Stairways
Highland Tank fabricates standard
and custom stairs to facilitate access
to tank fill ports and manways.
OSHA standard design stairways
provide access to the top of the
tank from a platform attached to one
end of the tank and include non-
skid fiberglass grating on the stair
treads and platforms. Handrails and
provisions for anchoring stairway to
a support pad are also included. In
addition, we can manufacture Ships
Ladders for job sites with limited
space and can custom fabricate
ladders, platforms and walkways to
suit your site-specific needs.
