Feature of OA-600 Steel Raised Floor: 1. 60 perimeter welds as compared to 40 in earlier design, which greatly improves the panel edge loading capacity. 2. Every Huili panel is put into a flatting press and checked for flatness after welding. Huili is the only company to go this extra process in order to guarantee a super flat panel. 3. 32 reverse structural embossments. One at the center intersection of each structural cup. This eliminates the flat areas which are weak spots in early designs. Which helps in the panel ultimate loading capacity. 4. Huili panels come with 90 degree deep stretch steel beam corners, filled with high strength cement. And load applied on the panel will be transferred to the panel corners before travelling through the pedestals to the sub-floor.
