Direct from our Baoji facility to Poland. Every batch is CNC turned, thread rolled, stress relieved, and certified to meet high tensile DIN & ISO standards for road safety and racing performance.
The Tricity metropolitan area (Gdańsk, Sopot, Gdynia) presents a distinctive operating environment for high-performance motorcycles, custom roadsters, and endurance track machinery. Positioned directly on the Bay of Gdańsk along the southern coastline of the Baltic Sea, mechanical hardware is subjected to high ambient relative humidity, pervasive marine aerosol containing sodium chloride (NaCl) and magnesium chloride (MgCl2), and aggressive seasonal exposure to liquid road de-icing agents during northern Polish winters. Under these parameters, traditional zinc-plated carbon steel (Class 8.8 and 10.9) and cosmetic stainless steel (A2-70) quickly manifest localized crevice corrosion, hydrogen embrittlement, or cosmetic leaching.
As a leading titanium fasteners manufacturer situated in Baoji—China's recognized "Titanium Valley"—Zunvo Titanium provides Gdańsk importers, professional customizer ateliers, and racing components wholesalers with aerospace-grade Grade 5 (Ti-6Al-4V) hardware. By replacing OEM structural steel fasteners with hot-forged and CNC-turned titanium, mechanical integrity is substantially elevated while eliminating corrosive failure modes across safety-critical subassemblies.
Delivers a structural weight saving of ~44% against carbon steel, reducing unsprung rotational inertia on brake rotors and wheel hubs.
Matches and exceeds standard 8.8 carbon steel ratings while closely tracking high-tensile 10.9 ratings under proper pre-load torque engineering.
Spontaneous formation of an instantaneous, self-healing rutile-anatase TiO2 passive oxide layer completely prevents chloride pitting.
In competitive road racing at nearby facilities such as Autodrom Pomorze in Pszczółki or Tor Poznań, unsprung mass dictates suspension acceleration response and transient tire contact patch stability. Standard front brake rotor hardware on modern 1000cc superbikes accounts for over 280 grams of rotating, unsprung weight. Converting to our Ti-6Al-4V torx disc bolts drops this mass by over 120 grams directly at the wheel perimeter. This mass deduction reduces gyroscopic precession during high-speed directional changes through chicanes while minimizing damper thermal fatigue.
Our export catalog serves distinct market sectors across the Pomeranian Voivodeship, addressing both high-stress mechanical criteria and bespoke aesthetic standards demanded by regional workshops.
Brembo radial caliper bolts (M10x1.25x55/60mm) and disc rotor screws encounter extreme thermal flux during track sessions at Autodrom Pomorze. Grade 5 titanium maintains structural shear modulus up to 400°C without the micro-structural annealing observed in 7075 aluminum.
Custom workshops in Gdańsk Wrzeszcz and Gdynia customizing modern retros (BMW R nineT, Yamaha XSR, Triumph Thruxton) leverage our PVD-coated rainbow, midnight gold, and burnt-blue engine casing and subframe kits for zero-corrosion bespoke builds.
For touring and commuter bikes exposed year-round to Baltic onshore winds and winter brine, our M4–M6 pan head and flying-saucer self-tapping titanium fairing screws replace corroded zinc bolts, preventing plastic stress cracking and seizure.

The motorcycle aftermarket in Poland has witnessed rapid qualitative evolution over the past decade. Previously dominated by budget zinc-chromated hardware, the market has transitioned toward precision-machined, high-specification alternatives driven by three key factors:
1. Strict Roadworthiness Verification (TÜV & Badanie Techniczne): Mandatory vehicle inspections in Poland enforce stringent structural integrity rules. Fastener failures in suspension linkages, brake systems, or triple-tree clamps result in immediate roadworthiness revocation. Polish motorcycle specialty workshops require mill test certificates (MTCs) confirming mechanical traceability to avoid civil liability.
2. Direct Ocean Logistics via Baltic Hub (Port of Gdańsk): As Poland's premier maritime deepwater terminal, the Baltic Hub allows streamlined freight transit directly from East Asian industrial ports. Zunvo leverages this maritime corridor for palletized and containerized B2B volume orders, while maintaining express courier accounts (DHL Express / FedEx Priority) providing 3-to-5 day door-to-door transit for urgent custom batches directly to Tricity workshops.
