GTI COMPOSITE STACK CHAIRS (SERIES 291)

          
 
GTI® provides the strongest Composite Stack Chairs available in the market.  They are made from composite material and exceed the strength of comparable wire supports by up to ten times.  The product size is identified on the top of the product.  GTI® composite material offers continuous corrosion protection, both on the job-site and in concrete providing a great alternative to epoxy, stainless, and galvanized bar supports.
 
The GTI® line of Composite Stack Chairs contains rounded balls on the bottom of the feet so as not to damage formwork and remain invisible when concrete is exposed.  GTI Composite Stack Chairs are grey in color (custom colors are available) to blend in with concrete and show virtually no change in strength in temperatures ranging from 0ºF to 300ºF.
