Zinc has a long and well-developed history as a building material. For more than 200 years it has been used to clad and roof buildings in
Europe. During the last several decades, it has gained popularity on
North American buildings for its sustainability, resiliency,
recyclability and versatility. The benefits of architectural zinc
products support criteria for several state and federal green building
initiatives, and programs including BREEAM® certification, the Cradle to
Cradle Products Innovation Institute, the Green Globes system and the
U.S. Green Building Council’s LEED® rating system.To get more news about

Architectural zinc façade and wall cladding systems are consistently chosen as an environmentally responsible, durable alternative to other
exterior siding and panel materials. Zinc is efficient to produce and
has almost no waste. In contrast to some synthetic materials used in
façade applications, architectural grade zinc alloys contain none of the
impurities that can leach heavy metals into the soil or release them
into the atmosphere. Zinc is not combustible or harmed by UV rays; and
it does not rot, rust or need repainting. Fabricated into wall cladding
and façade systems, zinc requires no hazardous cleaning chemicals and
little effort to maintain once it is installed on the facade.
Longevity is another of the key values that zinc offers. Used in façade and wall cladding systems, architectural zinc is capable of
maintaining its self-healing, low-maintenance, corrosion-resistant
performance with a potential lifespan of 100 years or more. At the end
of the zinc product’s useful life on a building, the material remains
100% recyclable; without the loss of existing properties.
A proven and dependable material, architectural rolled zinc products complement both contemporary and traditional architectural styles, and
fosters a connection to the natural environment. As buildings weather
and age, their zinc façade products develop a recognizable patina unique
to the projects’ sites. The patination process forms through exposure
to the local climate to protect the zinc from corrosion and to
continuously evolve as a natural metal artwork.
Zinc façade and wall cladding systems offer protections from weathering to the load-bearing,
waterproof and insulating layers of the structure. Used in a rain
screen assembly, zinc further protects the substrate and vapor barrier
from weathering and allows the façade’s heat gain to dissipate through
air convection. This strategy can be employed to help increase a
building’s energy efficiency and reduce the heat island effect.
For façade systems, wall cladding products and other building applications, architectural zinc is manufactured in continuous 39.4- or
19.7-inch-wide strips. These are shipped as either flat sheets or rolled
coils in 24, 22, 20, 18, 16 and 14-gauge thicknesses. Minimizing waste,
these environmentally friendly and economical rolls generally yield two
panels at 15.75- to 16.75-inch widths, depending on the profile. Tiles
and panels can be fabricated as roll-formed or brake-formed engineered
wall cladding systems. Any scrap that is generated is 100% recyclable.
