What Makes a Single Security Door the Right SKU
for Most Sourcing Programs
The single-leaf configuration is the workhorse of the security door market. One door, one frame, one opening — it covers the majority of residential entry applications, most commercial interior secure zones, and a wide range of light institutional uses. If you're building a distribution catalog, this is the SKU that moves in volume. If you're sourcing for a construction project, this is the configuration that fits 80% of your openings without custom engineering.
What separates a well-built single security door from a commodity product isn't visible in a product photo — it's in the steel gauge, the frame construction, the hinge attachment, and the pre-treatment under the powder coat. We've been manufacturing single-leaf security doors since 2008, and the spec decisions we've made over that time are driven by what actually fails in the field and what generates warranty claims for our buyers.
The door body runs 1.2mm cold-rolled SPCC as standard — enough to resist the deflection that causes lock misalignment under forced entry, without adding unnecessary freight weight. The frame runs 1.5mm gauge with a minimum of three anchor points per jamb, because a 1.2mm door in a flimsy frame is a security liability regardless of what the door spec sheet says.
We manufacture this product on our own lines, not through subcontractors. That means when you send us a spec, the tolerance discussion happens with the people running the CNC press brakes, not with a trading company relaying messages to an unknown factory.
Direct Manufacturer, Not a Trader
Spec tolerances are discussed with the CNC press brake operators — not relayed through a trading company to an unknown factory.
1.2mm SPCC Body, 1.5mm Frame
Gauge decisions are driven by field failure data — not cost-cutting. A 1.2mm door in a flimsy frame is a security liability regardless of the door spec sheet.
Volume SKU, Catalog-Ready

MOQ at a Glance
Steel Gauge and Frame Spec: Matching the Door to Your Market
The gauge you specify determines downstream performance, freight economics, and how your customers perceive the product after 12 months in service. Here is how we think about it.
Price-Sensitive Residential
Legitimate spec for ground-floor residential where buyers compare on sticker price and the security requirement is low. Not our recommendation for anything above that segment.
We have had buyers come to us after sourcing 1.0mm doors from other suppliers and fielding complaints about denting from routine use. The gauge difference is real and visible after 12 months in service.
Standard Recommendation — Most Applications
Our standard recommendation for most single security door applications. Resists localized deflection that causes lock bolt misalignment under impact — the most common forced-entry failure mode on under-spec doors.
For commercial applications — office building corridors, retail back-of-house, light institutional — specify 1.2mm with internal reinforcement channels at the lock zone.
Reinforcement channels are cold-formed steel inserts welded inside the door body at the lock and hinge attachment points. They prevent body deformation around hardware under sustained force.
Institutional, Government, High-Security Commercial
Meaningfully stiffer body. Hinge plates run 4mm instead of 3mm. Multi-point locking configured as standard. For the right market segment, the price premium is justifiable and your downstream customers will pay it.
Landed cost difference between 1.2mm and 1.5mm on a 200-unit order: roughly 15–20% on door cost, plus a freight increment from the weight.
Frame Spec: The Dimension Most Buyers Underestimate
Frame spec matters as much as door body gauge. Our standard single security door frame runs 1.5mm cold-rolled steel with three anchor points per jamb.
Masonry installation: Anchor bolt patterns matched to the frame depth.
Steel stud framing: Clip-angle kits supplied.
Pre-shipment fit check: Every door is test-fitted against its frame before packing — the fit is guaranteed.
This matters when your installers are running through a 100-unit apartment project on a schedule and cannot afford shimming time on every opening.
Where Single Security Doors Move: Market Segments and Order Patterns
Understanding where this product sells helps you evaluate whether it fits your distribution model or project pipeline. These are the segments driving single-leaf security door volume across our export markets.
Residential Construction and Renovation
Apartment developers and housing contractors typically standardize on one or two door SKUs per project — a single-leaf entry door for each unit, sometimes with a secondary interior secure door for utility rooms or storage.
