Jinan AIMI Automation Technology Co., Ltd. is based in China and lists aluminum grating products on Global Trade Plaza. The range includes plain grating, serrated grating, I-bar grating, and stair tread grating, all described as part of an aluminum grating series. The plain grating is formed by extrusion locking standard flat aluminum and aluminum rods, offering deformation resistance, weather corrosion resistance, heat dissipation, and maintenance-free service. Serrated grating adds a row of serrated anti-slip profiles on the flat aluminum side for enhanced anti-skid performance. I-bar grating uses I-shaped flat aluminum with non-slip grooves on the upper and lower surfaces, reducing weight per unit area while maintaining load capacity. Stair tread grating is cut from serrated grating to standard sizes per national standards, welded with flat aluminum into rectangular or other frameworks, and fixed with special lock clips.
