A fire door is a door with a fire-resistance rating (sometimes referred to as a fire protection rating for closures) used as part of a passive fire protection system to reduce the spread of fire and smoke between separate compartments of a structure and to enable safe egress from a building or structure or ship. In North American building codes, it, along with fire dampers, is often referred to as a closure, which can be derated compared against the fire separation that contains it, provided that this barrier is not a firewall or an occupancy separation. All fire doors must be installed with the appropriate fire resistant fittings, such as the frame and door hardware, for it to fully comply with any fire regulations.

Because a fire door needs to resist the spread of flames and smoke for a certain amount of time, it has high requirements to the door frame and hardwares. As we know steel fire door manufacturing process includes steel sheet cutting, embossing steel door sheet, cutting sheet into suitable size, bending door sheet and frame, punching necessary holes, assembling and welding door panel, hot processing door panel, powder coating and transfer printing doors.

From the whole process, steel sheet cutting is the first and the most improtant step, in order to ensure the whole door manufacturing presicion, metal laser cutting machine has been introduced to this industry.
Laser cut doors are cut by a fiber optical laser resulting in a very precise uniform design. Not only can this method of design be used on a multitude of metals of various thickness, it can also be repeated easily with the exact same specifications.

With laser cut doors there is no variance in the measurements, meaning that if you cut 50 doors at a specific measurement they will all be exact copies. Fire doors with this level of precision offer many advantages and benefits.
Adavantage 1: Greater Durability
Laser cut doors are very precisely cut. Because they are cut from a single sheet of metal, there are less parts involved when one is assembled. Fire doors cut and designed by hand often need more moving parts and joints to be properly assembled. Because laser cut doors are cut to fit from a single sheet and with exact measurements, there are far less parts and fewer joints.
What this means for you is you have fire doors that are far more reliable and durable. The more moving parts and joints an fire door has, the greater odds it has of failure. This is simply due to having more parts that can wear out or break. By having less points of risk, laser cut doors are far less likely to break.
Adavantage 2: Aesthetically Pleasing
Fire doors are a necessity for your business, but they don’t need to be unsightly or distracting. A laser cut fire door presents a single solid front that is minimalistic and smooth when it is closed. Other doors built out of separate sheets often have more noticeable lines and joints causing them to stand out more.
While on the surface this may not sound like much, it is important. The aesthetic of your building has an effect on all of its employees and guests. A disruption to the interior environment can be distracting and noticeable. When your fire doors blend into your building, it creates a much more seamless and soothing environment for employees and guests alike.
Adavantage 3: Easy To Replace & Duplicate
Lastly, the greatest benefit of laser cut fire doors is how easy they are to replace. When you order a laser cut door with the exact same measurements as the door you are replacing, you are getting an identical copy. This makes installation of the new door far easier as you don’t have to recut or remeasure the area the door is mounted in. It simply slides in and attaches exactly the same as the old one. This greatly saves on time and aggravation.
