2. What corrosion resistance or load strength test reports are available?

Taiwan Sheh Kai Precision provides several test reports to validate the performance of its Bi-metal screws:

●Corrosion Resistance Testing:

Salt Spray Test: Simulates harsh environmental conditions to evaluate the screws' resistance to corrosion in high-salinity and humid environments. Test results show compliance with or surpass international corrosion resistance standards.
Long-term Environmental Simulation Testing: Assesses the screws’ durability and corrosion resistance in coastal and industrial environments.

●Load Strength Testing:

Tensile Strength Test: Ensures the screws can withstand high stress, especially in heavy-load construction applications.
Shear Strength Test: Validates the screws’ structural stability at connection points, suitable for demanding load-bearing and fastening applications.
Torque Test: Measures the screws’ torque performance to ensure stable installation without damage during the fastening process.

These standards and test results demonstrate the superior quality of Taiwan Sheh Kai Precision's Bi-metal screws and their reliability in high-end applications, such as construction, energy, and industrial projects.
