Q235B gable frame steel structure building
Steel structure building
Steel structure building is a kind of building made of metal, mainly used for internal support and external material steel structure. Steel frames are used for horizontal beams and vertical columns, which are hinged together by welding processes or strong bolts and rivets.
The horizontal steel beam is designed to bear the load placed at its entrance, while the vertical steel column is used to handle some of the compressive load applied to it.
This is one of the most reliable structural forms because it can withstand heavy loads. Therefore, steel structures can be used not only in buildings, but also in a variety of applications. They can also be used to build bridges and other infrastructure, such as airport terminals and factories.
Different sizes of steel profiles are used in steel structure buildings, and these steel profiles can be cold rolled or hot rolled.

Steel frame type
Customers can choose various steel frames. Here are some products sold in the market:
Span frame
For a long time, the gapless frame has proven to be one of the most reliable frames in the construction industry due to its versatility, durability and strength. They are also economical to install, which is why people with tight budgets usually prefer it.
This type of steel frame can be used without internal support and is very suitable for larger and wider areas such as warehouses and factories. Any type of building or storage facility can benefit from the use of clear span frames.
It is also universal because it can be partitioned to meet user needs. There are no load-bearing walls to consider, so the layout of the space can be rearranged as needed.
Modular framework
This differs from the clear frame in that it has an internal cylinder that provides additional support to the structure. Because it helps to evenly distribute the load, it can save the builder a lot of money on the foundation and structural frame. For larger and wider buildings, especially those with a width of more than 80', the modular frame is considered a good choice.
Monoclinic frame
Since the height of the eaves of the side walls is higher than the rest of the building, it produces a slanting effect that extends from the front to the back. Builders can make it steep according to their preferences. It is usually used in offices, shopping malls and small warehouses. It also has columns such as a modular framework. This frame can be used for small and medium-sized buildings. The inclined design of the roof structure also makes it look more beautiful.

Advantages and disadvantages of steel frame structure
There are many reasons why you choose a steel frame structure. First, it is very strong and versatile. It can be used to build smaller buildings, but it can also be used in a wider, wider space, such as a warehouse. It is more environmentally friendly because steel can last a long time and can be manufactured. You can build buildings without purchasing materials such as wood. It is more affordable and easy to install, which reduces downtime for many companies.
One of the disadvantages of steel frame structure is its high thermal conductivity. Steel is a good conductor of heat, so in summer, unless the building is insulated, steel becomes very hot. When using low-quality steel, the steel is also prone to corrosion.
Steel structure building design
There are three basic steel structure building designs and methods to choose from. The first is a simple design structure. This is the most basic and traditional design of steel structure, and it is also the design commonly used by the company. This type of design is the best in resisting lateral loads. Some form of support is used to provide greater stability and anti-shake. A concrete core can be added to multi-story buildings.
When building a simple design steel structure, the contractor must be made aware of the common reaction. Since the joint is the joint that holds the structure in place, it must provide maximum support.
Another type of design is called continuous design. In this type of design, the joint is made more rigid, so that the moment is transferred to the component in a balanced manner. Frame actions such as column and beam bending are actions that provide stability to the frame and prevent shaking. In this type of design, computer programs and software are usually used to set up the design because it is usually more complicated.
The third type is semi-continuous design. This is the most complex type of design because it can more realistically represent the joint response of the structure. It requires advanced computer programs to determine the connection behavior.
