Custom plain steel and zinc plated u bolts we supply include square, round, and V shaped versions in an endless range of materials - both cut and rolled threads are offered. Most of these u bolts are made using A36 & A307 steel material in plain finish or commercial zinc plated finish with clear sealant. While the zinc plating process makes fast turnarounds more difficult we typically are still able to provide an improved rush lead time option to our customers that are in dire need.
