What are CDI Doors Commercial Security Metal Doors?

CDI Commercial Security Metal Doors are configurable physical door-and-frame products for commercial openings. The standard security metal door uses 18-gauge steel, is 1-3/4 inches thick, and carries an SDI Level 2 Heavy Duty classification. Buyers can also choose 16-gauge steel.

The word security needs context. These core specifications closely match CDI’s broader hollow metal door line. In other words, the label describes the door’s use as a durable commercial barrier, not a distinct ballistic or tested forced-entry tier. Buyers who need a specialized protection rating should ask CDI for documentation for the exact opening.

Steel Door Institute guidance defines SDI Level 2 as Heavy Duty construction with an 18-gauge minimum, one level above Level 1 Standard Duty. That is a meaningful commercial classification, but it does not by itself promise ballistic protection or a particular forced-entry test result.

 

Who are CDI security metal doors designed for?

CDI targets contractors, facility managers, business owners, and specifiers working on exterior entries, replacements, fire-rated openings, and other heavy-duty commercial applications. Listed property types include offices, retail spaces, healthcare facilities, schools, warehouses, and multifamily buildings.

CDI is most relevant when the main need is a durable physical opening. Buyers who also need mobile credentials, visitor entry, video, or remote management must plan for separate, compatible access-control hardware.

 

CDI Doors specifications at a glance

Specification	CDI Doors offering	What it means for buyers
Steel construction	18-gauge standard; 16-gauge optional	The standard door meets the SDI Level 2 Heavy Duty gauge threshold; 16-gauge adds a thicker face sheet.
Door thickness	1-3/4 inches	This is the listed thickness for the commercial metal door configurations.
Standard sizes	24–48 inches wide and 80–96 inches high	Larger openings require a custom order.
Core choices	Polystyrene: R-6.54 and STC 25; honeycomb: R-2.38 and STC 31	Polystyrene has the higher listed insulation value, while honeycomb has the higher listed sound rating.
Fire protection	20 minutes to as much as 3 hours, by configuration	The required rating must match the complete opening assembly.
Hardware preparations	Cylindrical, mortise, deadbolt, and reinforced panic-device preparations	Buyers can select common commercial locking and egress hardware formats.
In-stock lead time	3–5 business days	Standard openings may arrive faster than custom sizes or configurations.

 

How do CDI door construction and configurations compare?

CDI starts with an 18-gauge flush steel door and lets buyers add glass, ventilation, a fire rating, thicker 16-gauge steel, or a double-door layout. The right choice depends on visibility, airflow, code requirements, opening size, and the hardware package.

The doors use hemmed interlocking seams and reversible hinge plates for left- and right-handed arrangements. Core options include insulated polystyrene and rigid honeycomb. Standard preparations support cylindrical locks, mortise locks, deadbolts, and panic hardware.

Glass, louver, and fire-rated options

Glass kits add visibility without changing the door’s basic role. CDI lists vision, narrow, half-lite, and full-lite formats in several glass types, including fire-rated glazing for suitable openings.

A louver adds airflow, but CDI states that louvers cannot be used on fire-rated doors. If an opening needs both fire protection and ventilation, the ventilation plan must sit outside the door leaf.

CDI’s general product information describes fire protection up to three hours. Its fire-rated door page emphasizes 20-, 45-, 60-, and 90-minute options. Buyers who need a three-hour rating should ask CDI which door, frame, core, glazing, and hardware combination carries the needed listing.

 

What security capabilities are not included?

CDI’s security metal door is a physical barrier with common lock preparations. The door itself has no internet connection, mobile credential, video, visitor-management workflow, access log, or remote administration feature.

That distinction matters for multifamily and commercial properties. ButterflyMX can add a separate digital layer with access control, smartphone entry, visitor access, wallet-based credentials, and video intercoms. A physical door and a digital access system solve different parts of the same entry decision, so the opening, lock, credential, and egress hardware need to work together.

 

How much do CDI Doors security metal doors cost?

CDI lists in-stock security metal door kits from $384. It does not publish a full price range, so buyers need the online quote builder to price their selected size, gauge, fire rating, glass or louver kit, and hardware.

The $384 figure is a starting hardware price, not a complete installed-project price. A final budget may also include the frame, hinges, lock or panic hardware, shipping, field-applied finish paint, and professional installation.

For market context, CDF Distributors lists comparable commercial metal doors at $416.30 for a plain example, $571.38 with a lite kit, and $567.10 with a louver. Those figures suggest CDI’s $384 entry point is competitive, but they cannot predict the price of a matching CDI configuration.

 

What affects the final project cost?

• Opening dimensions: Standard sizes may qualify for in-stock pricing, while larger openings require custom work.
• Steel gauge and fire rating: The 16-gauge option and rated assemblies change the configuration.
• Glass or louver kits: Cutouts and inserts add scope, and louvers cannot be paired with a fire rating.
• Hardware and frame: Lock, panic-device, hinge, and frame choices affect the complete opening.
• Freight, finishing, and installation: Shipping, finish paint, and labor may add project cost. CDI does not publish a standard installation price.

 

What do customers say about CDI Doors?

Customer sentiment is generally positive, though the rating distribution includes a meaningful group of poor experiences. Birdeye lists CDI Doors at 4.5 out of 5 from 77 reviews, including 65 five-star reviews and nine one-star reviews.

