Steel Specifications
•
Cover-All steel tube
components (trusses,
purlins and
fastening tubes) are
made of ViperSteel
that is clad with
Gatorshield
(exterior finish
provides a minimum
corrosion resistance
of 2000 hours per
salt spray test ASTM
B 117.00; interior
finish is 100% zinc
based organic
coating).
•
Steel tubing has
minimum structural
and mechanical
properties (ASTM
A-500) of 55 KSI
(tension ultimate)
and 50 KSI (yield).
•
All steel flat bar
and other steel
components have
structural and
mechanical
properties (ASTM
A572 GR44) of 65 KSI
(tension ultimate)
and 44 KSI (yield).
•
All cables and
attachment couplers
are made of
galvanized steel.
All bolts have a
minimum Grade 5
specification.
•
All welds are
completed in
accordance with the
CSA Standard W47.1.
•
Cover-All Building
Systems is a CWB
certified Division 2
manufacturer of
Fusion Welded Steel
Structures, covering
similar criteria as
set out in AWS D1.1.
Quality Assurance
Testing
Cover-All’s use of
ViperSteel ensures
that customers
receive the best
steel framework
assembly available.
ViperSteel is clad
with triple coated
Gatorshield
corrosion barrier.
Independent
salt-spray tests,
conducted by
Scientific Control
Laboratories Inc. of
Chicago, show
Gatorshield
outperformed
competitive products
in rust resistance
and corrosion three
to one. All welds
are sandblasted,
then finished with a
state-of-the-art
molten zinc
corrosion protection
process. This
assures that the
corrosion resistance
of the weld zone is
fully restored to
the service life of
the tubes’ original,
galvanized finish.
Steel vs. Aluminum
Steel is more widely
used than aluminum
in construction for
load bearing
applications for
many reasons
including cost,
strength and
resistance to
denting and warping.
In comparable sizes,
steel is 50%
stronger in load
carrying
applications and
deflects one-third
the amount of
aluminum. The
fatigue life of
aluminum is 80% that
of steel. This means
that aluminum, over
time and under load
conditions, will
deform and creep
faster than steel.
Steel is recycled
more than paper,
plastic and aluminum
combined, making it
the environmentally
friendly building
material choice.
