About metal door frame

Types of Metal Door Frame

A metal door frame is a framework surrounding a door made primarily of metal, usually steel or aluminum. It serves as the structural support for the door, allowing it to open, close, and secure a space. Door frames consist of several key components: the head, which is the horizontal top piece; the jambs, which are the vertical sides; and the astragal, which is a strip that can cover the seam between two doors on the frame.

The main purpose of a door frame is to provide structure and stability to the door, ensuring it operates smoothly and securely. Metal door frames are commonly used in commercial spaces and other high-traffic areas. These frames are durable, secure, and weather-resistant, making them ideal for external doors or areas requiring a robust door-frame system.

Metal door frames can be of different types based on how they are installed. Here are some of them:

  • Embeddable Frame:

    These frames are installed during the construction of a wall, so the frame is inside the wall. When the wall is finished, the frame is hidden. An embed frame is also called an embedded frame.

  • Welded Frame:

    These frames are put together by welding, which means melting the metal and making it one piece. A welded frame is often very strong.

  • Removable Frame:

    This type of frame can be taken out easily without damaging the wall. People used to call it a removable door frame.

  • Adjustable Frame:

    An adjustable frame can be changed to fit different wall thicknesses or sizes. This frame is good for replacing old frames.

  • Hollow Frame:

    This frame is made of thin metal, so it is light but still strong. Hollow frames are often used for interior doors.

  • Non-Metallic Frame:

    These frames are not made of metal. They are used when metal is not allowed, like in some fire-rated doors.

  • Frame for Single Door:

    This frame is for one door only. It has a simple design and is easy to install.

  • Frame for Double Door:

    This frame is for two doors. It is more complex because it needs to support two doors opening and closing together.

  • Frame with Transom:

    A transom frame has a small window above the door called a transom window. This frame allows more light to come through.

  • Frame with Side Light:

    Side light frames have windows next to the door called side lights. These windows make the entrance look nicer.

  • Special Frame:

    Sometimes, doors have special frames that do not fit into typical categories. These are called special frames.

Functions and features of metal door frame

Door frames are critical components of any door system. They serve as the foundation for the door, ensuring it operates safely and securely. Without a door frame, a door cannot function as intended.

Metal door frames are composed of various parts that work together to support the door and ensure it functions smoothly. These include:

  • Head

    The head is the horizontal top part of the frame. It connects the two sides of the frame and the top of the opening. The head ensures the frame remains square or the same distance apart at the top. The door hinges are attached to the head if it is a metal door frame for swinging doors.

  • Jambs

    The jambs are vertical sections of the frame. They are the sides of the frame that fit into the wall. The jambs bear the weight of the door. They are where the door hardware, like hinges and locks, are attached. The jambs are available in two types: hinge jamb, which supports the door hinges, and strike jamb, which holds the lock and door latch.

  • Sill

    The sill is the bottom part of the frame. It is the horizontal piece that the door swings or slides on. The sill supports the weight of the door. It is constructed from durable materials such as wood, metal, or vinyl. The sill is also called a threshold.

  • Striker plate

    The striker plate is a metal plate installed on the strike jamb. It reinforces the area around the lock and latch. The striker plate helps to keep the door secure when it is locked. It also prevents wear and tear on the strike area of the jamb. The deadbolt plate is a heavy-duty strike plate that is used with a deadbolt lock.

  • Corner brace

    The corner brace is a metal piece that strengthens the corner of the frame. It prevents the frame from twisting or separating. The corner brace is usually L-shaped. It is installed at the top corners of the frame.

  • Glazing bead

    The glazing bead is a strip that holds the glass in place. It is found in metal frames with windows. The glazing bead secures the glass and provides a finished look to the frame. It is available in different profiles, such as square or round.

  • Security mesh

    The security mesh is a feature found in metal door frames. It has a window. The security mesh is a strong wire mesh that is embedded in the frame. It prevents intruders from breaking the glass and entering the room.

How to Choose Metal Door Frames

When choosing the metal door frame to buy, consider the following factors:

  • Durability and Strength

    The primary purpose of a door frame is to support the entire door structure. Therefore, consider the metal frame's strength and durability. Ask about the metal frame's lifespan and how much weight it can carry. Consider getting galvanized steel door frames, as galvanized steel frames are more durable than regular steel due to the added layer of zinc that prevents rust and corrosion.

  • Quality of the Welds

    The quality of the welds can determine the frame's strength. A fully welded frame will be stronger than a frame with spot welds. When inspecting the frames, look for smooth and consistent welds.

  • Gauge of Steel

    The gauge of steel indicates the thickness of the steel. A lower number means a thicker gauge, such as 16 gauge steel, which is durable and suitable for commercial projects. A 16-gauge steel frame can withstand impact and harsh weather.

  • Opening Configuration

    Ensure the frame's configuration matches the door's opening. The frame should match the door's swing direction, the hinge placement, and the size. The frame can be single or double, depending on the door. A metal frame for a single door will differ from that of a double door, as it will be larger.

  • Hinges and Hardware

    Metal door frames are compatible with specific hinges and hardware. Ensure the selected hinge and hardware can support the door's weight. Consider using heavy-duty hinges for metal frames, as they provide better support.

  • Fire Rating

    Some metal frames have fire ratings. A fire-rated frame is a better option for areas like commercial kitchens and storage rooms. A fire-rated frame can slow the spread of fire and protect people.

  • Soundproofing

    Consider a frame with soundproofing features if the door needs to block noise. A soundproof frame has seals and designs that reduce noise transmission.

  • Easy Installation

    Look for frames designed for quick installation. Some frames come pre-welded, while others require welding. If the frame requires welding, ensure a qualified welder does it to get a strong frame.

  • Customization Options

    Many manufacturers offer customization options. If the door has unique features, work with the manufacturer to create a frame that fits the door.

Metal Door Frame_2 Q&A

Q1: Are metal door frames customizable?
