Stainless steel is the most commonly used core material for hospital infusion chairs. 304 stainless steel is the basic model, while 316 stainless steel offers superior corrosion resistance due to the addition of molybdenum. Under normal use and proper maintenance, 304 stainless steel infusion chairs can last 10-12 years, while 316 stainless steel can extend this to 12-15 years. These materials possess strong resistance to rust and deformation, and are often used in special areas such as intensive care units and infectious disease departments. The key factor affecting the lifespan of stainless steel infusion chairs is maintenance; neglecting cleaning or improper installation may shorten their lifespan.
Cold-rolled steel powder-coated infusion chairs use cold-rolled steel sheets as the base material, with the surface treated with phosphate and then coated with medical-grade environmentally friendly powder, combining stability and economy. Under proper use, cold-rolled steel powder-coated infusion chairs have a lifespan of 8-10 years and are widely used in outpatient infusion rooms and general wards. Care should be taken to avoid scratching the powder coating with sharp objects, as exposed base material is prone to rust, potentially shortening its lifespan.
