47*117 grooved tube size, various grooved tube specifications, non-standard groove tubeHere are some common groove tube specifications; however, the specific production and market supply may vary by manufacturer and demand: 1. **Small Size Series**: - **30×30**: Square cross-section with side lengths of 30mm, groove size and depth may vary according to specific requirements, commonly used for small structural components or decorative purposes, with standard thicknesses of around 0.8 - 1.0mm. - **32×32**: Square cross-section with side lengths of 32mm, also a common small size groove tube, suitable for occasions with low space and load requirements, with thicknesses generally around 0.8 - 1.0mm. 2. **Medium Size Series**: - **40×40**: Square cross-section with side lengths of 40mm, often used in construction and mechanical manufacturing fields, such as supporting components for some framework structures or decorative lines, with thicknesses typically between 1.0 - 2.0mm. - **40×60**: Rectangular cross-section, with lengths of 60mm and widths of 40mm, offering certain load-bearing capacity and stability, suitable for structures with specific size and strength requirements. - **50×50**: Square cross-section with side lengths of 50mm, with higher strength and stability, used for supporting or connecting components in large structures, with thicknesses around 1.5 - 3.0mm. 3. **Large Size Series**: - **60×60**: Square cross-section with side lengths of 60mm, commonly used in large-scale construction structures, bridge engineering, and other situations with high requirements for tube strength and dimensions, with thicknesses generally between 2.0 - 4.0mm. - **80×80**: Side lengths reaching 80mm, a larger size groove tube, possibly used in special large-scale projects or heavy-duty equipment, with thicknesses of 3.0mm and above.

Regarding the "47×117 grooved tube" you mentioned, it may fall under the category of non-standard grooved tubes. Non-standard grooved tubes are customized based on specific engineering requirements or customer demands, and their dimensions, shapes, and materials may differ from those of standard grooved tubes. These non-standard grooved tubes can be found in special construction projects, machinery manufacturing, or other customized applications, but the exact dimensions and performance parameters must be determined according to the actual production and design requirements.
