Dovetail Pressure Locked Grating an Alternative of Close Grating

Dovetail pressure locked grating refers to inserting punched bearing and cross bars into an "egg crate" manner and deforming rectangular cross bars under hydraulic pressure. It gives attractive architectural appearance and makes them ideal candidates for ornamental applications like fences and handrails.

Close mesh grating
Spacing between bearing bars affects the traffic of wheel chair and high heels. Dovetail pressure locked grating allows for production close mesh grating with bearing bars spaced at 11/16" and 7/16". It is proved that the spacing will reject high heeled shoes and conform to ADA (Americans with Disabilities Act).

Materials:

• Mild carbon steel in ASTM A-1011;
• 6000 series aluminum;
• 300 series stainless steels.

Spacing:

• Standard spacing:
  Bearing bars: 1-3/16" O.C. with cross bars at 4" O.C.
• Special spacing:
  Bearing bars: 1-3/16" O.C. with cross bars at 2" O.C.
  Bearing bars: 15/16" O.C. with cross bars at 4" O.C.
  Bearing bars: 15/16" O.C. with cross bars at 2" O.C.
• ADA spacing:
  Bearing bars: 11/16" O.C. with cross bars at 2" O.C.
  Bearing bars: 11/16" O.C. with cross bars at 4" O.C.
  Bearing bars: 7/16" O.C. with cross bars at 2" O.C.
  Bearing bars: 7/16" O.C. with cross bars at 4" O.C.
• Customized bearing bar spacing:
  Tailor-made bearing bar spacing can be manufactured for special purposes (2" or 4" cross bar centers should be maintained).

Applications:

• Fencing
• Security screens
• Truck grilles
• Trench grating
• Ornament grill
• Stage flooring
• Stair treads
