SummaryShandong Longzhiyu Import and Export Co., Ltd. is identified as a Chinese manufacturer/factory in Shandong engaged in construction and decoration-related commercial activities. It has professional technical R&D capability, offers customization from samples and designs, and provides ODM and OEM services, but does not provide 3D software design, has no new products reported in the past year, and has no SDK. Production information indicates output of 30,000,000 square meters of ceiling tee grid and 7,200,000 square meters of gypsum ceiling tile annually, with fewer than five quality-control staff reported. The supplier has 13 years of export experience, self-operated import/export rights, and 90% export sales, but lacks in-stock, overseas warehouse, showroom, agent, or branch service capabilities. Financial records are indicated for 2021–2023, but the slices do not provide sufficient evidence to assess financial strength. No certification holdings or customer cases are documented.
