Abstract
A method of producing torch-and-drill proof slabs, and their use in the construction of modular safe walls. The slabs are formed by casting a metal plate having one, planar side and an opposite side formed with a series of parallel, generally V-shaped recesses. The recesses are divided by elongated projections so that every sloping side-surface of a recess intersects with an upright side-surface of a respective projection along a ridge line. A series of elongated, springy V-shaped steel bars are made, having opposite pointed side-edges extending parallel to each other, at a distance somewhat larger than the distance between the facing ridge lines. The bars are forcibly wedged from above into the recesses so that the pointed edges become snapped-in between opposite ridge lines.
