Light 3 - Single (Cold Weather + Thermal Break) | Steel French Doors

Our measurements include the entire door & jamb. We measure our iron & steel doors from the outside of each part of the jamb/frame.

For example, a 38"x 96" single door will include the jamb in this measurement. We recommend a rough opening to be at least 1" wider and 1/2" taller than the iron door to allow for movement when installing the iron door. 

Inswing means that the door opening is inside the house. Outswing doors open to the outside and are used mostly for patio doors or storefronts to meet building codes.

When facing the door from the outside of house, left hand inswing means the left door opens into the house.

When deciding between left and right inswing, this will depend on your house layout and is a preference to the customer on which direction they want the primary door to open.

We use the highest quality 12 gauge steel with 5/8" scroll work to make our iron doors. Many other steel door companies use 14 or 16 gauge steel, which is 30-50% lighter, dents easily, and has less insulation.

All of our steel security doors are built to last decades and are built to withstand some of the toughest weather conditions

We use 5/8" tempered dual pane glass with glass already installed in our wrought iron doors. For custom exterior iron doors, we have over 10 different glass options. 

Rain glass & Low E clear glass styles tends to be the most popular, but we also have aquatex, reed, frost, etc. If you find an in-stock steel door style you like but want a different glass style, we can create a custom iron door order.

Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass.

Tempering puts the outer surfaces into compression and the inner surfaces into tension. Such stresses cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards as plate glass (aka: annealed glass) creates. The granular chunks are less likely to cause injury.

Both of our modern steel doors & wrought iron doors are pre-hung meaning the jamb, door, glass, flush bolt, roller latch, & sweep is included.

Only handles, installation bolts and installation are not included to allow customers to choose their own lock and installer.

Our wrought iron & steel entry & interior doors are made from the highest quality 12 gauge steel so they are very heavy.

A single 3' x 8' foot iron exterior door will weigh around 400 pounds with double doors weighing around 800-1000 pounds.

Yes, we can make any design, glass style, color, and size of steel & wrought exterior iron doors.

We provide a CAD drawing before production and a deposit. Please note, due to high backlog, custom order can take anywhere from 16-22 weeks.  
To order a custom door contact us at info@blackdiamondirondoors.com or view our custom page below. 

We recommend ordering a custom thermally broken iron or steel door for northern climates where the temperatures change drastically in the wintertime or where temperature is below freezing. 

We can make almost any design into a thermally broken door, except bi-fold and sliding doors. 

Our thermal break technology separates the inside & outside surfaces of the steel with composite material throughout the door, glass, & frame which protects the inside of the door from the cold temperature on the outside of the door.

This results in the inside & outside of the door being thermally separated or "broken" which provides greater improvement in insulation.

Yes, contractors, builders, developers, and other door companies often purchase our single & double iron entry doors and then sell to their own clients. You could be paying more at another iron door company and still be receiving one of our wrought iron entry doors.

No, we are a distributor of wrought iron doors & steel windows throughout North America but do not install iron security doors. However, our customers can easily install our pre-hung doors or find local contractors in their area for installation.

We have an easy step by step installation guide that will show you or your contractor how to install our wrought iron exterior doors.

It is recommended that you have at least 2 other people to help with the installation as our iron doors are very heavy.

We ship to all 48 states and shipping usually takes only 4-10 days for in-stock iron doors depending on location and carrier.

The carrier provided will call to schedule a delivery date and time to deliver your door.

Important: Because the doors are heavy, the customer is responsible for unloading the door from the delivery truck.

Iron door shipping cost will depend based on location and the number of doors ordered. Multiple door orders, doors with transoms, or doors larger than 8' can have shipping cost estimated at the time of quote. 

For Texas residents, we offer free local pickup from our Houston warehouse. We also offer local deliveries if less than 75 miles from our warehouse.

We provide a liftgate when possible. However, many of our steel security doors are too big to fit on a liftgate so you will need 2-3 people to dismantle the pallet and unload the doors once delivered. 

Yes, we offer free local pickup from our warehouse in Houston, TX. We will load the door onto your truck free of charge.

Our iron doors are packaged in individual wooden crates and secured to a custom pallet to prevent damages made by shipping carriers.

Note, you will need 2-3 people to help dismantle the pallet once delivered curbside.

Our iron security doors are made from the highest quality 12 gauge steel so they are extremely heavy. 

A 3' x 8' foot single iron door will weigh around 400 pounds with 6 x 8' double iron doors weighing around 800-1000 pounds.

All of our in-stock iron doors come with a 6" jamb which fits the standard 2x4 wall studs.

If you have 2x6 wall studs, you might be better offer ordering a custom door with an 8" jamb, however a 6" jamb will still fit a 2x6 wall but a trim kit will likely be needed. 

Jambs are included with all wrought iron & steel door purchases.

We use 12 gauge iron tubing for all iron & steel doors. Jambs are packaged separately from the iron door when shipped to prevent any damage.

Our steel jambs & doors are fully insulated with polyurethane foam so that our doors are climate controlled and do not let heat in or escape from the house. We have shipped doors to all 48 states and do not have problems with our insulation like others. 

For peace of mind for our Rockies & Northern Midwest customers, we can offer a thermal break option for even better insulation on custom steel & wrought iron door orders. 

A steel threshold is included with all exterior iron door purchases and is already welded onto the jamb.

For modern interior steel doors, we can make without a threshold as this is standard for interior doors.  

We make iron door jamb installation simple by welding tabs with pre-drilled holes on the jamb.

Once the jamb is level, just drill bolts into the mounted tabs with pre-drilled holes. Next, hang the iron door slabs are your door is complete.   

Because there are many different handles and locks to choose from, we do not include handles and locks with in-stock iron & steel doors. However, these may be purchased from us separately. Our iron steel exterior & interior doors are compatible with most major lock-set brands and smart locks.

However, if you like the traditional iron pull handles that do not have latches, we can make those with a custom order. 

All of our in-stock iron doors come with two pre-drilled bore holes, unless otherwise specified.

A 3rd hole may need to be drilled for certain hardware by your installer. 

Locks will need to be installed after iron door installation to prevent damage during shipment. When purchasing a lock-set from a 3rd party such as Schlage, Baldwin, Weslock, Emtek, etc., please use the following measurements below:

Door Specs: 
Bore hole: 2 1/8"
Back set: 2 3/4"
Center to center: 5 1/2"
Door Thickness:
2" - Exterior Doors)
2 3/8" - Thermally Broken Exterior Doors (Only Certain Brands Can Accommodate This, Please Contact Us For Details)
