When installing Windows in houses, we often use two materials, steel and aluminum alloy, which are different in price and have their own advantages. Steel fire Windows or aluminum Windows which is better? What are the advantages and disadvantages of steel and aluminum Windows? How to buy aluminum Windows? Let us take these questions to understand which steel and aluminum alloy Windows.

The difference between steel fire Windows and aluminum alloy fire Windows:

1. Advantages of steel fire Windows

Steel fire Windows have 20 years of application history, the stability of its product performance is beyond reproach, and has been unanimously recognized by consumers. Windows made of this material are durable, strong and affordable, and used to be a common choice for many families. The thermal conductivity of plastic steel Windows is still relatively low, compared with wood Windows, aluminum alloy Windows and iron Windows, its sealing is better, some plastic steel fire Windows have good thermal insulation performance, aging resistance, and the appearance is not easy to deformation. Disadvantages are safety, anti-theft, poor ventilation; Discarded plastic steel Windows are difficult to deal with and not very environmentally friendly; The space is easy to rust, the sound insulation effect is poor, and the ordinary quality plastic steel Windows are easy to deform.

2. Advantages and disadvantages of aluminum Windows

The Windows made of this material have good fire resistance, good corrosion resistance, heat insulation and cold insulation. Long service life, can be used for about 50-100 years. Even if discarded, this material can still be recycled without causing any pollution to the environment. Aluminum Windows are rich in color, diverse patterns, light material, high strength, lighting is also quite good. The disadvantage is that the price is more expensive, the thermal conductivity is high, and the insulation is poor.

Aluminum window purchase skills

1. Look at the seal

When we buy, we should pay attention to its good sealing. If the sealing of the product is not good and the use of time is long, it is easy to lead to the dirt of the hollow layer, which will directly affect the beauty of doors, Windows and homes. If it is a brand of high-quality aluminum alloy Windows, they will use sealing strips in production, and then use advanced thermal sealing technology for sealing treatment, so that it can effectively play a dust-proof, waterproof, sound insulation effect.

2. Look at the production process

When purchasing, it is also necessary to carefully check whether its production process is exquisite. For example, whether there is no welding at the corner, whether there is open welding, missing welding and other phenomena. In addition, we have to look at whether the door and door frame are tightly closed, whether their gaps are uniform, and whether we are flexible when opening and closing.

Now common refractory Windows are: steel fire Windows, broken bridge aluminum refractory Windows, aluminum alloy refractory Windows and plastic refractory Windows, steel fire window refractory materials are generally referred to the practice of heat insulation fire Windows, broken bridge aluminum and other refractory materials are generally set in the window frame and window frame steel lining or aluminum foil to increase strength, and some are filled with castable to enhance the fire resistance. GB/T31433-2015 "General Technical Conditions for building curtain walls, Doors and Windows" Article 5.1.5: "External doors and Windows with requirements for fire integrity, At least one layer of plastic doors and Windows, steel-plastic composite steel-plastic co-extruded doors and Windows, aluminum-plastic co-extruded doors and Windows profiles used to strengthen steel or aluminum lines should be connected to a closed frame, and the Mosaic notched inside the glass should take measures to prevent the glass from falling off after "fire".

Socket welded pipe fittings are the parts that connect pipes into pipes, which have an important contribution and role in the connection and use of pipe fittings. According to the connection method, it can be divided into four categories: socket pipe fitting, thread, flange and welding. It is often made of the same material as the pipe. There are elbow (elbow), three-way, four-way pipe cross head) and reducing diameter (size head). The bend is used for the bend of the pipe; Tee is used where three pipes meet; A four-way used where four pipes meet; Reducing tubes are used where two joints of different diameters are joined.
