First, there are three main types of traditional lines.
1, the concrete cast-in-place line must be moulded on-site. The template can only be used once, which wastes a lot. It is easy to expand the mold, and the geometric size is difficult to guarantee. The artificial surface painting on the surface is difficult to achieve the effect and has no insulation performance.
2, GRC line prefabricated is relatively heavy, there are security risks in the high altitude, geometric size of joints is not accurate enough, difficult to handle, and the wall connected with steel expansion bolts, bolt is easy to rust in the outdoors, so that the wall is rusting, influence of exterior wall joint appearance, easy to crack, no water, no insulation performance, but can not prevent cold and heat generation.
3, gypsum line itself is not waterproof, it will be weathered by rain and sunlight, low strength, poor weather resistance, and can not be used outdoors, and the accuracy is poor, no thermal insulation performance.
Two, EPS decorative lines: the use of EPS lines can solve the above problems, making, construction, installation is very simple.
