Import 529r 22.5" S/S #304 10 Holes Truck Rear Wheel — Buy in Bulk from Supplier in Taiwan

The 529R 22.5 inch stainless steel #304 10-hole truck rear wheel is a disc wheel designed for heavy-duty commercial vehicle applications, fabricated from austenitic stainless steel grade 304 with 18 to 20% chromium and 8 to 10.5% nickel nominal composition per ASTM A240. The 22.5 inch diameter conforms to the standard rim size for Class 7 and 8 trucks, coaches, and tractor-trailers in North American, European, and Asian fleets, with the 10-hole bolt pattern typically corresponding to 335 mm pitch circle diameter and 26 mm diameter bolt holes for M22x1.5 or equivalent wheel studs. The #304 material selection provides corrosion resistance in salt-laden or high-humidity environments without painted or coated finishes, though it carries a weight penalty versus standard carbon steel wheels. A2A Manufacturing Co. produces this wheel at its Tainan facility, though specific production certifications or testing protocols are not detailed in the source data.

Stainless steel 304 in wheel applications offers a typical yield strength of 205 MPa and tensile strength of 515 MPa in the annealed condition, with work hardening during the spin-forming or deep-drawing process increasing yield to approximately 350 MPa in the rim section. The 10-hole design with evenly spaced bolting provides uniform clamp load distribution across the hub face, reducing the risk of fatigue cracking at bolt holes compared to 8-hole configurations under equivalent gross vehicle weight. The rim profile (likely 8.25 inch or 9.0 inch width for 22.5 inch diameter, though unconfirmed) determines compatible tyre sizes such as 295/80R22.5 or 315/80R22.5 common in regional and long-haul freight. Surface finish is typically 2B or polished on visible surfaces, with the disc and rim welds ground flush for stress relief.

Freight transport operators, bus fleet managers, and specialty vehicle builders source stainless steel wheels for corrosion-critical roles: chemical tankers with splash exposure, coastal routes, and vehicles with extended wash-down requirements. The absence of coating eliminates paint chipping and touch-up maintenance, though initial purchase price exceeds standard steel or aluminium. Buyers should confirm whether A2A supplies this wheel with valve stem, balance weights, or hub-piloted centre bore machining. Packaging for export typically involves stretch-wrapped pallet stacks with corner protectors; ocean freight from Kaohsiung port to Southeast Asian or Australasian destinations runs 5 to 12 days, while transpacific routes to West Coast North America require 14 to 21 days. No MOQ, pricing, or lead time is stated in the source material.

A2A Manufacturing Co. is located at No. 53 Yong-An 2nd Street, Tainan 709, Taiwan, positioning it within the southern Taiwan industrial corridor with access to Kaohsiung harbour, one of the island's primary container export gateways. The supplier carries a harbour trust tier with an imported designation, suggesting the listing profile was established through platform import rather than native registration, and shows a 0.00% response rate with zero average response hours. No factory size, year of establishment, employee count, or revenue figures are available in the source material. The company does not claim ISO 9001, IATF 16949, or specific automotive quality certifications in the provided data, though such credentials are common among Taiwanese automotive component manufacturers.

The product focus appears to be commercial vehicle wheels with material differentiation (stainless steel #304) as the primary value proposition versus commodity steel or forged aluminium competitors. The source description references ISO and SGS certifications without specifying scope, certificate numbers, or accredited testing laboratories, so buyers should request current certificate copies with validity dates. The mention of FOB and CIF shipping terms indicates export readiness, though specific incotem experience with your destination port should be confirmed. The absence of stated MOQ, price bands, or production capacity figures means buyers must negotiate these terms directly, with first orders likely requiring explicit sample approval before volume commitment.
