- Economic Development Zone, Zibo City, Shandong Province
Our factory is located close to quality raw perlite ore resources and supported by efficient land and sea logistics. With two fully automatic 1,200 C high-temperature expansion lines, we complete raw ore screening, expansion, modification, packaging and export customs clearance in one coordinated workflow.
We operate an independent quality inspection laboratory and test every batch for expansion ratio, bulk density, water absorption, particle size and purity. This helps overseas buyers receive stable products, clear documents and repeatable container supply.
Zhengshan established its manufacturing base in Zibo, Shandong, close to high-quality raw perlite resources.
Two full-automatic 1,200 C expansion lines support stable production of full-series perlite products.
Products are supplied to Japan, Korea and Southeast Asian markets including Vietnam, Malaysia, Indonesia, Thailand and the Philippines.
Perlite is a natural volcanic mineral. After instant expansion at 1,200 C, it forms a lightweight honeycomb structure with strong aeration, stable physical and chemical properties, sterilized performance, fire resistance and thermal insulation. Zhengshan develops this natural material into practical products for global growers, processors and engineering users.
Customers choose Zhengshan for direct factory supply, batch quality control, transparent logistics support and practical cooperation models. Our seedling-grade expanded perlite is sterilized, low-dust, hard-grained and resistant to powdering during mixing and long-term use, keeping drainage and aeration stable in high-temperature planting environments.
