Classification standards for plastic steel profiles, national standards for profiles

The classification of plastic door and window profiles is divided into visible surface thicknesses. Class A: Thick; Category B: Thick; The thickness of class C is not specified, and it is produced according to the double engine agreement. According to the current requirements, the door should be Class A and the window should be Class B.

Legal analysis: the national standard for industrial aluminum profiles is GB6892-2006, but because this standard is lower than the standard for architectural aluminum profiles, we generally use the national standard GB5237-2008 for architectural aluminum profiles to control industrial aluminum profiles. As can be seen from this standard, it was implemented in 2008.

This standard is not developed out of thin air, it is based on GB T 8013-2007 with reference to JIS H8602-1992 and AAMA 612-02 in the United States.

Legal basis: "Regulations on Metal Quality" Article 4 When the original design of the material grade of metal technical supervision is a foreign material, it shall be implemented with reference to the corresponding foreign standard of the original design. When the original design of the material grade is a domestic material, it shall be implemented with reference to the corresponding domestic standard of the original design.

When the original design of the material grade is changed from a foreign material to a domestic material, it shall be implemented with reference to the corresponding domestic standards, but the important material performance indicators shall be implemented with reference to the corresponding foreign standards of the original design.

Introduction: House decoration will naturally involve the installation of doors and windows, and what kind of door and window profiles to choose has become a major problem in front of us. There are many kinds of profiles for making house doors and windows, different profiles have different characteristics, properties, specifications, prices, etc., common door and window profiles are aluminum alloy, plastic steel, etc., among which plastic steel is a cost-effective door and window profile.

So, what kind of profile is plastic steel? What are the general specifications of plastic steel profiles for making doors and windows? What are the outstanding characteristics or advantages of plastic steel profiles?

The following rabbit will take you to understand the plastic steel profile, so that your door and window selection is more accurate.

1. What is plastic steel profile?

Plastic steel is actually a new type of plastic, usually we call it PVC material, and the plastic steel used to make doors and windows is called plastic steel profile. Plastic steel profile is made of a mixture of a variety of substances, of which the main raw material is polyvinyl chloride resin, and the auxiliary materials include stabilizers, fillers, colorants, ultraviolet absorbers, etc. Doors and windows made of PVC profiles are easy to deform, so people will add steel to the inner cavity of PVC profiles, so as to make the doors and windows made of PVC profiles more reliable and solid, which is also the reason why PVC profiles are called plastic steel profiles, and must not be understood as plastic steel profiles are composite profiles of plastic and steel!

At present, plastic steel profiles are mainly used for the production of doors and windows, but they can also be used for the production of accessories for automobiles and other products. The color of plastic steel profiles is often very monotonous, generally milky white, but it can also be made into different colors after attaching the attached film. Windows made of plastic steel profiles can generally be divided into two types: sliding doors and windows, and swing doors and windows.

Second, the advantages and disadvantages of plastic steel profiles relative to other profiles.

For aluminum alloy profiles, its biggest advantage is that it is cheap and suitable for mass consumption, but it is not as hard and firm as aluminum alloy profiles. In addition, after the plastic steel profile is attached to the film, it becomes a color talking about the base plastic steel profile, and the color is much richer than others, which can make your doors and windows more colorful. At the same time, because the plastic steel profile is made of special PVC material, the thermal insulation effect is much better than that of aluminum alloy profile, and the anti-corrosion ability is strong and durable.

Due to the addition of ultraviolet absorbers, the anti-ultraviolet ability of plastic steel profiles is also outstanding.

3. Specifications of plastic steel profiles.

At present, the specifications of plastic steel profiles used to make doors and windows on the market mainly include etc., and these values refer to the width of the cross-section of plastic steel profiles. Generally speaking, sliding doors and windows are mostly made of 88 series plastic steel profiles, while casement doors and windows are mostly made of 60 series plastic steel profiles.

How do we distinguish between good and bad or real and fake when buying plastic steel profiles? Little rabbit is here to give you a tip, to see whether the external color of the plastic steel profile is soft milky white, whether the protective film has bubbles, and to see the anti-counterfeiting identification code, whether the numbers are clear, and no overlap, pay attention to these details in order to buy high-quality plastic steel profiles.
