Marine Projects

Portland Bolt manufactures a variety of different fasteners for marine construction projects. Due to the corrosive environment these bolts are subjected to, marine fasteners are typically hot-dip galvanized or stainless steel. Portland Bolt has the ability to manufacture and galvanize these special bolts, rods, and fabricated plates completely in-house.

Fender Replacement - Port of Houston, Texas

The Turning Basin Terminal fender replacement at Wharf 16 was part of a $25 million Port of Houston improvement project. Each year, over 2,800 ships and barges use this convenient terminal to move products all over the world. A Houston civil contractor was awarded the job to remove and replace the deteriorating fenders at this wharf.

Portland Bolt provided galvanized timber bolts and shear plates for this customer. The plans required a custom slot to be machined into the round head, to allow easy installation in the field. Our large inventory of shear plates and ability to manufacture galvanized timber bolts in-house, allowed us to deliver this product quickly to the Gulf Coast region.

Shilshole Bay Marina - Port of Seattle

After almost 50 years, the Port of Seattle needed to upgrade the aging Shilshole Bay Marina. Starting in August of 2005 Portland Bolt began providing 3/4" and 1" diameter hot-dip galvanized through-rods, used to secure the large concrete floats.  With over the 1,400 slips to replace, this extensive project will continue through 2008.

Our in-house hot-dip galvanizing and economical threading capabilities allow quick delivery of the nonstandard bolts needed to help keep the Shilshole Bay project on track.

Great Salt Lake Marina - Salt Lake City, Utah

Since March of 2002, Portland Bolt has supplied over 40,000 pounds of galvanized timber bolts and other marine fasteners for the construction of docking systems at the Great Salt Lake Marina.

The Great Salt Lake is three to nine times saltier than the ocean and currently is about 18% salinity. Hurricane force winds with gusts over 100 mph occur regularly. The marina has over 300 slips with only three or four power boats, the highest ratio of sailboats to power boats of any public marina in the United States.
