Excellent performance that pays off in the long run

Dongfang (Guangzhou) Heavy Machinery Co. Ltd (DFHM) was founded in 2004 as a world-class manufacturer of large and complex components for nuclear power generation and petrochemical plants. The parent company, Dongfang Electric Corporation (DEC), is listed by the State Council, Assets Supervision and Administration Committee as one of the 53 key state-owned enterprises critical to China’s national security and economy. China is emphasizing nuclear power generation as one of the ways to reduce pollution from traditional coalfired power plants and to meet the country’s rapidly growing energy demands.

In 2006, the first construction phase of the manufacturing plant incorporated a Megadoor that would allow a 1 400 ton overhead crane to exit the building to unload large rough materials and load finished components onto transport ships. Phase two added an additional building and manufacturing capacity requiring seven doors ranging in size from 6 × 6 m (20’ × 20’) to 12.5 × 8 m (41’ × 26’). In addition, the owner requested the replacement of two bottom-rolling doors originally installed during phase one. These doors were only three-years old, but required constant maintenance and were a headache for everyone. Based on Megadoors’ performance in phase one, the owner specified Megadoors for these nine door openings too.

During the open bid process, the owner received a quotation from a local Chinese door company who “copied” the Megadoor and offered a price almost 50% lower than Megadoor. Obviously, this got the attention of the owner, who decided to investigate the alternative. The DFHM Facility Manager and his team independently visited another manufacturing plant where these local “copies” were installed to review the door system and meet with the end user. After the trip, the DFHM team concluded that high reliability and minimized maintenance cost were critical issues, and that Megadoor best matched the quality and reliability required in modern manufacturing facilities. They therefore ordered Megadoor.

Benefits

  • Quality and reliability – Megadoor is the world leader in supplying large door systems for heavy industry. Over the last 25 years, Megadoor has earned a reputation for quality products, performing reliably, in the world’s harshest environments. Megadoor offers the quality and reliability required in today’s modern manufacturing facilities in China.
  • Cost of ownership – The Megadoor is engineered for high-cycle usage by minimizing the amount of moving parts and wear items in the door system. Additionally, the majority of door components are manufactured from aluminum and PVC-coated polyester fabric, which eliminates corrosion costs and painting, making Megadoor the clear choice for marine environments.
  • Support – Megadoor is a part of ASSA ABLOY Entrance Solutions, which also includes the globally recognized Crawford brand for door and docking solutions. In China, Megadoor System 800 and System 1000 doors are manufactured at our plant in Kunshan China, near Shanghai.
