Pressure Locked Grating is often desired because of its neat appearance, smooth clean
lines, durability, and its excellent lateral support. Permanent
locking is achieved by hydraulically pressing two
closely-toleranced slotted bars together. These gratings offer more
flexibility in design than any other grating type.
HeslyGrating offers two distinct types of Pressure Locked Gratings which are
identified by their method of assembly. Manufactured without the
introduction of heat or riveting, these gratings provide a finished
product with attractive architectural lines. This pleasing
appearance makes Pressure Locked Gratings ideal candidates for
architectural and ornamental applications such as grilles, screens
and fences. Additionally, pressure locked methods of manufacturing
allow for the production of close mesh gratings with minimal open
area. Pressure Locked Gratings with bearing bars spaced at 11/16"
and 7/16" on center conform with the rigid spacing requirements of
the Americans with Disabilities Act (ADA). These products are
commonly installed at the entrance to public buildings where
concerns of pedestrian traffic and high heeled shoes coincide with
needs for ventilation and drainage.
HESLY Pressure Locked Gratings are available in aluminum, carbon
steel, galvanized steel, and stainless steel.
