EMCO Weatheredwood™ Steel Siding, Soffit, Fascia & Accessories
General Architectural Specifications
|
EMCO Building Products steel siding and accessory products are produced in a
wide range of colors and are manufactured for residential, new construction and
commercial exteriors or as replacement siding for existing residential and
commercial buildings. With steel siding from EMCO Building Products you get the
strength of steel and the durability of our exclusive EMCO Preserve™ and EMCO
Weatheredwood™ coatings. Because of there toughness and UV, chemical and heat
resistance, it is guaranteed not to rust, crack, blister, chip, peel, flake or
fade. |

Materials
Steel siding and accessories are made from a nominal thickness of .0171
galvanized lock form quality coated steel complying with ASTM 653. Material is
designed for markets requiring roll-form ability and as a result, the steel
substrate is a low carbon alloy designed to take a 2T bend radius. Chemical and
mechanical properties of the steel are detailed in addendum I. The ASTM
standards have been approved for use by government agencies.
Manufacturing
Specifications
A. Siding panels will contain weep hole spaces
approximately every 12 3/4” in the leg of the panel bottom to allow condensation
and water vapor to be released from the wall. Nailing hem of the panel shall be
approximately 3/4” and contain nailing holes uniformly spaced approximately 1/8”
from edge and approximately 1 1/4” on center to provide for expansion and
contraction of siding wall.
B. 16" centervent soffit panels have a minimum
calculated ventilated area (NFOA) of 6.30 square inches per lineal foot.
C.The
coating applied to the substrate shall be a roll-coated paint system designed for use with roll-form machinery. Specific data regarding weatherability and other performance specifications are detailed below
D.EMCO Building Products uses domestic steel sources using a minimum of
70% recycled steel. | Characteristics of Finish
The EMCO Preserve™ and EMCO Weatheredwood™ finish consists of the following
layers permanently adhered to a galvanized steel core. Applied with a unique
10-step thermo bonding coil-coating process, EMCO Weatheredwood™ captures the
texture and woodgraining of real cedar.
Galvanized Steel Core - corrosion resistant galvanized steel provides strength and durability.
Pretreatment Layer - properly prepares the raw steel to receive the next three layers of finish.
Corrosion-Inhibitive Primer Layer - applied to the solid steel core for
corrosion protection.
Water Resistant Backer Layer - applied to the back for added corrosion protection.
Preserve™ and Weatheredwood™- delivers a
consistent color application ensuring an even siding color throughout your
siding job.
Weatheredwood™ - replicates the subtle woodgrain of natural cedar and ensures resistance to the elements. The paint system provides a finish that is resistant to harsh weather and carries a Limited Lifetime 35 Year Warranty against fading and chalking.

Master Color Specifications
Approved color standards only will be used to verify color on coil runs.
Standards to be verified semi-annually against paint vendors standards and will
not deviate more than +/- .5 on any of the “L”, “A” or “B” scales when measured
against master color standards. Preshipment color analysis of coil against
master color standards is required. | | | | |

Characteristics of EMCO Integrity™ (PVC) Finish
(EMCO Integrity™ (PVC) coated surface meets or exceeds
the following test results) |
| |
| Integrity systems are based on high
solids plastisol finished with PVC technology and a specially formulated
corrosion resistant primer. Integrity gives Hot-Dipped Galvanized (HDG) steel,
and zinc alloy substrates the extra corrosion resistance needed for metal
buildings exposed to acid rain in industrial or chemical environments. Smooth,
striated, or textured colors can be produced for metal building wall panels.
Integrity coil coatings are designed to resist abrasion and protect against
common physical abuse caused during transportation and installation. Integrity
may be formed into building panels without micro-cracking on the ribs. |
