Now, the following task is to create the design for the testing gate framework. After our research on structural steel, we've chosen to use box steel because it's widely available and well-liked for structural projects, following the standards in Thailand and Japan.These standards feature three typical steel grades: SS300, SS400, and SS490, each with their own specific properties and compositions. But it's important to mention that SS400 is the most widely used grade and can be easily found in stores. To help with the design process, we'll be using the SolidWorks software.
