Plain Bar Stainless Steel Grating Walkway Twisted Bar Anti
Corrosive
1. Description
Steel Bar Gratings are manufactured with the world’s first-class
computer-controlled pressure resistance welding machine by
electro-forging the twisted square-steel into flat steel.Steel Bar
Gratings are classified into three styles,namely plain
style,serrated and I style as per the upper edges of bearing bars
.More than 200 varieties are available based on specifications and
spacing of bearing bars ,and that of cross roda.Different
protective treatment can be made on the surface as environment
varies.
2. Application
steel bar grating is mainly used in chemical industry, food
processing, hydro processing and other industries as listed :
- Power plant
- Chemical plant
- Oil Refinery
- Steel plant
- Machinery plant
- Paper-making factory
- Cement plant
- Civil engineering
- Wastewater treatment
- Pharmacy industry
- Food processing

4. Feature Advantage
1.Attractive appearance:Simple outline.silver colour,and modern.
2.Optimum water draining:Water leakage area reaches 83.3%,which is
more than two times larger than that of cast iron.
3.Hot-dip galvanizing:Good antirust performance,maintenance free
and replacement free.
4.Design of preventing theft:The cover is connected with the frame
by gemel,which ensures protection against theft,safety,and
convenient opening.
5.Saving investment:With large span,the cost is lower than that of
cast iron when under heavy load.And the replacement expenses in
case of theft and crushing will be saved.
6.High strength:With strength:With strength and toughness far
higher than those of cast iron,it can be used in the environment
with large span and heavy load,such as the wharf and the airport.
7.Many specifications available: The requirement of different
environments,loads,spans,sizes and shapes can be satisfied.
