Product Details

MCCB Highlights

Our commitment to excellence is evident in our meticulous selection of materials. We utilize high-quality high carbon steel and low carbon cold rolled steel to ensure the utmost durability and performance of our products. The main iron parts are crafted from iron base materials, specifically cold rolled steel 10 # steel, known for its exceptional strength and resilience. By employing A+ materials throughout our manufacturing process, we guarantee the reliability and longevity of our products.

Furthermore, our dedication to enhancing the properties of our materials is exemplified through the implementation of QPQ salt bath composite treatment. This advanced treatment significantly improves the wear resistance, corrosion resistance, and fatigue resistance of the metal surface, ensuring that our products can withstand the harshest operating conditions. As a result, the strength, mechanical life, and electrical life of our parts are enhanced by more than 10%, providing our customers with superior performance and peace of mind.

In summary, our unwavering commitment to utilizing top-quality materials and employing advanced treatments underscores our dedication to delivering products that exceed industry standards and meet the diverse needs of our customers.
