Metal Door Factory-Direct
Broad-spec metal doors built for buyers who source across multiple project types — one supplier, one QC standard, full configuration flexibility.
EUWOO manufactures metal doors in steel, galvanized, and stainless steel construction from our 18,000 m² facility in Luoyang, China. 450,000-unit annual capacity, ISO 9001:2015 and CE certified, with OEM/ODM programs from 50 units.
What "Metal Door" Means in a Sourcing Context — and Why the Flexibility Matters
The term "metal door" is deliberately broad, and that's the point. When you're building a product line for a distributor catalog, stocking for a contractor network that works across project types, or sourcing for a mixed-use development where the spec changes floor by floor, you need a door that doesn't lock you into a single construction standard or material grade. That's the commercial logic behind this product.
Our metal door line covers the full material spectrum — cold-rolled SPCC steel, hot-dip galvanized steel, and 304/316 stainless steel — in a single consistent manufacturing program. Same factory, same 5-stage QC process, same hardware prep standards, same powder coating line. What changes is the substrate and the configuration. That consistency matters when you're managing a multi-SKU order or consolidating suppliers: your quality baseline doesn't shift between line items.
Where this product sits in our commercial door range: it's the flexible-spec option. If your project requires a specific construction standard — ANSI/SDI hollow metal, or a fire-rated assembly — our hollow metal commercial doors or fire door lines are the right call. If you need a door that can be configured across steel types, finishes, and hardware preps without committing to a single standard, this is the product.
Most of our buyers in this category are distributors building multi-market catalogs and contractors sourcing for mixed-spec projects.

Request Exact SpecsMaterial Selection: Steel, Galvanized, or Stainless — How We Think About It
This is the decision that drives most of the cost and performance difference in a metal door order, and it's worth getting right before you quote your downstream customers.
Cold-Rolled SPCC Steel
The standard choice for interior commercial applications and most exterior applications in moderate climates. The bulk of our production runs on SPCC — 1.0mm body gauge for standard commercial use, 1.2mm for higher-traffic environments.
Gauge Range
1.0mm – 1.2mm body
Hot-Dip Galvanized Steel
The choice when the door is going into a genuinely corrosive environment. The galvanized substrate gives you a sacrificial zinc layer that protects the steel even if the surface coating is scratched or damaged.
Gauge Range
0.7mm – 1.2mm (+ zinc coating)
304 / 316 Stainless Steel
Specified when hygiene, aesthetics, or extreme corrosion resistance is the primary driver. 304 stainless at 1.0–1.2mm can be cleaned with industrial sanitizers without surface degradation. 316 is available for marine or chemical exposure where 304's chloride resistance isn't sufficient.
Gauge Range
1.0mm – 1.2mm (304 or 316)
The Practical Selection Guide
Buyer asks:
"What's the most cost-effective metal door for this project?"
→ Start with SPCC and the right gauge.
Buyer asks:
"What won't corrode in this environment?"
→ Galvanized or stainless depending on severity.
Buyer asks:
"What meets the hygiene spec?"
→ Stainless.
Where Metal Commercial Doors Sell: Market Segments and Order Patterns
Understanding which segments drive volume — and how they reorder — helps you position inventory and build the right supplier relationship from the start.
Commercial Construction & Fit-Out
The core volume segment. Office towers, mixed-use developments, retail fit-outs, and hotel projects specify metal doors across interior and exterior applications. The spec flexibility of this product — multiple steel types, multiple gauges, multiple finishes — means you can cover the full project spec from a single order rather than splitting across multiple product lines.
Typical Order Size
50–200 door sets
mid-size fit-out
Large Development
500+ door sets
generates follow-on volume
Institutional Construction
Schools, hospitals, government buildings — buys metal commercial doors in predictable volume on defined procurement cycles. These buyers specify to standards and buy on approved vendor lists, so the compliance pre-qualification work is front-loaded. Once you're on the list, the reorder pattern is reliable. Our ISO 9001:2015 and CE certifications are the entry tickets for most institutional procurement processes outside North America.
School District Reno
200–500 doors
per project
Hospital Wing
300–800 doors
NFPA 80 docs available
Food Service & Hospitality
A growing segment for stainless steel specifically. Commercial kitchens, hotel back-of-house, food processing facilities, and restaurant chains all specify stainless for hygiene compliance. The spec is locked once you've supplied the first batch — chains reorder as they expand.
