Now there are many kinds of doors and windows that are renovated. Conch windows are one of them. It not only has its own unique advantages, but also has a good thermal insulation effect and a relatively high strength. We may not be familiar with conch window, the following small series will introduce you to the relevant knowledge of conch windows .
First, conch window
For Conch-steel doors and windows, its heat transfer performance is low, which is l/357 for steel and 1/250 for aluminum. It is foreseeable that it has a good heat insulation effect and is particularly suitable for buildings with heating and air conditioning equipment. According to surveys and comparisons by relevant departments, the use of conch doors and windows is 4-5 degrees warmer than the use of ordinary doors and windows, and double-glazing is more effective in northern areas. 
Second, conch plastic window type
1, fixed window
Fixed windows are very common windows on the market today. From the outside, it is not a lot of style, but from a practical point of view, it is better to fix the windows, at least for a relatively long period of use.
2, hanging window
The top-hung window is almost unusable in general home decoration. It is basically used in large medical institutions and shopping malls. In terms of price, because conch steel is a brand-name product, the price is relatively expensive, but the quality of the product is still relatively safe. 
3, in the hanging window
Compared to the hanging window is also a relatively common window, for those who want to decorate, if you want to pursue good results in the home improvement, hanging in the window is a good choice. At the price point, because the design and manufacturing of the hanging window is difficult, the price will also fluctuate.
4, under the hanging window
The use of the under-hung window is very wide, and is generally used by every family. In addition to considering the brand before the purchase of the next hanging window, it is also necessary to strictly control the style and quality of the product, so that there is no need to worry about quality issues in later use. 
5, conch plastic steel doors and windows - vertical turning window
In the appearance of styling on the vertical window and other types of comparison are relatively special, if you want to pursue better visual effects, Lifan window is a good choice. Whether it is in style or in the whole, it is more fashionable and certainly more expensive in terms of price. 
Summary: The above is the relevant information about Conch Window , and everyone has a lot of understanding about Conch Window! If you need a good door and window to use at home, try conch doors and windows. For more information on Conch Window, please continue to pay attention to this site information.
Conch Plastic Window
Cold Drawn Steel Bar is produced by hot rolled steel bar or wire rod to get smooth surface, more precision size, higher mechanical properties, which improves machining characteristics. It can also get various sections and sizes. So cold drawn steel bar is a better choice for machining users.
According to different steel grade, the production line is usually different. The Basic production line is as below:
For high carbon steel or alloy steel bars, to avoid the cracks in inner or surface, the bars are usually required to be annealed before cold drawing.
To get different mechanical properties or hardness depending on final usage, the cold drawn bars will also be heat treated such as annealed, normalized or quenched and tempered(Q&T).
For CNC machines usage, to get much more precision sizes or much more better surface roughness for chrome plating, the cold drawn steel bars can also be centerless ground or polished.
We have more advantages on producing cold drawn steel bars:
1) Big stocks of hot rolled round bars or wire rods as raw materials
2) Wide range of cold drawn steel bar sizes: from 10mm to 150mm
3) Different cold drawing medias powder or oil to get different surface
4) Straightening machines to get better straightness up to 0.5mm/m
5) Grinding and polishing machines to get better roughness upto 0.4um
6) Heat treating furnaces to adjust the mechanical properties
7) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.
8) Multiple packages to avoid broken packages and anti-rusty
