Key Benefits & Target Applications

Core Hardware Advantages

  • Economical B2B Specification: Aluminum construction provides a highly cost-effective alternative to brass, making it ideal for high-volume bids, public works, and large-scale property developments.
  • Massive 30 mm Wide-Angle Head: The oversized 30 mm head diameter maximizes light capture and provides an exceptionally wide, comfortable viewing experience for residents.
  • Anodized Gold Aluminum Finish: The anodizing process creates a highly durable surface layer that protects against wear, minor scratches, and oxidation while delivering an attractive metallic gold look.
  • Tamper-Resistant 16 mm Tube: The thicker 16 mm tube diameter provides high physical shear strength, reinforcing the core structure against mechanical tampering.

Primary Application Environments

  • Large-Scale Housing Developments: Highly favored by developers of high-density apartments, public housing, and tract homes due to its competitive pricing and reliable performance.
  • Standard Residential Entrance Doors: Fits a wide array of standard-thickness wood, composite, or steel-clad entry doors.
  • Lightweight Composite Doors: The low density of aluminum minimizes stress on lightweight hollow-core or composite doors while ensuring tight installation.
  • Commercial Real Estate: Suitable for standard office and facility entryway doors requiring functional security within a strict budget.

Our optical engineering history:
Our Chairman, Mr. Shao Wencai, is an experienced optical designer who was deeply involved in developing China’s first-generation door viewer in 1978. He patented a 180-degree wide-angle door viewer in 1990, securing a national patent. He later designed a dual-purpose door viewer in 1998, followed by an enhanced optical door viewer system in 2006.

Our aluminum and brass door viewer series undergo strict internal testing to meet international quality and safety benchmarks.

Frequently Asked Questions

Aluminum door viewers provide a highly economical and lightweight alternative, which significantly reduces procurement costs for large-scale construction projects and limits the structural weight load on composite doors.

GA stands for Gold Aluminum, which is achieved through a professional anodizing process. This electrochemical treatment creates a hard, corrosion-resistant outer layer that resists flaking, scratching, and oxidation.

Yes. We manufacture matching anodized aluminum privacy covers Model F5016G and extension tubes Model F5016J designed specifically for the 5016 series.
