Import Expanded Metal Ventilation Screen/Vent S — Buy in wholesale FOB from Supplier in China

The Expanded Metal Ventilation Screen/Vent S is a reinforced sheet panel of expanded metal mesh, permanently enclosed in a heavy-duty steel frame designed for airflow control and physical protection. The mesh is formed by slitting and stretching a single sheet of metal, creating uniform diamond-shaped openings that maintain structural integrity while allowing air passage. The frame is typically made from 1.5mm to 2.0mm thick carbon steel, welded at corners for rigidity, and sized to fit standard exhaust pipe openings of 150mm to 300mm diameter.

The base material is low carbon steel with a hot-dipped galvanized finish, providing corrosion resistance suitable for outdoor exhaust environments. The expanded mesh pattern has a standard opening size range of 6mm to 12mm, with a thickness of 0.8mm to 1.2mm, typical for ventilation applications. Surface treatment is applied after forming to ensure even coating coverage, minimizing rust risk in humid or saline conditions. This product is not coated with PVC or paint, as those would obstruct airflow or degrade under high temperatures.

This screen is primarily purchased by HVAC installers, boiler manufacturers, and industrial equipment integrators who require passive airflow control in furnace, water heater, or exhaust duct systems. Buyers often source it in batches of 50 to 500 units per order, depending on project scale. Standard packaging is bulk-packed in cardboard boxes with foam inserts to prevent deformation during shipping. Trade terms are typically FOB Shanghai or CNF to major ports, with lead times of 15 to 25 days after order confirmation.

Jun-en Metal Mesh (Kunshan) Co., Ltd. operates from Kunshan, Jiangsu Province, with a focus on manufacturing expanded metal products for industrial ventilation and filtration markets. The company is registered as a harbor-tier supplier, indicating verified business registration and production capability. The listing shows no public response rate or average response time, suggesting limited direct buyer engagement through the platform. No claims are made about factory size, workforce, or export history beyond the product offering.

The supplier does not provide details on years in operation, certifications, or client list. There is no mention of ISO, CE, or other quality management systems. Production appears to be centered on standard expanded metal forms, with custom sizing available on request. The absence of response metrics and detailed profile data suggests this supplier operates primarily through catalog listings rather than active sales outreach.
