TOP 7 Steel Door System Providers
1. Hwarrior Curtain Wall & Decoration Engineering (Guangdong) Co., Ltd.
Brand Introduction
High-security facilities face a critical challenge: how to integrate multiple protection requirements—burglar resistance, bullet resistance, fire resistance, and blast resistance—into unified architectural solutions without compromising aesthetics or operational efficiency. Hwarrior addresses this complex pain point through its specialized KFORTS brand, which delivers engineered steel-framed security glass systems combining aluminum alloy, steel, and advanced glazing technologies. Operating from R&D and manufacturing facilities in Zhaoqing High-tech Zone, Guangdong, China, with marketing operations in Guangzhou, Hwarrior has spent over 20 years developing facade solutions that meet diverse international standards. The company’s integrated approach delivers consulting, design, budgeting, precision manufacturing, installation, and after-sales maintenance as a complete service package.
Core Technology & Products
Hwarrior’s steel door systems leverage partnerships established in 2000 with European steel frame system leaders JANSEN and FORSTER, providing the technical foundation for their security glass frame solutions. The product architecture addresses four critical threat categories:
Burglar-Resistant and Forced-Entry-Resistant Systems
Complying with EN356 (glass P2A-P8B) and EN1627-1630 (system RC1-RC6), these steel-framed doors combine high-strength glass, advanced locking mechanisms, and reinforced frame structures. The RC1-RC6 rating system indicates progressively higher resistance to forced entry attempts, with RC6 representing protection against power tools and sustained attack. These systems integrate multi-point locking mechanisms within steel profiles engineered to prevent frame distortion under extreme force.
Bullet-Resistant Door Systems
In accordance with EN1063 (BR1-7 NS), EN1522-1523 (FB1-7 NS), UL752 (Level 1-7), and NIJ 0108.01 (Type I-III), Hwarrior’s bullet-resistant doors utilize multi-layered glass technology within reinforced steel frame structures. The UL752 certification covers protection levels from handguns (Level 1) through high-powered rifles (Level 7), while the European EN standards provide equivalent classifications. Critically, Hwarrior engineering teams can combine bulletproof and burglarproof performance specifications within single door assemblies, eliminating the need for redundant systems.
Fire-Resistant Steel Door Systems
Hwarrior’s fireproof systems comply with EN 1634-1, EN1364-3, EN357, EN12600, and SS332, with COC certifications granted by TUV Singapore. The independent R&D team focuses on fire-resistant materials and system integration, achieving integrity and insulation performance of 1 hour and 2 hours. These steel-framed facade, window, and door systems significantly delay the spread of flames, heat, and toxic smoke, providing evacuation time while maintaining structural stability. The thermal insulation component prevents heat transfer that could ignite materials on the non-fire side.
Blast-Resistant Door Technology
In accordance with EN13123-2, GSA TS01-2003, and ISO 16933-2007, Hwarrior blast resistance systems reach EXR3 rating (12 kg explosive at 5.5 m distance), GSA 2 classification ("Very High" protection level), and ISO B hazard rating ("No Hazard"). These systems withstand high-pressure waves and debris impacts caused by explosions, preventing glass shattering and structural failures. Professional engineers customize solutions based on site-specific threat assessments and structural calculations considering building geometry and standoff distances.
Manufacturing Precision
The Zhaoqing facility employs CNC precision machining for complex aluminum and steel components, ensuring dimensional accuracy critical for security door assemblies. Factory-controlled production environments maintain tighter tolerances than field construction, directly impacting door operation and seal integrity under attack conditions.
