First of all, we have determined that the use of single layer roof sheet roll forming machine, basically will be selected among the commonly used models in China, such as roof tiles 840, 850, 860 and wall tiles 900, 910 and so on. So what kind of market requirements are based on double layer roll forming machine? Because in recent years, the main market targets of the steel metal roof industry have been converted to small and medium-sized cities and towns and villages, because the owners of metal roof equipments are operated in personal form. Based on such customer groups, we rarely have very Large area and large investment.

Therefore, double-layer color steel tile equipment is popularized under such market requirements. The double layer roll forming machine can be combined with any two types of single layer roof machines to be produced on the platform equipment. The equipment is divided into two layers, and the upper layer and the lower layer respectively produce different model types. Therefore, the effect of the double layer roll forming machine can be achieved. The same equipment can produce two different versions. Compared with purchasing two different types of single-board devices, it saves space and saves costs. . Therefore, the proportion of double layer roll forming machine on the market is also increasing. The classification of specific double layer roll forming machine models will continue to be updated in future articles.
