First, the basic knowledge of doors and windows profiles
1. According to the material classification: aluminum alloy windows, wood windows, aluminum wooden windows, broken bridge heat-insulating windows, steel windows, plastic steel windows, color steel windows, PVC plastic ester windows and so on.
2. According to the use of classification: balcony windows, wall windows, roof windows, screen windows, floor windows and so on.
3. Categorized by opening method: sliding window, casement window, internal opening and inverting window, folding window, lifting window, fixed window and so on.
Second, understand the aluminum profiles for windows and doors
By the aluminum alloy extruded profiles for the frame, frame stile, fan material made of doors and windows called aluminum alloy doors and windows.
Third, aluminum alloy windows and doors profiles models
There are six common aluminum alloy window and door models on the market, respectively: 90, 70, 60, 40, 38, 35, etc. These models are generally based on the actual width of the main frame of the aluminum alloy windows and doors to name the distinction. Among them, 60 series and 40 series are the most widely used.
Choose the aluminum alloy windows and doors to see the thickness of the profile, regular manufacturers produce aluminum alloy window material thickness of 1.6mm or more.
Fourth, what are the aluminum alloy profiles for windows and doors
Materials can be divided into ordinary aluminum alloy windows and doors and broken bridge aluminum alloy windows and doors, aluminum alloy windows and doors profiles specifications are: 35 series (meaning that the width of the main frame of the aluminum alloy profile is 35mm, respectively) 38 series, 40 series, 60 series, 70 series, 90 series and so on.
Aluminum alloy windows and doors have a variety of prices, mainly to the profile for the brand, the thickness of the profile, the thickness of the glass to set.
Fifth, the specifications of aluminum alloy windows and doors profiles
1. Aluminum alloy windows and doors profiles specifications are: 35 series, 38 series, 40 series, 60 series, 70 series, 90 series and so on.
2. The so-called 35, 38 refers to the width of the main frame of aluminum alloy profiles are 35mm, 38mm.
3. Aluminum window and door profile specifications, mainly to the profile cross-section of the height of the size (used in aluminum alloy windows and doors said that the thickness of its door and window frame size) as a sign, and constitute the size series.
Aluminum alloy windows with the size series is relatively small, aluminum alloy doors with the size series is large. Aluminum windows and doors marked with the same size series, not necessarily aluminum windows and doors profiles cross-section shape and size are the same.
Profile production characteristics:
1. Varieties of specifications. Has reached more than 10, 000 kinds,are in production, in addition to a few special mills to produce specialized products, the vast majority of profile mills are in the multi-product, multi-specification production.
2. Large differences in cross-section shape. In the profile products, in addition to the square, round, flat steel section shape is simple and not much difference, most of the complex section profiles (such as I-beam, H-beam, Z-beam, channel steel, rails, etc.) is not only the section shape is complex, but also a large difference between each other, the hole design of these products and rolling production has its own specificity.
Six, aluminum alloy building windows and doors how to sell
To be based on the local daily price of the day ingot + processing fee/ton, the price of aluminum alloy profiles should be priced according to the surface treatment and processing of the profile you need. Different surface treatment prices are different, the aluminum ingot market fluctuates greatly, determining the price of aluminum alloy profiles for windows and doors.
Seven, aluminum alloy window and door profile thickness deviation
1.4mm aluminum alloy window profile thickness allowable deviation is ± 0.05mm. Aluminum alloy is the most widely used in industry, a class of non-ferrous metal structural materials, in aviation, aerospace, automotive, machinery manufacturing, shipbuilding and the chemical industry has been a large number of applications.
Aluminum alloy density is low, but the strength is relatively high, close to or more than high-quality steel, good plasticity, can be processed into a variety of profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, the amount of use of the next to steel. Some aluminum alloys can be heat-treated to obtain good mechanical properties, physical properties and corrosion resistance.
Eight, aluminum alloy windows and doors profile size
Aluminum alloy window and door profile specifications are mainly: 35 series, 38 series, 40 series, 60 series, 70 series, 90 series and so on. The so-called 35, 38, refers to the width of the main frame of aluminum alloy profiles are 35mm, 38mm . Sealed balcony usually used in the 70 series or 90 series, if less than 70, the degree of
solidity is difficult to guarantee.
Nine, how to identify the good and bad aluminum alloy doors and windows profiles?
The material of aluminum alloy is directly related to the quality of the product, which is very important. You can take a simple look, two pinches, three measurements and four scraping way to identify:
A look: look at the thickness of the profile and the flatness of the relevant groove, the thickness of a good profile should be more than 1.0mm, while the groove is flat.
Two pinch: hand test the weight and tensile and bending resistance of the profile.
Three measurements: with the aid of common tools, test the wall thickness of the profile and specific gravity.
Scratch: Scratch the surface of the profile with coins, nails and other slightly sharp objects. Good profiles will have shallow or even invisible wear marks.
