level of hardness due to their composition and heat treatment.
- Q: How do you repair damaged steel sheets?
- To repair damaged steel sheets, the first step is to clean the area thoroughly, removing any dirt, rust, or debris. Then, using a grinder or sandpaper, smooth out the damaged area until the surface is even. Next, apply a suitable metal primer to the repaired area and let it dry. Finally, use a steel filler or epoxy putty to fill in any remaining gaps or imperfections. Once the filler is dry, sand it down to ensure a smooth finish, and paint the repaired area to match the surrounding steel sheets.
- Q: What is the difference between a galvanized and painted steel sheet?
- A galvanized steel sheet is one that has been coated with a layer of zinc to protect it from corrosion. This process, known as galvanization, involves immersing the steel sheet in a bath of molten zinc, which forms a bond with the underlying steel. This zinc coating acts as a sacrificial anode, meaning that it corrodes instead of the steel when exposed to elements such as moisture and oxygen. As a result, galvanized steel sheets have excellent corrosion resistance and can last for a long time in outdoor environments. On the other hand, a painted steel sheet is one that has been coated with a layer of paint to provide both aesthetic appeal and additional protection against corrosion. The paint acts as a barrier between the steel surface and the surrounding environment, preventing moisture and other corrosive substances from coming into direct contact with the steel. This helps to prolong the lifespan of the steel sheet and maintain its appearance. In terms of appearance, galvanized steel sheets have a characteristic silver-gray color due to the zinc coating, while painted steel sheets can come in a wide range of colors depending on the type of paint used. Galvanized steel sheets also have a textured surface due to the presence of the zinc coating, while painted steel sheets can have a smoother or textured finish depending on the application technique. Ultimately, the main difference between galvanized and painted steel sheets lies in the method of protection against corrosion. Galvanized steel relies on the sacrificial corrosion of zinc, while painted steel relies on the barrier effect of the paint. The choice between the two depends on factors such as the specific application, aesthetic requirements, and the level of corrosion resistance needed.
- Q: Do the steel sheets have any specific certifications?
- The quality and compliance of the steel sheets are ensured through specific certifications.
