Steel Security Door Direct From Factory
The core SKU in our security door range — cold-rolled SPCC body, multi-point locking, 60+ finish options, built for volume distribution and project supply.
EUWOO's steel security door is the highest-volume product off our Henan production floor. Consistent dimensional tolerances across large runs, 500-hour salt spray finish, and pre-installed hardware to your market's lock standard — the spec that moves in residential, commercial, and mixed-use projects across five continents.
What This Door Is and Where It Sits in the Range
The steel security door is the foundational SKU in our security door lineup — the product that accounts for the largest share of our export volume and the one most distribution catalogs are built around. Cold-rolled SPCC body, powder-coated finish, multi-point locking, reinforced frame: the configuration that covers the widest range of residential and commercial applications without over-speccing for standard use.
We run this product on dedicated lines. The tooling is mature, the process is dialed in, and the dimensional consistency across a 500-unit run is the same as across a 50-unit run. That matters when you're supplying a developer who needs every door in a 300-unit apartment block to fit the same rough opening without field adjustment.
Where It Sits in the Range
Mid-spec, broad-market volume workhorse. Covers the majority of residential and light commercial inquiries without requiring a custom quote. The SKU you stock in depth.
Heavier gauge, anti-pry edge profiles, and institutional-grade hardware. For projects that need to exceed standard residential spec.
Access control prep, vision panels, and architectural finishes for office and retail projects. When the spec calls for more than standard residential.

Request Specification SheetThe Lock Zone and Hinge Engineering: Where Most Doors Fail
The body gauge gets quoted in every spec sheet. The lock zone and hinge construction are where the real performance difference lives — and where most security door failures originate in the field.
Full-Height Lock Zone Reinforcement
The lock zone runs a full-height internal reinforcement channel — 2.0mm cold-rolled steel welded to the inner face of the door body at the lock rail. The channel distributes kick-force across the full height of the door rather than concentrating it at the bolt point.
Why it matters: A door body that deflects at the lock zone under impact is a security failure regardless of what the body gauge says. We've seen 1.5mm doors from other suppliers fail at the lock zone because the reinforcement was a short plate rather than a full-height channel — the body held but the bolt pulled through.
Hinge Plate Specification
Hinge plates are 3mm on standard configurations, 4mm on the 1.5mm gauge version, welded full-perimeter to the door body. Full-perimeter weld means the plate can't peel under lateral load — a common failure mode when hinge plates are tack-welded at corners only.
QC checkpoint: Every door is cycled through open/close testing at final inspection. We catch hinge binding and misalignment before the door packs, not after it arrives at your warehouse.
Multi-Point Locking: Standard Configuration
3-point base configuration — 5-point and 7-point available on request.
Factory hardware pre-installation to your specified lock standard: ANSI Grade 1 or Grade 2 (North America), EN 12209 (Europe and Gulf markets).
Why factory installation: Field hardware installation is where most security door failures originate — misaligned strike plates, undertorqued hinge screws, incorrect backset. Pre-installation at the factory eliminates that variable entirely.
Why We Started Offering Factory Hardware Installation
We started offering factory hardware installation after seeing a pattern of lock complaints on early export orders that turned out to be installation errors, not product defects. The fix was to take installation out of the equation.
Surface Finish: The 500-Hour Salt Spray Standard and What It Means for Your Accounts
The finish on a steel security door is a warranty liability issue, not an aesthetic one. Powder coat that fails in the field — bubbling at weld seams, peeling at edges, rust bleed-through in humid environments — generates warranty claims and replacement orders that erode your margin on the original sale.
Zinc Phosphate Pre-Treatment
Every door body goes through a full-immersion zinc phosphate bath after welding and before powder coating. We switched from iron phosphate to zinc phosphate in 2020 after seeing adhesion failures on orders going to coastal markets in Southeast Asia.
Weld Seam Grinding & Re-Treatment
Before the door enters the phosphate bath, every weld seam is ground and re-treated. This is the step most manufacturers skip because it adds labor time.
Failure mode prevented: Powder coat adhesion failure at weld lines, typically appearing 6–18 months after installation in humid environments — the most common finish defect on competitor product returns.
Electrostatic Powder Coat Application
Applied electrostatically at 60–80μm film thickness across the full panel surface, including recessed panel profiles. Convection cure oven bonds the coating uniformly — no thin spots at edges or corners.

