Material Of Anchor Bolt

Anchor bolts have different forms of wool, thick rod and thin rod. Wool is the raw material steel without modification. It is directly processed from round steel or wire; thick rods or A-type, thin rods or B-type are all converted from steel to the corresponding required diameter and processed.

The anchor bolts are generally made of Q235 steel, which is round. Rebar (Q345) has high strength, and it is not easy to make a nut screw. For light round anchor bolts, the burial depth is generally 25 times its diameter, and then make a 90-degree hook about 120mm long. If the bolt diameter is large (such as 45mm) and the burial depth is too deep, you can weld the square plate at the end of the bolt, that is, make a big head. The burial depth and the hook are to ensure the friction between the bolt and the foundation, not to Pull out the bolts and damage them.

Fixed anchor bolts, also called short anchor bolts, are poured together with the foundation to fix equipment without strong vibration and impact. Movable anchor bolt, also known as long anchor bolt, is a detachable anchor bolt used to fix heavy mechanical equipment with strong vibration and impact. Expansion anchor anchor bolts are often used to fix simple equipment or auxiliary equipment at rest.
