Architectural Door & Window Hardware Selection

I. Core Principles for Selecting Door & Window Hardware

1. Commercial vs. Residential: Key Differences & Selection Guidelines

2. General Hardware Selection Criteria

• Material: Load-bearing parts prefer 304/316 stainless steel and high-strength alloy steel; decorative parts may use zinc alloy or eco-friendly aluminum alloy.
• Strength: Commercial fasteners ≥ Grade 8.8; residential fasteners ≥ Grade 4.8; rivets must meet tensile-shear strength and fatigue resistance requirements.
• Precision: Dimensional tolerance ≤ ±0.02mm to ensure assembly consistency and reduce air and water leakage.
• Corrosion Resistance: Surface treatments including galvanizing, zinc-nickel alloy and fluorocarbon coating; salt spray test ≥ 500h (commercial) / ≥ 200h (residential).
• Process: Standard parts prioritize cold heading + thread rolling; special / customized parts use machining to balance performance and cost.

III. Situo Hardware: One-Stop Solution for Door & Window Rivets

1. Core Process Advantages: Cold Heading Primary, Machining Supplementary

• Cold Heading (for mass production & standard parts)
  
  
  • Performance: Continuous grain structure with work hardening, 30% higher strength, better fatigue and vibration resistance, meeting long-term stability requirements.
  • Efficiency: Automated high-speed forming, 60–800 pieces per minute, material utilization over 95%, cost reduced by 30%–50%, suitable for mass engineering production.
  • Precision: Near-net shape forming, tolerance ≤ ±0.01mm, extremely high batch consistency, compatible with automated assembly lines.
  • Applications: Standard blind rivets, sealed rivets, structural rivets, high-strength fasteners for commercial frames and curtain wall connections.
  
  
• • Flexibility: Capable of processing complex special-shaped, non-standard, multi-hole and special-flange rivets to meet residential customization and special engineering design needs.
  • Precision: Single-piece customization with ultra-high precision, suitable for special materials such as titanium alloy and high-temperature alloys for small-batch prototyping.
  • Applications: Special decorative rivets, special structural rivets, small-batch customized fasteners for residential hardware and high-end custom doors and windows.
