Kriska and Snina are made of aluminum. They are lightweight and resistant. Our products are manufactured in our facilities from start to finish: from manufacturing the chain links with raw aluminum to the structures installed in each project. Our chain links are made of 99.99% aluminum and are subject to a special anodized treatment that makes them harder, and grants their color a higher resistance to climate factors, friction, and rust. They are waterproof, odorless, and good light reflectors. They are not magnetic or toxic.
