Claaification of Drip edges on the Market by Construction Method:
Defect of Post-Installation
The post-installation drip edges should be constructed after surface materials of wall. The construction may break original waterproof layer since the post-installation drips edge should be fixed by nails after drilling holes on the wall.
The silicone should be caulked in the gap between metal and wall for waterproof of the post=installation drip edges. The silicone,however,will be embrittled by UV so that the waterproof will be broken.
Constructing post-installation drip edges requireshigh cost since the complex constructions,such as aloft works,should be operated by professional technicians and machinery.
R&D has developed both of pre-installation and post-installation drip edges.
The post-installation drip edge is dropped caused by the above issues.
R&D provides the best solution only.
Advantages of R&D Drip edge

The elbows,heads,and connectors create high-quality and aesthetic waterproof.
The embedded baseline,holes of connecting piece,and the grooves for adhesives lead easy construction and solid quality.
The draining slope drains water smoothly,and the inverted-V groove avoids backward flow effectively.
