PREPRINTS - 1959 SWEET'S CATALOGS OS PLIX3IN0, ROOFING AND PUSHDiO
To Members of ths Lead Industries Association
Attached are preprints of our catalogs on "Lead in Modern Plucking" and "Sheet Lead for Roofing and Flashing," vhleh will appear in the 1959 Sweet's Catalogs to be distributed in January, 1959.
The texts are essentially the sane as appeared in the 1958 Sweet's Catalogs, the major change being the addition of a second color and redesign of the covers.
Both of our catalogs will appear in the Sweet's Architectural volume with a circulation of 19,000 architects, and the LlgltCon struction volume with a circulation of 27,000 builders of small hernias and other light construction projects.

i MODERN sheet lead for roofing and flashings
In recent years the cast of lead roofing and (lashing has been lowered to a point where it it comparable--frequently even less--than the cost of other commonly used metals. Hits is because modern metallurgy has produced hard lead--an alloy of lead with between 6 cad 7.5 per cent antimony--w hich is stronger and may be used in thinner, lighter sheets while retaining the well known resistance of lead to corrosion.
for the largest bonding or the smallest home
Thu. the owner of the lirgeit building or the mallcH home now ha within hit reach this fine .licet metal which has long been considered a hall-mark of good construction. Lead's beauty and longevity have featured the great buildings and finest residences of the Old ard New World for centuries. The low er cost and greater strength of the modem alloy now extend its usefulness to modern buildings of all kinds and sizes and in all locations--urban, rural, industrial or by the sea. If properly specified and applied, it should
installation of sheet lead
There are just three important thing* to bear in mind in order to obtain a satisfactory installa tion with hard sheet lead--specify the proper thickness or weight, use sheets of proper size, and install with cleats and loose-locks so that each sheet may expand and contract independently of every other sheet and the surface to which it is applied.
The thickness of sheet lead is usually desig nated by its weight per square foot. l*he weights of hard lead for roofing and flashing are as followt:
% sws* ft fc-Jj iwtitac*
Ibprttfl.o--^ wMk
For most applications in residential work, where areas covered arc generally small and sheets are narrow, 2ji-lb. hard lead should be specified. For most applications on large build ings where areas covered are at.t to be large and sheets wider, 3-lb. hard lead is recommended.
For general flashing purposes, individual sheets should not exceed S ft. in length. How ever, for unusually wide flashings, say 24 in. or more, the length of sheets should be reduced to
2
last as long as any building on which it is in stalled.
the advantages of lead
Does not stain adjacent stone, paint or other materials when water runs over it and then onto the adjoining structure.
Beautiful color, harmonious with all other materials and acquiring a natural patina that improves with age.
Flexibility that permits easier, cheaper in stallation and better fitting to irregular surfaces.
Most durable common metat, noted for corrosion resistance in all kinds of atmos pheres--industrial, urban, rural or sea coast.
About twice as thick as other sheet metals commonly used, adding even further to its durability.
A homogeneous metal all the way through, not just a coating, enabling it always to give the same uniformly good service regardless of surface impairment.
6 ft. For general roofing purposes, sheets 24 in. wide and not more than 4 ft. lnng should be used.
I^cad roofing and flashing sheets should be se cured to the underlying surface by 2'i-Ih. hard lead or 16-oz. copper cleats loose-Inekcd into the edges of the lead sheets. Where the lead sheets arc particularly small, such as flashings inter woven with shingles or slates, the lead may be nailed along one edge only. Adjoining lead sheets mould be loose-locked together so that expansion and contraction arc ctmhncd to individual sheets. Sheets should never be soldered together, solder only being used to place gusset pieces and the like in individual sheets. Where lead is built into ma sonry walls or otherwise rigidly held, continuous loose-lock* should be used to join it to exposed sheet*. Filges of lead slucts turned over copings, cornices, etc., should be loose-locked to continu ous cleats to secure them. l<nosc-locks shouIJ be filled with non hardening compound such as VuK catcx No. 72lM) on flatly pitching surfaces.
In other word*, an understanding of the fact that expansion and lontraction must be localized in small areas and each sheet allowed to move inile|>enderitly of others will lead to successful installations.
