View Product DetailsA Comprehensive Industry Whitepaper on High-Performance Fenestration, Security Compliance, and Thermal Efficiency Standards
In modern architectural design, the double entry door system serves as a critical structural node linking exterior building facades with interior thermal envelope zones. Globally, the demand for high-security, thermally broken, and CE-marked double doors has experienced unprecedented growth. Fueled by stringent international building codes (such as Europe’s Energy Performance of Buildings Directive - EPBD, and North American NFRC/IECC benchmarks), commercial construction projects now mandate structural integrity that goes far beyond aesthetic appeal.
The global industrial and commercial door sector is undergoing a rapid transition driven by four key macro vectors:
Industrial scale, rigorous quality assurance, and global export capabilities driving security and fenestration excellence worldwide.
Established in 2003, Steelwar Entry Systems Co., Ltd. operates a large-scale 40,000 m² manufacturing plant specializing in high-security exterior entry doors. With 21 years of continuous industry experience and 9 years of global export capabilities, the company generates $35 million in annual export turnover. Steelwar focuses on key markets across North America, the Middle East, and Eastern Europe, primarily supplying building material distributors, security door stockists, and commercial construction contractors.
Supported by a solid trade background and a network of 1,100 supply chain partners, Steelwar maintains strict product reliability. Quality control is managed by a team of 50 QC specialists who execute dynamic impact resistance testing, automated frame tolerance checks, and corrosion-resistant coating audits. The company's engineering strength is backed by 75 R&D engineers who introduced 230 new product models last year. Custom options include ballistic steel cores, multi-point smart lock integration, customized RAL color finishes, and bespoke frame depths.
From CAD engineering to dynamic load testing, every double entry door profile undergoes multi-stage technical inspection.

Deciphering European Norm (EN) Requirements for Construction Products Regulation (CPR 305/2011)
For double entry doors to earn and maintain valid CE Certification under standard EN 14351-1, manufacturers must subject representative door assemblies to rigorous third-party laboratory verification (Notified Body testing). The CE mark certifies that the double entry door assembly meets essential health, safety, and environmental protection performance metrics.
| Test Parameter | Harmonized Test Standard | Performance Classification Range | Steelwar Engineering Standard |
|---|---|---|---|
| Burglar Resistance | EN 1627 / EN 1630 | Class RC1 to RC6 | RC2 - RC4 (Ballistic & Crowbar Resistance) |
| Air Permeability | EN 12207 | Class 1 (Low) to Class 4 (High) | Class 4 (Hermetically Sealed EPDM Gaskets) |
| Watertightness | EN 12208 | Class 1A to Class 9A / Exxx | Class 9A (Up to 600 Pa Continuous Water Pressure) |
| Wind Load Resistance | EN 12210 | Class C1 to Class C5 | Class C5 (High-Rise Wind Shear Resistance) |
| Thermal Transmittance | EN ISO 10077-1/-2 | $U_d$ Value ($\text{W}/(\text{m}^2\cdot\text{K})$) | $U_d \le 0.85 \, \text{W}/(\text{m}^2\cdot\text{K})$ (Passive House Standard) |
| Acoustic Attenuation | EN ISO 717-1 | $R_w \, (C; C_{tr})$ in dB | $R_w = 42 \text{ dB} - 48 \text{ dB}$ Sound Reduction |
Tailored architectural implementations across distinct geographic climate zones and building typology demands.
Designed specifically for coastal zones subject to hurricane winds and salt spray corrosion (e.g., Caribbean, Florida, Middle East coasts).
Optimized for North American and Northern European climates where interior heat retention is paramount during freezing sub-zero conditions.
Engineered for high-frequency usage areas like hotel lobbies, corporate headquarters, and luxury residential tower entrances.
The next decade of fenestration technology: Intelligence, Ultra-Efficiency, and Structural Automation.
As smart city frameworks evolve and net-zero energy building (NZEB) mandates take effect globally, Steelwar Entry Systems is spearheading next-generation double entry door research across three specialized domains:
Transitioning from standard double/triple glazing to 8mm ultra-thin Vacuum Glass panels capable of achieving $U_g = 0.40 \, \text{W/(m²·K)}$, reducing door leaf weight while doubling thermal performance.
Embedding smart sensors directly within the door core to monitor structural flexure, humidity, air leakage, and attempted forced entry in real-time, instantly reporting to building management systems (BMS).
Replacing traditional foam insulation with bio-based high-density polyurethane and eco-friendly expanded basalt wool cores to meet carbon neutrality standards across Europe and North America.
Expert answers to critical procurement, technical specification, and compliance questions regarding double entry doors.
CE Certification under standard EN 14351-1 guarantees that the complete double entry door assembly (including frame, glass, hinges, gaskets, and locking systems) has underwent empirical laboratory testing. It validates performance metrics such as burglar resistance (EN 1627), wind load resistance (EN 12210), air permeability (EN 12207), watertightness (EN 12208), and thermal overall $U$-value calculation (EN ISO 10077).
Our double entry doors utilize a multi-chamber thermal break system featuring Polyamide PA66 GF25 insulation strips. These structural insulation barriers break the physical contact between the interior and exterior metal profiles. Combined with high-density polyurethane core infill and triple-pane Low-E insulated glass units (IGUs) filled with 90% Argon gas, thermal transmittance ($U_d$) is minimized to as low as $0.85 \, \text{W/(m²·K)}$.
Yes. Supported by our 75 R&D engineers, Steelwar offers custom ballistic steel core reinforcements integrated inside the door leaf. We manufacture double entry doors capable of reaching EN 1627 RC2 to RC4 security standards as well as customizable ballistic protection levels matching UL 752 / EN 1063 standards upon project-specific requests.
We provide fully customizable frame depths ranging from 70mm up to 220mm to accommodate varying wall construction thicknesses (e.g., ICF, concrete block, timber frame, curtain wall integration). Finishing options include over 200 RAL powder-coated colors, wood grain heat-transfer sublimation, anodized metallic finishes, and fluorine-carbon (PVDF) high-durability coatings for marine environments.
With our 40,000 m² manufacturing plant, 1,100 supply chain partners, and 50 QC specialists, standard project production lead times range from 25 to 35 business days following CAD shop drawing approval. We handle bulk containerized shipping for commercial distributors, stockists, and direct contractors across North America, the Middle East, and Eastern Europe.
