Steel Door Fabrication and Care Details


Steel doors contain a foam inner layer and a steel shell. Steel has a lower carbon content than iron and will necessitate a lower casting temperature. This makes steel a more cost-effective metal. Consider the structural steel fabrication processes that a residential door may undergo and select some custom features for your new steel entryway door.

Foam and Steel Prep Steps

A foam layer is often sized to match the measurements that most residential and commercial doors possess. A steel door does not have to be a typical size, however. A garage door or another door that will be used to seal off a tall and wide entryway may also be constructed of foam and steel.

The steel fabrication process involves mixing a batch of steel and baking the components in a heating vessel. Steel is resilient to a wide range of weather variables. Because of the weight of steel, the metal is typically only used as the outer shell of a door. If solid steel were used to produce residential and commercial doors, the extreme weight of a door could tear the door off of its hinges.

Custom Components

Steel is typically used with other materials. A steel door could be designed entirely with a steel outer shell, but it is fairly common to have glass inlays or trim pieces added to a steel product. Because a steel door would be difficult to cut through, it is important to plan upon the types of features that a custom door will possess.

During the fabrication process, a manufacturing crew will use machining strategies to create holes, cutouts, notches, and other details on both sides of a door. Materials that will be added to steel may require the use of hardware or a soldering process, to provide a door with its functional and design elements.

Care Techniques

A steel door should be installed by a technician who has experience working with this type of metal. Steel can become scratched, if sharp tools are used to secure a door to its hinges. After a door is hung properly, it will require infrequent cleaning sessions. The inside of the door will maintain its beauty, due to the color of the steel. The exterior side of a door may occasionally need to be wiped off with a cleaning agent and a sponge or a cloth. Moisture can corrode untreated steel. A manufacturer may use a sealant to preserve new doors.

investing in a stretch wrapper to reduce packaging time

Do you spend a lot of time wrapping pallets or bulk items for shipping? Wouldn't it be nice if you didn't have to spend all of your time walking circles around those items before you could send them out to be shipped? If so, now is the time for you to learn about stretch wrappers for your bulk items. I didn't have one of these machines until recently, and it has really helped reduce the time it takes for me to prepare things for shipping. Hopefully, the content on my site will help persuade you to make the investment and reduce the time it takes for you to prepare your things to ship.
