Engineer learning to retain old structural support

Usage examples of angle iron.

The first experiments were made with vessels of wood, but they eventually led to the construction of iron vessels upon a large scale and on an entirely new principle of construction, with angle iron ribs and wrought-iron sheathing plates.

The shelves themselves were constructed of steel I-beams and angle iron, riveted together to make a web of shelving strong enough to support thousands of tons: vast piles of tree-trunk-thick legbones, skulls the size of cars, massive slabs of stone matrix with bones still imbedded, awaiting the preparator's chisel.

Already onshore were orderly piles of angle iron, corrugated tin, lumber, and plywood.

To make it even more difficult, angle iron welded with sharpened rebar, saw blades and anything else sharp and metal that came to hand had been piled in front of the embankments and laced with concertina wire.

The railings were warped, and missing sections had been crudely patched with welded pipe, rebar, and angle iron.

The farmer had probably taken up the land here because there was a taxandrent reduction for those willing to be first in such places, isolated and dangerous, and the ten-foot-high fence of angle iron and barbed wire that surrounded the houses was supporting evidence.
