Patent Screws and Building Standards: Navigating CNS, ISO, and EN Compliance in Construction

In the construction industry, safety and reliability start with the smallest details. Screws and fasteners may seem minor, yet they carry the critical responsibility of holding entire structures together. For international buyers and procurement professionals, compliance with building standards is not just a technical detail—it is a safeguard against legal risks, costly rework, and, most importantly, safety failures.

At Fong Prean Industrial, we specialize in developing patent screws for construction applications, designed from the ground up to comply with the world’s most rigorous standards, including CNS, ISO, EN, ASTM, and JIS.

Why Standards Matter in Construction Fasteners

Unlike general industrial components, building fasteners are governed by strict regulations:

  • EN 14592 (Europe) – Specifies requirements for timber construction fasteners such as screws and nails.

  • ETA/EAD (European Technical Assessment) – A requirement for CE marking in structural applications.

  • ASTM/AISI (U.S.) – Commonly used for structural steel and building materials.

  • CNS (Taiwan) – Ensures compliance with national safety standards.

  • ISO (International) – Provides global alignment on dimensions, tolerances, and strength classes.

For procurement teams, overlooking these standards can expose projects to contract breaches, liability issues, and safety hazards.

The Compliance Advantage of Patent Screws

Patent screws provide distinct advantages for construction projects:

  1. Pre-certified Design – Developed with geometry and materials already aligned to EN, ASTM, and ISO standards.

  2. Structural Reliability – Enhanced holding power and resistance to withdrawal, critical for timber and steel applications.

  3. Corrosion Resistance – Surface treatments engineered for outdoor and long-term exposure.

  4. Simplified Procurement – A single product line that reduces inventory complexity while meeting multiple markets’ needs.

Fong Prean’s Commitment

Our mission is to provide OEM/ODM fasteners that exceed construction standards worldwide. We achieve this through:

  • Certified material sourcing

  • Precision production technologies

  • Rigorous in-house and third-party testing

  • Tailored fastener designs for specific building applications

For buyers, this translates into confidence that every screw is compliant, reliable, and globally market-ready.

Conclusion

In construction, every connection matters. Patent screws that comply with CNS, ISO, EN, and ASTM standards offer procurement teams the assurance they need to avoid risks and deliver safe, long-lasting projects.
