德国采购需求：LED网格，LED海报，LED显示屏，LED窗帘，4K LED屏幕，高清LED屏幕

We're kicking off a permanent media art installation on a decommissioned escalator and are keen to explore your modular LED screen solutions. The setup will be indoors, covering an area of 8.4m² (14m long by 0.6m high). We need interconnected LED modules or flexible LED strips that can be mounted directly on the steps. Additionally, LED mesh could also work if it fits our requirements. Key specs include a pixel pitch of ≤10mm and a brightness of ≥600 nits. We aim for curved mounting along the step edges, with a bending radius of around 20cm. Please share your product recommendations, ideally from your Umini or flexible series. We'd also like to know the lead time for production and delivery, along with a detailed quote that includes all necessary components. It would be great to have installation guidelines for curvy surfaces and references from similar staircase projects you've completed. Thanks!
