Steel Building System
（Diagram of Edge Trim）
（Fully automatic high-precision CNC bending machine）
The extra-long edge trim is able to reduce overlap, thus creating a better sealing performance for the building, while making the appearance more beautiful. The flashing and trimming parts are 180° edge folded, to conceal the exposed cuts and extend the service life of the building.
Made of the same material with the façade panel; the dedicated metal cantilever not only meets the mechanical bearing capacity, but is also durable; the gutter bucket is scientifically and reasonably located, fully takinginto consideration the safety of the drainage route under extreme weather conditions;
