MBG PressLock Construction

On our computer controlled production lines, the bearing bars are notched and then locked with the cross bar at a very high pressure. The cross bar is inserted in the notches of the bearing bar and pres locked into a stable structure at a force of 500 tons.

This particular production method guarantees a uniform precision mesh size.

The edge of the PressLock grating is banded either with a T-shaped special section or flat bar. This process (i.e. where the banding is welded at right angles to and flush with the grating surface) is done with an automatic resistance welding process.

The Mesh Size on Press Lock Grating allows either bearing bars (T) or cross bars (F) to be spread in increments of 7 D16". This provides a great deal of flexibility in design. The 21 PL7 is the designation for bearing bar spacing (21 D16) and cross bar spacing (7 D16). The 7PL21 is the designation for bearing bar spacing (7 D16) and cross bar spacing (21 D16).
Cross Bars
At right angles to the bearing bars, the cross bars connect the bearing bars with one another in that they are pressed at the intersection points.
Bearing Bars
In parallel with one another, the bearing bars are the load carrying flat bars set out perpendicularly.

*Clear distance (a) between the bearing bar and the cross bar.
Banding Bars
Grating is usually banded all around by a flat bar, T-shaped section or U-shaped section.
Angle Collar
Angles can be welded on to one or several edges. Angle height should be at least the same as the bearing bar.
