We are a professional manufacturer of WIND TURBINE FOUNDATION ANCHOR BOLT,42CrMoA anchor bolt,34CrNiMo6 10.9 anchor Bolt,,wind foundation anchor bolts.

A193 B7 Anchor bolt

M36 M39 Anchor Bolt

M48 Anchor,M56 anchor bolts

Anchor cage is composed by anchor bolts, 2 anchor plates(templates)-upper template(temporary template, upper anchor bolt), lower template(lower anchor bolt), Steel Nuts, seal nut(nylon nut), Washers(gaskets), adjusting feet assemblies, splice plates(connecting plates), PVC tubes, corrosion protecting grease, fabric,HDPE bolt caps(bolt hat) etc

Anchor bolts are the most important part in this assemblies in WTGS(wind turbine generator system) since this part will bear the pre-stress, pre-tensioning forces, and take responsibility for the stability of the whole turbine or tower. Our manufacturer have the most advanced facility of heat-treatment of steel round bars, which means the pre-stress bearing capacity, tensile strength, yield strength abilities are much higher than the international standard.

We produce 42CrMoA anchor bolts ,stud bolts for wind turbine foundation anchor cages. 42CrMoA is a high level alloy steel grade of  china standard, which equal to
