270 mesh to micron: 53 µm (0.053 mm)
270 mesh is an opening of 53 microns, which is 0.053 mm or 0.00209 inch, on the ASTM E11 US standard sieve series. The nearest wedge wire equivalent is a 53 micron (0.053 mm) slot, because wedge wire is specified by its slot rather than a mesh count.

Equivalent wedge wire slot: 53 micron (0.053 mm)
Wedge wire is specified by its slot directly, so a wedge wire screen has no mesh count. Quote the slot in mm or microns.

What passes through 270 mesh
As a general reference on the Wentworth grade scale, particles smaller than 53 µm pass: clay. Real separation also depends on particle shape, the screen's open area and how the screen is loaded.
The wedge wire equivalent
A wedge wire screen is specified by its slot, so the equivalent is a 53 micron (0.053 mm) slot. Because the V-shaped wire widens behind the slot, particles that pass the face do not wedge in it. See mesh to micron and slot size and how to choose slot and open area.
