Frequently Asked Questions (FAQs)

Q1: What is the primary difference between expanded metal and perforated metal?

A1: Expanded metal, like Hexagonal Perforated Expanded Sheet Metal for Window Safety HJP-6535, is produced by slitting and stretching a solid sheet, creating a seamless, monolithic mesh. No material is lost in the process, and the strands are set at an angle, giving it a 3D texture and enhanced rigidity. Perforated metal, conversely, involves punching holes out of a sheet, meaning material is removed, and the holes are typically flat-edged. Expanded metal often offers superior strength-to-weight and anti-intrusion properties due to its inherent structure.

Q2: How does HJP-6535 contribute to energy efficiency?

A2: The precise hexagonal pattern and optional flattening of Hexagonal Perforated Expanded Sheet Metal for Window Safety HJP-6535 allow it to function as an effective sun screen. By reducing direct solar radiation entering a building, it significantly minimizes solar heat gain. This, in turn, reduces the workload on HVAC systems, leading to lower energy consumption for cooling and potential cost savings, especially in warmer climates. Its open nature also promotes natural ventilation.
