Dextra GFRP rebars

The products analysed in this EPD cover 3 different series of GFRP products in 30 diameters in total, including ASTEC & GEOTEC GFRP bars for temporary applications (herein after referred to as Dextra Polyester ) in 12 diameters, ASTEC & GEOTEC GFRP bars for permanent applications in 13 diameters (herein after referred to as Dextra Vinylester), DURABAR GFRP bars for flatwork applications in 5 diameters (herein after referred to as Durabar). 

They are the main products produced in Dextra Guangzhou factory, which are mainly made of glass fibre, resin, polyester thread, silica sand, and sometimes kaolin, and/or polystyrene low-shrinkage addictive. The main differences among the 3 series bars lie in the type and ratio of resin, and the main difference among the products of different diameters under the same series bar is the raw material ratio. Practical production data was collected for 3 representative products of the 3 series respectively, which are the best selling ones of each series. For Dextra Polyester, diameter 41mm was chosen as the representative, for Dextra Vinylester, diameter 16mm was chosen as the representative, and for Durabar, diameter 10mm was the representative. And the specific raw material composition of other diameters are from BOM provided by the producer.

GFRP rebar allow contractors to substitute steel rebar with composite non-corrosive and non-metallic reinforcement. GFRP rebar solutions offer very high tensile performances for a light weight: up to 8 times the performance/weight ratio of steel. GFRP rebars are available in various grades and sizes. Splicing systems are also available. Taylor-made shaped can also manufactured.
