Pressure Locked Grating

Smooth Surface, Architectural Grating

Pressure Locked metal bar grating from IKG is among the oldest and most versatile types of grating. Created by bonding together the metal bars under intense pressure without the use of heat or rivets, the process leaves clean, and uncluttered lines. The resulting architectural appearance is attractive for grillwork, screens, dividers and other applications where maximum passage of heat, light and air is desired. 

Pressure Locked metal bar grating incorporates tight-fitting, slotted bearing bars and cross bars, locked together. The permanent locking of the bars is accomplished by slotting the bearing bars with a wider ‘dovetail’ shape at the bottom of the slot. When the bars are pressed together under hydraulic pressure, the cross bar material is forced into the ‘dovetail’ shape of the bearing bar notch, forming a strong, ridged product.  

Available with close bar spacing to accommodate requirements for pedestrian comfort and safety,  Pressure Locked metal bar grating can fulfill many other architectural needs for special grating for a particular job.  

IKG provides several products that help cities comply with the Americans with Disabilities Act (ADA). Pressure Locked metal bar grating panels can be fabricated so that they satisfy the maximum ½-in. clear opening required by the ADA. These panels are excellent for pedestrian use and areas where high visibility is a concern.

What is the ADA? The Americans with Disabilities Act (ADA) became law in 1990. The ADA is a civil rights law that prohibits discrimination against individuals with disabilities in all areas of public life, including jobs, schools, transportation, and all public and private places that are open to the general public.

B – (P-19-4)

The standard B product is approved for all general purposes with bearing bars on 1-3/16-in. centers and cross bars on 4-in. centers.

D – (P-15-4)

The standard D product is for general purposes with bearing bars on 15/16-in. centers and cross bars on 4-in. centers for conditions where more surface area is required. 

F – (P-19-2)

The standard F product is for general purposes with bearing bars on 1-3/16-in. centers and cross bars on 2-in. centers for conditions where more surface area is required. 

CM4 – (P-11-4)

The CM4 close mesh product has bearing bars spaced 11/16 in. on center and cross bars spaced 4 in. on center. It provides a larger open area where more ventilation is required beneath the grating and satisfies the maximum ½-in. clear opening as required by the ADA, if bearing bars have 3/16-in. thickness. 

CM1 – (P-7-4)

The CM1 close mesh product has bearing bars spaced 7/16 in. on center and cross bars spaced 4 in. on center. Our closest spaced grating available, CM1 is ideal for pedestrian use where high visibility is a concern. It satisfies the maximum ½-in. clear opening as required by the ADA.
