Import Bicycle Top Tube — Buy in wholesale FOB from Supplier in Taiwan

This bicycle top tube is an AL 6061-T6 aluminum alloy structural component manufactured by Thai Shun Industrial Co., Ltd in Taichung City, Taiwan. The tube is engineered for integration into bicycle frames, specifically positioned as the horizontal or near-horizontal member connecting the head tube to the seat tube. The supplier specifies the material as AL 6061-T6, a precipitation-hardened aluminum alloy with magnesium and silicon as primary alloying elements, heat-treated to the T6 temper for maximum strength. The source data lists tube drawing, tube tapering, rotary swaging, stamping, tube bending, and hydroforming among the available processing methods, allowing frame builders to specify geometry beyond straight round profiles.

AL 6061-T6 is the most widely specified aluminum alloy in mid-range and performance bicycle frames, offering a tensile strength of approximately 290-310 MPa and yield strength of 240-270 MPa in standard bar stock. Thai Shun subjects this material to tube drawing for dimensional precision, then tapering and hydroforming to create variable cross-sections that improve stiffness-to-weight ratios and aerodynamic profiling. The T6 temper (solution heat-treated and artificially aged) provides consistent mechanical properties across production batches. Rotary swaging can produce butted walls (varying thickness along the tube length), though the listing does not confirm standard butting profiles such as single-butt, double-butt, or triple-butt configurations. Surface treatment options typical for this product category include anodizing (Type II decorative or Type III hardcoat) and shot-peening for fatigue-life enhancement, neither of which is explicitly committed in the source description.

This top tube targets bicycle manufacturers, custom frame builders, and OEM suppliers who require starting stock for welded or bonded frame construction. The hydroforming capability is particularly relevant for brands developing aerodynamic road or gravel frames with shaped tube profiles. Thai Shun holds organic-tier supplier classification and voyage-tier trust credentials, with a physical address in Dajia District, Taichung, a region dense with precision metalworking and cycling-industry supply chains. The supplier does not publish MOQ, price per metre, standard lead time, or mill source certification in the provided data. Buyers should request a detailed quotation including dimensional tolerances, straightness specifications, and any available mechanical test reports from the certifying mill.

Thai Shun Industrial Co., Ltd is based at 1F., No.46, Kaiyuan Road, Dajia District, Taichung City, Taiwan. The company holds organic-tier supplier classification and voyage-tier trust designation. The response rate is recorded at 0.00 percent with zero average response hours, suggesting that platform-tracked reply data is not yet available or not yet populated for this account. The address places Thai Shun within Taichung's Dajia District, an area known for bicycle component manufacturing and metal fabrication supply chains that support Taiwan's global cycling industry.

The supplier profile does not state year of establishment, employee count, factory certification, annual production capacity, or named OEM clients. No ISO 9001, ISO 14001, or specific mill certification numbers are provided in the source data. The listing emphasizes precision engineering and hydroforming capability, positioning Thai Shun as a component supplier rather than a finished-frame manufacturer. Buyers should request company registration documents, quality management system certificates, and sample tubes for metallurgical verification before committing to production-volume orders. The absence of published MOQ or lead-time data means all commercial terms must be negotiated directly.
