Interna-Rail® Overview and Features

For applications which require a sleek architectural design and finish.

  • Appearance – Design of Interna-Rail® combines the clean look of welded rail with all the benefits of a mechanical system.
  • Strength – Interna-Rail® can be designed to meet any building code. Please refer to the structural test data.
  • Corrosion Resistance – All Interna-Rail® aluminum fittings are supplied with a 215-R1 anodized finish which provides additional resistance to corrosion and staining. The hardware supplied with the product is stainless steel. Mill finish fittings are also available.
  • Durability – The double tang set screw activated design provides a virtually maintenance free system which is inherently longer lasting than those which utilize adhesives and pop rivet.
