THE UNION IRON MILLS, Pittsburgh, Pa., Manufacturersof improved wrought iron Beams andGirders (patented). The great fall which has taken place in the prices ofIron, and especially in Beams used in the constructionof FIRE PROOF BUILDINGS, induces us to call the specialattention of Engineers, Architects, and Builders tothe undoubted advantages of now erecting Fire Proofstructures; and by reference to pages 52 & 54 of our Bookof Sections—which will be sent on application to thosecontemplating the erection of fire proof buildings—THECOST CAN BE ACCURATELY CALCULATED, thecost of Insurance avoided, and the serious losses and interruptionto business caused by fire; these and like considerationsfully justify any additional first cost. It isbelieved, that, were owners fully aware of the smalldifference which now exists between the use of Woodand Iron, in many cases the latter would be adopted.We shall be pleased to furnish estimates for all the Beamscomplete, for any specific structure, so that the differencein cost may at once be ascertained.
