Q:why a metal door should not be built to fit tightly to a frame of a door in a hot weather region?

metal expands in the heat and contracts in the cold if it fits too tight when it gets hot you wont be able to shut the door

Q:My home aluminum doors and windows have some small gaps, one to the winter from the cracks to the indoor ventilation, quite cold, please teach me some tips to make up for these gaps. (Not too complicated, but also to open the window next year) Thank you!

If it is splicing gap, glue can be. If the sliding window to see if there is two cross-section of the wind fast, if not can consult a professional, with special wind fast.

Q:cause the keys to my metal slide-door keeps bending and breaking.

Then the problem is not a weak key. The problem is in the lock itself. If your key is breaking then the lock or door needs to be serviced. Call a Locksmith! ;-)

Q:What is the difference between a composite door and an aluminum alloy door?

Solid wood composite door The door of the solid wood composite door is mostly made of pine, fir or imported filler material, and the external density board and solid wood veneer are made by high temperature hot pressing and sealed with solid wood lines.Generally advanced solid wood composite door, The door is mostly high-quality white pine, the surface is solid wood veneer.Because the white pine density is small, light weight, and easier to control the moisture content, so the finished door weight are lighter, not easy to deformation, cracking. In addition, solid wood composite doors But also with insulation, impact resistance, flame retardant and other characteristics, and the sound effect is basically the same with solid wood doors. Steel and wood composite doors The door is made of steel plate after a molding process, and then with the solid wood frame and within the filler compound is not easy to deformation, but also pest control; moderate steel doors afraid of scratches, once scratched, make up the paint looks not complete. Resistant to wear. Aluminum alloy door is made of aluminum alloy, waterproof, solid wood composite door steel and wood composite doors used in the gate and the room, aluminum doors used in the balcony door

Q:Just a normal sort of door -- painted to prevent rusting. Really need help, thanks!

Probably steel or aluminum. No wrought iron is not commonly used. If it is heavy, it is steel; if it is light, it is aluminum.

Q:Aluminum alloy doors and windows where the best sales?

In fact, the general large and medium-sized cities, need to use large quantities of aluminum doors and windows and curtain walls, aluminum doors and windows can be said that do not have any area, as long as the flow of relatively concentrated large and medium-sized cities, will continue to set up and update real estate, (Of course, although not absolute, but for the non-use of the building, life only in the tent living in Mongolia with the package, we do not have to spend too much energy) now the rural market can also be developed for the like , But after all, do brand products, is unable to meet the rural market on the "cheap" pursuit, so that, as for the aluminum alloy doors and windows where the best sales, it is necessary to vary from place to place, because the brand grade varies Wait......

Q:Metal things may exist static ah, we usually touch a metal thing in winter may have static electricity, Party A now ask this question, ask how to consider the doors and windows to remove static electricity? I do not know ye get it

How could the metal take the static back to his head is not stuck or do not want me to use a hammer to help him repair

Q:Open a small aluminum alloy doors and windows factory need?

Site, equipment, personnel The site includes processing production, parking. Equipment requires a double saw, one end milling saw, two sets of angle machine. Double-headed saw is the frame of the fan for cutting processing, end milling saw is processing in the stakes, the group angle machine is for the frame assembly. Equipped with two sets of such workshop processing equipment without free, can be more reasonable to the equipment applied. Personnel, since it is small, it is recommended not to install the staff, only with the processing of production staff, on-site installation outsourcing out. In addition, it is not recommended to increase the space glass synthesis workshop, on the one hand to increase the site area, increase staffing, but also increase the cost of investment, and the beginning of the small scale as much as possible to save money to the operation of the project to use. Glass is best from the glass factory procurement, and then directly to the scene, if you set the glass products workshop, to the finished glass transport to the site, which has increased the damage of the link (the glass is fragile) Precautions: 1, equipment, if the funds are not particularly adequate to consider buying domestic brands, in fact, many domestic brands are also good quality; 2, personnel, the best selection of large windows and doors out of the experienced workers, this will be the greatest reduction in the beginning There are too many immeasurable losses. It may be that these people are more expensive to use, but can keep your project progress and computable engineering profits secure. 3, at the beginning of the project as much as possible not seeking stability. Hope this helps you.

Q:Titanium magnesium alloy doors and doors compared to where the advantages

Titanium-magnesium alloy doors and doors compared to the obvious moisture-proof properties, composition stability, anti-aging, no deformation, sound effects better than the wooden door

Q:I mean when weather is dry, and I am about to enter a store, I can see it coming! that huge electrical charge that was being built inside my body! I become 100% sure I will be shocked as soon as I touches that metal handle, so I approach the handle with my hands, and quickly back up my hand again before it touches! then try to catch the handle again then back it up again! like 3 times back and forth in one second till I have the courage to touch it and get my lovely shock! and open the door! Am I the only one who do this? are you guys touches it with confidence even if you get shocked? are you brave enough to not care about that 2000 volt charge? I know it is not fetal thing, and I read all things about electrostatic and how to avoid it and all that bla bla bla.. but in reality, some days, you cant escape your fate!!

I wind up getting a little gun-shy around door handles in the winter time too. I'm not as bad as that, though. Just try to touch the handle with the back of your wrist first. It will get rid of the charge that you've built up, and you don't have a high density of pain receptors there compared to your fingertips, so it won't hurt nearly as much.
