High-weatherproofing, high-wind-load custom anchor bolts, sliding channel nuts, and anti-vibration fasteners for solar tracking systems, utility-scale power plants, and rooftop solar installations.
Sea-water and chemical corrosion-resistant custom flange bolts, U-bolts, and heavy-duty expansion anchors made of premium SS316 and Duplex Steel.
Grade 12.9 ultra-high strength custom shoulder screws, drive components, and precision micro fasteners designed for high fatigue life under extreme vibration.
Corrosion Resistance: Dacromet, Geomet, Hot Dip Galvanized (HDG) – Easily passes 480 to 1000-hour salt spray tests, perfectly weathering harsh desert and offshore environments.
Standard Finishes: Zinc Plating, Anodizing (Aluminum), Passivation (Stainless Steel), Black Oxide.
Strict Inspection Process & Advanced Equipment
We fully understand that for non-standard custom parts, “material traceability” and’dimensional accuracy” are your top priorities. To guarantee absolute compliance, we operate arigorous 4-stage quality control system covering everything from raw materials to final shipping.
Test Items: Chemical composition analysis, heat number verification, raw material hardness, wire/bardiameter tolerance.
Equipment: Optical Emission Spectrometer (OES), Rockwell/Leeb Hardness Testers.
Standards: 100% heat-number verification matching the raw mill’s certificate (MTC) to preventmaterial mixing.
Test Items: First Article Inspection (FAl), critical dimensional tracking, thread pitch/major diameter,concentricity, and metal stamping spring-back control.
Equipment: 2D Optical Measuring Projectors, Digital Micrometers, Vernier Calipers, High-PrecisionThread Go/No-Go Plug & Ring Gauges.
Standards: FAl clearance before any production run, followed by routine QC patrols every 30 minutesto prevent dimensional drift.
Test Items: Tensile strength, yield strength, proof load, hardness grading, coating/plating thickness,and salt spray corrosion resistance lifetime.
Equipment: Universal Tensile Testing Machine, Metallurgical Microscope, X-Ray/Magnetic CoatingThickness Gauge, Corrosion Salt Spray Testing Chamber.
Standards: Mechanical properties complying with ISO 898-1/ASTM A370; surface treatment testingunder Neutral Salt Spray (NSS, ISO 9227) up to 480H-1000H.
Test Items: 100% visual/dimensional sorting (eliminating thread-missing, burrs, or broken-pinmixing), final packaging sealing, and label/marking verification.
Equipment: High-Speed Optical CCD Sorting Machine, Digital Torque Wrench.
Standards: 100% sorting via optical CCD machines for high-precision items to secure AQL 0.65shipment quality levels.
