High Ribbed AT Bar

Key Features

• Manufactured from a special hot rolled deformed bar designed by DSI Underground.
• This bolt features a rib pattern which actively assists with mixing the chemical anchors during installation.
• The AT bolt typically provides marginally higher fracture toughness results over standard AX bar when measured by Charpy Impact Test.
• The deformed rib pattern improves load transfer properties.
• The rolled thread strength nominally equals the column strength of the bar.
• The 24mm chemical anchor bolt is designed to be used with the chemical anchors, but can be effectively used with cementitious grouts.
• Corrosion protection may be provided by hot dip galvanizing or alternative coatings
