Introduction<\/h2>\n
Outdoor heavy industrial facilities such as thermal power plants, coal conveyor galleries, multi-layer factory platforms, and open-air industrial corridors face unique dual safety challenges: long-term outdoor wind and rain erosion, and frequent debris falling hazards on multi-level elevated structures. Traditional open bar grating, including serrated grating and non-slip bar grating, delivers excellent drainage and anti-slip performance but features fully hollow grid gaps. These open structures allow coal dust, gravel, maintenance tools, equipment parts, and industrial residues to fall from upper floors, causing equipment damage, operational failures, and serious personal safety accidents on lower working levels. Pure solid steel plates solve falling risks but suffer from poor drainage, severe rainwater accumulation, accelerated corrosion, and excessive structural weight, which increase building load pressure and maintenance costs.<\/div>\n
