Show INCREASING ORDERS for COPPER I The following article from the Engineering En-gineering and Mining Journal, writ-ton writ-ton by A. B. Keith, gives an indlca-t:on indlca-t:on of the demand that will be shown for copper when it fully re-elvers re-elvers jits place in the industrial world : The Anaconda Copper Mining Co. has recently received its first order ! for copper shingles and from the number of inquiries being made enthusiasm en-thusiasm is running high as to the outlook for this venture of the company. com-pany. John Gillie, manager of Anaconda's Ana-conda's mines, in an address to the board of directors of the Butte Cham , Iber of Commerce, said that if the 1 1 market for these shingles measured 1 up to what they expected, half of the copper production of the whole coun-', coun-', try would be utilized in their manu-' manu-' facture. Formal announcement was made that the Anaconda now is in ! the market and is ready to supply ;ihe trade with either copper or zinc i ! shingles. ! Harold Blake, superintendent of (the foundry department of the Washoe Was-hoe smelters, in the course of an ad-: ad-: dress to the chamber, submitted interesting in-teresting figures pertaining to this j latest product of the Anaconda, stating stat-ing that the initial cost of copper i shingles over wodden was only about twice that for the wooden article, but when it was taken into conslder-jation conslder-jation that the life of the wooden shingle averaged only about tne or eleven years, while that of the copper cop-per was 100 years, or really as long as the foundation of the building en- dured. the material advantage in fa-, fa-, vor of the metal shingle was obvi- ous. Again Mr. Blake pointed out that in case of a fire there was no salvage value whatever to a wooden , shingle whereas it was 60 per cent for the copper shingle, represented j by the value of the metal. In the case l : of slate, asbestor or tile, the copper 'Single had a material advantage in the first cost, he said, and further, l j laying of copper shingles required j no particular skill and twice the area i could be covered in a day than with i the wooden shingle. Against this the , service of a skilled artisan was required re-quired when roofing of slate, asbestos asbes-tos or tile was to be laid. This copper shingle which is of 9-oz 9-oz sheeting, makes a roofing weigh-1 weigh-1 ing only 84 pounds to the square i 100 sq. feet. 3 in place, and is prob- ably the lightest substantial mater- al which may be employed for foof-i foof-i ing purposes. This weight compares with 600 lbs. for Johns-Manville, Col or or Blend asbestos; 750 to 1000 lbs for slate and 1.200 to 2,000 lbs. for I j tile. In the matter of roof trussing and lesser weight of the copper will J I make for considerable economy in I construction costs. The copper shln-jgle shln-jgle is not applicable to flat roofs, he Jjsald, but to meet the need the Ana- conda is producing a copper sheet, 1 1 with a tinned edge to permit of sol-j sol-j dering. The duplicate of the copper j shingle is being manufactured in I zinc, the initial cost of which is on-;ly on-;ly 15 per cent over the wooden shin- gle, and when the latter has been I, painted or stained, this margin is j further reduced. The company also j plans to make sidings for bungalows, 5 1 buildings, warehouses and in fact, ' for any sort of construction with the Jlsame argument as to durability ap- plying as pertains to the metal roof- ing. expedition in building and a re-J re-J duclion of the fire hazards. Through a process of exldotlon, S the company's metallurgists have I achieved some very skillful results. enabling the fixing of a coolor rang- ing from a very dark green to a brownish red. with the added qual-J qual-J ity that this variation of hues can J lie vnrnjshed by scrubbing the met ( with a solution of salamoniac, which will leave the sheeting the beauti- ful green color so characteristic of i copper roofs observed near the sea 0 coast. ?! The new shingles are IS Inches long by 6 inches wide and will be laid the long way horizontally. The J ' 9-nz. material Is recommended by the Anaconda for copper roofing, :and with the shingles come copper Si nails and such roofing auxiliaries as J I flashings, valleys, hips, verges and 'spouts, as desired. Copper roofing Z should cost around $22 per square, f f. o. b. Anaconda Montana, for the 9-oz sheets. The shingle Is known as 0 "Anaconda Roofing" and In 99.95 per cent copper. |
