8m Long Span Toothed Steel Grating Customized Press Welding Process
Grating Plate
8m long span toothed steel grating introduction
This product is made of zigzag flat steel with a spacing of 3cm and
fried dough twist steel with a spacing of 10cm, which are welded by
pressure welding machine, and then polished and welded into
semi-finished products to be galvanized. The competitiveness of
this product is that few manufacturers can produce and process this
kind of large-span steel grating plate.
Mechanical properties of 8m long-span steel grating products in
application scenarios
The theoretical weight of g505/30/100 steel grating is 77.9kg per
square meter. The safe external line load and deformation
deflection carried by different spans are as follows:
| 200 | 400 | 600 | 800 | 1000 | 1200 | 1400 | 1600 | 1800 | 2000 | 2200 | 2400 |
| 236 | 118 | 78 | 59 | 47 | 39 | 33 | 29 | 26 | 23 | 21 | 19 |
| 0.11 | 0.44 | 0.99 | 1.77 | 2.77 | 3.99 | 5.39 | 7.11 | 9.14 | 11.18 | 13.7 | 16.26 |
The above are the line load values and deformation deflections
corresponding to different spans of this model. Please process and
customize them according to the actual project. Generally, the
drawings given by the design institute will be designed. If there
is no design drawing, the above reference can be made
Service scenario and performance of 8m long span steel grating
This kind of steel grating is mostly used as the platform for the
construction of steel structure workshop, which is used to carry
heavy objects and resist impact. The workshop generally requires
good ventilation and lighting. The metal plate products of grid
structure can meet this demand. The application industries are
mostly petrochemical industry, municipal engineering, sewage plant,
boiler room, oil refinery, ship wharf, etc. However, ship wharf and
large grain depot unloading area mostly use heavy-duty steel
grating.
The steel grating has good compression resistance. Its flat steel
is installed on the vertical platform, and a large number of flat
steel are densely distributed, forming a very good load-bearing
grid structure; Impact. The horizontal bar will fix and weld the
flat steel. The dense grid has excellent stability. In the
operation of equipment in the plant, the steel grating can offset
the horizontal impact force; The other is its grid hole, which has
good ventilation and daylighting effect. Tooth shape anti-skid is
mostly used in chemical plants and oil refineries.
