Import 524r 22.5" S/S #304 Truck Rear Wheel Cover — Buy in Bulk from Supplier in Taiwan

The 524R is a 22.5-inch rear wheel cover fabricated from stainless steel grade 304, supplied by A2A Manufacturing Co. from Tainan, Taiwan. This dimension corresponds to the standard rim diameter for heavy-duty commercial trucks and coaches, making the cover compatible with common 22.5-inch disc wheel configurations used in fleet transport. The use of AISI 304 austenitic stainless steel provides inherent resistance to atmospheric corrosion and road salt, which is critical for components exposed to wheel spray and underbody grit. The supplier describes the design as focused on durability and aesthetic enhancement, though no specific material thickness, weight, or finishing process is stated in the source data.

Stainless steel 304 contains 18-20 per cent chromium and 8-10.5 per cent nickel, offering a typical yield strength of 215 MPa and good formability for deep-drawn or spun wheel covers. In the truck aftermarket, 304-grade wheel covers are standard for operators prioritising corrosion resistance over the lower cost of 430-grade ferritic stainless or chromed ABS alternatives. The 22.5-inch sizing aligns with ISO rim standards for heavy commercial vehicles, specifically the 22.5 x 8.25 or 22.5 x 9.00 rim profiles. The listing mentions that the cover improves aerodynamics, which in this context typically means reduced turbulent airflow around the wheel hub, though buyers should request wind-tunnel or CFD data to validate any fuel-efficiency claims.

Fleet operators, truck body builders, and aftermarket distributors in the transport and logistics sectors represent the primary market for this product. The straightforward installation claimed by the supplier suggests a clip-on or bolt-fixed retention system, though the exact mechanism is not detailed. Buyers should confirm whether mounting hardware is included and whether the cover is designed for single rear wheels, tag axles, or dual-wheel configurations, as 22.5-inch rims appear in all three layouts. Certification status, specific MOQ, and pricing are absent from the listing and must be obtained directly from A2A Manufacturing Co.

A2A Manufacturing Co. is located at No. 53 Yong-An 2nd Street, Tainan 709, Taiwan. Tainan is a centre for metalworking and stainless-steel component manufacturing in southern Taiwan, with established supply chains for raw material, polishing, and surface treatment services. The supplier tier is marked as imported and trust tier as harbour, with response rate and average response hours both showing zero, indicating limited transaction history on this channel or incomplete profile data. Buyers should initiate contact to assess communication speed, technical competence, and willingness to provide factory information.

The listing does not state year of establishment, number of employees, annual turnover, or export experience. No specific client references, factory audit results, or quality management certifications are mentioned. The product description focuses on functional benefits rather than manufacturing credentials. Prospective buyers should request a company brochure, ISO 9001 or IATF 16949 certification status, and evidence of prior shipments to their region. Given that wheel covers for commercial vehicles may fall under vehicle equipment regulations in some jurisdictions, confirmation of regulatory compliance capability is a priority early in discussions.
