T4 Welded Fixing Without Nosing Stair Tread For Steel Ladder 40mm
Bearing Bars Pitch
Brief introduction of T4 type flat steel step grating plate with
spacing of 40mm
T4 type steel ladder step grating plate with 40mm flat steel
spacing is the lightest and most economical model. It is an ideal
choice when the span is small. It adopts load flat steel and cross
bar longitude and latitude to design a steel ladder step plate
grating with rectangular grid holes. The side plate size of T4 type
is 65mm * 5mm flat steel, and the bolt hole spacing varies
according to the width of the step plate. See the parameter table
for details.

Performance and application of T4 flat steel step grating plate
with spacing of 40mm
T4 type steel ladder step plate with a spacing of 40mm has the
strongest resistance in the scene of surface impact due to the
small spacing of flat steel and high density of load flat steel.
Moreover, the hot-dip galvanizing treatment process can make it
more corrosion-resistant. It is most widely used in the industrial
field. In addition, its grid hole structure can show advantages in
rainy and snowy weather, free from manual maintenance and cleaning.
Compared with concrete structure, this material has the advantages
of light structure and low price.
