HIGHLY RECOMMENDED for coastal environments with high levels of salt containing humid air. If the product is being installed within 2 miles of a body of salt water, the Harsh Environment Protection Package is essential to protect the beauty and longevity of the DesignRail® railing system. In addition to increased rates of deterioration, high exposure to salt in the air can cause a reaction between dissimilar metals (i.e., stainless steel and aluminum). This reaction is called electrolysis, and can create unsightly oxidation stains on the railing. DesignRail ® Custom Harsh Environment Protection DO YOU NEED THE HARSH ENVIRONMENT PACKAGE?
Two examples of aluminum guardrail systems installed in coastal environ - ments without protective isolation. Corrosion damage created by electrolysis has occurred, due to the reaction between the stainless steel cables, the aluminum posts, and exposure to salt in the air.
RECOMMENDED for areas prone to contamination caused by frequent use of deicing salts during winter seasons, and areas with potential for acid rain caused by corrosive pollutants. Corrosion in these areas is caused by deicing salts, marine salts, and other corrosive pollutants that can lead to acid rain.
The map at right illustrates the areas in the U.S. that have the highest concentration of corrosion exposure. .
