1. According to the opening method, it can be divided into the flat opening, folio, pushing and pulling, folding, overhanging, eversion, etc.
2. According to the material, it is divided into wooden doors and windows, steel doors and windows, anti-theft doors, automatic doors, plastic doors and windows, revolving doors, iron doors and windows, plastic doors and windows, stainless steel doors and windows, aluminum alloy doors and windows, glass steel doors and windows, aluminum-wood composite doors and windows, etc.
3. According to the materials and functions of doors and windows, they are divided into wooden doors and windows, steel doors and windows, revolving door anti-theft doors, automatic doors, plastic doors and windows, revolving doors, iron flower doors and windows, plastic steel doors and windows, stainless steel doors and windows, aluminum alloy doors and windows, glass steel doors and windows, heat insulation aluminum alloy doors and windows, wood-aluminum composite doors, and windows, aluminum-wood composite doors, and windows, solid wood doors, and windows, sunlight energy house, glass curtain wall, wooden curtain wall, etc.
In fact, aluminum alloy doors and windows are divided into north and south. The north is mainly characterized by thick aluminum materials and stable styles. The most representative is the lattice form, and the most characteristic of the lattices is Tangge. The south is mainly characterized by diversified aluminum shapes and lively styles. The most representative ones are the flower glass styles, which include lattices, ice sculptures, shallow carvings, and crystal shells.
1. Look at the price:
High-quality aluminum alloy folding window due to high production costs, the price is about 30% higher than inferior aluminum alloy doors and windows. Some aluminum alloy doors and windows made of aluminum profiles with a wall thickness of only 0.6-0.8 mm have tensile strength and yield strength that are much lower than the relevant national standards and are very unsafe to use.
2. See the materials:
The aluminum profiles, thickness, strength, and oxide film used for high-quality aluminum alloy folding windows shall comply with the relevant national standards. The wall thickness of the main load-bearing members of aluminum alloy windows should be more than 1.4 mm, the wall thickness of the main load-bearing members of aluminum alloy doors should be more than 2.0 mm, and the tensile strength reaches 157 Newtons per square meter. If the above standards are not met, it is inferior aluminum alloy doors and windows, which cannot be used.
3. Look at the processing:
High-quality aluminum alloy doors and windows, fine processing, careful installation, good sealing performance, and free switch. Inferior aluminum alloy doors and windows, blindly choose aluminum profile series and specifications, rough processing, sawing instead of milling, not installed according to requirements, poor sealing performance, uncomfortable switch, even falling down, destroying and hurting people.c