Color & Custom Finish Options
- 60+ standard RAL colors available off the line
- Custom color matching available on runs of 100 units or more, where powder line changeover cost makes sense for both sides
For Your Coastal and High-Humidity Accounts
The zinc phosphate gives better corrosion resistance at the substrate level, particularly at weld seams where scale and oxidation are hardest to remove. The difference shows up in salt spray testing: iron phosphate pre-treatment typically passes 300–350 hours; zinc phosphate gets us to 500 hours consistently. For your coastal and high-humidity accounts, this process difference is the reason you won't be fielding finish complaints.
Market Segments: Where This Door Generates Repeatable Volume
Four distinct buyer segments drive consistent reorder volume for this SKU. Understanding which segment fits your distribution model determines how you build inventory depth and forecast turns.
Residential Construction & Developer Supply
Residential developers sourcing for apartment blocks and housing projects typically standardize on one or two door SKUs per project — 200 to 1,000 units per phase, with repeat orders tied to construction phases. The steel security door at 1.2mm gauge is the spec that fits most residential building codes across our active markets and keeps freight cost reasonable.
Distributors who serve residential contractors can build a reliable reorder cycle around this SKU — the spec doesn't change project to project, so your inventory turns predictably.
Mixed-Use Commercial & Retail
Drives demand for the 1.2mm configuration with access control prep and architectural finishes. Order sizes run 50–200 units per project, with higher per-unit margin because the spec includes hardware packages and custom color.
This segment is growing in Southeast Asia and the Gulf as commercial construction activity increases — worth building catalog depth if you're in those markets.
Property Management & Renovation
Property managers replacing doors across a portfolio order in batches of 20–100 units, often on short lead times, and they reorder from the same supplier as long as the product fits and the service is reliable.
The steel security door's standard sizing (900×2000mm covers the majority of residential rough openings) means fit is rarely an issue. This segment has grown steadily for our Gulf and Southeast Asian distributors — worth a few SKUs in your catalog if you serve property management companies.
Export & Private-Label Distribution
Buyers building their own branded security door line use this product as the base SKU. The OEM program covers panel profile customization, hardware specification, and full private-label branding from 100 units.
The steel security door's broad market applicability makes it the right anchor product for a private-label line — you're not building a catalog around a niche spec.
Customization: What Can Be Specified, What Can't, and What It Does to MOQ
The steel security door is the most customizable product in our range because the tooling is mature and the production process is well-understood. Here's what's actually available — including where MOQ thresholds change.
Size Customization
Standard sizes cover 800×2000mm through 1000×2100mm. Custom widths from 750mm to 1200mm and custom heights from 1900mm to 2400mm are available.
Gauge Selection
1.0mm, 1.2mm, and 1.5mm body gauge are standard options with no MOQ premium. The 1.0mm option is available for price-sensitive residential markets; not recommended for commercial applications.
Panel Profile
Standard embossed panel profiles available off existing tooling at no additional cost. Custom panel profiles (different emboss patterns, decorative inserts, flush panel) require tooling, amortized across the order.
Hardware Configuration
Lock standard (ANSI Grade 1/2, EN 12209), lock point count (3/5/7-point), handle style, and cylinder type are all specifiable at standard MOQ. Supplied components or performance-spec sourcing both supported.
Color & Finish
60+ standard RAL colors at standard MOQ. Custom color matching (Pantone or RAL reference) available — powder line changeover and color approval process requires minimum run.
Access Control Prep
Conduit runs, junction boxes, and electric strike prep added at the factory. Send the hardware system spec and we configure the door prep accordingly — no field modification required.

Container Loading and Landed Cost Data
Concrete loading figures for your freight planning. Numbers vary by leaf thickness and format — here's what to expect before you commit to a container.
40HQ — Standard Leaf
220–260 sets
900×2000mm, 45mm leaf thickness, KD flat-pack format. Upper end of range assumes efficient carton stacking.
40HQ — Thick Leaf
180–220 sets
60–80mm leaf configurations. Heavier carton weight and increased leaf volume reduce per-container yield.
20GP — Trial Orders
90–110 sets
Standard single-leaf doors, KD format. The format most buyers use for trial orders and initial stocking runs.
KD Flat-Pack: Why It's the Default
KD flat-pack ships the door leaf, frame, and hardware separately in reinforced double-wall cartons with foam corner protection on the door leaf. Frame sections are bundled and wrapped; hardware is bagged and packed inside the door leaf carton.
This format eliminates the lock misalignment problem that affects pre-hung assemblies in transit. Doors that ship assembled can rack slightly under container load, shifting bolt alignment enough that the door won't latch cleanly on arrival. KD format removes that variable entirely.
Most buyers who have a choice opt for KD. It's the lower-risk format for long-haul freight.
Pre-Hung Assemblies: When You Need Them
For buyers who need pre-hung assemblies — some project specs require it — we ship in foam-lined crates with corner guards and cross-bracing.
| Container | Format | Sets / 40HQ |
|---|---|---|
| 40HQ | KD flat-pack | 220–260 |
| 40HQ | Pre-hung crated | 130–160 |
Container utilization drops to approximately 130–160 sets per 40HQ in pre-hung format. The crating volume is the cost.

