Q: See you answer to someone else on the aluminum alloy doors and windows of the formula, write very detailed, I was just beginning to do this industry, there are many problems Imagine you ask, hope a lot of guidance, brother Thank you!: Aluminum alloy doors and windows production process The line to find the rules → door and window hole processing → door and window openings buried iron pieces → aluminum alloy doors and windows unpacking inspection → according to the drawings number to the installation site → check the aluminum alloy protective film → aluminum doors and windows installation → door window around the caulk, fill Insulation material → cleaning → installation of hardware accessories → installation of doors and windows seal → quality inspection → yarn fan installation Shell line to find the rules: at the highest level to find the door window edge, with a large line of the door line will be cited under the line, and in each layer of the window at the crossed mark, the individual should not straight mouth should be chiseled. High-rise buildings can be used to find the vertical line of theodolite. The horizontal position of the door and window should be based on the floor + 1250px horizontal line, upside down, the amount of the window under the skin elevation, straight line, each floor under the skin (if the same height) should be on the same level. Wall thickness direction of the installation location: According to the external wall sample and the width of the sill plate to determine the direction of the installation of aluminum doors and windows in the direction of wall thickness; if the wall thickness deviation, in principle, should be the same room window plate exposed size Shall prevail, the windowsill plate should be inserted into the window of aluminum alloy window 5mm is appropriate. Installation of aluminum alloy window water: according to the design requirements will be fixed on the aluminum alloy window, should ensure that the installation location is correct and firm.

Q: Bathroom kitchen first tile or first aluminum alloy door? anxious!: Aluminum alloy door with door sets and no door sets of two. With the door to the first paste a good brick, and then install the door, the door is above the brick. Not with the door can be in no order, because the door with the brick just like alignment.

Q: Aluminum alloy doors and windows made with what glue: Aluminum alloy doors and windows made without glue, with connectors.

Q: I would like to ask the general home titanium alloy door a door how many square meters?: General home furnishing titanium alloy doors are about 2 meters in height, width is about 0.8 meters, so a door is about 1.6 square meters. Two sliding doors are generally wider, an area of about 2 square meters. Because the construction of the door after the completion of the size of the door is not very standard, the width and height of the door is often not exactly the same, that is, the same house in different rooms of the door will be wide and narrow, high and low, The Therefore, the specific customization should be measured one by one.

Q: The door is wooden, but the door frame is metal (I found out when the screw wouldnt go in no matter how I hammered it). Is there a way to install a hasp to put padlock on? (Are there screw drivers for metal surfaces?) Or is there any other way to have the door locked without having to installing a cylinder lock?: You need to drill a hole first with a metal twist drill bit. Get a drill bit that is the same size as the screw shank (the solid part below the threads - the hole must be smaller than the diameter of the threads, so there is material for the threads to bite into), mark the location of the holes for the hasp on the frame, and drill the holes to the depth of the screws. Then attach the hasp.

Q: I am going to learn to do aluminum alloy doors and windows, would like to ask this industry to make money? I learned to open their own facade, please do this line of people to answer,: Do too many people are familiar with the road income is relatively unstable

Q: Aluminum alloy doors and windows surface oxidation how to deal with?: The chemical nature of the aluminum element itself is very lively However, the aluminum alloy surface will form a layer of dense aluminum oxide film Thereby preventing the internal aluminum from being continuously oxidized The surface oxidation of the aluminum alloy is for the thickening of the aluminum oxide film Enhance the corrosion resistance and abrasion resistance of aluminum alloy products.

Q: a metal entrance door swings freely in the winter, but when the weather turns warm, the door sticks and seems too big for the door frame. Using your knowledge of the particle theory, explain what is happening.: The door is made of metal and the frame is probably made of wood. Metal expands more than does wood when it is warm, so the metal door actually gets bigger and tightens up in the frame. From a particle theory perspective, the metal door expands more than does the wooded frame because its particles are closer together and pushes other particles more as they move or vibrate more and faster as they get warm.

Q: Bathroom doors or titanium magnesium alloy door is better?: Titanium magnesium alloy door.

Q: Summer that it melted the window insert in the steel door so it doesnt fit tightly. What to do now? Also is it better to paint the steel door a darker shade? Its now white and if so what type of paint to use that can take the heat.: switch to a solid door, those inserts are cheap plastic trash and they come loose and leak from old age not just heat. white is the coolest color and any other color will make it hotter. the bottom of the door has room so adjust it to leave a gap for fresh air to get in and you can peel the weather stripping off of the door at the top so it lets some of the heat out. the best solution is to tint the glass with a reflective (mirror look) light smoke window tint so its not dark but it blocks out a lot of the heat
