The density and the strength of the decking?

The #density of our #wpcdecking is 1.3%-1.4%(1300-1400kgs/cbm). 

The #strength of the #hollow one is about 320kgs.

(That's to say, based on the space between the #keels of 35cm, the decking surface can bear the weight of 320kgs.) 

And the strength of the #solid one is 400kgs-500kgs.
