Product Description
Product Overview
This product is a perforated iron plate square washer complying with the DIN436 standard, manufactured from Q235 carbon steel with a performance grade of 4.8 and achieving Grade A precision. It is designed as a square thin plate with a central hole, featuring a simple and sturdy structure. The surface is treated with hot-dip galvanization, forming a thick zinc layer that provides excellent rust and corrosion protection. It is suitable for occasions requiring large-area support, pressure distribution and ground connection conduction in electrical equipment and mechanical connections.
Core Advantages
-
Excellent Rust and Corrosion Resistance: The thick and uniformly covered hot-dip galvanized layer provides long-term rust protection far superior to ordinary electroplating, especially suitable for outdoor and humid environments.
-
Reliable Mechanical Support and Ground Connection: The square perforated structure provides a stable support surface, effectively dispersing pressure and preventing connectors from crushing soft materials. At the same time, it facilitates ground connection conduction.
-
High Cost-Effectiveness: The Q235 carbon steel material combined with the hot-dip galvanizing process ensures excellent rust prevention performance while having outstanding cost-effectiveness.
-
High Standard Compliance and Versatility: Complying with the international DIN436 standard, it has precise dimensions, strong versatility in industries such as low-voltage electrical equipment and mechanical manufacturing, and is easy to replace.
Applicable Industries
-
Power and Electrical Engineering: Ground connection and support washers for equipment such as high and low voltage switchgear, distribution boxes, transformers, and circuit breaker terminals.
-
Outdoor Steel Structures and Facilities: Bolt connection and rust prevention treatment for exposed environments such as communication base stations, street light poles, traffic signal poles, and outdoor cabinets.
-
Industrial Equipment Manufacturing: Ground connection and anti-loosening connections for mechanical equipment bases, frames, and casings, as well as contact surfaces requiring corrosion protection.
-
Construction and Infrastructure: Pressure distribution for fastening points requiring long-term rust prevention, such as building curtain wall steel structures, bridge accessories, and guardrails.
-
New Energy Equipment: Installation and ground connection for outdoor equipment such as photovoltaic support systems, wind power generation equipment foundations, and energy storage cabinets.
-
Agricultural and Marine Facilities: Connecting parts in corrosive environments such as greenhouse structures, aquaculture equipment, and wharf facilities.
Warm Tips
-
The hot-dip galvanized surface has high hardness, but the coating may have slight unevenness. Avoid excessive scratching during installation.
-
Although hot-dip galvanizing has strong rust prevention ability, its applicability still needs to be evaluated or additional protection measures taken in extreme chemical corrosion or long-term immersion environments.
-
During installation, ensure that the washer is clean and closely attached to the connection surface to ensure the best electrical conductivity (if used for grounding) and pressure distribution effect.
