Exterior Door Manufacturer | EUWOO
Factory-direct exterior doors — steel construction, commercial-grade hardware, built for distributors and project contractors worldwide.
Three product lines covering standard exterior doors, front entry doors, and specialty configurations. Every unit manufactured in our own 18,000 m² facility in Luoyang, China — no trading company layer between your spec and the production floor.
What We Manufacture and Why It Matters to Your Supply Chain
EUWOO is the export brand of Luoyang Huahui Door Industry Co., Ltd. We've been manufacturing steel doors in Luoyang Industrial Park, Henan, since 2008 — and exterior doors have been part of that production from day one. When a buyer searches for an exterior door manufacturer, they're usually looking for one of two things: a factory that can supply a reliable catalog product at a competitive landed cost, or a manufacturing partner that can build to their spec for a private-label program. We do both, from the same floor, with the same quality system.
The distinction between a factory and a trading company matters here more than in most door categories. Exterior doors take abuse — weather, forced-entry attempts, high-cycle use in commercial buildings. The material choices, weld quality, coating process, and hardware integration all affect how the door performs in the field and how many warranty claims come back to you. When you source direct from the manufacturer, you can verify those decisions. When you source through a trader, you're trusting their word on specs they didn't set.

Body panel gauges from 1.0mm for standard residential-grade applications up to 1.5mm for commercial and high-security configurations. Frames are roll-formed from the same steel stock, with a frame-to-leaf fit tolerance held within ±0.5mm.
Zinc Phosphate Pre-Treatment
Every door goes through zinc phosphate pre-treatment before powder coating — the step that determines long-term corrosion resistance, not the powder itself. The automated coating line applies 60–80μm film thickness consistently, passing a 500-hour salt spray test.
Verified Certifications
The 500-hour salt spray threshold is the standard most North American and European buyers need for coastal and high-humidity markets.
Exterior Door Product Line
The exterior door category at EUWOO covers three product lines. Each has a distinct commercial application and buyer profile — the cards below give you the orientation; the product pages carry the full specs.
Exterior Door
Our core exterior door line — steel construction, available in single and double-leaf configurations, with a range of panel profiles from flush to embossed. Standard sizes cover the most common residential and light commercial rough openings, with custom sizing available from 100 units. Hardware packages include multi-point locking systems, heavy-duty hinges rated for 200,000+ cycles, and weatherstrip seals tested for air infiltration compliance.
This is the volume product in the category — the one that moves in container quantities for distributors stocking residential and light commercial projects.
View Exterior Door
Front Door
Built for applications where the entry point is also a visual statement — residential developments, boutique commercial buildings, hospitality projects. Steel construction with decorative panel options: raised moulding profiles, glass lite inserts (tempered or laminated), and a wider color palette drawing from our 60+ powder coat options. We also run wrought iron overlay panels for buyers targeting the premium residential segment.
A front door with a decorative profile and glass insert commands a meaningfully higher retail price than a flush steel door at similar manufacturing cost — your markup on this line is wider than on commodity exterior doors. This segment has grown steadily in North American and Gulf markets over the past three years.
View Front Door
Exterior Specialty Door
Covers configurations that don't fit the standard catalog: oversized openings, blast-resistant specs, bullet-resistant glazing, multi-point high-security locking, and custom architectural profiles for project-specific requirements. These are typically ODM orders — the buyer brings a spec or a performance requirement, our engineering team designs to it, and we produce to the approved drawing.
Lead times on specialty doors are longer and MOQ is 100 units minimum, but the margin profile is different from catalog product. If you're supplying government, embassy, data center, or critical infrastructure projects, this is the line to discuss.

