Common Applications

Heavy duty expanded metal grating is produced from aluminum, stainless or carbon steel sheet and plate which contains no joints or welds, as each sheet is a single piece of sturdy steel. Light weight and economical, expanded metal grating is ideal for use wherever a strong, durable lightweight surface is needed. It is the standard product specified by engineers and managers for use in:

  • Catwalks, ramps, stairs, platforms
  • Maintenance platforms
  • Elevated walkways
  • Infill panels
  • Mezzanines and heavy duty shelving
  • Truck-cab safety screens, vehicle flooring and transport protection
  • Cold storage
  • Ship and offshore rig flooring
  • Partitions where high security is important
  • Security platforms
  • Industrial stairs, window protection and doors

Generally, carbon steel expanded metal grating works well wherever a durable, cost-effective, non-slip surface is required.

The high percentage of open area, characteristic of expanded metal grating, allows snow, water and oil to drain off easily, thus maintaining the excellent slip-resistant surface. The same high percentage of open area also allows excellent passage of heat and light and contributes to walkway cleanliness. Where building maintenance and safety are important considerations, these features are outstanding.
