Q:Custom steel doors how much money a square: Custom steel doors made of single-layer steel 140 yuan a square, double-layer steel 160 square. Of course, aluminum is good, no deformation, no yellowing, do not fall off.

Q:My house new house ready to install steel doors do not know how good to give you advice: Advantages and disadvantages of steel doors and windows Advantages: Not only beautiful and durable, and the lowest thermal conductivity. In terms of energy saving is far better than wooden windows, iron windows and aluminum windows, is the most effective means of sealing. Ordinary steel prices affordable, economical and practical. High-grade plastic window insulation, anti-aging appearance is not easy to deformation. Now most of the buildings have been popular, the use of large, wide range of use, because steel windows do not use metal, the state also recommended. Disadvantages: Sealing, safety, anti-theft and ventilation quality is not satisfactory. The reason is the lack of supporting the use of high-quality stainless steel hardware, resulting in the current high-grade profiles supporting low-grade hardware dissonant state, and plastic (PVC) can not be degraded, waste plastic windows difficult to deal with environmental protection. There is a gap easy to rust, slightly worse sound insulation, ordinary plastic windows easy to deformation, such as high-grade imports of expensive, thousands of dollars per square meter.

Q:Plastic doors are plastic doors or metal doors?: Manufacturing process, wood door finished small.

Q:Plastic steel door titanium door which is good: 1, steel doors Advantages: (1) plastic steel door material with fire, no spontaneous combustion, no combustion, self-extinguishing. (2) thermal conductivity than wood, metal is much lower; insulation effect is much better than aluminum. (3) between -30 ℃ to -70 ℃, the sun, rain, dry, humid environment, no deformation, no discoloration, not brittle, but also acid and alkali drugs and waste salt erosion, , Cement, glue effect. (4) well-designed door structure with drainage, seams tight, can completely separate the rain, the sound is less than 20 UP. (5) the use of cleaning agents after cleaning as bright, the service life of up to 30 years or more. 2, plastic steel door Disadvantages: Plastic doors can only open one-way, the switch is not convenient, easy to deformation. 3, titanium door advantages: (1) high strength, good rigidity, light weight. (2) the use of temperature than aluminum alloy several hundred degrees, at moderate temperatures can still maintain the required strength. (3) titanium alloy in the humid atmosphere and sea water medium work, its corrosion resistance is much better than stainless steel; pitting, acid corrosion, stress corrosion resistance is particularly strong; alkali, chloride, chlorine organic products, Nitric acid, sulfuric acid, etc. have excellent corrosion resistance. But the titanium has a reducing oxygen and chromium salt medium corrosion resistance is poor. (4) titanium alloy at low temperature and ultra-low temperature, can still maintain its mechanical properties. 4, titanium door defects: The main limitation of titanium and titanium alloys is poor chemical reactivity at high temperatures with other materials. This property forces the titanium alloy to be different from the conventional refining, melting and casting techniques, and even often causes damage to the mold; as a result, the price of the titanium alloy becomes very expensive

Q:How much money to do a plastic steel door: By area, about 280 yuan / ㎡ or so.

Q:Please answer directly, thank you: This door should be calculated according to one, the basic standard toilet door in 1.5 square meters. Folded into square meters should be about 180 yuan. The identification mark is certainly yes, generally at the top of the door (lock position).
