Just now, I came across a netizen on Baidu Shangqiao asking about the meaning of "floor bearing plate 688." As someone well-versed in the field of pressed steel plates, let me explain what this term means.
The 688 steel structure pressed steel plate is short for the YX76-344-688 steel structure pressed steel plate. This model, YXB76-344-688, was one of the first batches of pressed steel plates developed in China. It’s an open-style pressed steel plate designed with a high peak structure, which aligns better with the mechanical properties required for large-span projects. This design reduces the need for temporary supports during construction, significantly cutting down on costs.
Let's look at the basic technical specifications of the 688-type steel structure pressed steel plate. Its standard expanded width is 1000mm, with a wave height of 76mm and a wave spacing (effective coverage width) of 344mm, achieving a board utilization rate of 68.8%. These plates are manufactured using cold-pressed hot-dip galvanized steel sheets, but they can also be produced from color-coated steel coils. Common thicknesses include 0.75mm, 1.0mm, 1.2mm, and 1.5mm. The production and acceptance processes strictly adhere to the requirements of the national pressed steel plate standard, GB/T12755-2008.
Those familiar with the pressed steel plate industry know that YXB76-344-688 was developed domestically based on references to the European and American YXB76-305-915 (also known as the 3W pressed steel plate) model.
However, when it comes to either product cost or effective coverage width, YXB76-305-915 outperforms YXB76-344-688. Hence, we usually suggest customers opt for YXB76-305-915 over YXB76-344-688 whenever the project permits. For instance, in November 2019, the Dongying Domestic Waste Incineration Power Plant project of Sichuan Huashen Group utilized Shandong Shengbo’s YXB76-305-915 open pressed steel plate.
In conclusion, while YXB76-344-688 has its advantages, YXB76-305-915 tends to be a more cost-effective and efficient choice for most projects.