For distributors serving residential contractors, a well-priced single security door in 900×2100mm at 1.2mm gauge is a catalog anchor SKU — it reorders predictably and the spec rarely changes between projects.
Commercial Office and Retail Fit-Out
Drives demand for single security doors with access control prep, vision panels, and architectural finishes. Order sizes are smaller per project but per-unit margin is higher because the spec is more complex and the buyer is less price-sensitive than in residential.
If you are positioned to serve commercial fit-out contractors or office furniture distributors, a single security door with pre-wired access control prep and a clean architectural finish is a differentiated product in most markets.
Institutional Procurement
Schools, clinics, government offices, social housing — single security doors move in large, predictable batches. Procurement cycles are longer and often require certification documentation, but once a spec is approved, the reorder pattern is reliable.
Supplying government contractors or institutional procurement offices offers the most consistent volume with the least price pressure once you are on an approved supplier list.
Replacement and Renovation
Single security doors are replaced more frequently than double doors because they take more daily cycling abuse — a residential entry door in a multi-unit building opens and closes hundreds of times per week.
The key is stocking the two or three sizes that cover 80% of standard rough openings in your market.
Distributors who stock a standard range of single security door sizes can capture replacement orders that do not fit the project procurement cycle.
Which Segment Fits Your Model?
Whether you are building a catalog anchor SKU for residential contractors, targeting commercial fit-out with higher-spec doors, or pursuing institutional approved-supplier status, the single security door product line supports all three paths. The spec, finish, and hardware configuration differ — the manufacturing source does not.

Customization: What You Can Specify, What Affects MOQ
Single security doors are one of the more customizable products in our line because the single-leaf format is simple enough that modifications don't require major tooling changes. Here's what's available and what the constraints are.
Size Customization
Width 700–1200mm, height 1800–2400mm. CNC program setup and frame roll-forming adjustment adds setup time that doesn't amortize on smaller runs.
Standard catalog: 800, 900, 960, 1000mm width × 2000, 2100mm height.
Panel Profile & Embossing
Modify the door face embossing pattern to match your product line's aesthetic. Standard catalog profiles include flat panel, single-panel raised, and multi-panel raised.
Most buyers choose from our existing profile library to avoid tooling cost.
Color & Finish
Any of our 60+ standard RAL colors at standard MOQ. Matte, satin, and gloss finishes all available within the standard color range.
Powder line changeover and color verification adds cost below 100 units.
Hardware Configuration
Lock grade, handle style, hinge count, and closer specification can all be adjusted. Hardware is pre-installed at the factory — field hardware installation is where most security door failures originate.
Vision Panel
Optional tempered or laminated glass insert, available in several standard sizes. Vision panels add to the door leaf thickness and affect container loading density slightly.
Access Control Prep
Conduit runs and junction boxes for electric strike, magnetic lock, or access control reader mounting — pre-installed at the factory. Send us the hardware system spec and we'll configure the door prep accordingly.
Factory pre-wiring is significantly cleaner than field modification. Field-drilled doors can void their structural warranty and create liability issues for the installer.

How We Build It: Process Details That Affect Your Downstream Quality
Here's what's specific to single security door production and why it matters for your order quality.
Steel Coil & Blanking
Door body starts as SPCC cold-rolled steel coil, blanked on the CNC laser cutter to ±0.5mm tolerance. Standard single-leaf body runs at 1.2mm gauge from approved mill sources.
Dual-source steel supply: We maintain dual-source supply on steel coil specifically because single-source supply on a high-volume SKU creates lead time risk when a mill has a production issue.
CNC Press Brake Forming
Blanked panels go to the CNC press brake for forming. The door face, back panel, and internal reinforcement channels are all formed in the same setup sequence to keep the dimensional stack consistent.
Welding: Robotic MIG + Manual TIG
Robotic MIG on perimeter seams. Manual TIG on hinge plate attachment and lock zone reinforcement. Hinge plates use full-perimeter welds — not tack welds — with 3mm plate on standard configurations.
