Delta SBD is pleased to announce that through an exclusive alliance with leading international materials company Saint-Gobain ADFORS, it will be providing a high quality, proven longwall recovery mesh system to the Australian market. This product, which will be known in Australia as DeltaGRID, has been extensively proven in the American market by leading US industrial engineering company Tensar. Tensar has provided the product as the American agent for the Saint-Gobain ADFORS for more than 20 years. Tensar boasts a majority market share in the highly competitive American longwall market.

Delta SBD is the market leader in longwall moves, participating in more than a third of all longwall projects in Australia and recently having completed its 100th longwall move project, a major milestone for the company. Using its extensive expertise in longwall management, Delta SBD will provide clients with a fully customised DeltaGRID recovery mesh solution including product design and support, delivery and installation. DeltaGRID is a knitted polyester mesh used in underground coal mines as roof protection to provide a safe working environment to allow for the recovery of longwall equipment.

The product is manufactured in India by Saint-Gobain ADFORS to the highest of standards. The product is then tested in accordance with ASTM D6637. The ASTM D6637 testing methodology covers the determination of the tensile strength properties of geogrids by subjecting strips of varying width to tensile loading.
The material complies with the requirements of MDG3608, 6.3.1 for Fire Resistance and MDG3608, 6.3.2 for Electrical Resistance and therefore will be supplied certified as Fire- Resistant Anti-Static (F.R.A.S.).
