Expanded Metal Grille – AISI 304

Corrosion-Resistant Protection with Maximum Air Permeability

This stainless steel expanded metal mesh was specifically developed for use in weather protection grilles. In such applications, protective performance, air permeability, and durability are equally critical. Manufactured from a single sheet of material, it results in a robust expanded metal mesh without weld spots or joints. This ensures high stability while maintaining a low weight. The square-mesh structure of the expanded metal grid provides an open area of approximately 82%. This promotes efficient airflow while offering reliable protection against leaves, foreign objects, and mechanical impacts. The technical design is based on 1.4301 stainless steel with precisely defined mesh dimensions.

In the outdoor areas of ventilation and air conditioning systems, moisture, weather conditions, and contamination place high demands on protective grilles. Expanded stainless steel offers a permanently corrosion-resistant solution here and helps reduce maintenance costs and downtime.
