Lead Coated Copper Overview
When a durable, naturally weathering architectural metal roof is called for, Lead Coated Copper (LCC) is appropriate for use in most applications. With all the characteristics of copper, coated with molten lead on both sides, it requires no maintenance, as it slowly begins to develop a slightly darker grey (or in some applications red) patina. LCC may be used not only for roof and wall cladding systems, but also to form most architectural accents. LCC is relatively corrosion resistant to harsh coastal climates. However, in some marine environments proper care should be taken to avoid residual staining due to runoff.
The color or appearance of LCC can vary due to the composition of patina. Depending upon degree of exposure and local (micro) environmental conditions, these can include a host of oxides, sulfides, sulfates, carbonates, hydroxides, chlorides, etc. Although LCC is rather inconsistent and muddled during or shortly after it is installed, it will shortly form a living, soft, uniform gray finish.
Conventional installation and fabrication techniques, similar to those used for other architectural metals, apply to LCC. Its workability is comparable to zinc. Standard metal forming tools, processing and machinery are employed. LCC can be soldered, and accepts adhesives and sealants well. LCC is available in coil and sheet widths up to 36” wide. Typical thicknesses from .020” to .032”-
Green Building Product
Sustainable materials are key elements of green buildings. Some benefits of sustainable materials include durability, long life, recyclability, and energy and thermal efficiency. Copper and Copper alloys like LCC rank highly in all of these categories.
A Cost Effective Building Material
LCC offers numerous advantages over other finishes. Like all architectural copper, LCC is easy to form, simple to install and durable in most environmental conditions. LCC is competitively priced with other architectural metals. LCC’s corrosion immunity lowers its installed unit cost. Well-researched designs that exploit its unique attributes and long-term savings from durability and low maintenance make LCC a competitive architectural building material on a lifecycle basis. 25 Year Coastal Warranty.
