According to the requirements of application departments, its products have their own functions, such as new generation awning materials, awning flexible light box advertising materials, inflatable structure materials, air duct materials, van roof materials, container bag materials and so on.
The variety of new tarpaulin materials has been greatly increased, and the technical performance and quality have also been obviously improved, which not only meets the needs of many domestic users, but also enters the international market.
20 1 1 year, China's tarpaulin industry is mainly concentrated in East China, with total assets accounting for 79.95% of the country's total assets, main business income accounting for 79.26% of the country's total income and total profits accounting for 73.52% of the country.
