For the standard ‘flange-jointed’ design of the tower, we possess full TUV Nord approval for the manufacture and supply of EN14399-4 products in hot-dip galvanized finish. Sizes range from M16 to M80.

We can also offer various special fastener assemblies to suit customer’s requirements for other forms of tower designs such as lattices.

We offer friction control of the nuts through our in-house lubrication.

In addition, we manufacture and supply ASTM A490M bolts, ASTM A563M 10S nuts and ASTM F436M washer assemblies, which we offer in a variety of corrosion resistant coatings.
