First, make sure you have cleaned the grill well. Place the ranch steaks on the grill on the diagonal, at about a 45-degree angle. Grill for about 4 minutes, pressing on the steak gently with a spatula occasionally. Rotate the steaks a quarter turn (90 degrees) so the angle of the steaks on the grill is about 45 degrees in the other direction. You are looking to create diamond patterns with the grill marks.  Flip and grill the steaks the same way, at a 45-degree angle to the grill bars. Then after a few minutes, turn the steaks another quarter turn (90 degrees) so that the grill marks form the same diamond crosshatch pattern on the other side.
