The Difference between YXB76-344-688 & YXB76-305-915

The Difference between YXB76-344-688 & YXB76-305-915

In the 50s, floor deck was used in Europe, United States and Japan. With the development of architecture, floor decks are widely used.

In the late 80s, some European and American plate brought to Chinese mainland. Chinese used the United States plate such as 2W, 3W and so on, which later called YXB51-305-915 open pressure plate and YXB76-305-915 open pressure plate. All reference to the US steel plate design and processing standards.

Later, the domestic manufacturers developed their own open plates on the basis of the Europe and the United States plate, which are YXBB51-226-678, YXBB76-344-688 and so on. Then let’s compare these two types of plate.

1.    The Steel Quantity

From the above comparison, we can easily find the steel per square meter YXBB76-305-915 higher than YXBB76-344-688. At the same requirements, the price of YXBB76-305-915 is about 5% lower than that of YXBB76-344-688.

2.    Section Property

From the above comparison, we can find YXB76-305-915 is superior to YXBB76-344-688 in terms of moment of inertia, plus bending moment and negative bending moment.

So the mechanical properties of YXB76-305-915 better than YXB76-344-688.

3.    Standard Spread Width

From the table we can see, YXBB76-305-915 effective width is bigger than YXB76-344-688.

4.    Summary

   From here we see that, YXB76-305-915 board design is better than YXB76-344-688, because it uses a lower amount of steel to provide a greater force performance.
