Client Feedback
What Buyers Say
We source rod ends and clevis for suspension components. Profab's tolerances are tight and the material certs are legit. We verified them with our own XRF gun on the first order. Now on our fourth order and no issues.
Michael Turner
Purchasing Manager · Automotive OEM Supplier, USA
We needed to upgrade the material grade on a linkage. Profab reviewed the specs, recommended a better alloy option, and the final parts performed exactly as expected in our environment. They clearly understand materials and industrial applications. Good factory.
Isabella Chen
Project Engineer · Food Equipment Manufacturer, Australia
Marine hardware for our charter fleet. Everything in 316L, mirror finish where visible. The cleats and turnbuckles have been in saltwater service for two seasons now — no pitting, no discolouration. Worth the price.

FAQ
Common Questions
Not seeing your question? Email us at [email protected] and we typically reply same day.
What is your minimum order quantity?
There is no hard minimum. We regularly run prototypes of 100 pieces and full production runs of 10,000+. Pricing tiers at 100, 500, and 1000 pieces. We show all tiers in our quotes so you can see where the economics shift.
What stainless grades can you supply?
We regularly machine 303, 304, 304L, 316, 316L, 17-4PH, 2205 duplex, 2507 super duplex, 410, and 430. If you need a grade not listed, just contact our team.
Can you work from my drawings or CAD files?
Yes. Send DXF, DWG, STEP, IGES, or PDF with dimensions. If you only have a sample part and no drawing, we can reverse-engineer it for an additional fee. We review all drawings for manufacturability before quoting.
When should I use 304 vs 316?
304 is the go-to for indoor and mildly corrosive environments. It is cheaper and machines easily. 316 adds molybdenum which resists chloride attack, so use it for anything exposed to saltwater, coastal air, food-grade cleaning chemicals, or marine environments. The cost difference is typically 15–25%.
What surface finishes do you offer?
Electropolishing; Sandblasting / Bead Blasting; Mirror Polishing; Powder Coating; Passivation; Brushing (Satin Finish); Black Oxide / Blackening (on stainless steel alloys that support it).
What payment methods do you accept?
PayPal, Bank Transfer (T/T), and Alibaba platform.
