Taiwan upholds stricter quality standards, particularly in material sourcing and manufacturing consistency.

Unlike neighbouring countries, where recycled steel is commonly used — often with uncertain composition and substandard quality — we source high-grade steel to ensure durability and reliability.

We also emphasize consistent thread tensile strength, proper torque specifications, and precise clamping force to guarantee performance and safety.

Additionally, our CASS (Copper Accelerated Acetic Acid Salt Spray) testing standards exceed those of many suppliers, which typically range from 48 to 72 hours only.
(Please review more info under TESTING & SOLUTIONS below)

We use high-strength, cold-forged 7075 aluminum alloy, renowned for its durability, and long-lasting performance.

Our lugs typically require a torque of 100-180Nm, depending on the product and vehicle specifications.
For optimal clamping force, we recommend following the vehicle manufacturer’s guidelines.

We use low to medium carbon steels for lugs and bolts, they're heat-treated to achieve a hardness Grade of 8 to 12. The hardness varies by application, with aluminum alloys and steel products treated accordingly for optimal performance.

Our products feature thread tensile strengths ranging from Grade 8 to 12.9, tailored to meet client-specific applications and requirements.

We adhere to strict CASS (Copper Accelerated Acetic Acid Salt Spray) testing standards, ensuring durability across various finishes:

• ED & Zinc: 96+ hours
• Chrome: 144+ hours
• Black Chrome: 196+ hours

All finishes withstand these durations without significant corrosion.
