Louvers are typically crafted from durable materials such as aluminum, steel, or UPVC (Unplasticized Polyvinyl Chloride). Aluminum louvers are known for their lightweight, corrosion resistance, and ability to withstand various environmental conditions. Steel louvers offer exceptional strength and durability, making them suitable for demanding applications. UPVC louvers provide a durable option with high resistance to moisture, chemicals, and UV rays.
