Hollow metal frames are made from sheets of steel that have been folded into a rectangular shape. The resulting frame contains a hollow space that can be filled with insulation to enhance the thermal properties of the structure. Let's take a closer look at the different types of hollow metal frames and their applications.
1. Knockdown Frames
Knockdown frames, also known as KD frames, are versatile and adaptable frames that are customizable to fit a variety of different door sizes. They are also known for being easy to assemble and disassemble, making them ideal for buildings undergoing frequent renovations.
2. Welded Frames
Welded frames are precisely what the name suggests- frames that are welded together at the corners. These frames are known for being very sturdy, making them one of the most common selections in high-traffic commercial buildings. Welded frames require a bit more skill than knockdown frames when installing, but they are still relatively easy to install.
3. Pocket Frames
Pocket frames are a specialized type of hollow metal frame that is used for sliding pocket doors. These frames are often used in interior design because they are functional as well as visually appealing. They hide the door frame from view when the door is slid inside the wall cavity.
4. Positive Pressure Frames
Positive pressure frames are built to withstand the impact of a blast or explosion, which makes them ideal for government buildings, banks, and other buildings that need to enhance their security. They are designed to keep the door in place during extreme pressure changes, which helps prevent further damage to the structure.
5. Temperature Rise Frames
Temperature rise frames are frames that have been tested and certified to the requirements of the International Building Code. These frames are constructed of materials that will not warm up to a temperature that can accelerate the spread of fire beyond what was originally designed for the structure.
The Bottom Line
