Advantages of PVC Hollow Roof Sheet


PVC Hollow Roof Sheet is a new type of weather-resistant roofing material developed after ASA/PVC roof sheet. The performance of the product has been greatly improved. It is better than other PVC Roof Sheet products. Let's take a look at the specific advantages:


First of all, let’s take a look at the improvements in mechanics. The following figure simulates the common force method of daily use of PVC Hollow roof sheet:


Whether it is a drop hammer impact or ordinary one-way static bending, when the roofing panel surface is under force, the upper surface of the roofing will be subjected to transverse squeezing force, and the lower layer will be subjected to transverse tensile force. When the material is slightly elastic When stretched or squeezed, it will cause the expansion of micro-cracks. During the whole process, the upper and lower layers of the material bear the greatest ultimate force and are the first to be destroyed.


For solid PVC roof sheet, the PVC material in the middle makes little contribution to the mechanics, while the hollow roof sheet absorb the advantages of the I-steel model. The upper and lower layers perfectly solve the mechanical performance problems, and the impact resistance is better than solid PVC roof sheet. To be strong, the test proves that the mechanical properties of PVC hollow roof sheet are much better than solid roof sheet.


The hollow space in the middle saves materials and reduces weight, transportation and installation are more convenient, and it is more beautiful and rich in three-dimensional and design. Due to the strong rigidity of the PVC hollow roof sheet, the purlin spacing during installation is ≤1200mm, which effectively saves material and construction costs.


Secondly, let’s take a look at the other properties of hollow Roof Sheet. Hollow roof sheet are better than ordinary composite roofing in terms of anti-aging, anti-corrosion, heat preservation, heat insulation, and sound insulation. Compared with ordinary heat insulation pvc roof sheet, the heat insulation effect can be different. At 6-8°C, hollow roof sheet have a service life of 4-5 years longer than ordinary composite roof sheet.

Hollow roof sheet have been widely used in the breeding and animal husbandry industry. At present, many high-end factories, market passages, and farmer's markets have also begun to use hollow roof sheet. The use effect is more beautiful and high-end than ordinary composite roof sheet, more acid and alkali resistance, heat insulation and quietness.
