Color steel sandwich panel is a common product in building materials at present, which not only has good flame retardant and sound insulation effect, but also is environmentally friendly and efficient. It consists of upper and lower metal plates and an intermediate polymer insulation core.
There are many kinds of color steel sandwich panels in the market, and the prices are different according to the classification of core materials. Common color steel sandwich panels include color steel sandwich panels with foam, rock wool, glass wool, polyurethane and other core materials. The bubble is cheaper, and 30 yuan is flat around; The color steel sandwich panel of rock wool/glass wool is around 50 yuan, and the color steel sandwich panel of polyurethane is around 90 yuan. Hand-made color steel sandwich panels generally have flame-retardant paper honeycomb, aluminum honeycomb, glass-magnesium grid and other core materials, which are collectively called purification panels. The price of this color steel sandwich panel is relatively high, generally around 100 yuan.
In addition to the core material, the specifications, models, thickness, purchase channels and other factors of color steel plate will also affect its price. (The above price source network is for reference only)
Second, how to choose high-quality color steel composite plate
Color steel plate is a composite plate composed of substrate and coating, also called color steel sandwich plate. When purchasing color steel plates, you can choose high-quality color steel plates through the following aspects:
1, depending on the thickness of coating and substrate, the substrate of a good color steel plate should be controlled between 0.02 and 0.05 mm, and the coating should be controlled below 0.15 mm.
2. Observe the cross section of the color steel plate. If the quality is good, the crystal is fine, without impurities, and will not be gray and black.
3. Tap the color steel plate gently with your hand, and the good quality will make a very loud and crisp sound; If the sound is dull and you can't hear the sound from the metal, it means the quality is poor.
4. When purchasing, you can ask the merchant to issue a certificate. The best way is to go to the production site to see, mainly to see its working environment, whether all processes are formal, but also to see the reputation of enterprises.
5. When buying color-coated steel plates, it is necessary to clarify the principle of getting what you pay for, and avoid buying products that are much lower than the market price, so as not to buy inferior color-coated steel plates.