Positive comments commonly mention knowledgeable sales help, competitive prices, and an easy ordering process. Negative feedback includes shipping damage or delays and dissatisfaction with the resolution of at least one damaged order.

These are company-wide service reviews, not laboratory tests or product-specific ratings for the Commercial Security Metal Door. The pattern points to many positive sales experiences, while the one-star group makes careful freight inspection sensible. Photograph the shipment, note visible damage with the carrier, and report issues promptly.

CDI Doors has been BBB accredited since September 2, 2025. That is a useful company signal, though its formal history under the program is relatively short.

 

What should buyers expect from delivery and installation?

CDI says in-stock standard sizes ship in 3–5 business days and advertises expedited same- or next-day options. Standard doors range from 24 to 48 inches wide and 80 to 96 inches high; larger openings are custom orders with longer lead times.

Fast shipping does not remove the need to coordinate the opening. The door must match the frame, handing, hinges, lock preparation, closer or panic hardware, fire label, and wall conditions. CDI doors arrive factory primed, so a contractor must apply the finish paint on site.

Professional installation is recommended because commercial steel doors and frames are heavy and need accurate alignment. CDI is described on its independent business listing as providing door sales and installation, but buyers should establish availability, service area, scope, and pricing for their project.

 

A practical pre-purchase checklist

• Measure the rough opening, frame opening, door width, door height, and wall thickness.
• Document the required handing and swing direction.
• Decide whether the existing frame can be reused or must be replaced.
• Select the cylindrical, mortise, deadbolt, or panic-device preparation before ordering.
• Identify the required fire rating and make sure all opening components are compatible.
• Choose between visibility through glass and ventilation through a louver.
• Plan separately for access-control wiring, electrified locks, or other electronic hardware.
• Plan for unloading, immediate freight inspection, storage, installation, and finish paint.

 

CDI Doors review verdict

CDI Doors is a practical option for buyers who want a configurable, heavy-duty commercial steel door, a visible starting price, and relatively fast shipping for standard sizes. It is less complete for projects that also need electronic credentials, visitor workflows, video, or centralized access management because those functions require separate systems.

CDI is best suited to standard commercial openings where the buyer understands the required dimensions, frame, handing, hardware, and code rating. Projects deserve closer review when they need a three-hour fire rating, dimensions above 48 by 96 inches, both ventilation and fire protection, or a documented forced-entry or ballistic classification.

CDI Doors alternatives to consider

Buyers can compare CDI with other online commercial door suppliers that sell hollow metal doors, frames, hardware, and configurable openings. Compare the exact steel gauge, manufacturer, rating, frame, hardware preparation, lead time, freight terms, and installed scope—not just the starting price.

• CDF Distributors: Useful for buyers who want another online seller with published pricing for plain, lite, and louver door configurations.
• TruDoor: Offers commercial hollow metal doors from several established manufacturers.
• DoorMart USA: A national supplier of commercial doors, frames, and hardware with a broad catalog.
• Commercial Doors Online: Sells fire-rated and non-rated hollow metal doors with glass and louver options.

 

CDI Doors vs. ButterflyMX

CDI Doors and ButterflyMX address different layers of property entry. CDI supplies a heavy-duty physical door and compatible hardware preparations, while ButterflyMX provides a property access and security platform for managing how authorized users, visitors, and vehicles enter.

They are not direct substitutes. A property may need a compliant physical door plus an electronic access platform, with the lock, door, frame, credentials, and life-safety hardware planned as one opening.

Choose CDI Doors based on physical-opening needs such as gauge, dimensions, fire rating, frame, and hardware preparation. Consider ButterflyMX when the project also calls for mobile access, visitor entry, video intercoms, or coordinated access across multiple property areas.

What sizes does CDI keep in stock?

CDI lists standard sizes from 24 to 48 inches wide and 80 to 96 inches high, with a 1-3/4-inch door thickness. Larger openings require a custom order and may have longer lead times.

CDI says in-stock standard sizes ship in 3–5 business days and advertises expedited same- or next-day options. Custom dimensions and specialized configurations may require longer lead times.

 

Does CDI Doors provide installation?

Professional installation is recommended, and CDI is listed as a door sales and installation business. Availability, service area, project scope, and cost should be established for the specific job because installation is not included in the published starting price.

 

Do CDI security metal doors include smart access control?

No. CDI security metal doors are physical doors with common lock and exit-hardware preparations. Electronic access, mobile entry, video, visitor management, access logs, and remote administration require separate compatible systems.

 

What are the main alternatives to CDI Doors?

CDF Distributors, TruDoor, DoorMart USA, and Commercial Doors Online are relevant commercial hollow metal door suppliers to compare. Buyers should compare equivalent gauge, rating, size, frame, hardware, freight, and installation scope.

 

Final assessment of CDI Doors

CDI Doors may fit buyers who need a configurable heavy-duty steel door, standard commercial hardware preparations, and fast shipping for an in-stock opening. Its $384 starting price is useful for early budgeting, but a configured quote is needed to understand the complete door and project cost.

The central tradeoff is scope: CDI addresses the physical opening, not the digital process used to identify visitors, issue mobile credentials, manage permissions, or coordinate access across a property. Compare door suppliers on matching specifications, then evaluate electronic access as a separate but connected decision.

If your project also needs mobile access, visitor entry, video intercoms, or property-wide access management, consider ButterflyMX alongside the physical door and hardware plan. Contact ButterflyMX to discuss an access and security platform for your property.
