KHD75 Series Aluminum Door For High Rising Building Aluminium Exterior Doors French Standard Style
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.
