Boiler Plate vs. Mild Steel: Why it Matters?

Boiler & PV Steel

Engineered specifically to withstand internal pressure and thermal expansion. Must pass rigorous testing and certification.

Structural Mild Steel

Used for general construction and fabrication where internal pressure is not a concern. Cost-effective for frames and supports.

Our Value-Added Services
