What is the national standard for the deformation of plastic steel windows

This is based on GB T8814-2004.

If I remember correctly, the main profile control is bent no more than 1mm meters, and the secondary profiles are no more than 2mm meters.

In any case, it is impossible to pass a drum of three centimeters.

It should be a window frame, up to 5 mm, and if it is a fan warpage, it should be controlled within 2 mm.

Let's take a closer look at this information

I don't know if you are talking about the window frame or the sash, the national standard of the frame is the allowable error of 3mm, the national standard is the national standard acceptance standard for plastic steel doors and windows, it is also 3mm and can not affect the normal use, if your plastic steel window is defective, it should be within the scope of the warranty, you can ask for replacement.

The project requires a warranty of 2 years, with a warranty).

That's pure nonsense. The plastic steel window is deformed, how can it be said that it is a national standard regulation? That national standard stipulates that plastic steel windows can be deformed?

The profile of the plastic steel window has a shell curve standard, but the door and window have not heard of a permissible deformation, your problem is a pure quality problem, and it is irresponsible to speak.

You asked him to provide the national standard, and find out which clause in the standard states that the plastic steel window is allowed to deform 3 cm?

Not true! This is the case with cheap profiles! A good profile, if the window type is too large, there will be different degrees of downward deformation! Everything else is a profile problem!

First, the implementation of standards:

1. "PVC Plastic Shed Source Material Window" sells JG T3018-94.

2. "Detection Method for Mechanical Force of Building Exterior Windows" GB9158-88.

3. "Classification and Testing Methods for Wind Pressure Resistance of Building Exterior Windows" GB T7106-2002.

4. "Classification and Testing Methods for Air Tightness Performance of Building Exterior Windows" GB T7107-2002.

5. "Classification and Testing Methods for Watertight Performance of Building Exterior Windows" GB T7108-2002.

Second, the test content:

1. Dimensional deviation.

2. Opening force.

3. Wind pressure resistance.

4. Air tightness.

5. Water tightness.

1.According to the relevant provisions of the national standard GB T8814-2004, the outer side of the profile is co-extruded, the inner side is covered with film (imported), the color and style are sealed by the slag and the party before bidding, and the casement window and casement door are made of 66C or 65B series profiles. The minimum measured wall thickness of the stressed part of the cross-section should not be less than but not less than 5 cavities.

2.The sash and frame of plastic steel doors and windows should be made of 450 corners, and other connection methods are strictly prohibited;

3.The casement window frame and sash are made of thick U-shaped reinforced steel, and the casement door leaf is made of thick U-shaped reinforced steel. The mullion is reinforced with 2mm square tubes.

4.Reinforced steel is added in the reinforced steel cavity of PVC profile, and the matching gap between reinforced steel and reinforced steel cavity should be 1, so as to ensure that the reinforced steel is easy to install, and can be restored to its original state after being shielded by wind pressure. When the reinforced steel is processed, the dimensional tolerance is .

5.The reinforced steel should be consistent with the size of the inner cavity of the profile, the matching gap between the reinforced steel and the inner cavity of the profile should be 1mm on each side, the distance between the end of the reinforced steel and the weld should not be greater than 5mm, and the welding of the end should not be affected, and only one reinforced steel is allowed to be used for each profile. The fasteners used to fix each reinforced steel shall not be less than 3, and the spacing shall not be greater than 300mm, arranged in two rows of dislocation, and the maximum distance between the fasteners and the weld of the profile shall not be greater than 20mm, and the reinforced steel shall not be loosened after fixation.

6.At the weld of the profile that needs to be welded, the reinforced steel should be as long as possible close to the weld, and for the 45 weld, the section steel should also be cut into 45.

7.During the period from the completion of the production in the factory to the completion and acceptance of the project, all exposed surfaces of the profile indoor and outdoor should be protected by protective film or paper tape; The protective film or paper tape shall be removed by the winning bidder after receiving the notice of the tendering unit before the completion and acceptance.

8.The base material of plastic steel door and window profiles should meet: GB T8814 2004 "Doors and Windows Unplasticized Polyvinyl Chloride (PVC-U) Profile", JG T140 2005 "Unplasticized Polyvinyl Chloride (PVC-U) Plastic Windows", JG T180 2005 "Unplasticized Polyvinyl Chloride (PVC-U) Plastic Doors", etc.; The wall thickness inspection of the profile is only allowed to meet the requirements of the specification class A, otherwise it will be regarded as unqualified.

Plastic steel doors and windows are a type of doors and windows that have the characteristics of corrosion resistance and weather resistance, after using the plastic steel doors and windows of the potato wheel for a period of time, some plastic steel doors and windows may be deformed, what is the reason for the deformation of plastic steel doors and windows? Today, PCHOUSE will answer them for you one by one.

1. The deformation of plastic steel doors and windows may be caused by the material of plastic steel doors and windows themselves, and the wall thickness of plastic steel is relatively thin, if the cavity design of plastic steel doors and windows is unreasonable, it will cause the profile material of plastic steel doors and windows to be soft, resulting in deformation.

2. The steel lining of plastic steel doors and windows is not fastened with the profile in accordance with the standard, which may also lead to the deformation of plastic steel doors and windows, the steel lining of plastic steel doors and windows is not tightly combined with the profile, and it is necessary to use screws to fasten the profile into one, and fix no less than 3 screws for each steel lining, and the spacing is not more than 300mm. The distance from both ends of the profile is not more than 100mm.

3. The improper connection method between the plastic steel doors and windows and the wall, and the soft materials are not embedded around the frame, and the formation of "expansion joints" will also lead to the deformation of the plastic steel doors and windows.
