A lattice can be made from either wood or metal, as long as the strips cross to form squares that leave approximately the same size diamond shaped voids between them.  A lattice may be used as a screen, a fence, or a support for climbing plants.  

There are also concepts such as lattice energy, lattice degeneration, and lattice multiplication.  There is also a lattice structure where the atoms are arranged so they form geometrical points in space in the shape of a lattice.

Before the advent of RADAR, to see adversaries as far away as possible, battleships had watch officers posted very high above the deck. In the WWI era until the twenties, US battleships had lattice masts with watch standers who could see over the horizon. These lattice-work masts evolved into the tripod style conning towers like the ones aboard the USS Arizona at the time of her destruction.

USS Idaho was a pre-Dreadnought style battleship equipped with lattice-masts.

USS New York (Arizona's sister) in the thirties. The tripod style conning towers contained spotters range finders, and fire control/direction equipment.  

The Japanese went a different direction, creating huge "pagoda" style conning towers for their older battleships like the Kongo, Fuso and Ise classes. Of course, after RADAR, those big Pagoda style conning towers made for solid RADAR returns.
