Q:Aluminum alloy doors and windows materials only silver and brown it?

Aluminum alloy doors and windows materials There are a variety of colors, not just silver or brown, but these two colors used the most.Aluminum alloy doors and windows of the color of the formation of two ways, one is the aluminum oxidation method. Aluminum material surface is easy to naturally A layer of oxide film, the oxide film is relatively dense, hard, can play to protect their own role.To take the chemical method formed by the oxide film, known as the anodic oxide film, relative to the natural formation of the oxide film, the oxide film The thickness of the relatively large, the protection of aluminum alloy material is better, but also can control the formation of a variety of different colors, such as silver, brown series, gold, red, blue, green, etc., not only has a protective effect, and With silver and brown look stable, generous, more generally accepted, custom made aluminum alloy doors and windows of the profiles are processed into these two colors, while the other colors, in other aluminum products are more common in the doors and windows of materials The main reason is because the general profile are relatively long (4 ~ 6m), the surface treatment, the need for a large oxidation tank, the oxidation of the liquid The demand is also a lot, the cost can be imagined, if there is no large number of processing orders demand, change the color of the feasibility is very small.For mass production, the use of aluminum oxide surface treatment of doors and windows materials, the cost is relatively low, Is conducive to the extensive application of aluminum alloy doors and windows materials.

Q:I have a metal security door and frame that has come out of square. The top of the door is rubbing against the top of the frame, and it is very difficult to push close.If this was a wood door, Id probably shave it. Ive never dealt with this in a metal door. Whats the best way to fix it?Thank you!

Go to door manufacturer

Q:How best to paint a metal screen door. spray paint? What type and brand ?

You need to wash it off first. Then use Rustolium Industrial Spray Paint.

Q:Please use the professional point of the physical language to answer, in detail, thank you!

Winter weather is dry, wearing a lot of charge in the friction will accumulate, resulting in electromotive force, which is generally said that static electricity, metal objects will be triggered when the discharge phenomenon, people wearing static electricity can be higher, but the current will not be great , So will feel the shock, the general will not occur malignant consequences of chemical fiber clothing generated by the electrostatic voltage will be greater,

Q:How do I repair stripped hinge screw holes in metal clad entrance door?

You need to plane the door down. If you don't have a planer, you can try 2 things. First try taking the door off. Remove the hinges and chisel the notch/mortise for the hinge an 1/8 or so deeper and remount the hinges and reset the door and see if that fixes it. Important: get new screws and make sure they are longer then what you took out. I would go as long as 1 1/2. You should also replace the ones in the frame with longer ones to. Use a 2 1/2-3 screw in one of the holes of each hinge in the frame. This is what should be done when a door is initially installed. Those longer screws are called set screws. If you are still rubbing and you don't have a planer, but do have a circular saw, you can clamp a straight edge to the door as a guide and cut the door. If you do cut it or plane it, do it on the hinge side. I think if you try the deeper notches on the door, your door will open easier for you. If it improves it but it still is a little snug, try putting some paint stripper in the inside of the frame and remove the multiple layers of paint, then sand it and repaint it. Just sanding the frame as you suggested may work, but if it's a tight as it sounds, you would have allot to sand. 80 yrs old, I guess it's probably got at least 6 coats of paint. By the way your toothpick thing is a trick if you need to fill a hole and put a screw in close to that original hole. What you did, didn't really help. it might have compounded the problem. I hope this helps you some and good luck

Q:In the dry winter, you may have had this experience, when you have a carpeted walkway came to the door of the room, hand in contact with the metal door of the moment

It is the phenomenon of electrostatic discharge, human clothing in the friction so that the local electrical uneven, stripped of course, will discharge and see the spark heard the sound. Door handles and people with your body with dissimilar charge can easily become your discharge object. Friction of the friction of the amber with energy to attract hair, because the hair is not charged, the discharge is naturally not obvious.

Q:Shuo steel doors and windows and aluminum doors and windows have any advantages and disadvantages

There are no advantages and appearance of the aluminum alloy, of course, the rural stalls which are very low prices of aluminum alloy when not to mention, the price of steel I do not understand, but the aluminum alloy is: Material 1.4mm, glass 6mm steel, then push and pull will go to 250 to 280, then open the words will go to more than 300, the price is basically the cost of regular processing production

Q:Slide and what is the difference between the box ah (understand the aluminum doors and windows of the master answer)

Slip is on the track, the box is the frame material

Q:Self-employed, small facade. The Production of aluminum doors and windows, Need a production license? ////

Processing of aluminum alloy is not in the "industrial product catalog", so no need for a production license.

Q:Aluminum alloy doors and windows frosted surface and smooth which is good

Pros and cons! Such as the texture of the mute better but dirty is not easy to clean, some low-end products will have a larger color (due to the temperature caused by spraying). Smooth, but easy to clean but easy to produce scratches. Color saturation glossy than the hemp is much better. As the light linen powder raw materials and technology on the difference is not, so the surface fade and adhesion on the basic no difference. Please consider the actual situation as appropriate
