Which standards to rely on to identify the quality of plastic-steel door and window equipment

Plastic steel door and window equipment is an item that we will come into contact with in our daily life, and we focus on its safety. But at present, some black-hearted merchants in the market use substandard materials in order to reduce production costs, which contain certain toxic substances, so how should we usually distinguish?

1. Whether the manufacturer is a regular manufacturer

Regular manufacturers of plastic-steel door and window equipment will use non-toxic and harmless raw materials when making door and window equipment. For regular manufacturers, we can also ask for product certification materials to check whether the material specifications meet the requirements.

We can also check the manufacturer's business license, and check the company online to see if the company can be found. And the handwriting on the business license must be clear and neat, and there must be no alterations, because this is likely to be done maliciously by the manufacturer, and those other manufacturers' brands are shining and cheating.

2. View product materials

Some toxic plastic-steel door and window equipment makes the raw materials generally made of lower-quality lead salt mixtures and stabilizers. If these substances are contained in the raw materials of door and window equipment, it means that it is toxic. Because lead is a heavy metal, metal poisoning will occur after long-term exposure to the human body.

Generally, PVC material is used as the material to meet people's needs, because this material is harmless and non-toxic, and will not pose a threat to people's life safety.

3. Check the quality inspection certificate

After purchasing plastic-steel door and window equipment, you must ask the merchant for a quality certificate, and carefully check whether it contains lead, and make sure that there is no lead before it can be used normally. I need to pay great attention to this point, because door and window equipment is an item that we touch every day in our daily life, and we must ensure its safety.

4. Look at the gloss

Under normal circumstances, the color of plastic-steel door and window equipment containing toxic substances will be similar to green and white, which is quite different from pure white and milky white, and is easier to identify.

The longer the door and window equipment containing lead is used, the more turbid the surface will become, but the PVC material will not, so from this point we can also make a preliminary identification of whether the plastic steel door and window equipment is toxic.

Regarding the identification of whether the plastic-steel door and window equipment contains toxic substances, through the above introduction, we know that we can identify it from glossiness, viewing product materials, and viewing quality inspection materials.
