On June 3, the “Steel Frame Structure Suitable for Large-Span Four-Slope Roofs,” independently designed by Shanghai Zhengcheng Mechanical & Electrical Manufacturing Co., Ltd., a subsidiary of CP M&E GROUP, was officially granted a national utility model patent. This solution breaks through the traditional limits of span and precision in slope roof structures, with a focus on mathematical standardization and fully prefabricated processes, providing an efficient and innovative solution for large-scale building roof engineering. “Maintaining technological leadership” and “technology-centric” are core principles of CP M&E GROUP's management philosophy. Over the years, CP M&E GROUP has consistently driven technological innovation and breakthroughs, securing over a dozen new technology patents in 2025 across four key areas: prefabricated buildings, livestock engineering equipment, industrial safety devices, and robotics technology.

In the livestock engineering field, two core patents focus on efficient construction: prefabricated manure trench wall panels achieve rapid assembly of manure trenches through standardized components, reducing construction time by over 50%; prefabricated pig barn wall panels integrate insulation layers with bolted assembly designs, addressing the issue of cracking in traditional walls, and have been applied in multiple projects constructed by Shanghai Zhengcheng. The separable controller for livestock farm heating lamps achieves three breakthroughs through “separable design + intelligent voltage regulation algorithms”: seamless retrofitting, constant-temperature smooth regulation, and end-to-end digital management.

The industrial equipment sector has also achieved significant results. For fluid handling applications, the company has launched two submersible pump lifting devices: the model with linear guides supports 360° rotation and precise positioning, enhancing safety in deep well operations; the rotatable cantilever device, with its compact footprint and flexible operation, has become the preferred choice for wastewater treatment plant upgrades. Additionally, the tank interior inspection door employs an innovative three-axis hinge structure to achieve the effect of “the greater the pressure, the stronger the seal,” providing a new solution for safe maintenance of chemical storage tanks.

In the field of large-scale building structures, the large-span four-slope roof steel frame overcomes the limitations of traditional concrete beams, using modular steel truss combinations to support spans exceeding 40 meters, reducing construction costs by 30%. This technology has been successfully applied in the company's factory construction projects.

Over the past three decades, our team of professional engineers has established an innovative work chain covering R&D, manufacturing, and technology transfer. To date, we have obtained over 400 national patents, over 50 computer software copyrights, and have led or participated in the development of over ten industry standards. Our core technologies span areas such as steel structure intelligent assembly systems and livestock environment control software.

Recently, patented technologies such as the “large-span four-slope roof steel frame structure,” “prefabricated manure trench wall panels,” and “inspection doors installed inside storage tanks” have been successfully commercialized, providing technical support for related businesses. In the future, we will continue to increase investment in scientific and technological innovation, fully leverage the示范 and leading role of high-tech enterprises, and promote the development of modern agriculture toward the direction of “smart, efficient, green, and industrialized.”
