1. Customization Range & Constraints
Maximum Size: Limited mainly by processing equipment capacity and transportation conditions.
For flat-panel screens: Common maximum dimensions are up to 12m × 2.5m (subject to the size of laser cutting machines or CNC plasma cutters). Larger screens can be fabricated by splicing multiple panels with welding or bolted connections.
For three-dimensional (3D) screens (e.g., curved or folded designs): The maximum size is adjusted based on bending machine capabilities and structural stability requirements.
Minimum Size: No strict limitations-small screens (e.g., 0.5m × 0.5m for decorative wall art) can be precisely cut and processed.
2. Key Processing Techniques for Size Customization
Laser Cutting/CNC Plasma Cutting: These methods enable precise cutting of weathering steel plates into any desired size, with smooth edges and high dimensional accuracy (tolerance ≤ ±0.5mm). They are suitable for both flat and complex-shaped screens.
Welding & Splicing: For oversized screens that exceed single-panel processing limits, multiple weathering steel plates can be spliced using low-hydrogen welding techniques (to avoid cracking). The welds can be polished to maintain a uniform aesthetic, or left exposed to develop patina alongside the base material.
Bending & Forming: Custom-sized screens can be bent into curved, angular, or folded shapes to fit specific architectural designs (e.g., curved building facades, sloped garden partitions).
3. Considerations for Custom Size Screens
Structural Stability: Oversized screens (especially those over 3m in height/width) require reinforced back frames (made of weathering steel or stainless steel) to prevent deformation under wind loads or gravity. Embedded parts or supporting brackets may also be needed for installation.
Transportation & Installation: Extra-large screens should be split into manageable sections for transportation to avoid damage during transit. On-site splicing and installation need to follow strict alignment standards to ensure the final size matches the design requirements.
Patina Uniformity: Spliced screens may develop slight patina color differences between panels if not processed uniformly. To avoid this, apply artificial patina acceleration to the entire assembled screen, or select panels from the same batch of weathering steel.