Certifications and Compliance for Your Target Market
The steel security door ships with ISO 9001:2015, CE, and SGS certification. Here's what each means for your import and resale compliance.
Quality Management System
Covers documented process controls, incoming material inspection, in-process checks, and outgoing inspection. The baseline most commercial buyers require from overseas suppliers and the foundation for the 100% pre-shipment inspection standard run on every unit.
European Conformity
Covers European conformity for structural products — relevant for buyers supplying EU markets or markets that recognize CE as an import qualification standard. The Gulf and parts of Southeast Asia accept CE as a compliance reference even where it's not formally required.
Third-Party Audit & Testing
Independent verification of facility, process, and product that carries weight with buyers who need documentation beyond self-certification. SGS audit reports are available on request for your import compliance files.
North American Buyers
There is no single mandatory federal certification for standard security doors (unlike fire doors, which require NFPA 80 listing). Most commercial projects specify ANSI/BHMA hardware grades — we configure to ANSI Grade 1 or Grade 2 as specified.
Our ISO 9001:2015 and SGS certifications satisfy most import compliance requirements. If your project has a specific certification requirement, send us the spec and we'll confirm whether our product qualifies.
Material Compliance
Our powder coating uses zero-VOC chemistry, and steel sourcing is from approved domestic mills.
RoHS and REACH compliance documentation is available on request for buyers whose downstream customers or building projects have material safety requirements.

Buyer FAQs: Steel Security Door Sourcing
Decision-support answers for importers, distributors, and project buyers specifying steel security doors.
What body gauge should I specify for a steel security door going into residential versus commercial applications?
Residential (apartments, condominiums, private homes): 1.2mm SPCC is the market standard in most regions and the right balance of security performance and freight cost. The 1.0mm option exists and moves well in price-sensitive markets, but we don't recommend it for anything above ground-floor residential — the body deflects under sustained force in a way that 1.2mm doesn't.
Commercial (office buildings, retail, light industrial): 1.2mm with internal reinforcement channels at the lock zone is the spec we ship most.
Institutional and high-security: Step up to 1.5mm body gauge with multi-point locking and reinforced hinge plates. The freight cost difference between 1.2mm and 1.5mm on a 200-unit order is real but smaller than the cost of a single forced-entry incident for your end customer.
What is the difference between a steel security door and a stainless security door?
Standard steel security door: Uses cold-rolled SPCC carbon steel with a powder-coated finish for corrosion protection.
Stainless security door: Uses 304 or 316 stainless steel — inherently corrosion-resistant without a coating layer. Right spec for coastal environments with salt air exposure, food processing facilities, or applications where the door surface will be regularly washed down with chemicals.
For standard residential and commercial applications, SPCC with zinc phosphate pre-treatment and 60–80μm powder coat passes 500-hour salt spray and is the cost-effective choice. If your market is coastal or your application involves chemical exposure, ask us about the stainless configuration.
How do I verify that the lock and frame spec on a steel security door will actually resist forced entry?
Three things to check:
Lock zone reinforcement
Full-height internal channel, not a short plate.
Hinge plate attachment
Full-perimeter weld, not tack welds at corners.
Frame gauge
The frame should be at least as heavy as the door body — a 1.2mm door in a 1.0mm frame is a security failure waiting to happen.
Ask your supplier for cross-section drawings showing the lock zone construction and hinge plate detail. If they can't provide those drawings, the construction details are probably not worth examining.
What is the MOQ for a custom-size steel security door?
Standard Sizes
50 units
800×2000mm – 1000×2100mm
Custom Sizes
100 units
750–1200mm W, 1900–2400mm H
Outside those ranges, tooling changes are required and we quote individually. For custom panel profiles or non-standard hardware configurations, 100 units is the minimum where the setup cost makes sense for both sides.
Can steel security doors be pre-wired for access control systems?
Yes. We can add conduit runs, junction boxes, and electric strike or magnetic lock prep during factory assembly. The specific prep depends on the access control hardware your end customer is using — send us the hardware system model or spec sheet and we'll configure the door prep accordingly.
Factory pre-wiring is significantly cleaner than field modification and eliminates the risk of structural warranty issues from post-installation drilling.
How does KD flat-pack affect installation cost compared to pre-hung assemblies?
KD Flat-Pack
220–260 sets
per 40HQ container
Pre-Hung
130–160 sets
per 40HQ container
KD flat-pack ships the door leaf and frame separately, improving container utilization and eliminating transit racking that can shift lock bolt alignment. The trade-off is that installation requires frame setting and door hanging on site — typically 30–45 minutes per opening for an experienced installer.
Pre-hung assemblies reduce installation time but increase freight cost per unit due to lower container utilization and crating requirements. Most buyers who have a choice opt for KD; the freight savings across a 200-unit order typically outweigh the installation labor difference.
