Changhai Composite Materials
Changhai manufactures glass-fibre products and composite materials.
Company identity and history
The Chinese site identifies 江苏长海复合材料股份有限公司. Its history marks company formation in 2000, while the English homepage displays 2002 as company establishment and uses varying English name forms. These differences remain unresolved, so this profile does not select a single founding year or invent a standardized English legal name.
Business and product context
The published business covers glass-fibre yarn and rovings, mats and composite-material products. Selection should identify reinforcement form, resin compatibility and the relevant grade document. The company publishes a contact address on Changhong East Road in Changzhou; it is recorded as a contact location rather than a confirmed headquarters label.