Growing consistently in Southeast Asia and the Middle East over the past three years — worth building into your catalog if you're serving those markets.
Industrial & Manufacturing
High-abuse environments where the door takes regular impact from equipment, carts, and foot traffic. 1.5mm gauge with reinforced frame corners is the standard spec here. These buyers replace doors on a rolling basis as units wear out — the reorder cycle is ongoing rather than project-based.
If you're supplying into industrial distribution, this is a reliable repeat-order segment.
Export & Multi-Market Distribution
The broad-spec nature of this product makes it particularly useful for distributors who supply into multiple markets with different construction standards. One SKU range, configured to local hardware prep standards, covers North American, European, and Gulf market requirements without maintaining separate product lines.
Manage one supplier relationship while your downstream customers get a locally-compliant product.
Order Pattern Summary
Commercial Fit-Out
Project-based with follow-on volume as projects progress
Institutional
Defined procurement cycles — front-loaded qualification, reliable reorder
Food Service Chains
Spec locked on first supply — reorders as chain expands
Industrial
Ongoing rolling replacement — not project-dependent

Powder Coat and Surface Finish: What Protects Your Margin Downstream
Surface finish is where most metal door warranty claims originate. Understanding what separates a finish that holds from one that doesn't is the difference between a profitable product line and a costly returns problem.
Coating Line Specifications
Zinc Phosphate Pre-Treatment
The step most buyers don't ask about — but should
Our pre-treatment sequence runs a zinc phosphate conversion coating on every door before it enters the coating line. Zinc phosphate creates a crystalline conversion layer on the steel surface that gives the powder coat a mechanical and chemical bond — it's what determines whether the coating holds at weld seams and edges, which is where failures almost always start.
Weld Seam Treatment
Secondary phosphate on every seam before main pre-treatment
Every weld seam gets ground flush and receives a secondary phosphate treatment before the door enters the main pre-treatment line. This adds process time, but it's the difference between a 500-hour salt spray pass and a field failure at 18 months.
Coastal Market Upgrade: 1000-Hour Salt Spray
For coastal markets — Gulf, Southeast Asia, Australia — we offer a 1000-hour salt spray spec on request. This adds a zinc-rich primer undercoat before the topcoat powder. The cost delta is modest; the warranty claim prevention is significant.
Available on requestColor Consistency for Chain Supply
ΔE < 1.5 across a full production run. If you're supplying a chain or a large project where color consistency across hundreds of doors matters to your customer, that tolerance is what keeps the relationship.
Custom RAL & Brand Colors
Available on runs of 100+ units with a color match sample before the production run commits. No surprises on delivery — you approve the match first.
Stainless Steel Finishes
Brushed (No. 4) and mirror (No. 8) as standard. Brushed is the practical choice for most commercial applications — hides minor surface marks and easier to maintain. Mirror finish for high-visibility architectural applications.
Film thickness note: 60–80μm is held across the full panel surface — consistent across the batch, not just on flat faces. This matters at edges and corners, where thinner coverage is the typical failure point on lower-spec coating lines.
Frame Construction and Hardware Prep: What Determines Field Performance
The door leaf gets specified and compared. The frame is what determines whether the installation performs for the life of the building — and it's where most field failures actually originate.
Frame Construction Standards
1.5mm minimum gauge
Heavier than the door leaf on most configurations. Frame gauge is where long-term dimensional stability is set.
Welded gusset corners
Corners are welded with gusset reinforcement rather than mechanical fasteners. The weld holds dimensional stability under the cyclic loading of daily use in a way that screwed corners don't.
±0.5mm frame-to-leaf fit tolerance
Held on our production line. Matters when you're fitting doors in the field and can't afford rework on a large project. We tightened that tolerance after early export orders came back with frame-fit complaints — the fix was straightforward but the lesson stuck.
Hinge Configuration
3-hinge standard on single-leaf doors up to 1200mm wide and 2400mm tall
4-hinge configuration available for heavy-gauge doors, oversized leaves, or high-cycle applications
Continuous hinge prep available for warehouse and industrial applications where cycle count is a concern — on any door in the line
Hardware Prep: International Standards
Hardware prep covers the full range of international standards. For project orders where hardware is being supplied separately, send us the hardware schedule and we'll confirm compatibility before production.
