Stabilize the rust layer to eliminate loose rust powder (core measure)
Factory pre-rusting + transparent sealing: Prior to installation, subject the screen to controlled pre-rusting (2–4 weeks in a humidity-controlled environment) to form a dense, non-powdery patina. Then coat the entire surface (including edges and welds) with a matte or satin transparent ceramic glaze (30–40μm thickness). The glaze locks the rust color and texture, preventing loose rust from shedding and mixing with dust, while remaining invisible to preserve the material's industrial or retro aesthetic. Avoid glossy coatings that create a "plastic-like" finish and disrupt the natural rust texture.
Localized edge reinforcement: Polish and seal sharp edges or cut surfaces (prone to initial rust flaking) with a weathering steel-specific touch-up patina and glaze, eliminating micro-rust points that attract dust and cause uneven discoloration.
Optimize structural design to reduce dust accumulation
Avoid closed or concave structures: Design the screen with open, streamlined patterns (e.g., large perforations, linear slits) instead of deep grooves, hollow cavities, or overlapping layers-these closed areas easily trap dust and are hard to clean, ruining the screen's neat aesthetic. For decorative patterns, ensure gaps are ≥5mm wide for easy wiping with a soft brush or cloth.
Elevate installation and add hidden drainage: Mount the screen 5–10cm away from walls or ceilings to create airflow space, preventing dust from accumulating in the gap between the screen and the wall. For floor-standing screens, add a detachable stainless steel base with small drainage holes to collect dust and condensed moisture, avoiding dust adhesion to the bottom rust layer.
Adopt targeted cleaning and maintenance to preserve aesthetics
Gentle dust removal routines: Clean the screen once every 2–4 weeks with a static dust cloth or low-power (≤1000W) vacuum cleaner (with a soft brush attachment) to remove surface dust without scratching the glaze or rust layer. For stubborn dust in pattern gaps, use a soft-bristled artist brush instead of abrasive tools (steel wool, wire brushes) that damage the protective layer.
Avoid water or chemical cleaners: Interior environments have low corrosion risks, so never rinse the screen with water (which can cause water stains on the rust surface) or use acidic/alkaline detergents (which erode the glaze and alter rust color). For minor stains, wipe with a slightly damp microfiber cloth and immediately dry with a dry cloth.
Regular glaze inspections: Check the glaze layer every 6–12 months for cracks or peeling (especially in high-traffic areas). Touch up damaged areas with matching transparent repair glaze to maintain the barrier against rust and dust, ensuring long-term aesthetic consistency.
Coordinate with interior environment to enhance overall harmony
Match with dust-resistant surrounding materials: Pair the weathering steel screen with smooth, non-dusting materials (e.g., polished concrete floors, glass partitions, leather furniture) to reduce overall indoor dust sources and highlight the screen's rust texture by contrast. Avoid pairing it with lint-prone fabrics or porous stone that traps dust and makes the screen appear messy.
Control indoor humidity and airflow: Maintain indoor humidity at 40%–60% (via dehumidifiers or air conditioners) to prevent excessive moisture from causing localized re-rusting of the screen, and ensure gentle airflow (e.g., ceiling fans on low speed) to reduce dust settling on the screen surface.
