(800) 962-6973, or equal.
B. Substituted manufacturer to be equal in all product specifications.
2.02 Materials
A. All Aluminum Rain Removal Systems shall be made of 3105-H26 aluminum sheet (minimum tensile
strength 26,000 psi, minimum yield strength 22,000 psi) or equivalent.
B. The finish is Alcoa's Alumalure 2000®, applied in two separate coating operations and is baked on
for added protection and longer life. The finish shall be a two-coat acrylic finish applied in a twophase
operation which includes a corrosion-inhibiting primer and a baked-on, high-performance
acrylic topcoat. The finish is highly weather-resistant and provides the gutter with high performance
and appearance qualities. The Alumalure 2000 finish system is warranted against chipping, flaking
and peeling, inside and out, with a lifetime limited warranty. Prior to finishing, the metal shall
receive a special cleaning process to assure maximum finish adhesion. The inside of all gutters
and downspouts shall be coated with a special gold-colored corrosion-inhibiting finish.
2.03 Hanger Systems Description
A. The Rain Removal Systems shall be designed to be free-floating, enabling the gutter to expand and
contract with temperature changes, while minimizing stress points which cause buckling and leaks.
B. System gutters, when properly installed, will support a minimum of 50 pounds (22.7 kg) per lineal
foot. Six different types of free-floating hanger systems are available in the 5" (127) series, and four
hanger systems are available in the 6" (152.4) series. These hanger systems permit the gutter to
be used in both new construction and all types of remodeling work. Gutter hangers to be .051" -
.082" (1.3 - 2.1) gauge, depending on the style specified.
C. All hanger systems provide a concealed attachment at the front of the gutter, eliminating any
exposed protrusions that would detract from the appearance of the gutter. Spikes and ferrules
(which restrict the movement of the gutter) and brackets attached to the outside periphery of the
gutter shall not be used.
