Grain Storage Warehouse — Dar es Salaam, Tanzania

Government grain storage warehouses in Tanzania must meet TBS (Tanzania Bureau of Standards) requirements and World Food Programme (WFP) specifications. ZhongSai provides standard-compliant material certificates, factory inspection reports, and fumigation treatment certificates. Our steel structure design considers grain loading, ventilation, moisture protection, and pest control to ensure safe long-term grain storage.

This project combines mechanical ventilation with natural ventilation. Ridge ventilators on the roof and louvers at the eaves create stack-effect natural ventilation. Above-floor duct ventilation systems with axial fans provide mechanical ventilation to ensure uniform temperature throughout the grain mass. 100mm rock wool sandwich panels provide thermal insulation to prevent condensation from temperature differences. Moisture barriers and under-floor ventilation ducts are installed.

Tanzania has a tropical savanna climate with distinct wet and dry seasons and high humidity variation. Steel surfaces are sandblasted to Sa2.5 grade, with a three-coat anti-corrosion system: zinc-rich epoxy primer (80μm) + micaceous iron oxide epoxy intermediate (100μm) + polyurethane topcoat (60μm), salt spray resistance ≥1000 hours. Anti-corrosion wax is applied to concealed areas, and bolts are hot-dip galvanized to ensure long-term rust resistance in humid environments.

Sea freight from Shenzhen to Dar es Salaam port takes approximately 28-35 days, and customs clearance after arrival typically takes 7-14 days. We recommend clients prepare import permits and TBS certification in advance, and tax exemption approval for government projects. ZhongSai provides complete packing lists, commercial invoices, certificates of origin (FORM A for tariff preferences), material certificates, and fumigation certificates to meet East African Community customs requirements.
