Specification for steel profiles
- Before 50, did not use 40 or 38, 10 years ago I have done spliced steel, and now who is willing to splicing ah. But really want to splice, and now have steel can also be spliced.s
What is the amount of plastic profiles
- The size of the sliding window lap affects the sealing of the window, safety, installation, daily use and so on. (12mm-8mm = 12mm), the gap between the fan and the ribs of the box (ie, the slide) is 12mm (20mm-8mm = 12mm). ), This gap for windows to install and pick up. When installing the window, the sash and bottom frame are only 4mm at the top of the ribs. Due to the size deviation of the window frame and sash, the straightness deviation of the window frame installation and the height change of the pulley used will change the actual overlap and installation gap of the frame fan. When the amount of overlap between the fan and the upper frame increases, the installation gap decreases, and the window fan is hard to be installed, and the frictional force of the window and the upper seal block increases, resulting in the opening of the sash; Sealing performance decreased, lap volume is too small, but also increase the risk of sliding window off.s
The development of steel profiles
- From white to color: color profiles change the steel doors and windows in the past monotonous white, with the building as a whole with the perfect color. Color profiles market share rose rapidly, especially in some high-end residential area widely used.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
How to identify the installation of plastic or plastic
- Through the cutting, welding, etc. made of doors and windows of the frame fan, equipped with sealing tape, tops, hardware and other accessories made of doors and windows, in order to enhance the rigidity of the profile, more than a certain length of the cavity need to add reinforced steel (steel Lining), this kind of doors and windows called plastic doors and windows.s
How many meters of a conch plastic steel profile
- You ask what is the use, to do is to open the window or push and pull, and generally 6 meters large amount of work can go to the factory to ask them how long pulls

Plastic doors and windows profiles
- The inherent quality of the profile and its reasonable structural design are the prerequisites for the manufacture of high-performance plastic windows. First of all, there must be good formula and high-quality raw materials and advanced production technology to ensure the quality of profiles. In addition from the structure of the profile of a single cavity and multi-cavity PVC plastic profiles, the cavity can be designed ribs, ribs, boss, etc., can be divided into two cavities cavity, three chamber or multi cavity, Can be better from the role of thermal insulation, on the other hand can make the cavity have different purposes, and some used to fix the rigidity of the steel lining, and some used to set the drainage chamber, and some internal ribs can be prevented Profile deformation, the inner ribs can improve the rigidity of the profile, increase the inertia moment of profiles, and improve the impact resistance of profiles.s
