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, Highland will
manufacture Ships Ladders for job
sites with limited space and can
custom fabricate ladders, platforms
and walkways to suit your
site-specific needs.
