SS410 420 Lock Point, Hexagonal Support Adjustment Rivet High End Exterior Door Hardware
Stainless steel lock point, hexagonal support adjustment rivet - High-end door and window building hardware component
Material Selection Guide for Core Application Scenarios
I. Humid / Highly Corrosive Environments (Bathroom, Kitchen, Coastal Areas)
Long-term exposure to moisture, salt, and acid/alkaline cleaners can lead to material rust, corrosion, and aging, affecting both appearance and structural stability.
Preferred Materials:
304 Stainless Steel: High chromium and nickel content forms protective oxide film, suitable for ordinary humid environments
316 Stainless Steel: Enhanced with molybdenum for superior salt spray and acid/alkali resistance, ideal for coastal areas and high-exposure bathrooms
H59 Brass: High density and ductility with enhanced corrosion resistance through electroplating, excellent for functional and aesthetic components
Materials to Avoid:
201 Stainless Steel: Low chromium/nickel content with poor oxidation resistance, prone to rust and surface degradation
Zinc Alloy: Weak corrosion resistance, susceptible to oxidation and embrittlement in humid conditions
II. Load-Bearing Structural Parts (Door & Window Hinges, Corner Codes, Curtain Wall Connectors)
Core safety components requiring high strength, stability, and fatigue resistance while maintaining corrosion protection.
Preferred Materials:
Cold-Rolled Steel with Multi-Layer Electroplating: Dense texture with high strength, cost-effective for most indoor/outdoor applications
304 Stainless Steel: Combines high strength with excellent corrosion resistance, ideal for outdoor and high-durability applications
Core Parameter Requirements:
Strength ≥ 8.8 (bolt-type load-bearing parts)
Thickness ≥ 2.5 mm for enhanced structural rigidity and fatigue resistance
III. Lightweight / Decorative Parts (Door & Window Pulleys, Handles, Ceiling Decorations)
Components prioritizing lightweight design, aesthetic appeal, and basic durability without heavy load-bearing requirements.
Preferred Materials:
Aluminum Alloy: Low density with good ductility and wear resistance, surface treatments available for various finishes
Zinc Alloy (Non-Load-Bearing): Excellent castability for complex shapes with strong decorative potential after electroplating
Important Note:
Zinc alloy should only be used in non-load-bearing applications due to low strength characteristics.
IV. Outdoor / General Engineering Parts (Bolts, Anchors, Steel Wire Meshes)
Applications requiring weather resistance, universality, and balanced cost-effectiveness for large-volume usage.
