Steel Grating is also called
steel grate, steel grate mesh or metal grid mesh. It is made
by stainless or mild steel of certain sizes through the processing of
grooving, lock-pressure, welding, finishing and other treatment. Galvanized
steel grating is the mostly used one due to its economic cost and good
property.
Material: Mild Steel (Low carbon steel) / Stainless
steel
Steel grating
types:
There are three
kinds of steel gratings distinguished by different bearing bar types.
The respective of
features are as follows:
Plain: the most
widely used gratings, available for flooring sidewalk, all kinds of ditch
cover, Stair Tread, etc.
Serrated: best
non-skid property & safety compared with plain grating.
I-shape: lighter,
Not substantially weaken the case of load capacity more economical and
practical comparing with plain grating.

Application of Ceramic Tools on High Speed ​​Finishing of Quenched Surfaces (Part II)
3. Structural design of the tool The new ceramic blade, like most carbide inserts, is mostly a flat blade without holes and back angles. The ceramic blade has extremely poor solderability, and the upper-press type mechanical clamping method makes the clamping quick and simple. Figure 6 shows a simplified view of the cutterhead and the toolholder used in our test. For the sake of simplicity, we chose a universal end mill cutter disc. The size of the cutter disc directly affects the high-speed finish milling results.
