Series 1 grating self-respect, security, load and deflection tables
Table load weight is affected by the length of more than 1 meter were flat weight. Flat load length by less than 1 meter, the weight due to the increase in the number of wrapping flat increase, which includes the package side and the weight after the hot-dip zinc.
Thick solid line on the left of the span deflection under uniform load in 4KPa less than 4mm, which is the limit of deflection pedestrian shoe comfort.
The span of the table shows the load and deflection and easy set up, the choice of grating length is not limited in size.
For 3mm thick load bearing flat, minus the value from the table is the width of 2mm.
As the manufacture of some of the reasons
