Materiallarni ko'rib chiqing. Yuqori{0}}sifatli alyuminiy qotishma eshik va derazalar uchun alyuminiy profillar, qalinligi, mustahkamligi va oksidi plyonkasi tegishli milliy standartlarga mos kelishi kerak. Devor qalinligi 2,0 mm dan yuqori bo'lishi kerak, kuchlanish quvvati kvadrat millimetr uchun 157 Nyutonga, rentabellik kuchi kvadrat millimetrga 108 Nyutonga va oksid plyonkasi qalinligi 10 mikronga yetishi kerak. Agar yuqoridagi standartlar bajarilmasa, alyuminiy qotishma eshiklari va derazalari past sifatga ega va ulardan foydalanish mumkin emas.
Ikkinchidan, qayta ishlashga qarang. Yuqori-sifatli alyuminiy qotishma eshik va derazalar, nozik ishlov berish, mukammal o'rnatish, yaxshi muhrlash va oson ochish va yopish. Pastki alyuminiy qotishma eshik va derazalar, alyuminiy profillarning seriyasi va xususiyatlarini ko'r-ko'rona tanlash, qo'pol ishlov berish, frezalash o'rniga arra kesishdan foydalanish, kerak bo'lganda o'rnatmaslik, muhrlanishning yomon ishlashi, noqulay o'tish, nafaqat havo oqishi va yomg'ir va shisha portlashi, Shuningdek, kuchli shamol va tashqi kuch ta'sirida toymasin qismini yoki oynani qirib tashlash yoki yiqitish, odamlarga zarar etkazish oson.
Narxga uchta qarash. Umuman olganda, yuqori{0}}sifatli alyuminiy qotishma eshik va derazalar narxi yuqori ishlab chiqarish narxi tufayli past alyuminiy qotishma eshik va derazalarnikidan taxminan 30 foizga yuqori. Devor qalinligi atigi 0,6-0,8 mm bo'lgan alyuminiy profillardan yasalgan ba'zi alyuminiy qotishma eshiklari va derazalari, valentlik kuchi va oqish quvvati tegishli milliy standartlardan ancha past va ulardan foydalanish juda xavflidir. Bundan tashqari, alyuminiy qotishma eshik va derazalarni qayta ishlaydigan ko'plab o'z-o'zini ish bilan ta'minlaydigan odamlar bor va ular alyuminiy qotishma eshiklari va derazalarining strukturaviy xususiyatlarini va ish faoliyatini tushunishmaydi. Xarajatlarni kamaytirish va burchaklarni kesish uchun sifatsiz mahsulotlardan foydalaning va mahsulotlarning yashirin xavfi nisbatan katta, shuning uchun uni ishlatish odatda mos emas. Oddiy alyuminiy qotishma eshik va derazalar ishlab chiqaruvchilarining mahsulotlarini tanlash yaxshidir. Bu erda alohida nuqta bor: milliy standart profil qalinligi 1,4 mm. Agar yetkazib beruvchi devor qalinligi 1,2 mm yoki 1,0 mm yoki undan ham yupqaroq bo'lgan materialni tanlasa, bu standartga mos kelmaydigan mahsulotdir. Iltimos, sotib olayotganda e'tibor bering.

Materiallarga murojaat qilish uchun 6 ta asosiy jihat mavjud:
⒈Thickness: There are 70 series and 90 series of aluminum alloy sliding doors and windows, and 70 series can be used for aluminum alloy sliding doors inside the house. The aluminum alloy series number indicates the thickness of the door frame in millimeters of the structural dimension. Common aluminum alloy sliding windows include 55 series, 60 series, 70 series and 90 series. The selection should be determined according to the size of the window hole and the local wind pressure value. The aluminum alloy sliding window used as a closed balcony should not be less than 70 series.
⒉ Strength: The tensile strength should reach 157 Newtons per square millimeter, and the yield strength should reach 108 Newtons per square millimeter. When purchasing, the profile can be bent moderately, and it should be able to return to its original shape after letting go.
3. Xromatiklik: Xuddi shu alyuminiy qotishma profili bir xil rang va yorqinlikka ega bo'lishi kerak. Rang farqi aniq bo'lsa, u sotib olish uchun mos emas.
⒋ Flatness: Check the surface of the aluminum alloy profile, there should be no dents or bulges.
⒌Gloss: Aluminum alloy doors and windows should avoid buying profiles with obvious defects such as open bubbles (white spots) and slag (black spots), cracks, burrs, and peeling on the surface.
⒍Oxidation degree: The thickness of the oxide film should reach 10 microns. When purchasing, swipe lightly on the surface of the profile to see if the oxide film on the surface can be wiped off.
