SUS316 Stainless Steel Pipe for Lifting Columns
Leave a message
In modern applications such as electric standing desks, industrial lifting systems, and medical equipment, lifting columns demand materials that combine strength, precision, and long-term reliability. Among available options, SUS316 stainless steel pipes have become a preferred choice for global buyers,especially in environments where corrosion resistance and durability are critical.
what is SUS316 Stainless Steel Pipe for Lifting Columns?
SUS316 stainless steel pipe for lifting columns is a precision-engineered tube made from molybdenum-containing austenitic stainless steel (SUS316), specifically designed for telescopic lifting systems such as electric height-adjustable desks, medical equipment, and industrial actuators. In lifting column applications, these pipes are typically manufactured with strict dimensional tolerances (±0.05 mm or higher precision), a surface roughness of Ra ≤ 0.8 μm, and excellent straightness to ensure smooth telescopic motion with minimal friction. In corrosive or high-humidity environments, their superior durability can extend service life by 20–30%.

SUS316 vs SUS304 for Lifting Columns: Which Should You Choose?
Unlike carbon steel or 304 stainless steel, SUS316 exhibits exceptional resistance to rust, pitting, and crevice corrosion in salt spray, acidic cleaning agents, and industrial atmospheric environments; this extends its service life by 3 to 5 times and significantly reduces maintenance requirements.
| 304 Stainless Steel (SUS304) | Most commonly used; suitable for indoor/dry environments; cost-effective |
| 316 Stainless Steel (SUS316) | High corrosion resistance; suitable for coastal/high-temperature/chemical industry environments |
| 316L Stainless Steel | Ultra-high corrosion resistance; suitable for extreme endangering environments (coastal, strong acid/alkali) |
