It requires virtually no maintenance and has an inherent anti-slippery property. Widely used in power plant, chemical plant, oil refinery, iron and steel works, paper mill, food processing plant, pharmaceutical manufacture, sewage treatment plant, civil engineer projects and other areas, welded steel bar grating is the most popular of all grating types due to its strength, cost efficiency and ease of installation.
