Welded plate anchor (welded plate anchor bolt)
The welded plate anchor consists of a threaded rod, a welded pad and a stiffening rib. The pad is fixed with bolts by welding to form an integrated structure of “bolt + pad”. The pad increases the contact area with the concrete, disperses the load and improves stability.

Product definition and structure
The welded plate anchor consists of a threaded rod, a welded pad and a stiffening rib. The pad is fixed with bolts by welding to form an integrated structure of "bolt + pad". The pad increases the contact area with the concrete, disperses the load and improves stability.
Core materials and characteristics
Material:
Bolt: Q235, Q355 or 42CrMo high-strength steel;
Pad: Q235 steel plate, thickness 10-20mm, size designed according to the load.
Features:
High bearing capacity: The pad disperses pressure and can withstand loads from several tons to tens of tons;
Anti-seismic and shock-resistant: The welded structure reduces the risk of loosening and is suitable for vibrating environments;
Anti-corrosion and durable: The whole is galvanized or painted, suitable for harsh environments such as chemical and marine.
Functions and applicable scenarios
Functions:
Fix heavy equipment (such as reactors, steelmaking furnaces), large steel structures (bridges, power towers);
Resist horizontal shear and torque to ensure long-term stable operation of equipment.
Scenario:
Power engineering (substation equipment), chemical industry (storage tanks, reactors), metallurgical plants (rolling equipment).
Installation and maintenance
Installation:
The welding plate foot is embedded in the concrete foundation, and the pad is welded to the steel mesh;
When the equipment is installed, it is connected to the pad by bolts, and a torque wrench is required to ensure the preload.
Maintenance: Regularly check the integrity of the weld to avoid corrosion and strength loss.
Purchase suggestions
Choose the size of the pad according to the weight and vibration frequency of the equipment (e.g., a 200x200mm pad can carry more than 5 tons);
The welding process must comply with the GB/T 5185 standard, and the welding rod must match the steel type (e.g., Q235 uses E43 welding rod).
Comparison and selection guide of three major anchors
| Type | 7-shaped anchor | Welding plate anchor | Umbrella handle anchor |
| Core advantages | Standardization, low cost | High load-bearing capacity, vibration resistance | Flexible embedding, economy |
| Applicable load | 1-5 tons | 5-50 tons | 1-3 tons |
| Typical scenarios | Street lights, light steel structures | Bridges, heavy equipment | Temporary buildings, small machinery |
| Installation method | Embedding + nut fastening | Embedding + welding pad | Embedding + nut fastening |
| Corrosion resistance level | Electrogalvanizing (conventional) | Hot-dip galvanizing + painting (high corrosion resistance) | Galvanizing (ordinary) |
Selection suggestions:
Economic needs: Umbrella handle anchors are preferred, taking into account both cost and function;
High stability needs: Welded plate anchors are the first choice for heavy equipment;
Standardized scenarios: 7-shaped anchors are suitable for most conventional fixing needs.
