钢格栅规格表

一、纲格栅板各XZ种规格二、型号分类及标记说明标记：

钢格栅板分类的型号、纵条的侧边状态和表面保护状况等，可用代号表示。

注：1、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。

2、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)。

3、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。

4、表面状态有G、B、PT、U四种：G表示热浸镀锌；B表示浸渍沥青；PT表示涂漆；U表示不处理(在标记中可省略)。三、安全载荷、挠度、跨距表钢格板第1页
