Request Seattle Spec SheetEstablished in 2003, Steelwar Entry Systems Co., Ltd. operates a massive, state-of-the-art 40,000 m² manufacturing plant specialized in high-security exterior entry doors. Backed by 21 years of continuous industry experience and 9 years of global export capabilities, Steelwar generates over $35 million in annual export turnover. We serve key markets across North America, the Middle East, and Eastern Europe, positioning ourselves as the premier OEM/ODM manufacturing partner for building material distributors, security door stockists, and commercial construction contractors in the Greater Seattle area.
Supported by a robust trade background and an interconnected network of 1,100 supply chain partners, Steelwar guarantees unmatched material purity and structural precision. Factory quality control is rigorously driven by a dedicated team of 50 QC specialists executing dynamic impact resistance testing, automated frame tolerance checks, and corrosion-resistant coating audits. Our engineering capability is led by 75 R&D engineers who introduced 230 new product models last year alone. Bespoke manufacturing options include ballistic steel cores, multi-point smart lock integration, customized RAL color finishes, and bespoke frame depths engineered for Pacific Northwest structural demands.
Seattle's unique coastal marine environment (Cfb climate classification), combined with stringent Washington State Energy Codes (WSEC), demands entry door systems that transcend conventional manufacturing standards.
Seattle receives an average of 152 rainy days annually, accompanied by corrosive marine salt fogs from Puget Sound and Elliott Bay. Steelwar entry doors utilize A60 galvannealed steel substrates coated with multi-layer fluorocarbon (PVDF) electrostatic powder systems. This guarantees 3,000+ hours of ASTM B117 salt spray corrosion protection while preventing moisture ingress under DP65 wind loads.
The 2021/2024 Washington State Energy Code enforces strict U-factor performance metrics (≤ 0.24 Btu/h·ft²·°F) for vertical fenestration. Our thermal break technology incorporates high-density polyurethane (HD-PUR) cores and polyamide mechanical breaks, delivering thermal insulation performance that dramatically reduces HVAC energy loads in downtown Seattle high-rises.
Located in a active seismic zone governed by the Cascadia Subduction fault line, Seattle commercial projects require dynamic structural tolerance. Steelwar heavy-duty jambs and high-tensile steel frame anchors accommodate up to 2.5% inter-story drift without jam binding or structural glass frame cleavage during seismic shear displacement.

| Water Penetration Resistance | 5.25 PSF (ASTM E331) | 15.0 PSF Continuous Dynamic Load | ASTM E331 / AAMA 501.1 Wind-Driven Rain |
| Acoustic Isolation (STC Rating) | STC 28 - 32 | STC 45 - 52 Heavy Acoustic Core | Seattle Urban Noise Mitigation Code |
| Corrosion Resistance Rating | 500 Hours Salt Spray | 3,000+ Hours ASTM B117 Marine PVDF | Puget Sound Salt Fog Exposure Std |
| Forced Entry Security Rating | Grade 2 Standard Latch | Grade 1 Multi-Point + Ballistic Core | ANSI/BHMA A156.2 / UL 752 Level 3 |
Every high-security entry door deployed to the Seattle market undergoes an 11-stage automated manufacturing pipeline supervised by 50 certified QC specialists and 75 R&D engineers.
Computer-Aided Architectural Engineering & Custom Bespoke Frame CAD Integration
Our 50 QC specialists perform automated frame tolerance checks down to ±0.5mm precision, dynamic drop-weight impact resistance verification, and 100% audits of multi-layer corrosion-resistant coatings before ocean freight dispatch to the Port of Seattle or Port of Tacoma.
From tech campus headquarters in South Lake Union to heavy industrial facilities along the Duwamish Waterway, Steelwar delivers specialized architectural solutions.
High-density mixed-use developments demand high acoustic isolation (STC 45+) and seamless electronic access integration. Our custom flush steel and architectural glazed entry systems provide ultra-clean sightlines while maintaining thermal break barrier performance against high-altitude urban wind shear.
For single-family and luxury multi-family projects in Bellevue, Mercer Island, and Kirkland, Steelwar designs custom RAL finished entry assemblies featuring solid wood veneer cladding over ballistic steel cores, offering timeless craftsman aesthetics paired with modern defense capabilities.
Industrial facilities around SODO, Georgetown, and SeaTac demand ruggedized security entry points. We manufacture 3-hour UL 10C fire-rated steel doors equipped with heavy-duty panic hardware, anti-pry frame tabs, and impact-resistant internal core ribs.
Deploying AI-driven automated structural optimization, digital twin BIM models, and carbon-neutral manufacturing workflows for global enterprise procurement.
All Steelwar door assemblies now provide full LOD 350-400 BIM objects natively compatible with Autodesk Revit and digital twin facilities management software, streamlining specifying workflows for Seattle architectural firms.
