钢格板分类的型号、纵条的侧边状态和表面保护状况等，可用代号表示：

（The clarified type of the grating, the side shape of the bearing-bar and the finish can be shown with mark.）
        注：Note

⑴ 横条的间距有A、B两种，A表示中心距为100mm，B表示中心距为50mm.
⑴ A,B are the two types of cross bar pitch A=100mm（center to certer）B=50mm（center to certer）

⑵ 纵条的间距有三种：
1表示系列1，间距为30mm（中心距）
2表示系列2，间距为40mm（中心距）
3表示系列3，间距为60mm（中心距）

⑵ There are three types of bearing-bar pitch

 Bearing bar pitch: Series1（1）= 30mm（center to certer）
Series2（2）= 40mm（center to certer）
Series3（3）= 60mm（center to certer）

⑶ 纵条的侧边状态有P、S两种：

 P表示平面形（在标记中可省略）；S表示齿形。
There are two types (P.S) for the sides Shape of the bearing bar
P=Plain   S=Serrated

⑷ 表面状态有G、B、PT、U四种

There are four types-G,B,PT,U for the finish
G表示热浸镀锌；G=hot-gavanized
B表示浸渍 沥青；B=bitumen paint-dipped
PT表示涂漆；PT=Painted
U表示不处理（在标记中可省略）。U=untreated (it can be omitted in the mark)         

 

订货型号标记示例（Mark of picking up goods）

用32×5扁钢，纵条间距为30 mm，横条间距为100mm的压焊钢格板，后经热浸镀锌处理。其标记为WA325/1-G。用侧边为齿形40×5扁钢，纵条间距为40 mm，横条间距为50mm，表面涂漆的钢格板，其标记为WB405/25-PT。

As for the flat-steel of 32×5: Bearing Bar Pitch:30; Cross Bar Pitch:100. This welded-steel grating galvanized is marked with WA325/1-G

As for the serrated-sides flat-steel of 40×5: Bearing Bar Pitch:40; Cross Bar Pitch:50. This kind of grating finished with paint is marked with WB405/25-PT。

注：表中宽度按扁钢厚度5mm计算的。如果用3mm厚的扁钢，则应减去2mm。

The widths in the table are calculated according to the bearing bar thickness of 5mm. When using bearing bar thickness of 3mm, the widths should be reduced by 2mm。


钢格板的尺寸（The Dimension of the Steel Grating）

原板的尺寸一般为6m，可按用户的需要适当延长或减短。其宽度见右图。

The Pannel size is normally 6m, it can be lengthened or shortened appropriately as requested. As for the width. Please see the right figure.

钢格板固定的方法有两种。对于安装后不需拆卸的可采用焊接方法，将钢格板的四角同支承构件焊接起来，其角缝焊高3MM，焊缝长不小于20MM，见图① 。对于需经常开启的钢格板，则可采用安装卡，每块钢格板至少用4个安装卡，在钢格板的四角与支承件卡紧而固定。安装卡的用法见图 ② 和图 ③ 。我公司可提供上图的2种安装卡，用户在订购钢格板时可选用，并请注明用何型号。

There are two fastening methods for the steel-grating. If there’s no need of loading after installation then it can use welding method. Weld the four corners of the steel-grating and the supporting member. The welding slot height is 3mm.
The welding slot length is less than 20mm. See Figure ①.
To remove the steel-grating frequently then it is necessary to use the saddle-clip.
Every piece of steel-grating needs at least four saddle clips. Fasten and fix the four corners to the supporting parts. As for the method of application, please see Figure② ③ . Our company can provide the above two saddle clips. The user can select them when ordering steel-gratin, and please mark which kind of type you want to use.