Steel Gauge, Core Fill & Hardware:
How We Configure for Your Market
The most common sourcing mistake we see on exterior doors is under-specifying the body gauge for the end application. A 0.8mm panel is fine for interior use; on an exterior door taking direct weather exposure and daily use, it dents, it telegraphs frame distortion, and it generates warranty claims. Here's how we think about configuration by application.
| Application | Body Gauge | Core Fill | Hardware Package |
|---|---|---|---|
|
Standard residential (developer projects) |
1.0mm SPCC | Honeycomb paper or polyurethane foam | Single-point lock, 3× heavy-duty hinges |
|
Light commercial (retail, office entry) |
1.0–1.2mm SPCC | Polyurethane foam (thermal break) | Multi-point lock, 4× hinges, door closer |
|
High-traffic commercial (hotels, schools) |
1.2mm SPCC | Polyurethane foam | Multi-point lock, 4× hinges, closer, kick plate |
| High-security / project spec | 1.5mm SPCC | Steel stiffener ribs + foam | Multi-point deadbolt, 4× security hinges, anti-drill plate |
Core Fill Decision
Polyurethane foam gives you thermal insulation — relevant for North American energy code compliance and for buyers whose customers pay heating/cooling bills — and adds panel rigidity that reduces the hollow-knock sound end users associate with cheap doors. Honeycomb paper is lighter and lower cost: fine for markets where thermal performance isn't a selling point, but it won't pass energy code in most US states.
Hardware Pre-Installation
Hardware integration is done in-house at our assembly stations before the door ships. We don't send you a door and a bag of hardware — the lock cylinder is fitted, the hinges are hung, and the door is test-cycled before it goes into the carton. That pre-installation step is what eliminates the field assembly errors that generate after-sales calls.
Tell us your target market and we'll spec accordingly — core fill, gauge, and hardware package configured for your end application before the order is placed.
Where These Doors Go: Market Segments Worth Building Into Your Line
Exterior doors move across a wide range of project types. The segments below are the ones where our buyers are consistently placing repeat orders — which tells you something about where the commercial volume actually is.
Residential Development
Property developers in North America, the Gulf, and Southeast Asia buy exterior doors in project quantities — 200 to 2,000 units per development, on annual or semi-annual procurement cycles. If you're supplying building materials distributors or construction procurement companies, this is the segment driving their reorder cadence.
Hospitality & Commercial Construction
Hotels, serviced apartments, and mixed-use developments specify exterior doors by performance standard rather than catalog number. They need documented specs: air infiltration ratings, cycle-test data, finish durability. Our CE certification and SGS test reports cover the documentation requirements for most markets, and we can provide project-specific test data on request.
Government & Institutional Projects
Schools, municipal buildings, embassies, and correctional facilities often require enhanced security specs and third-party certification. NFPA 80 compliance covers the fire-rated exterior door requirements common in US institutional projects. For security-rated specs, our 1.5mm heavy-gauge line with multi-point locking and anti-drill hardware covers most institutional security requirements short of blast or ballistic ratings.
Replacement & Renovation
Renovation projects need doors that fit existing rough openings — which means custom sizing is a real commercial requirement, not an edge case. Our custom sizing capability from 100 units makes us a viable source for distributors serving the renovation trade, where standard catalog sizes often don't fit. This segment is consistently underweighted in distributor SKU planning.
Buyers supplying this segment
Our certification package — CE, SGS test reports, NFPA 80 — lets you pre-qualify for hospitality and institutional tenders without additional testing cost. Tell us your target segment and we'll confirm which documentation applies.
Coating, Corrosion Resistance & the Failure Mode That Costs You the Most
The most common exterior door failure in the field isn't structural — it's finish. Bubbling powder coat, rust bleed at weld seams, fading color on sun-exposed facades. These failures generate warranty claims, damage your reputation with downstream customers, and are almost always traceable to a pre-treatment shortcut at the factory.
Steel Surface Prep
Zinc Phosphate Pre-TreatmentAfter forming and welding, every door body goes through a zinc phosphate pre-treatment bath. Zinc phosphate creates a conversion coating on the steel surface that gives the powder coat a chemically bonded substrate, not just a mechanical adhesion.
We switched from iron phosphate to zinc phosphate in 2020 after seeing adhesion failures on orders going to coastal markets. The difference in salt spray performance is significant:
Powder Application
Electrostatic Automated LineElectrostatic application on an automated line, 60–80μm film thickness. The electrostatic charge wraps the powder around edges and into recessed panel profiles — the areas where manual spray application leaves thin spots that fail first.
Film thickness is checked with a digital gauge on every batch. Doors outside the 60–80μm window go back to the line.
Cure Oven
180–200°C Convection CureConvection cure at 180–200°C for full cross-linking of the powder chemistry. Under-cured powder looks fine on inspection but fails adhesion testing and chalks prematurely in UV exposure.
We run oven temperature logs on every production batch. If you need that documentation for your own QC file, we can provide it.
Our exterior doors pass a 500-hour salt spray test — the threshold for coastal installation in North American and European markets. Zero RMA for finish failures on properly installed doors.
Why Pre-Treatment Shortcuts Fail
- Bubbling powder coat at weld seams — mechanical adhesion without conversion coating fails under thermal cycling
- Rust bleed at edges — thin film coverage on profiles from manual spray application
- Premature UV chalking — under-cured powder that passes visual inspection but fails cross-link density
Packaging, Container Loading & Landed Cost
Exterior doors are a volume product, and container utilization directly affects your landed cost per unit. We've been loading containers for export since the early years of the business, and the KD flat-pack format we use is optimized for maximum loading density without sacrificing protection.
Standard KD Flat-Pack
Door leaf, frame sections, and hardware packed separately in reinforced double-wall cartons with foam corner protection. The frame ships in sections that reassemble on-site — this is the format that maximizes container loading and minimizes freight cost per unit.
Container Loading Quantities
Approximate — varies by door size and configuration
| Container |
Standard Exterior 900×2100mm |
Front Door with Glass Lite |
Heavy-Gauge Security Config |
|---|---|---|---|
| 20GP | 80–100 sets KD | 60–80 sets | 60–75 sets |
| 40HQ Best Value | 200–260 sets KD | 160–200 sets | 150–190 sets |
Working Backward From Your Margin
These numbers are what your freight team needs to calculate landed cost per unit before you commit to an order. If your target retail price or project budget requires a specific landed cost ceiling, send us that number — we'll work backward from it to identify the configuration and container mix that hits your margin.
Batch Traceability
Every carton carries a barcode linked to our production batch record.
If a quality question comes up on arrival, you can trace any unit back to its production date, line, and inspection record within minutes — which matters when you're dealing with a customs hold or a project site complaint.
Landed Cost Inputs Checklist
- Container type and loading quantity for your door configuration
- FOB unit price × quantity = FOB cargo value
- Ocean freight rate to your destination port
- Import duty rate for HS code applicable to your market
- Destination port handling and inland delivery

