Bearing Bar

1.Louver Steel Grating

Louver grating is a special type of metal grating constructed with angled horizontal louver cross bars, which are pressed or welded into vertical bearing bars at a preset angle. This unique design delivers visual screening effect while allowing unobstructed airflow, making it an optimal option for projects requiring a balance of privacy, ventilation and aesthetics.

Different from conventional bar grating with cross bars perpendicular to bearing bars, louver grating adopts inclined cross bars. Louver steel grating is a special steel grating designed for excellent ventilation, effective sun shading and modern appearance.