Perimeter seams
Robotic MIG
Hinge & lock zone
Manual TIG
Zinc Phosphate Pre-Treatment
Weld seams are ground flush before the door enters the zinc phosphate bath. This step prevents powder coat adhesion failure at the weld line.
Why this matters: The most common finish defect on competitor product is bubbling paint at the weld seam within 12–18 months. The fix is straightforward but adds process time — which is why some factories skip it.
Automated Powder Coating
Powder coating applied after zinc phosphate pre-treatment. The pre-treatment step is what ensures long-term adhesion — particularly at weld seams and formed edges where adhesion failure typically originates on lower-process product.
Final Assembly & 100% Inspection
After powder coating, every door goes through final assembly: frame fit check, hardware installation and cycling, squareness check, and gap consistency measurement.
Process Transparency for Procurement Teams
The process details above are the ones that separate durable product from product that generates warranty claims at 12–18 months. If you're evaluating suppliers, these are the questions worth asking: dual-source steel supply, full-perimeter hinge welds, weld seam grinding before pre-treatment, and 100% outgoing inspection.
We publish these details because buyers who understand the process make better sourcing decisions — and because we're confident our process holds up to scrutiny.
Packaging, Container Loading, and Landed Cost
Single security doors ship in KD (knock-down) flat-pack format as standard — door leaf, frame sections, and hardware packed separately in reinforced double-wall corrugated cartons with foam corner protection. This format has two commercial advantages: it maximizes container utilization, and it eliminates the lock misalignment problem that affects pre-hung assemblies packed under load in a container.

Single Security Door FAQs
Decision-support answers for importers, distributors, and project buyers evaluating single security doors for their sourcing programs.
What is the standard size for a single security door?
The most common standard sizes are 900×2000mm and 900×2100mm for residential applications, and 1000×2100mm for commercial. These cover the majority of standard rough openings in most markets. We stock tooling for 800, 900, 960, and 1000mm widths at 2000 and 2100mm heights — these run at 50-unit MOQ. If your market has a different standard opening size, we can produce custom dimensions at 100-unit MOQ.
What steel gauge should I specify for a single security door?
For residential entry doors, 1.2mm SPCC cold-rolled steel is the market standard and the right balance of security performance and freight cost. For commercial applications — office corridors, retail back-of-house — specify 1.2mm with internal lock-zone reinforcement channels. For institutional or high-security applications, move to 1.5mm body gauge with multi-point locking.
Transparent trade-off: The 1.0mm option exists for price-sensitive markets but deflects under sustained force in a way that 1.2mm doesn't.
Single security door vs. double security door: which should I stock?
Single-leaf doors cover roughly 80% of standard residential and commercial openings. Double doors are specified for main building entrances, wide commercial openings, and applications where two-panel symmetry is an architectural requirement.
If you're building a starter catalog, single security doors are the higher-volume SKU and the lower-risk inventory position. Double doors carry higher per-unit value but slower turnover in most distribution models.
View double security door optionsWhat certifications does the single security door carry?
Our single security doors are manufactured under ISO 9001:2015 quality management system, CE-marked for European market conformity, and SGS third-party audited. For the North American market, there is no single mandatory federal certification for standard security doors (unlike fire doors, which require NFPA 80 listing). We configure hardware to ANSI Grade 1 or Grade 2 as specified.
What is the MOQ for single security doors?
50 units for standard catalog sizes and configurations. 100 units for custom sizes, non-standard panel profiles, or custom color matching outside the RAL library.
Sample orders available: Below 50 units, we can discuss sample orders of 2–5 units for product testing and market evaluation — most new buyers in this category start with a sample order before committing to a container.
Can single security doors be pre-wired for access control?
Yes. We pre-install conduit runs and junction boxes for electric strike, magnetic lock, and access control reader mounting during factory assembly. Send us the hardware system spec — the access control brand and model, or the electrical prep drawing — and we'll configure the door accordingly.
Why factory pre-wiring matters: Factory pre-wiring is cleaner than field modification and avoids the structural warranty issues that come from post-installation drilling.
