Q:There are provisions in the specification! Metal shutter doors and security doors are all special doors!

With metal doors and windows installed inspection lot, special door is fire, explosion, air defense doors and so on.

Q:I mean for double protection against leakage , will a wooden door or a metal one of the cabinet where this oven is placed cut off hazardous radiations.

microwaves cannot pass through metal at all. even tin foil. the door of the microwave, as you might notice, has a sheet of metal with a bunch if round holes in it. the holes are just small enough that the microwaves cannot pass through them. as for the wood it would depend on what size. i don't believe that the microwave would pass through a piece of wood thicker than 1/2 inch. microwaves only penetrate food about a half to one inch. they cook the food by exciting the water molecules in the food and causing internal friction. the friction then spreads throughout the food. the wood should be enough to stop the waves. if you want to perform a science experiment put a glass of water in a wooden box and microwave it. the wood might get slightly warm as there is some water in wood. but if the water does not heat up then you would have your answer.

Q:Home titanium magnesium alloy door is good or solid wood door good

That is, warm and beautiful with solid wood doors, alloy doors look good keep warm

Q:My house downstairs to open an aluminum doors and windows store, every day a lot of people. Now aluminum alloy doors and windows really so buy it?

Aluminum doors and windows in the price advantage, coupled with the upstream industry real estate continued hot, and now aluminum doors and windows is still better to do. But the premise or choose their own aluminum doors and windows. Such as Rolandi doors and windows, the times Hui industry doors and windows, Royal Yantian doors and windows, Parker Feifei doors and windows, home good windows and doors, etc., are very many people inquiry, great potential.

Q:its a double car garage, windows across the top. When we had it installed we didnt opt for the extra money to get an insulated one and boy are we sorry. Our previous garage door was wood, which never got hot to the touch so we had no idea how hot a metal one would get - the heat that thing radiates is incredible and its not even in direct sun

Yes, it's possible. Look on lines for tutorials since there are many options and techniques for doing it. Check out the options and go for the one that seems to work best for you.

Q:I just bought an 2009 4-Door Accord with dark grey polished metal color. Having the most difficult time deciding on which rims to get for my car. The following two links are the two I am considering. One is a 5-star and the other is a 7-spoke. Also, should I get a rim with the gun metal (dark Grey) finish, or polished aluminum? I don't like black or shiny Chrome rims---think they look stupid.

My personal Opinion would be the 5star because I have always been a sucker for a basic 5 star wheels, and the finish is killer, I personally would like to see the 5 Star,

Q:That is, the calculation of the box and the method of the fan, please write a careful point I was an apprentice would like to ask the teacher and do not want to ask the master please help out Thank you!

The general sliding window to pull out the width of the addition of a 2 is equal to the width of the fan, but generally minus 1-2 mm will be better

Q:Aluminum alloy doors and windows material thickness how to choose

Yi shield doors and windows to remind you, the thickness of the material generally refers to the wall thickness of the material, aluminum doors and windows of the national standard is 1.4mm or more, but the actual life, 1.0mm is to meet the needs of the owners, the choice of doors and windows material thickness is the most important Look at the needs of the owners themselves. If you need to sound insulation good, naturally choose some thick thickness will be better.

Q:i really cant find the asnwer someone help its for homework

Lowri the only doors that do this are fire doors And these have a quick release handle to open them No other door should lock by itself

Q:Aluminum alloy doors and windows broken bridge and what is the difference between ordinary materials

First: magnesium this thing is used for heat, since you first do the doors and windows should be considered is the performance of its thermal insulation, so as to reduce the heat exchange inside and outside your house, so as to achieve the purpose of energy conservation and environmental protection. Aluminum alloy thermal conductivity is less than half of the magnesium alloy, you should of course choose the authentic aluminum doors and windows. Second, you have to distinguish between the [magnesium titanium alloy] and [magnesium titanium alloy] the difference between the former main material is magnesium and titanium, especially titanium, the cost is very expensive, and more for precision instruments and aviation and other fields. While the latter is in the main material inside the aluminum alloy with a trace of magnesium and titanium, the price difference with the former thousands of miles. Moreover, the aluminum alloy itself can not be 100% pure aluminum to create itself contains trace of other elements, including magnesium and titanium. With the [titanium magnesium alloy] to make home doors and windows like Beckham to go to the square aunt playing shuttlecock game, is simply extremely shameless waste. Third: the current market appears magnesium titanium alloy doors and windows without exception, are the business of the trick only, the word of the word game misleading consumers, [poor mm cents to thousands of miles]. Fourth, it is recommended that you can use 【broken bridge】 series of aluminum doors and windows, both high strength and durable aluminum, while the middle of the special thermal bridge and significantly reduce the thermal conductivity of aluminum alloy, thus making up the alloy The material was originally easy to heat the shortcomings. Better play a heat preservation effect. Of course the price is more expensive than the ordinary aluminum alloy.
