BEAMS & GIRDERS]

THE UNION IRON MILLS. Pittsburgh, Pa., Manufacturers of improved

wrought iron Beams and Girders (patented).

The great fall which has taken place in the prices of Iron, and

especially in Beams used in the construction of FIRE PROOF BUILDINGS,

induces us to call the special attention of Engineers, Architects, and

Builders to the undoubted advantages of now erecting Fire Proof

structures; and by reference to pages 52 & 54 of our Book of

Sections--which will be sent on application to those contemplating the

erection of fire proof buildings--THE COST CAN BE ACCURATELY

CALCULATED, the cost of Insurance avoided, and the serious losses and

interruption to business caused by fire; these and like considerations

fully justify any additional first cost. It is believed, that, were

owners fully aware of the small difference which now exists between

the use of Wood and Iron, in many cases the latter would be adopted.

We shall be pleased to furnish estimates for all the Beams complete,

for any specific structure, so that the difference in cost may at once

be ascertained. Address