Mortise and cylindrical lock prep to ANSI A115 series; hinge prep to ANSI A156.7; closer reinforcement to ANSI A156.4
Lock prep to EN 12209; hinge prep to EN 1935; panic hardware prep to EN 179/EN 1125
Australian and New Zealand hardware standards available on request
Pre-Hung Complete Assemblies
We can supply doors pre-hung with hardware if your downstream customers need a complete assembly. Reduces installation complexity and eliminates hardware compatibility issues on site.
Hardware Schedule Compatibility
For project orders where hardware is being supplied separately, we'll prep to your hardware schedule. Send us the hardware spec and we'll confirm compatibility before production commits.
OEM/ODM: Private-Label Metal Doors for Your Brand
Most of our distributor partners in North America, Australia, and the Gulf run our metal doors under their own brand. The OEM program covers the full scope: custom dimensions, custom colors, custom hardware prep, private-label packaging, and brand plates on the door.
Dimensional Customization
Non-standard opening sizes handled on our press brake and roll-forming lines — oversized widths for accessible entrances, reduced heights for mezzanine applications, unusual aspect ratios for architectural projects. Runs of 100+ units require no dedicated tooling. Below 100 units, we discuss tooling economics upfront.

Frequently Asked Questions
What is the difference between a metal door and a steel door — are they the same product?
In manufacturing terms, steel doors are a subset of metal doors. "Metal door" covers steel (cold-rolled SPCC, galvanized, stainless), aluminum, and other metal substrates. In practice, when buyers search for "metal door" they're usually looking for a steel-bodied door with flexibility across material grades and configurations — which is exactly what this product covers. If your spec calls specifically for aluminum construction, our aluminum commercial doors are the right product. If your spec calls for a specific construction standard like ANSI/SDI hollow metal, see our hollow metal commercial doors.
What gauge steel should I specify for a metal commercial door in a high-traffic environment?
For standard office and light commercial interiors, 0.8–1.0mm SPCC is the right call — cost-competitive and adequate for the abuse profile. For high-traffic institutional environments (hospital corridors, school hallways, government buildings), specify 1.2mm minimum body gauge with a 1.5mm frame. For industrial and abuse-prone environments (loading docks, manufacturing plants, correctional facilities), move to 1.5mm body with reinforced frame corners.
Spec note: The gauge jump from 1.0mm to 1.2mm adds roughly 8–12% to unit cost but eliminates the denting and panel deformation complaints that generate warranty claims in high-traffic applications.
What certifications do metal commercial doors need for export markets?
For North American projects: NFPA 80 compliance for fire-rated assemblies; ANSI/SDI A250.8 for hollow metal construction standard. For European and Gulf markets: CE marking covers structural and fire-rated products. Our ISO 9001:2015, CE, SGS, and NFPA 80 certifications cover the compliance requirements for our primary export markets.
SGS audit reports are available on request for buyers who need third-party documentation for their own import compliance files.
Can metal doors be supplied with stainless steel finish for food service applications?
Yes. We supply 304 stainless steel metal doors as a standard configuration — brushed (No. 4) or mirror (No. 8) finish. For food processing and pharmaceutical applications where chemical resistance is a requirement, 316 stainless is available on request. Stainless doors can be supplied with all standard hardware preps and frame configurations.
MOQ for stainless configurations: 50 units for standard sizes.
What is the MOQ and lead time for custom metal doors?

Depending on current line loading
We produce a pre-production sample for your approval before committing the full run — sample lead time is 15–20 working days from spec confirmation.
How do I prevent powder coat failure on metal doors in coastal or humid climates?
The failure almost always starts at weld seams, not on flat panel surfaces. The fix is in the pre-treatment: weld seams need to be ground flush and treated separately before the standard phosphate wash, because the heat-affected zone from welding changes the surface chemistry and reduces adhesion.
For coastal markets: Specify a zinc-rich primer undercoat before the topcoat powder — this adds a sacrificial corrosion barrier that extends coating life significantly in salt-air environments.
Ask your supplier specifically about their weld pre-treatment process. If they can't describe it in detail, the coating process probably isn't adequate for your market.
