Engineered to rigorous global benchmarks including CE, NFRC, Miami-Dade NOA, and AS2047 specifications.
A global leader in high-performance structural entry systems, customized architectural doors, and multi-regional certified facade components.
Zhejiang Shieldoors Security Technology Co., Ltd. was established in 2016 and is located in an expansive 45,000 m² state-of-the-art production base. Building on 10 years of industry leadership and 6 years of international trade experience, the company generates an annual export revenue reaching USD 42,000,000. Our global supply infrastructure empowers commercial developers, facade engineers, and architectural retail syndicates across demanding international markets.
Our commitment to operational excellence is maintained through rigorous ISO9001-certified quality control and comprehensive third-party product testing protocols, including CE marking under EN 14351-1, UL fire-rated certifications, and high-velocity hurricane-impact validations (Miami-Dade NOA). A dedicated quality inspection team of 78 QC specialists ensures that every front door and facade unit meets stringent safety, thermal, and structural load criteria. Supported by a robust ecosystem of 1,400 supply chain partners, our trade background spans direct export, project bidding, and integrated B2B supply chain operations across North America, Europe, Australia, and Southeast Asia.
Navigating the complex mechanical, thermal, and safety prerequisites for exporting architectural entry doors to the European Single Market.
Selecting a CE certified front door supplier is not merely a box-checking exercise for European compliance; it is a fundamental engineering requirement under the Construction Products Regulation (CPR Directive No 305/2011). The mandatory harmonized standard EN 14351-1 (Windows and external pedestrian doorsets) governs the Essential Characteristics that external doors must demonstrate before receiving the CE mark and Declaration of Performance (DoP).
Key Takeaway for B2B Importers: European law mandates Assessment and Verification of Constancy of Performance (AVCP) System 1 or 3 for safety components and emergency escape doors. Sourcing from non-certified facilities risks immediate customs seizures, legal liability, and costly job-site replacements.
A compliant front door must demonstrate validated performance across several standardized testing parameters:
Evaluation of physical break-in resistance rated from RC2 to RC5. Testing incorporates static pressure testing (up to 6 kN load), dynamic impact testing with pendulums, and manual burglary attempt simulation using specified toolsets.
Calculation and testing of Ud-values (Door Thermal Transmittance). High-performance thermal-break aluminum profiles combined with Low-E double or triple glazing achieve Ud ratings as low as 0.8 to 1.1 W/(m²·K), meeting Passive House targets.
Tested under EN 12208 (Watertightness up to Class E1050) and EN 12207 (Air Permeability up to Class 4). Multi-point EPDM gasket seals prevent wind-driven rain penetration under pressure differentials up to 600 Pa.
| Testing Parameter | European Standard (CE) | North American Standard | Shieldoors Factory Benchmark |
|---|---|---|---|
| Structural Wind Load | EN 12210 (Class C5 / 2000 Pa) | ASTM E330 / TAS 202 (DP70+) | Exceeds Class C5 / DP80 Design Pressure |
| Thermal Insulation (Ud/U-Factor) | EN ISO 10077-2 (Ud ≤ 1.2 W/m²K) | NFRC 100/200 (U-factor ≤ 0.22) | Ud = 0.85 W/m²K (Thermal Break Polyamide) |
| Impact / Intrusion Resistance | EN 1627 (RC2 / RC3 / RC4) | ASTM E1886 / TAS 201 (Large Missile) | RC3 Standard / Pass 9-lb Missile Impact |
| Acoustic Insulation (Rw) | EN ISO 717-1 (Rw ≥ 38 dB) | ASTM E90 (STC ≥ 40) | Rw = 42 dB (Acoustic Laminated Interlayers) |
How Zhejiang Shieldoors leverages an ecosystem of 1,400 supply partners to deliver institutional-grade entrance systems at unmatched economies of scale.
China's architectural door and window manufacturing ecosystem has evolved from high-volume assembly to advanced structural engineering and material science customization. At the epicenter of this transformation, Zhejiang Shieldoors Security Technology Co., Ltd. combines vertical integration with specialized supply chain clusters.
Supported by 350 skilled R&D engineers, our facility launched over 450 new product designs last year alone. Our enterprise framework connects raw extrusion mills, high-durability hardware foundries, multi-layer glass processors, and surface finishing facilities directly to our central 45,000 m² assembly complex.
Direct sourcing of high-grade virgin billet aluminum alloy with precision wall thicknesses (2.0mm to 3.0mm). Thermal break systems utilize imported German Technoform polyamide strips (PA66GF25) for extreme structural stability and U-value reduction.
Seamless mechanical integration with Tier-1 international hardware hardware like Hoppe, Siegenia, GU, and Winkhaus, alongside custom heavy-duty multi-point stainless steel security locks engineered for smart biometric access control.
Equipped for Fluorocarbon PVDF coating, AkzoNobel powder coating, anodizing, and authentic wood-grain heat-transfer technology designed to withstand 3,000+ hours of continuous salt-spray testing without fading or peeling.
From raw aluminum extrusion to robotic packing: 8 standardized production stages overseen by 78 dedicated QC specialists.
Engineered architectural door configurations designed to meet specific regional environmental stressors and structural building mandates.
High-Velocity Hurricane Zone (HVHZ) compliance requiring Miami-Dade NOA and Florida Building Code approvals. Triple-pane laminated impact glass and heavy-gauge reinforced aluminum stiles designed for coastal storm resilience.
Strict adherence to EN 14351-1 standards with Ud thermal limits lower than 1.0 W/(m²·K). Thermal-break profiles with multi-stage EPDM weather gaskets engineered for severe cold climate thermal retention.
Fabricated in compliance with AS2047 physical performance requirements (deflection, water penetration, ultimate limit state) and rated under WERS for optimal solar heat gain coefficients (SHGC).
