<p>The <a href="https://www.lsbarndoorhardware.com/sliding-door-hardware" rel="noopener noreferrer" target="_blank">sliding door hardware</a> is similar in structure regardless of the brand. But in terms of hardware and other accessories, the grades and differences can be reflected. Often, brand sliding doors with better hardware and accessories are more expensive. On the contrary, the cheaper the sliding door, the easier it is in hardware. The places that are overlooked are used less frequently.</p><p><br></p><p>The main structure of the sliding door: mullion, upper rail, lower rail, upper horizontal frame, lower horizontal frame, sub-slats, upper and lower wheels, core plates, anti-collision bars, locators</p><p>The main materials of sliding door materials: stainless steel, aluminum, and other alloys. Except for low-end sliding door brands that still use stainless steel as the frame, almost all of them use aluminum or alloy.</p><p>Surface treatment: paint, galvanized (chrome), PVC cladding, natural veneer veneer</p><p><br></p><p>The main specifications of sliding door materials:</p><p>The upper and lower rails are 6 meters/piece, the upper and lower horizontal/intermediate strips are 4.88 meters/piece, the mullion is 4.88/piece Glass: 1830㎜*2400㎜ 1600㎜*2400㎜ Wave board: length 2440㎜ width 130㎜ cabinet board: 1220* 2440 sliding door aluminum category national standard aluminum: made of high-quality aluminum ingots with a certain composition of magnesium. Take the high-quality aluminum that is often used as a sliding door frame as an example. For the aluminum alloy with aluminum grade of 5019, according to national standards, its chemical composition magnesium content should be more than 4.5%, with strong hardness, good toughness, and not easy to oxidize. long lasting. Non-standard aluminum: It is made of waste recycled aluminum. The aluminum alloy has poor toughness, insufficient hardness, easy deformation, cracking and oxidation, and short service life.</p><p><br></p><p>The main indicators of the quality of sliding door profile aluminum alloy</p><p>1. Aluminum profile: Whether to use national standard aluminum directly determines the product quality and cost. At present, many non-standard recycled aluminum are used in the market, and the appearance cannot be distinguished by ordinary consumers after treatment.</p><p>2. Wall thickness (cross-section): Be sure to choose products whose cross-section thickness is 1.2MM or more. The smaller nominal wall thickness of the door and window profiles should not be less than 1.20 mm, and the smaller measured wall thickness of the aluminum alloy profiles for exterior doors and windows should meet the requirements of GB/T 8478 and GB/T 8479 respectively.</p><p>3. Surface treatment: Whether the paint surface is smooth, whether the PVC sample is blistering and peeling. 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. A good sliding door brand will not be taken lightly on the sliding wheel. The quality of the sliding wheel mainly depends on the quality of the sliding wheel. The quality of the bearing and rim material of the pulley. The current good sliding door brands will use large bearing wheels and resistance nylon wheels.</p><p><br></p><p><br></p>
