The main structure of the sliding door is:
Mullion, upper rail, lower rail, upper horizontal box, lower horizontal box, sub-shelf, upper and lower pulleys, core board, bumper, positioner slide door Material:
Stainless steel, aluminum, and other alloys are now mostly made of aluminum or alloys, except for the low-end sliding door brands that use stainless steel as the border.
The main specifications of lacquer, galvanized (chrome), PVC cladding, natural veneer sliding door materials:
The upper and lower rails are 6 meters/root, the upper/lower horizontal/middle partitions are 4.88 meters/root, the mullion 4.88/glass: 1830mm*2400mm1600mm*2400mm
Wave board: length 2440mm wide 130mm
Cabinet board: 1220*2440
Sliding door aluminum category GB aluminum: high-quality aluminum ingots made of certain ingredients made of magnesium. Taking high-quality aluminum, which is often used as a sliding door frame, as an example, the aluminium alloy with a 5019 aluminium profile, according to national standards, has a magnesium content of 4.5% or more. It has strong hardness, good toughness, and is not susceptible to oxidation. long lasting.
(Reference Standard: Deformed Aluminum and Aluminum Alloy Grades and Chemical Compositions (Extracted from GB/T3190-1996) Page 10, Table 1, continued)
Non-standard aluminum: made from recycled aluminum, the aluminum alloy has poor toughness, insufficient hardness, easy deformation, cracking and oxidation, and short service life.
Sliding door aluminum profiles of the main indicators of good or bad quality 1, aluminum profile: whether the use of national aluminum, directly determine the product quality and cost / current market, many non-standard recycling of aluminum, after the appearance of ordinary consumers can not distinguish the naked eye.
2. Wall thickness (cross-section): Be sure to choose a product with a cross-cut thickness of 1.2 mm or more.
(The reference standard "National Standard for Aluminum Alloy Building Profiles GB 5237.1-2004" section 184.108.40.206 The minimum nominal wall thickness of doors and window profiles shall not be less than 1.20 mm, and the minimum measured wall thickness of aluminum alloy profiles for exterior doors and windows shall be in accordance with The provisions of GB/T 8478, GB/T 8479.)
3. Surface treatment: Whether the paint surface is smooth or not, whether the PVC sample has blistering or peeling phenomenon.
Sliding door pulleys:
The sliding wheel is one of the most important parts of the sliding door and directly determines the service life and sliding effect of the sliding door. The good sliding door brand will not be taken lightly on the sliding wheel. The quality of the sliding wheel mainly depends on the bearing of the pulley. And the quality of the rim material. At present, good sliding door brands will use large bearing wheels and resistance nylon wheels.
