Established in 2003, Steelwar Entry Systems Co., Ltd. operates a state-of-the-art 40,000 m² manufacturing facility specializing in high-security exterior entry doors, reinforced aluminum door frames, and architectural glazing systems. With over 21 years of continuous industry expertise and 9 years of global export capabilities, Steelwar has built an international reputation generating over $35 million in annual export turnover. Our strategic footprint serves tier-one markets across North America, the Middle East, and Eastern Europe, catering to commercial construction contractors, building material distributors, and security door stockists.
Driven by rigid manufacturing standards, Steelwar leverages an extensive network of 1,100 supply chain partners to ensure raw material consistency and competitive component sourcing. Quality assurance is maintained by an in-house team of 50 Quality Control (QC) specialists who execute automated frame tolerance checks, dynamic impact-resistance tests, and rigorous corrosion-resistant coating audits. Innovation remains core to our business: our engineering division comprises 75 R&D engineers who introduced 230 new product designs last year alone. Our specialized OEM/ODM capabilities encompass custom ballistic steel inner cores, multi-point electronic smart lock integration, dynamic powder-coated RAL finishes, and tailored profile extrusions engineered to meet demanding structural load requirements.
An in-depth technical analysis of profile geometry, extrusion alloys, thermal break integration, and forced-entry prevention mechanisms.
The structural integrity of a reinforced aluminum door frame depends fundamentally on alloy metallurgy. Steelwar utilizes premium 6063-T6 and structural 6061-T6 aluminum alloys. 6063-T6 offers superior surface finish quality for anodizing and complex multi-chamber extrusions while delivering a minimum tensile strength of 205 MPa and yield strength of 170 MPa. For heavy-duty commercial applications and bullet-resistant assemblies, 6061-T6 is specified, offering yield strengths exceeding 240 MPa. Frame walls are extruded at structural thicknesses ranging from 1.8mm up to 3.0mm, preventing warping under extreme wind loads and violent physical impacts.
Unreinforced aluminum frames can yield to mechanical prying and dynamic torsion. Steelwar eliminates structural vulnerabilities by designing multi-chamber interior extrusion profiles with internal reinforcement webs. For high-security installations, steel reinforcement bars or ballistic composite cores are inserted directly into the primary extrusion chamber. This hybrid construction seamlessly combines the corrosion resistance and architectural flexibility of aluminum on the exterior with the puncture resistance and structural rigidity of hardened steel on the interior.

Why leading global brands and commercial developers choose Steelwar as their strategic OEM manufacturing hub.
Situated within China's primary hardware and aluminum processing hub, Steelwar leverages an uninterrupted supply chain. Access to primary aluminum ingot smelters, specialized extrusion tooling die-makers, and advanced anodizing plants guarantees short procurement leads and minimal material transportation overhead.
Our automated surface treatment facilities execute PVDF liquid coating, electrostatic powder coating, and wood-grain thermal transfer technology. These coatings pass 3,000-hour salt spray testing (ASTM B117 standards), ensuring long-term protection against marine corrosion, UV fading, and surface scratching.
With an in-house tooling division managed by 75 R&D engineers, we take custom profile designs from CAD drawings to 3D physical extruded samples in under 14 working days. This rapid iterative process enables commercial clients to capture market trends quickly and fulfill custom architect specifications.
Aligning structural door frame manufacturing with strict building codes, energy conservation mandates, and smart access integration.
Modern building envelope design demands dual compliance: extreme weather impact resilience and rigorous thermal efficiency. Steelwar's reinforced door frames are engineered to meet North American and European regulatory frameworks:
The security entry market has transitioned from traditional mechanical mortise locks to integrated electronic access control. Steelwar leads this shift by customizing profile internal channels for seamless smart hardware mounting:
Whether you require custom extrusion dies for architectural restoration projects or bulk production of high-security frames for commercial hotel chains, Steelwar provides complete technical support: 2D/3D CAD shop drawings, finite element stress analysis (FEA), customized master batch colors, and tailored export packaging (isothermal timber crates).
Engineered to perform in demanding climate conditions and high-traffic commercial environments.
Designed specifically for Florida, the Caribbean, and coastal Southeast Asia. Features high-tensile 6061-T6 alloy frames with heavy-duty structural corner keys, stainless steel anchoring brackets, and dynamic water-drainage sub-sills that prevent water ingress during severe storms.
Reinforced thermal-break door frames engineered for multi-story office towers and commercial entries. Tested for continuous high-cycle operations, offering structural stiffness to handle high wind suction pressures at extreme elevation heights.
Specialized heavy-gauge frames integrated with anti-ballistic core inserts, concealed hydraulic closers, and face-recognition smart locking. Ideal for luxury residential panic rooms, diplomatic embassies, and financial vaults.
Direct technical answers addressing B2B procurement specs, manufacturing tolerances, and compliance standards.
Standard aluminum door frames typically utilize thinner extrusions (1.2mm - 1.4mm) with hollow single-chamber profiles designed for basic light-duty residential applications. Reinforced aluminum door frames utilize structural-grade T6 aluminum alloys (6063-T6 or 6061-T6) with wall thicknesses ranging from 2.0mm to 3.5mm, multi-cavity internal webbing, and optional steel or ballistic core inserts. Reinforced frames withstand significantly higher wind loads (Miami-Dade impact rating), offer greater forced-entry resistance, and prevent frame twisting when supporting heavy double-glazed or bulletproof glass panels.
Thermal breaks utilize a low-thermal-conductive material—typically PA66GF25 (Polyamide 66 reinforced with 25% glass fiber)—to mechanically join interior and exterior aluminum profiles. Because raw aluminum is a natural conductor of heat and cold, the polyamide thermal barrier interrupts thermal transfer, drastically reducing U-factors, preventing condensation on indoor surfaces, and significantly lowering building heating and cooling costs in compliance with NFRC and Energy Star standards.
For coastal, highly saline, or industrial polluted environments, Steelwar recommends a 3-coat Fluoropolymer (PVDF / Kynar 500) paint coating or Class I Hardcoat Anodizing (minimum 25-micron coating thickness). PVDF finishes provide exceptional resistance to salt spray, chalking, chemical exposure, and UV radiation, easily passing ASTM B117 salt spray testing for up to 3,000 hours.
Yes. Steelwar specializes in full OEM/ODM manufacturing. Our team of 75 R&D engineers creates custom extrusion dies, calculates structural load limits, and develops 2D/3D CAD models matching your architectural specifications. Custom die tooling is generally completed within 10 to 14 days, followed immediately by sample extrusion and physical testing.
For standard profile extrusions and stocked finishes, our baseline MOQ starts at 50 sets. For fully customized architectural extrusion dies, the MOQ depends on total aluminum weight (typically 1 to 3 metric tons). Production lead times average 25 to 35 days from sample confirmation, depending on order size and complexity of custom finish requirements.
