A header is a beam that spans the opening for a doorway, window, skylight, or stairway. In general, workers in the construction industry refer to large beams as girders. If it is the chief horizontal support in a structure, it is a girder, not a beam. If it is one of the smaller structural supports, it is a beam.
What is the difference between headers and girder beams?
Headers and ceiling joists typically run smaller than floor joists, in terms of lumber width. Girder beams are larger, wider, and thicker. Primary horizontal support beam in a structure. Supports all other beams and columns. Supports all horizontal loads in a structure, from the basement to the roof.
What is a double header beam?
The header is a beam that runs across the top of a framed window or door opening. This double header is a beam that supports the floor joists to allow for stairs.
What is a header on a building?
For more information see our disclosures here. A header is a beam that spans the opening for a doorway, window, skylight, or stairway. Though the word “header” dates back to 15th-century England as the name given to an executioner, its earliest use as a building term occurred a couple of hundred years later.
How are beams supported on a wall?
A beam may be supported by another beam or vertical posts. In the case of joists, loads are transferred to another beam – the girder. Headers, which span openings, transfer loads to wall framing – studs, which transfer loads to joists, which transfer the load to girders and down to the posts.
What is a lintel header?
Where is the drop beam in a 2nd floor joist?
Can a bearing wall carry joists?
What is a header in a building?
A header is a beam that spans the opening for a doorway, window, skylight, or stairway. Though the word “header” dates back to 15th-century England as the name given to an executioner, its earliest use as a building term occurred a couple of hundred years later. It did—and still does—refer to part of a stone or brick wall.
What is a header in wood frame?
Today, that term has been adopted to the parts used in wood-frame construction. Now, the word header refers to a beam-like support in wood-frame construction. The header spans an opening for a window or door, or it is a cut-out in the roof or floor for a skylight, chimney, or staircase. Typically at least twice the size ...
What is a header in a brick wall?
It did—and still does—refer to part of a stone or brick wall. It is a brick or stone that bridges an opening. The header is placed with its end, or head, facing the wall, a practice that fortifies a wall’s construction. Today, that term has been adopted to the parts used in wood-frame construction. Now, the word header refers to a beam-like support ...
How many studs does a header have?
Typically at least twice the size of surrounding framing members, a header is often built up from two studs, joists, or rafters. It runs between full-length supports and, along its length, carries the loads of the shorter studs, joists, or rafters that terminate at the opening.
What to know before choosing a header?
Before deciding which header or lintel you will use and the kind of material you will choose, make sure that you have properly identified if the wall is load-bearing or non-load bearing. This is important as you would not want to get a support that will not serve its purpose and will just be a waste of your resources.
Why are headers and lintels used interchangeably?
The terms header and lintel are often used interchangeably because they somehow have a similarity in how it functions. Essentially, headers and lintels are mostly the same. Most people in the United States use the word lintel, while in some parts they are also called a header. Both of them do the same job. They are beams that mainly function ...
How are a lintel and header similar?
Both of them are structural members that are made to bear not only their load but also the other weight they have to carry. Lintels and headers function to support the weight of the specific part of the building they are placed in.
Why are lintels and headers used in construction?
In general, lintels and headers are used in construction to support the load-bearing and non-load-bearing walls. They are mainly placed above the openings inside a building or home. This is because openings need to have additional support as it can be heavy to maintain the integrity of a building if it does not have any material to help sustain the weight from above. Examples of openings are windows, doors, and even fireplaces.
Do headers have to follow codes?
In some locations, headers must follow the required codes set by their local construction standards.
Can headers be made of material?
Both headers and lintels can be made of any material and can also be customized to fit any dimension of a specific opening. Many homeowners want to have contractors specifically make their beams, but ready-made ones are also available and can be bought from commercial suppliers. CLICK TO CALL.
What Is a Beam?
The beam is a primary part of a structural framing system specifically designed to carry distributed loads such as parallel walls or roof systems . The beam is one of the most commonly designed elements of a structure in engineering to resist load, & its primary mode of deflection is bending. It is mainly used to resist bending moments, vertical loads, and shear forces.
What is beam in framing?
Basics of Beam: Beams are a primary part of structural framing systems designed to carry the distributed load of any structure. These are the most commonly designed elements of a structure to resist beam load because its primary mode of deflection is bending.
What is a girder?
The girder is basically a beam that supports other small beams and serves as the main horizontal supports of a structure. Unlike beams, the girder is designed to support major concentric loads such as columns or beam reactions, and their load carrying capacity is much higher than that of beams. It can be made from various building materials such as ...
What is the difference between a girder and a beam?
Difference Between Girder and Beam. The main difference between a girder and a beam is the size of the component. In general, workers in the construction industry refer to large beams as girders. If it is the chief horizontal support in a structure, it is a girder, not a beam.
What is a beam that supports other small beams called?
A beam that supports other small beams is commonly called a girder; while it is still a beam, its load-bearing capacity is much greater than a beam and is designed to support key parts of a structure.
