Corrosion-resistant products

Corrosion is a major problem for metal grating, stair treads, and other products in commercial facilities, usually requiring costly replacement and ongoing maintenance. Fibergrate Composite Structures manufactures a wide range of products specifically designed for environments where chemicals and other corrosive materials attack and destroy metal. Fibergrate’s corrosion-resistant products include molded and pultruded grating, floor plate, pultruded handrail and ladder systems, pedestals, platforms, stairs, and a wide range of structural shapes. Ideal for a wide range of facilities, these products provide longer service life and lower life-cycle costs than metal.

Composite rebar

V-ROD, Pultrall’s composite rebar products offer the following features and benefits when compared to steel rebar: corrosion resistance, lightweight, electromagnetic neutrality (because the bars contain no metal they will not interfere with the operation of sensitive electronic devices).

V-ROD has cost-effective application as a concrete reinforcing bar in the following markets when analyzed on a life-cycle cost basis: reinforced concrete exposed to deicing salts, structures built in or close to sea water, applications subjected to other corrosive agents, applications requiring low electric conductivity or electromagnetic neutrality (such as airport control towers, magnetic resonance imaging in hospitals, and railroad crossing sites), tunneling/boring applications requiring reinforcement of temporary concrete structures, weightsensitive structures, and thermally sensitive applications

Steel reinforced polymer

Hardwire LLC, in partnership with the Structural Group, offers a family of reinforcement products made from ultrahigh strength twisted steel wires. The material provides users the ability to put ultra-high tensile strength steel (11 times stronger than typical steel plate) inside or outside just about any material. Hardwire can be molded easily into thermo-set, thermoplastics, or cementitious resin systems, occupying a reinforcement niche between fibers and steel rebar. Composites made from Hardwire are as much as 70 percent thinner and 25 percent lighter than composites made with glass fibers. The product is priced similar to glass, yet performs like carbon at a fraction of the cost. This creates a new class of reinforcements—micro-rebar—that will work with composite, plastic, and cement-based processes. Further, Hardwire can be used to upgrade steel, wood, or concrete structures in new construction and in retrofit applications.

Cover Story

A brighter outlook

After years of ups and downs, cautious optimism greeted 2012. While economic progress lagged in 2011, this year started off with most in the consulting engineering industry adjusting and rising to the challenges of a volatile economy.
