Frequently Asked Questions
What are the construction details?
All PermaDock materials are corrosion resistant steel or non-ferrous polymers.
No galvanized, aluminum, wood or concrete is used.
PermaDock pultrusions have complete ultraviolet veiling.
Fabrication standards meet or exceed the certified material manufacturer’s criteria.
In addition to adhesives, all PermaDock structural joints are doubled up with
316 CRES gussets and bolts.
All pultruded fiberglass shapes are manufactured under ISO-9001:2000 certification.
PermaDock’s adhesives meet or exceed ASTMD 1002-64.
How long will a PermaDock last?
Scores of off-shore drilling rigs have had exterior manways of the materials
used in PermaDock in place for decades; some for as long as 45 years. Even
in that environment, there has been no evidence of deterioration- so it’s a long time!
What dockside reagents will react with PermaDock?
A few of the more violent organic solvents, e.g., acetone, benzene, ketone, toluene
and xylene, will penetrate the protective veil and react with the resin if a PermaDock
is immersed in them for an extended period. So don’t do that. Otherwise, spills and
splashes will evaporate long before damaging a PermaDock.
Will PermaDock survive storm and heavy vessel impacts?
Like a fiberglass fishing pole, a PermaDock, as a fiberglass structure, shares the
fishing pole’s ability to absorb massive sudden loads with full recovery. Please see
the Engineer’s Memo’s page for more on this subject.
What about PermaDock’s adhesives?
The glass window walls on high-rise buildings are held on with some of the same
adhesives used on a PermaDock. The Boeing 777 and Dreamliner are largely
plastic composite structures held together with space age adhesives as used on
PermaDock. The adhesive joints have been exhaustively tested, including by 3M.
