How to choose Sliding Door:

Frame profile
The base materials of sliding doors generally include aluminum alloy and plastic steel. Because aluminum alloy has the characteristics of light weight and high strength, it is a high-grade material of sliding door base material, which has gradually replaced plastic steel products. Aluminum alloy is divided into ordinary aluminum magnesium alloy and aluminum titanium magnesium alloy. Metal titanium has the characteristics of high strength, small proportion and high toughness. Therefore, its price will be several times more expensive. In addition, advanced surface treatment includes anodic oxidation, electrophoresis, coated carbon spraying and other processes, which have higher hardness and aesthetics than simple spraying and electroplating [1].
thickness
If glass or silver mirror is used as door core, 5mm thick is generally used; If the wooden board is used as the door core, the thickness of 10mm is the best. In order to save material costs, some manufacturers use thinner wood boards (8mm or even 6mm) instead. The thin wooden board looks frivolous and shaking when pushed and pulled, and its stability is poor. Moreover, it is very easy to warp and deform after using for a period of time, blocking the guide rail, resulting in poor push and pull and affecting the normal use.
Paint finish
The paint surface has undergone double-layer branding before spraying and transfer, that is, surface dedusting and impurity removal branding, which increases the adhesion of the paint surface and the paint surface will never fall off. However, the profiles of some small manufacturers are simply branded or even not branded, so the paint surface is easy to fall off and the texture is not clear.
The profile surfaces of the manufacturers of large sliding doors are processed by the company itself, and then processed by imported advanced technology. The product paint is smooth and delicate, uniform and full, and the texture is clear. The manufacturers of small sliding doors wholesale the finished colored profiles from the profile factory. The surface cannot be treated by themselves. The color is single and the door shape color is not interchangeable. For example, there are problems such as profile scratch during transportation or installation, mismatch with the color of the original door during material replenishment, large color difference and so on.

Glass Description

Double layer insulating glass
Insulating glass is to separate two pieces of glass by effective sealing material and spacer material, and a desiccant absorbing water vapor is installed between the two pieces of glass, so as to ensure that the inner part of insulating glass is a dry air layer for a long time, without water vapor and dust; At the same time, insulating glass is easy to carry out mass industrial production, so insulating glass is widely recommended in new buildings.
Two pieces of flat glass are isolated by molecular sieve, filled with dry air in the middle and sealed by organic adhesive around.
It has good heat insulation and sound insulation performance, and can be used as windows for buildings, refrigerated cabinets, railway vehicles, etc.
