expanded metal grating catwalkGrating is heavy duty expanded metal produced from carbon steel sheet and plate which contains no joints or welds, as each sheet is a single piece of sturdy steel. Lightweight 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 for use in catwalks, ramps, stairs, platforms, heavy duty shelving, truck-cab safety screens, ship and off-shore rig flooring and in partitions where high security is important. 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.

Advantages:

  • Anti-slipping surface offers great walking safety.
  • Open surface avoids dirt and grease accumulation.
  • Minimum fire prevention cost.
  • Low maintenance cost.
  • Facilitates handling & installation.
  • Lower cost compared to traditional bar gratings

Applications:

  • Mezzanines
  • Maintenance platforms
  • Elevated walkways
  • Ramps
  • Security platforms
  • Transport protection
  • Industrial stairs
  • Doors
  • Window protection
  • Cold storage
  • Vehicle flooring
