32x5mm platform checker plate galvanized door mat steel grating
Marco’s welded grating is used universally for walkway and
mezzanine decking applications. It is ideal for most general
industrial and commercial uses. Standard welded grating is
generally considered to included grating with bearing bars spaced
at 1-3/16” or 15/16 and is available in carbon or stainless steel.
Close-mesh grating is similar to standard grating except that
spacing of the bearing bars is closer, ranging from 7/16” to
13/16”. It is suitable for applications requiring narrow spacing
for aesthetic or functional reasons. It is available in carbon or
Welded grating with spacings of 1-9/16” and 1-11/16” meet the
requirements for AAR approved safety walkway products. This grating
is designed specifically for use as railcar brake steps, running
boards, walkways and platforms.
Heavy-Duty uses thicker (1/4”, 5/16”, 3/8”) and deeper bearing
bars. Although the tables show bars as deep as 6”, deeper grating
can be custom fabricated on request. HeavyDuty is used for
airfields, highways, industrial floors, ramps, docks, reinforced
concrete areas and specialty applications.
Because this grating is a system of interlocking, perpendicular
bars, it provides a smooth clean look ideal for architectural
applications such as grilles, dividers and screens. It is used in
the same structural applications as its welded steel and
rectangular aluminum counterparts. Materials include carbon steel,
stainless steel or aluminum. Spacings range from 7/16” to 1-3/16”.
Swage-locked aluminum grating is manufactured with either an “I” or
rectangular bearing bar. These bars are permanently locked to the
cross rods with a swaging process which reshapes the rods. Because
of the flange width, I-bars reduce the open space of the grating
yet-bar swage-locked is lighter is lighter weight and less costly
than a rectangular bar grating with the same bar thickness.
