With its claim to have produced more than one in three of all blades in operation in the world, Danish firm LM Windpower is the clear market leader in the blade industry.
Some of the independents produce blades to specifications of blade design firms or of big brands that don’t make blades in-house.
As an independent, Germany’s SGL Rotec manufactures exclusively to customers’ specifications.
The design is then matched to an optimum production process, in close cooperation with the customer. With its 20,000 square metre production site alongside a transport link to the Ochtum Harbour, SGL Rotec takes advantage of the direct connection to the Weser River, and specialises in very large rotor blades for use offshore.
The rest of the market is largely taken up by wind energy companies that make in-house blades, such as Vestas, Enercon, Suzlon, Siemens, Repower and Gamesa.
A significant manufacturer of rotor blades in Asia is Zhongfu Lianzhong Composite. It is part of the China Composites Group, itself a subsidiary of China Building Material Group Corporation. Zhongfu Lianzhong has 2,000 employees and is headquartered in Lianyungang city in Jiangsu province.
Zhongfu engages in the research and development, manufacture, and supply of rotor blades, pipes, tanks, cylinders, and high pressure pipes for clients in China, Argentina and internationally.
