General Information About Metal Grating

Metal grating is a type of metal structure made by welding equally distanced bearing bars with cross bars. These steel bars intersect with each other perpendicularly to form a platform that looks similar to a grid. These structures are easily fabricated, and known for their strength and durability.

Metal grating is a key part of the industrial flooring and construction industry. It is used in fences, walkways, and platforms on job-sites and in support for walls and structures in construction. There are three sub-groups of metal grating: non-serrated grating, serrated grating, and expanded metal grating.

More Details About Each Metal Grating Type

  • 19W4 Serrated Grating

    Type 19W4 serrated bar grating has notches in the bearing bars. This provides traction for large automobiles and forklifts in environments with water and oil.

  • 19W4 Non-Serrated Grating

    Type 19W4 non-serrated grating has a smooth surface on its bearing bars and cross bars. It is used for areas of traffic with heavy automobiles and forklifts.

  • Expanded Metal Grating

    Expanded metal grating is sheets of metal cut and stretched to form a diamond shape pattern that is similar to a mesh net or web. The metal is never completely cut so it is able to retain its strength. Expanded metal grating can be used in construction to support materials in walls or structures.
