1.Extensive production experience: more than 20 years manufacturing experience for honed tube and chrome plated rod, in Australia, Thailand, Brazil, India, Iran, Indonesia, South Africa and other countries have long-term buyers.
2.Advanced production equipment: cold drawing machine, honing machine, skiving & roller burnishing machine, straightening machine, polishing machine, heat treatment furnace, grinding machine, etc. We have professional technicians do regular scheduled maintenance on these machines to guarantee them work well.
3.High quality raw material: our raw material mainly from some famous steel mills, such as TPCO, BAO STEEL, SHA STEEL, which are best and largest raw material manufacturer in China.
4.High precision: Honed Tube, inside surface roughness 02-0.4 um, straightness max 0.5/1000, strict tolerance DIN2391 H8. Skived & Roller Burnished Tube, inside surface roughness under 0.2 um, straightness max 0.2/1000, strict tolerance DIN2391 H8. Chrome Plated Rod, chrome layer 10 micron to 100 micron, strict tolerance ISO f7.
5.Strict quality control: we have professional in-house QC to inspect all products. We will do Chemical Composition Test, Mechanical Property Test, Dimension Inspect, Roughness Test, Chrome Layer Test and other tests in need before delivery.
6.Safe packing: an-rust oil on tubes and rods before delivery. Plastic caps on both ends to protect tube inside surface. Then be packed with seaworthy package or in wooden case.