3. Rise of Performance Electric Mobility: Tricity engineering hubs and light electric motorcycle (e-moto) builders actively optimize gross weight to extend lithium-ion battery range. Every kilogram eliminated from structural chassis fasteners translates to direct operational efficiency gains.
Founded in 2015 in Baoji, Shaanxi, Zunvo Titanium Products Co., Ltd. operates a 1,000–3,000 m² state-of-the-art manufacturing plant dedicated to titanium fasteners and bespoke CNC automotive parts. By controlling every stage from virgin ingot melting traceability to final surface treatment, we eliminate intermediaries and deliver genuine factory-direct value to European partners.
Full optical emission spectrometer checks ensuring strict adherence to Ti-6Al-4V chemical limits (Fe ≤ 0.30%, O ≤ 0.20%).
Micro-tolerancing on socket drive recess, bearing shoulder seats, and flange concentricity to eliminate tool slip and stress concentrations.
Quick-turn CAD/STEP drawing engineering review and 3-day sample dispatch for Polish custom shops validating specialized bracketry.
A proven international track record with verified 4.9/5 satisfaction ratings across Europe, North America, and racing teams worldwide.
A critical technical distinction in Zunvo motorcycle bolts is our strict thread-rolling protocol. Thread cutting interrupts the natural longitudinal grain flow of titanium bar stock, producing micro-notches at thread roots where fatigue fractures initiate under road vibration. Zunvo applies cold and warm thread rolling using precision carbide dies. This work-hardens the thread root and flank surfaces, induces beneficial compressive residual stresses, and increases cyclic dynamic fatigue endurance by more than 35% compared to conventionally cut fasteners.
Common questions addressed by our engineering and export departments for Polish motorcycle parts wholesalers, speed shops, and industrial procurement agents.
For catalog stock items, dispatch occurs within 24–48 hours via express air courier (DHL, FedEx, UPS) with customs clearance delivered directly to your workshop in 4 to 6 business days. Palletized bulk volume orders shipped via sea container into the Port of Gdańsk (Baltic Hub) typically take 28 to 34 days port-to-port.
Yes. All export shipments are accompanied by comprehensive commercial invoices with precise HS codes (e.g., 8108.90 for titanium articles), packing lists, and Certificates of Origin. We format export paper work to interface smoothly with Polish Urząd Celno-Skarbowy procedures and EU VIES intra-community standards.
Yes, provided specified engineering installation guidelines are observed. Ti-6Al-4V exhibits a tensile strength ≥895–950 MPa. While class 10.9 steel reaches 1,040 MPa, titanium's lower modulus of elasticity (114 GPa vs 210 GPa) allows superior cyclic elasticity. Fasteners must be torqued using a calibrated torque wrench with anti-seize paste (copper or moly paste) to counteract galling.
Unlike painted, lacquered, or powder-coated hardware, titanium anodizing is an electrochemical conversion process generating a transparent refractory oxide layer that interferes with light wavelengths. It contains no pigments and cannot flake or peel. For highest abrasive resilience, our PVD (Physical Vapor Deposition) Titanium Nitride (Gold) and DLC (Diamond-Like Carbon) coatings offer surface hardness exceeding 2000 HV.
For catalog parts, our MOQ begins at 100 sets or dozens. For bespoke custom designs according to customer drawings (CAD, DWG, STEP) or physical samples, our production line initiates tooling and CNC programming from as low as 100 pieces, enabling regional builders to prototype specialized bracketry without inventory burdens.
Yes. We offer complete OEM private label solutions, including in-house fiber laser etching for brand logos, thread pitch callouts, and batch numbers. We provide branded hanging blister packs, CNC anodized presentation boxes, or labeled compartment boxes ready for retail shelves in Polish dealerships.
Whether you require model-specific lightweight bolt kits, custom-machined rotor hardware, or containerized wholesale fasteners, our engineering team in Baoji delivers factory pricing with world-class quality assurance.
