How to determine the application direction of steel grid plate
The length of a steel grid refers to the direction that carries the flat steel, and the width of the steel grid refers to the size measured in the direction along the cross bar (usually the cross bar with a twist Jiao Fanggang)
The width of the groove generally refers to the length of the steel grid (including the required width of the groove), and the width of the steel plate along the longitudinal direction of the groove
This order must be strict and clear. The steel grid plate in the length direction (flat length direction) on at both ends of a supporting beam, i.e. use or the use of slot, and ends in the width direction can not need support. Because the bearing capacity of steel plate mainly from the flat direction. For example drain cover
