密型钢格栅板是指承载扁钢间距小于25mm的压焊钢格栅板。
Close-section steel grille is a kind of pressure-welded steel grille with spacing less than 25 mm for carrying flat steel.
密型钢格栅板又叫重载荷钢格栅板，是指采用更厚、更宽的承载扁钢制作而成，专门用在有需要承载重物的场合，适用于机场、高速公路、工业平台、港口码头以及其它特殊需求的场合。对于行车载荷的重荷载钢格栅板，为提供更好摩擦力，我们建议选用齿型钢格栅板，压焊钢格栅板和压锁钢格栅板均能采用齿型扁钢。
Dense steel grilles, also known as heavy-duty steel grilles, are made of thicker and wider flat steel for carrying heavy objects. They are specially used in occasions where heavy objects need to be carried. They are suitable for airports, highways, industrial platforms, port terminals and other special needs. In order to provide better friction for heavy load steel grids under traffic loads, we suggest that teeth-shaped steel grids should be selected, and that teeth-shaped flat steel can be used for both pressure welded steel grids and pressure lock steel grids.
