ASTM Specifications

Double Twisted Hexagonal Mesh Gabion Baskets and Mattresses have been used world wide for retaining wall, slope stabilization, channel lining, rockfall protection and many other applications for over 100 years. Due to the low cost long term solution double twisted mesh gabions provide for these applications their usage has become common place with many Government Agencies, and Private Land Developments etc�� here in the United States. As gabion usage grew domestically the requirement for an industry standard of product quality became vital to ensure material consistency. The AMERICAN SOCIETY OF MATERIALS AND TESTING has long been recognized as requiring high quality standards and assisting industries in establishing an industry standard for specific materials and products. The AMERICAN SOCIETY OF MATERIALS AND TESTING (ASTM) publishes a specification book which documents each specification in its entire format. Each individual product specification within the ASTM book is designated a specification number for reference. The ASTM specification number for Double Twisted Hexagonal Mesh Gabions is ASTM A975-97.
The full version of ASTM A975-97 specification is not shown in its entirety. The performance requirements of the finished product and the material data information are represented.
