The hardware of sliding doors (also known as sliding doors and sliding doors) is structurally similar regardless of the brand. However, from the hardware and other accessories, it can reflect the grades and differences. Often the hardware and accessories used in the brand sliding door are more expensive. On the contrary, the cheaper the sliding door is in the hardware. The places that are neglected are used more often.
The main structure of the sliding door: vertical frame, upper rail, lower rail, upper horizontal frame, lower horizontal frame, sub-bar, upper and lower pulley, core board, anti-collision strip, positioner
The main material of sliding door material: stainless steel, aluminum, other alloys, now in addition to the low-grade sliding door brand is still using stainless steel as a frame, almost all use aluminum, or alloy.
Surface treatment: lacquered surface, galvanized (chrome), PVC cladding, natural veneer veneer
The main specifications of the sliding door material: 6 m / root of the upper and lower rails, 4.88 m / root of the upper and lower horizontal / middle partition, mullion 4.88 / glass: 1830mm * 2400mm 1600mm * 2400mm wave board: length 2440mm wide 130mm cabinet plate: 1220*2440 sliding door aluminum category national standard aluminum: high-quality aluminum ingots are made by adding certain components of magnesium. Taking high-quality aluminum, which is often used as a sliding door frame, as an example, the aluminum alloy with the aluminum grade of 5019 should have a chemical content of magnesium above 4.5% according to national standards. It has strong hardness, good toughness and is not easy to be oxidized. long lasting. Non-standard aluminum: Made of waste recycled aluminum, the aluminum alloy has poor toughness, insufficient hardness, easy deformation and cracking and oxidation, and short service life.
Main indicators of the quality of sliding door profiles
1. Profile aluminum: Whether to use the national standard aluminum, directly determine the quality and cost of the product / many of the current market use non-standard recycling aluminum, the appearance of the ordinary consumer can not be discerned after treatment.
2, wall thickness (cross section): must choose a product with a cross-cut thickness of 1.2MM or more. The smaller nominal wall thickness of doors and window profiles shall not be less than 1.20 mm, and the measured thickness of aluminum alloy profiles for outer and outer windows shall comply with the provisions of GB/T 8478 and GB/T 8479, respectively.
3, surface treatment: whether the paint surface is smooth, whether the PVC sample has foaming and peeling phenomenon. Sliding door pulley: The sliding wheel is one of the core components of the sliding door, which directly determines the service life and sliding effect of the sliding door. The good sliding door brand will not be lightly on the sliding wheel. The quality of the sliding wheel mainly depends on the quality of the sliding wheel. What is the quality of the bearing and rim material of the pulley? At present, good sliding door brands will use large bearing wheels and resistance nylon wheels.
