Pressure Locked Grating is made of two extruded bearing bars, locking them together. It’s process is different from swaged aluminum grating, it doesn’t need to be swaged , just need to pressure the bearing bars on both ends to make them locked tightly. Swage locked grating is strong and tight enough to hold on heavy things. Pressed grating is consisted of two flat bars, instead cross bars with flat bars. As all the flat bars are bearing bars, it is weighty but with good bearing strength. There are plenty types of bearing bars for pressure locked grating like 40*3, 40*5, 45*5, 50*5, 57*6, 65*5, 76*4.7 and other types. You can also require for serrated flat bars or plain flat bars for pressed grating.

Press lock grating is our newly designed product developed by HY Group, which is made of pre-punched bearing bars, pressed grating is a heavy duty bar grating. It requires a much great pressure for the machine. Pressed grating also has a more excellent strength than other gratings.
