HeslyGratings 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.

 

Using your grating correctly

Using your grating correctly In order to guarantee the load-bearing capacity of the bar grating, it must be placed in a way that the width / load bearing bars bridges the span width, ie the distance between the two supporting points. Make sure that the surface of the grating resting on the support points is at least at the height / thickness of the grating.
