Omega II is the "original" North American manufacturer who in 1992 introduced to the market a fresh new style of fencing systems. Since then, we can count thousands of projects and millions of linear feet enhancing the image of landscaping projects throughout North America and beyond.
At Omega II we understand the need for versatility and change in the market place. We dedicate our efforts to offer outstanding fence systems at a competitive price for industrial, commercial, residential and custom designs.
Our goal is to successfully integrate beauty, security and strength to produce the ideal fence for all projects, deterring even the most motivated trespasser and allowing your concept to shine through.
