This square steel washer is engineered for facade support systems, manufactured from carbon steel (Q235 / Q355) with a hot-dip galvanized (HDG) surface treatment. It delivers a cost-effective, durable solution suitable for curtain wall projects in dry, inland environments. Hot-dip galvanizing provides the highest level of corrosion resistance and is the standard choice for steel-structured facades in China. For coastal areas exposed to salt spray or highly corrosive conditions—such as curtain walls near the sea—SUS316 stainless steel is the preferred material.

• Larger bearing area for improved load distribution
• Flat, thick, and rigid construction for structural stability
• Corrosion resistance via hot-dip galvanizing
• Stable positioning at bolted connection points
• Flexible specifications to match varied project requirements

1. Stone and Terracotta Panel Facade Used at connection points between mounting hardware or angle brackets and the primary steel structure, as well as at bolt-bearing surfaces, to prevent aluminum angle brackets from being crushed or deformed under pressure.
2. Glass Curtain Walls Used at connection nodes—such as mullion-transom connectors, embedded plates, or post-installed chemical anchors—where backing plates are placed under bolt heads to distribute tensile forces.
3. Aluminum Panel, HPL, and ACP Facades Used at support nodes connecting to the steel structure.
