Recently, I came across a question from a netizen asking about how to express the model of pressed steel plates. To address this, we must first clarify what a building board actually means. In mainland standards, press-formed steel plates used for supporting floor concrete are referred to as "press-formed steel plates."
Generally, the model starts with the letters YX, which stand for "profiled," followed by the wave height, wave spacing, and effective width. Occasionally, the initials YXB (for "profiled plate") are used instead.
For those who might not fully grasp this yet, let me break it down with an example. Take the YXB66-240-720 profile as an illustration. This particular type was used in the 2018 Youth Construction Group Yantai Port project, sourced from our company in Shandong Shengbo. Here, YXB66-240-720 indicates a pressed steel plate with a wave height of 66 mm, a wave spacing of 240 mm, and an effective width of 720 mm.
Sometimes, the wave spacing is omitted, resulting in expressions like YXB66-720. Alternatively, it could be written as YX66-240-720 (B), where the "B" signifies it's a closed-end steel plate.
The format described above is quite formal. However, in practice, professionals often use abbreviations for common types. For instance, the 555-type pressed steel plate corresponds to YXB65-185-555, while 2W equals YXB51-305-915, and 3W refers to YXB76-305-915. These abbreviations simplify communication within the industry while maintaining clarity.
Understanding these models helps architects, engineers, and builders select the right materials for construction projects. It’s fascinating how such technical details play a crucial role in ensuring structural integrity and efficiency.
