FIBERNOX® V-ROD reinforcement rods

The FIBERNOX® V-ROD reinforcement rods consist of environmentally sustainable fibre-reinforced material. The glass-fibre reinforcement is distinguished by corrosion and alkali resistance, by a high tensile strength at a light weight and by a great adherence in the concrete. FIBERNOX® V-ROD is an effective alternative to rust-proof or electro-plated reinforcement steel.

Key benefits:

  • Corrosion and alkali resistant
  • In comparison to steel reinforced concrete: considerably higher durability of building structures which are exposed to aggressive environmental conditions
  • High tensile strength at a light weight
  • Permeable for magnetic fields and radio-frequencies
  • Dimensionally stable and very good connection with concrete
  • Certified in Canada by CAN CSA S807-10



Made of fibre reinforced material, consisting of glass-fibre lacings with synthetic resin and a special surface finish for best possible connection. Straight or bent bars are available.

Durability of Galvanized Cast-in Channels

Cast-in channels are frequently supplied as a galvanized items, since this is considerably cheaper than stainless steel (by a factor of 3 or 4).

The life of the galvanizing protection depends on the thickness of zinc and the environmental conditions.  The thickness supplied by the major European suppliers of channels is a minimum of 50 ?m (microns), and may be thicker for larger profiles.  However, by considering only this minimum value, it is a simple matter to arrive at the minimum life expectancy for various environments.

Figures for the rate of corrosion of galvanizing in UK are published by The Galvanizers Association in two formats.

The first of these is the Zinc Millennium Map.  This is a map of the UK divided into 10 km squares and for each square; the anticipated rate of corrosion is given in ?m / year.  The map may be accessed via  The figures from the map are only a guide and refer to exterior/exposed conditions.

As an alternative, the Galvanizers Association also publish corrosion rates for different environments, including interior conditions. These are based on BS EN ISO 14713 and are as below.
