How to choose high-quality color steel sandwich panels?

Page view

Color steel sandwich panel is a commonly used product in current building materials. It is widely recognized by the industry due to its heat insulation, heat preservation, sound insulation performance, light weight, environmental protection, and convenient installation. The color steel sandwich panel is made of two layers of color steel plates on the outside, with core materials (such as rock wool, glass wool, foam, etc.) and glue formed by machine pressing. It is suitable for factory workshops, clean rooms, office partitions, roof tiles, panels Housing, containers, etc.

Alright! I had a preliminary understanding of the performance, components, and scope of application of the color steel sandwich panel, and now I will focus on it! ! How to choose high-quality color steel sandwich panels! ! !

The high-quality color steel sandwich panel is determined by the outer two-layer metal panel and the middle core material. The outer two layers of metal plates are color steel plates. The quality of the color steel plates directly determines the service life of the color steel sandwich panels. First, we observe the substrate and coating thickness to judge. The color steel plate is composed of a base plate and a color coating. The thickness of a good color steel plate substrate is 0.02~0.05mm, and the thickness of the coating is generally below 0.15mm. The thicker the substrate and the coating thickness, the longer the service life of the color steel plate. In order to save costs, some color steel plate manufacturers often use the substrate and the coating to make hands and feet, which affects the service life of the color steel plate. Then observe the cut edge of the color steel plate. Get a color steel plate and observe whether the exposed cut section of the color steel plate is finely crystallized, whether it is gray, dark, and impurities. If the cut surface is finely crystallized and does not gray, it is a good steel plate. Secondly, to listen to the sound, tap the high-quality color steel plate with your fingers or hard objects, and the sound will be loud and crisp. On the contrary, it will be dull and the metal sound is not obvious. Finally, check whether the color steel plate manufacturer has a quality inspection certificate, etc., if necessary, you can go to the manufacturer for on-site inspection.
 
Color steel sandwich panel core materials are also diverse, such as: rock wool, glass wool, foam, silica rock, polyurethane and so on. Good rock wool is smooth to the touch, has uniform density, good strength and toughness, and low water absorption.
 
Finally, remind all the bosses, you get the price and the quality! Too much attention to price, quality will not be guaranteed.
