Product Details
This product is a heavy-duty industrial portal frame suitable for various metallurgical, heavy machinery, and pressure equipment applications, covering a weight range from 10 tons to 270 tons. The main body is constructed from high-quality ZG230-450 (formerly ZG25) and ZG25Mn cast steel, ensuring stable mechanical properties and strong load-bearing capacity.
Multiple heat treatment processes—including normalizing, tempering, and stress-relieving heat treatment—significantly improve internal microstructure, effectively reduce residual stresses, and ensure dimensional stability and durability under high-load conditions.
Product quality is rigorously inspected according to the JB/T 5000 casting standard, with non-destructive testing meeting Grade 2 requirements to guarantee internal integrity and structural soundness.
Currently, these portal frames are successfully exported to India, South Korea, Pakistan, the Middle East, Southeast Asia, and beyond. They have also established long-term partnerships with numerous major domestic enterprises, earning market trust through reliable quality and service.
