Stainless Steel 316 Spacer Round Type - Hollow / CU-U
This product is a round hollow spacer made of stainless steel SUS316, which boasts extremely high corrosion resistance. It features a simple cylindrical structure with a through hole, supporting the spacing and height adjustment of components under harsh conditions. The material SUS316 is a grade that enhances corrosion resistance by adding molybdenum to SUS304. It is resistant to rust even in severe climatic environments and corrosive atmospheres, maintaining its performance and appearance over long periods. It is an ideal choice for situations where maintenance frequency of equipment needs to be minimized, for long-term outdoor use, or for structural integrity in environments prone to chemical influences. Additionally, the non-plated material characteristics minimize the risk of peeling from parts and foreign matter contamination. With a design that offers high rigidity, it is resistant to deformation even under heavy loads, allowing for the construction of a stable structure. It strongly supports engineering that demands uncompromising quality even under harsh conditions.
