Our Advantages in Processing Lembar baja rol panas
High Temperature Processing
Manufacturing at temperatures exceeding 1,700°F enables optimal material flow and malleability, resulting in consistent thickness throughout the sheet and superior structural integrity compared to cold-rolled alternatives.
Efficient Rolling Process
Continuous rolling operation allows for high-volume production with minimal production steps, reducing manufacturing time and costs while maintaining precise dimensional control during the forming process.
Simplified Surface Finishing
The hot rolling process naturally creates a workable mill scale surface finish that requires minimal post-processing, making it ideal for applications where exact surface smoothness is not critical.
