mateenbolt™ GFRP rock-bolts & soil anchors have precision machined threads and use composite plastic nuts and washer plates to increase head strength and maximize holding power of each bolt.

mateenbolt™ is produced in the following two durability grades:

• Temporary - Low-cost bolts that can be cut for temporary ground support and are generally used in metro and other tunnelling projects where a TBM drills-through the reinforcement; and
• Permanent - Used for long-term bolting or soil-nailing in corrosive (alkali or acidic) environments, replacing galvanized, epoxy coated, stainless or double corrosion protected bolts.

Advantages
• High tensile strength – over twice that of steel
• High shear strength
• Cuttable bolts for temporary ground support
• NATM/SEM/Lunardi tunnelling method ground support
• Bolting or Soil-nailing in corrosive (alkali or acidic) environments as a successor for galvanised, epoxy, stainless or double corrosion protected bolts
• Hollow bolt option available
• Light Weight - 1/3 of steel products

Applications
• Temporary/permanent
• Face stabilisation
• Slope stabilisation
• Ground support
• Systematic rock bolting
• Concrete form tie

Specifications
Both grades of bolts are available in 22mm, 25mm and 32mm configurations in lengths of 6m and 12m that are fully threaded.
Custom rockbolts to meet specific needs of the client can be discussed - we have developed over 20 different rockbolt types to suit the market needs.
