1. Embedded Parts Are Required in These Scenarios
Large/Heavy Weathering Steel Screens
For screens with dimensions exceeding 2m×2m or weight over 50kg, embedded parts must be pre-installed in the supporting structure (concrete wall, column, or foundation). The embedded steel plates are welded to the screen's back frame, distributing the screen's weight evenly to avoid local stress concentration and prevent the screen from falling off.Outdoor Wall-Mounted or Freestanding Screens
Wall-mounted screens fixed to concrete facades: Embedded parts anchor the screen to the building's main structure, resisting wind loads, seismic forces, and long-term gravity-this is mandatory for high-rise building exterior screens.
Freestanding screens (e.g., garden partition screens): Embedded anchor bolts in the concrete foundation fix the screen's base, preventing tilting or toppling in strong winds.
High-Strength Installation Requirements
For screens used in public areas (parks, commercial plazas) or harsh environments (coastal, high-wind zones), embedded parts are required to meet safety codes, ensuring the screen can withstand external impacts and environmental stresses.
2. Embedded Parts Are Not Required in These Scenarios
Small/Lightweight Decorative Screens
Screens smaller than 1.5m×1.5m and lighter than 30kg (e.g., indoor partition screens, wall art) can be installed using expansion bolts, chemical anchors, or stainless steel brackets. These methods are sufficient for fixing the screen to concrete or masonry walls without pre-embedding.Installation on Steel Supporting Structures
If the screen is mounted on an existing steel frame (e.g., building steel columns, metal railings), it can be directly welded or bolted to the steel structure-no embedded parts are needed, as the steel frame itself provides sufficient load-bearing capacity.Temporary or Removable Screens
For temporary installations (e.g., exhibition booths, pop-up store decorations), removable fixtures like clamping brackets or magnetic mounts can be used, eliminating the need for embedded parts and avoiding damage to the supporting structure.
3. Key Requirements for Embedded Parts (When Used)
Material Matching: Use hot-dip galvanized or stainless steel embedded parts to prevent galvanic corrosion when in contact with weathering steel. Avoid carbon steel embedded parts, which will rust and stain the screen's patina.
Installation Accuracy: Ensure embedded parts are level and aligned during concrete pouring to avoid misalignment during screen welding/bolting.
Corrosion Isolation: Add non-conductive gaskets (e.g., EPDM rubber) between embedded parts and the weathering steel screen to further reduce corrosion risks.