What is a beam used for?
It is mainly used to resist bending moments, vertical loads, and shear forces. Thus, beams are defined by their bending moments that are calculated for the primary requirements to form the structure. In simple terms, any horizontal structural member that undergoes lateral loads and is able to sense the load is a beam.
What are the different types of beams?
They are classified based on the kind of support the beam provides – simply supported, fixed, continuous, cantilevered, and trussed beams. They are also classified on the geometric aspect as straight, curved, and tapered beams.
What is an engineer beam?
Engineered. Engineered beams use factory-made wood products or dimensional lumber as trusses to create beams used as girders, joists, or other types of the beam. They are most often found in home joist construction.
What is a Beam?
A beam is a horizontal, load-bearing member in a structure. Beams are not to be confused with posts, which are vertical and support a beam. All homes have beams, and most homes will have many different types of beams, including joists, girders, and headers.
What is a Girder?
A girder is the main beam in a structure, supporting all other beams. As such, the girder is usually the largest and strongest beam in any structure. Girders are always supported by vertical posts, which sets them apart from other beams, which are always supported by a girder. They are often dimensional lumber or steel I-beams in home construction.
How are girders and joists related?
Joists and girders are related in that the girder beam always supports the joist beams. They are also always perpendicular to one another. Joists span the width of a structure, while girder beams span the length of the structure. While that rule doesn’t always apply, it is the most common outlay for those two member types.
What is a steel beam?
Steel. Steel beams, such as I-beams or Z-beams, are used as girders or as open-webbed joist beams in commercial and industrial applications . Many homes feature I-beam girders, which are exceptionally strong and require fewer vertical posts.
Why are girder beams important?
Since we now know that there are many types of beams in a house, it is critical to understand that girder beams are the “main beam” in a house and are identified because they are always supported by vertical columns. Joists are always supported by a girder.
What type of material is used to build a beam?
There are many different types of materials used in constructing a beam. The main factor is what type of beam is being fabricated and in what type of structure. Bridges and large commercial projects will use, almost exclusively, steel. On the other hand, most homes feature beams that are all some type of dimensional lumber. Let’s take a look at the various types of beam material below:
What is header in text?

What is Beam?
Beams are one of the most common structural members that are typically horizontal although they can have any orientation . Beams are large horizontal members that carry the floor loads from the floors, walls, or roofs to the columns or foundation walls. Floor joists rest directly on beams. Walls and columns often sit on floors, so they may rest indirectly on beams. The function of a beam is to provide to straight, level surface, even with the top of the mudsill, which will support the floor joist system between the foundation walls. They are traditionally made of wood or steel, but are also made of engineered wood these days. The term girder is often used interchangeably with beam in residential construction works.
How do beams work?
Beams transfer their loads vertically to columns or foundations. They may receive their loads on a vertical or horizontal face. Joists rest on top of beams or may be fastened to the sides of beams. The standard size of a beam used in a building is 9-by-12 inches (230 mm x 300mm), mainly used in residential buildings. Theoretically, a beam could be of any length as long as it is designed properly. There is no standard size of joists used for ceilings in residential or industrial buildings, however, most average homes use ceiling joists in a board size of 2-by-6 inches and can go up to no larger than 2-by-12 inches.
What is the purpose of beams and joists?
Beams are the most common structural element used in construction or building works to carry the floor loads from the floors, walls or roofs to the columns or foundation walls. They are typically horizontal but they can have any orientation that better serves the purpose.
What are structural members?
Structural members play a vital role in choosing the structural system for a building. Joists and beams are structural members that are used to frame buildings. Let’s discuss the two in detail and understand the difference between the two.
What is a joist made of?
Joists are typically made of several smaller size beams that run parallel to support horizontal structures such as floors, ceilings, or decks. Joists have a high strength-to-weight ratio, which make them a preferred choice of material in building long spans and multi-storey structures.
What is a beam joist?
Beams are horizontal, load-bearing structural members that bridge an area and along with columns and posts, they protect the structural integrity of both residential and industrial buildings. Beams are used almost everywhere – from ceilings to floors, walls to roof, and decks to garages.
What is a joist?
Joists are basically a horizontal structural member that runs across an open space. Their function is primarily the same as beams, except joists are supported by wall framing, foundations, or beams. Joists usually run between walls or rafters to support a ceiling or floor.
What is a lintel header?
Lintels and headers span door and window openings.
Where is the drop beam in a 2nd floor joist?
The load path is a bit unusual. 2nd floor joists lap dropped beam in top of 1st floor wall. Dropped beam is supported by a column at either end within the 1st floor wall. Basement wall below is only partial and load continues down via columns.
Can a bearing wall carry joists?
I'd just call it a beam. But if it's in a bearing wall, I'm not sure of the point. A bearing wall should be able to carry joists sitting on top of it. Particularly if you line up joists and wall studs (should be easy to do).
