Hope you can understand.

Q: Do you have a plastic door?: Plastic steel doors and windows of the main raw material is polyethylene resin, in the molding before the need to add titanium dioxide, UV absorbers, processing modifiers, impact modifiers, internal and external lubricants and fillers. As the basic structure of the profile is PVC resin, so there are some characteristics: 1. Machinability In the molten state, the plastic has a relatively high mobility, so through the mold can form a precise cross-section structure, in order to achieve the window should have the functional needs. And can form a split chamber to improve the window of the insulation, noise, drainage function, can avoid the enhanced steel corrosion.

Q: Outdoor aluminum alloy or steel doors?: Overall steel good point, because the plastic steel sealing performance slightly better.

Q: What is the difference between steel-plastic doors and steel doors?: The two components are different, steel-plastic doors better than steel doors. Both have their own characteristics. Steel is the main component of PVC-U extrusion molding of doors and windows materials, which is a building materials plastics. The full name of steel and plastic is a total of plastic and plastic, is the use of PVC crust micro-foam, and special-shaped steel lining co-extrusion method, and then by high-strength steel angle components into a door and window products. This high-tech patent products available, successfully overcome the ordinary steel doors and windows exist wind pressure performance, can not be high-rise building problems. At the same time also played the advantages of two kinds of steel materials - plastic micro-foam technology, excellent insulation, insulation, and high-strength type of special-shaped steel. Steel plastic materials also have no deformation, long life, environmental protection and other advantages.

Q: Plastic door switch door when the door is getting bigger and bigger how to do? I was renovated in December last year, the installation of steel doors, the use of six months are better, but nearly half a year, every time the switch door, door hinge (as if) will have a very loud squeak sound. Especially at night, it is harsh. Which is any skill to teach me? Thank you Oiling will bring a troubles: more likely to fouling, leading to the impact of beauty. I would like to know whether this sound represents a fault phenomenon?: This is a common problem. Hinges lack rust-free lubrication, affecting the appearance, will issue a squeak sound, affect the rest. Meikailong and other well-known hinge brand with tiger hotolube or Krupp's hinge hinge grease, colorless and transparent, good adhesion, good durability. Panther has 130 grams of tube packaging, but also for sliding doors and so on. Grease directly applied to the hinge gap, will slowly penetrate into the hinge inside. The maintenance period is four to six months. Should not use the oil or ordinary butter, easy to lose or low temperature freeze, there will be harmful smell volatilize. Vegetable oil will soon rancid produce odor, loss of lubrication.

Q: Home steel doors and windows original developers to install a single layer of glass, now want to transform into double glass. Find a production unit asked the next, said only the original single glass to cancel (waste), and then replaced by their custom double-layer insulating glass. Price of 260 square meters. Is this expensive expensive? Chongqing area. Is there a cost-effective production unit recommended?: Hello there!

In the glass of your glass to be removed to get the processing place to do a few days to do a pair of glass (this time is not good to say) that your home window will have a few days without glass, and the expression is not very good, nor Know not help to help you. The price of some of the high number of mantissa almost, I was in OKorder do not know your side of the market is feeling too expensive.

Q: What is the difference between steel doors and windows and broken doors and windows: Plastic doors and windows belong to the previous generation of products, the main material used plastic materials, glass for the double glass; broken bridge window in recent years, emerging profiles, to solve the plastic doors and windows strength, stiffness is not enough, and traditional aluminum doors and windows insulation effect is poor The problem is the master of the two. At present, steel doors and windows are gradually out of the stage of history, only in low - cost housing, rural areas, the only advantage is cheap, and with the passage of time prone to fade, deformation. Many of the old district are also gradually replaced in the new broken bridge aluminum doors and windows.
