New brand identity | Orga

The way ahead with a fresh look

We are proud of our heritage of 45 years as trusted partner in solutions for marking assets and landing areas to ensure safe operations. Now it was time to reflect our ongoing strive for innovation and vibrant relationships in a brand new identity. We want our brand to reflect our values and capabilities in protecting people, assets and the environment. You will notice new and refreshed identity elements like our logo and brighter colours. The yellow reflects a linkage to signaling and safety marking. We kept our lower case Orga letters referring to our heritage and DNA.

New website

The new brand identity will be introduced over the coming period. An important step will be a new website which will be launched soon. The new site will be more inspiring and user-friendly in demonstrating Orga’s solutions and proven track record. Stay tuned!
