What Northstar Roofing does

Wanhao Paper Group (万豪纸业集团), operating under the label "OD官方版网站登录入口-OD(中国)", is a privately held Chinese specialty paper manufacturing conglomerate headquartered in Linqu County, Shandong Province. Founded in 1966 as the state-owned Linqu County Paper Mill and restructured into a joint-stock company in 1994, the group today comprises six entities across three core operating subsidiaries: Shandong Longde Composite Materials Technology Co. (山东龙德复合材料) focused on automotive and industrial filter paper; Linqu Yulong Paper Co. (临朐玉龙造纸) producing specialty, cultural, and packaging papers; and Linqu Paper Chemical Co. (临朐纸业化工) supplying papermaking additives. Total assets stand at 6.8 hundred million yuan, with 1,200 employees and a 420 mu (~280,000 sqm) headquarters complex at Huate Road 5311, Linqu County Economic Development Zone.

The group's core technology centers on specialty paper manufacturing, with particular depth in automotive filter media. Longde operates proprietary inclined wire forming and through-dry technology, German-imported VITS coating machines with sub-2-micron metering roll precision, and a German WK RTO waste gas recovery system. It holds 36 invention patents and 12 utility model patents, and has developed six product series of automotive filter paper meeting China's Guo VI (国Ⅵ) emission standards. Annual production capacity reaches 120,000 tons of machine-made paper across filter paper (10,000 tons/year), specialty papers, coated paper, cultural paper, household paper, and paper chemicals production lines.

The business model is direct B2B sales to manufacturers, organized by product category through dedicated sales teams. Pricing is quote-based on order volume, specifications, and customer requirements. Key customers include the major Chinese state-owned automakers (BAIC Foton, FAW, SAIC, Dongfeng, GAC) as main-engine supporting partners, global filtration leader Mann+Hummel Group under a May 2019 strategic agreement, and downstream packaging, food, and publishing customers (e.g., Hangzhou Dingzheng, Fujian Nanwang, China South Publishing & Media Group). The group exports to Southeast Asia, the Middle East, Europe, the Americas, and Australia, with Yulong covering 30+ Chinese provinces domestically.