Customization Scope: OEM Private Label and ODM Project Development
Standard catalog orders are straightforward. The more interesting conversation for most buyers is what we can build to their spec.
OEM Private Label
Your brand, our manufacturing. We apply your logo, your color spec, your hardware brand, and your packaging design. The door is built to our standard construction spec (or a modified spec you approve) and ships under your label.
- MOQ 50 units for standard configurations
- MOQ 100 units for custom colors or hardware packages
- 15-engineer R&D team handles design documentation and production sign-off
- 3D renderings for approval before we cut steel
ODM Custom Development
You bring a performance requirement or a design reference, we engineer the solution. This is the path for buyers who need a door that doesn't exist in any catalog.
- Specific security rating or unusual size requirements
- Decorative profiles for branded developments
- Configurations combining features from multiple product lines
- 15–20 working days from spec submission to first sample
Color & Finish Customization
60+ standard powder coat colorsRAL color matching available for custom specifications. Minimum run for a custom color is 100 units — below that, the powder line changeover cost doesn't make sense for either side.

Sourcing Exterior Doors: What to Verify Before You Commit
Most quality problems on exterior door orders are predictable — they come from the same shortcuts that factories take when margin pressure is high. Here's what to check.
Body Gauge vs. Stated Spec
Material Certificate RequiredRequest a material certificate from the steel mill for the coil used in your production batch. The certificate shows actual gauge and steel grade.
Common substitution to watch for: A door quoted at 1.2mm that's actually running 1.0mm coil. The weight difference is detectable on arrival if you know what to look for.
Pre-Treatment Process
Ask SpecificallyAsk specifically whether the factory runs iron phosphate or zinc phosphate pre-treatment.
Iron Phosphate
Cheaper and faster. Not suitable for exterior applications in humid or coastal markets.
Zinc Phosphate
Required for exterior applications in humid or coastal markets.
If the factory can't tell you which process they run, that's your answer.
Hardware Cycle Rating
Request the Test ReportHinges and lock mechanisms on exterior doors should be rated for 200,000+ cycles minimum for commercial applications.
Warranty Risk
Hardware that fails at 50,000 cycles generates warranty claims within the first year of installation. Always ask for the test report.
100% vs. Statistical Inspection
Know the DifferenceSome factories inspect a sample of outgoing product. The difference shows up in your defect rate on arrival.
Statistical Sampling
Passes a predictable percentage of defects through to your container.

Frequently Asked Questions
Spec decisions, compliance requirements, MOQ thresholds, and finish durability — answered directly from our engineering and sales teams.
What steel gauge should I specify for commercial exterior doors?
For standard commercial applications — office buildings, retail, light industrial — 1.0–1.2mm SPCC cold-rolled steel is the right range. The 1.0mm spec covers most light commercial requirements and keeps weight and freight cost manageable.
Step up to 1.2mm for high-traffic applications (hotels, schools, government buildings) where door abuse is higher and dent resistance matters.
For security-rated applications or correctional/institutional projects, specify 1.5mm with steel stiffener ribs in the core — the added weight is significant (roughly 15–20% more per unit) but the structural performance difference is real.
What certifications do I need for exterior doors going into the US market?
For standard commercial exterior doors in the US, the primary compliance requirement is energy code — doors in conditioned spaces need to meet IECC U-factor and air infiltration requirements, which vary by climate zone. Our polyurethane foam-core doors with weatherstrip seals meet the thermal performance thresholds for most US climate zones.
For fire-rated exterior doors specifically (stairwell exits, rated corridor openings), NFPA 80 compliance is required — we hold that certification. CE covers European market requirements.
If your project has a specific code requirement you're not sure about, send us the spec and we'll confirm whether our standard product covers it or whether a modified configuration is needed.
What is the minimum order quantity for exterior doors?
50 units for standard catalog configurations. 100 units for custom colors, non-standard sizes, or custom hardware packages.
For ODM specialty configurations, MOQ is quoted individually based on tooling requirements — most specialty projects start at 100 units minimum.
How do I prevent exterior door finish from failing in coastal or high-humidity environments?
The failure point is almost always pre-treatment, not the powder coat itself. Specify zinc phosphate pre-treatment (not iron phosphate) and a minimum 60μm powder coat film thickness.
Ask for a salt spray test report — the threshold for coastal applications is 500 hours minimum. Our standard exterior door production meets this spec; if you're sourcing elsewhere, request the test report before you commit to a large order.
What is the lead time for exterior door orders?
We've shipped to Los Angeles, Houston, Dubai, Singapore, Lagos, and Sydney — the documentation package for customs clearance is complete and standard for all active markets.
