Hot Rolled Mild Steel Coils

Hot-rolled mild steel coils are continuous strips of low-carbon steel shaped above recrystallization temperature, then wound into coils for efficient transport and downstream processing. They feature a characteristic scaled surface finish and slightly broader dimensional tolerances compared to cold-rolled alternatives, but deliver excellent formability, reliable weldability, and competitive cost; making them one of the most widely used raw materials in construction and manufacturing alike.

From structural frameworks and industrial buildings to fabricated components and formed parts, hot-rolled coils serve as the starting point for a broad range of builds. As a trusted steel supplier in the Philippines, Metal Exponents maintains ready inventory across all major grades, backed by the technical knowledge to help you select the right material for your project requirements.
