What Is Steel Bar Grating?
Steel bar grating with high strength and firm structure is made from carbon steel, aluminum steel, or stainless steel. According to manufacturing methods, it can be divided into four types: welded, press-locked, swage-locked, and riveted gratings. Based on surface shapes, it can be categorized into smooth and serrated gratings. With various styles and sizes available, steel gratings are widely used in everyday applications such as stair treads, walkways, platforms, floors, various covers, wheeled equipment, security screens, heavy-duty constructions, and more.
Applications
  • Industrial Platforms: Walkways, operating platforms
  • Construction: Drain covers, trench covers
  • Municipal Engineering: Sewer covers, sidewalks
  • Power Plants: Maintenance platforms
  • Petrochemical Industry: Corrosion-resistant flooring

Surface Treatment of Steel Grating
1. Hot-dip galvanizing
Hot-dip galvanizing is usually carried out after the hemming is completed, which makes it highly corrosion-resistant and greatly extends its service life.
2. Painting
Spraying, painting or dipping according to the customer's special requirements.
Main Components of Metal Bar Grating
ComponentDescription
Span:Total span
Width:Panel width
Bearing Bars:Load carrying the main element
Bearing Bars Spacing:Measure from center-to-center of the bearing bars in 1/16″ increments. Standard spacing for industrial flooring is 19/16″(1-3/16″) in the center. Other popular spacings are 15/16″, 11/16″, 1/2″, and 7/16″ on center.
Bearing Bars Depth:Ranges from 3/4″ to 7″ depending on anticipated loads
Bearing Bars Thickness:Ranges from 1/8″ to 1/2″ depending on anticipated loads
Cross Bars:Used to secure the position of bearing bars
Cross Bar Spacing:Measured from center-to-center of cross bars in 1″ increments. Standard spacing is 4″ or 2″ on center.
