FAQ...
Do your stainless steel parts meet the assembly precision requirements of the automotive industry?
Profab Machine is equipped with high-precision CNC machining centers. We control the regular tolerance to ±0.01mm to meet the stringent assembly standards.
Are stainless steel fittings suitable for high temperature environments in the engine compartment?
Yes. Pofab uses stainless steel materials such as 304, 316 or 17-4PH. All upgraded material has excellent heat and corrosion resistance.
Will stainless steel components rust when exposed to road salt during winter?
304 stainless steel resists most forms of road salt corrosion under normal conditions. For vehicles operated in coastal or heavy snow regions, we recommend 316L stainless steel, which offers superior resistance to chloride-induced corrosion.
What wall thickness options do you offer, and can weight be reduced without compromising strength?
We offer multiple wall thickness options (such as 16-gauge / 1.5 mm). By using high-grade 304 or 316L stainless steel, thinner wall sections can be specified while maintaining higher strength.
