The deterioration of reinforced concrete structures in marine environments, resulting from the migration of chloride ions that in turn lead to the corrosion of the steel rebar of the said structures, is a very serious problem of worldwide proportions.
The common solutions to control the steel corrosion like the use of a cathodic protection (sacrificial anode or impressed current), an increase of the concrete cover or the addition of corrosion inhibitors to the concrete mix are generally expensive from the get-go and even in maintenance for some. In some cases, these solutions present an implementation challenge and, to this day, their efficiency is still debatable.
With the product V•ROD of Pultrall...
The V•ROD composite concrete reinforcement rod offered by Pultrall is the ultimate alternative to all these techniques. Totally unaffected by chloride ions, compatible with all other materials (no possibility of creating galvanic corrosion) and making the cover increase as well as the need for additives unnecessary, our rebar is without a doubt your best option.
As if it wasn’t enough, V•ROD exhibits a tensile strength that is 2 to 3 times that of steel, allowing for a reduction in reinforcement ratio in some cases while still ensuring a most efficient crack control.

about V•ROD rebar.
V•ROD rebar does not rust, even in the harshest environments. It does not react to salt, chemical products or the alkalinity present in concrete.
V•ROD rebar does not create a thermal bridge within structures.
She is almost 4 times lighter than steel rebar. It is much easier to handle and, in most cases, one truck load will be sufficient to carry the rebar required on an entire project.
V•ROD rebar offers a level of thermal expansion comparable to concrete due to its 80% silica content.
V•ROD rebar does not contain any metal; it will not cause any interference in contact with strong magnetic fields or when operating sensitive electronic instruments.
V•ROD rebar produced by pultrusion offers a tensile strength that can reach more than five times that of steel.
V•ROD rebar can be delivered at the right time and in the exact quantity needed at the site. Various specifications such as the length of straight bars as well as angles and led lengths of special bent sections are prepared in the plant.
