What is the amount of plastic profiles
- Plastic window frame and sash with lap way to seal, fan and the box part of the overlap called the amount of overlap. The industry standard does not specify the amount of lap. For the flat window, lap is generally between 8 ~ 10mm. If the conditions permit, the amount of lap as much as possible to choose a larger, so that in the installation and use, even if the frame fan overlap position slightly dislocation, but also to ensure that the seal between the frame fan. Using different hardware, but also affect the amount of overlap factors. If the use of ordinary handle, frame fan lap can choose a larger, if the use of transmission handle, frame between the need for a certain gap between the installation of the drive, so the amount of lap would have to be smaller, otherwise, installed on the fan Of the transmission is easy to touch the window frame, affecting the sash switch. Therefore, even with the same profile, the lap should also be determined separately.s
Bathroom plastic door with what material to do
- Glass fiber reinforced plastic (FRP) doors and windows
1) abroad to alkali-free glass fiber reinforced, the product surface finish is better, no need to deal with the system can be used directly to the window. Domestic self-developed glass fiber reinforced plastic doors and windows profiles generally with alkali glass fiber reinforced, the surface of the profile after grinding, available electrostatic powder coating, surface coating and other technical processes, access to a variety of colors or texture of the decorative effect.
2) Do not use high-alkali glass fiber made of profiles.
3) FRP doors and windows profiles have a high longitudinal strength, under normal circumstances, you can not enhance the steel. But the doors and windows size is too large or high wind pressure requirements, should be based on the use of requirements to determine the enhanced approach. The transverse strength of the profile is low. Fiberglass doors and windows frame for the assembly of the turret, the joints need to use sealant seal to prevent leakage of the gap.s
What is the steel profile?
- The profile is still visible when the window is still visibles
The state of high-rise residential building doors and windows materials are not allowed to use steel profiles are expressly provided?
- Plastic can not be used mainly to see its ability to withstand wind pressure can not meet the requirements, and the state did not force the request. At present, only Qinghai is limited to plastic steel, it is because the UV is relatively strong in Qinghai, steel weather resistance is not good aluminum. In fact, as early as ten years ago, steel doors and windows can be used in the tall buildings in Xiamen, indicating the use of absolutely no problem, provided that your doors and windows must be reasonable design, through the local fifty years once the wind. But also in the doors and windows production and installation process to comply with the specification.s
Plastic steel window profile specifications models which
- Plastic doors and windows are made of polyvinyl chloride (PolyVinyl Chloride, often referred to as PVC) resin as the main raw material, plus a certain percentage of stabilizers, colorants, fillers, UV absorbers, etc., by extrusion molding, and then Through the cutting, welding or screw way made of doors and windows frame fan, equipped with sealing tape, tops, hardware, etc., at the same time to enhance the rigidity of the profile, more than a certain length of the cavity needs to fill the steel lining Tendons), so made of portal windows, called steel doors and windows.s
It is good for aluminum alloy
- Aluminum alloy high temperature, non-flammable; is a good conductor, lightning can be anti-static; recyclable, environmentally friendly. Plastic is not high temperature, combustion; is the insulator, but need anti-static; degradation is slow, can not be recycled, slow combustion will release toxic gases, environmental impact.s
What is the material of steel
- Plastic profiles are used for the production of doors and windows with PVC profiles, as early as the late 1950s has been in Germany, China began in 1983 from the beginning of the 20th century, the late 90s began universal application. Because simply use PVC profiles processing doors and windows strength is not enough, usually in the cavity to add steel to enhance the stability of doors and windows, so the profile of the steel interior made of plastic doors and windows are often called steel doors and windows. With the extensive use of steel doors and windows, PVC profiles for the production of steel doors and windows are commonly known as steel profiles.s
What is the meaning of steel profiles 80?
- The so-called 88,80,60, refers to the bottom of the profile width. The unit is millimeter. The profile manufacturers have these specifications are refers to the bottom of the width is the same, but different manufacturers of profile height is not exactly the sames
