Abstract: Experimental research was done for a new-type wall system of light steel factory building． The research included the behavior of system without outer panel under wind uplift，and the behavior of system with outer panel under wind pressure． The details and process of the experiment were introduced，and through the experiment it was got the load-deformation curve and the load-stress curve，as well as the bearing capacity under both ultimate limit state and serviceability limit state． In contrast with the traditional wall system，the new-type wall system can meet the need of bearing capacity，and its insulation construction process is quite convenient．
