With over 20 years of experience in PVC extrusion and plastic product manufacturing, our team is dedicated to delivering durable, cost-effective, and fully customized PVC gravity louver solutions.
What is a PVC Gravity Louver?
A PVC gravity louver is a venting device designed to allow airflow while preventing rain, dust, and debris from entering a building. It operates automatically using gravity, meaning the louvers open when airflow pushes them and close when airflow stops, providing energy-free ventilation. These louvers are widely used in applications such as HVAC systems, industrial warehouses, commercial buildings, and residential areas.
Unlike traditional metal louvers, our PVC gravity louver products are lightweight, corrosion-resistant, and require minimal maintenance, making them ideal for long-term and cost-efficient installations.
Our Manufacturing Capabilities
At Shangyu, we integrate advanced twin-screw extrusion technology with strict quality control measures to manufacture our PVC gravity louver products. By extruding directly from PVC powder, we eliminate the granulation process, which:
Ensures uniform material consistency
Produces fully plastified and durable louvers
Reduces production costs by 15%+
Our company has independent design, engineering, QC, and sales departments, allowing us to manage every stage of production efficiently. We can produce customized PVC gravity louvers based on client drawings, samples, or specific performance requirements, including color, size, UV resistance, and flame retardancy.
