SANTANG LAKE WIND FARM,

        Steel anchor ring plate, also called anchor plate, upper ring and lower ring, alignment ring and embedment ring, are one of a important accessory in WTG(wind turbine generator) foundation anchor bolt cage system. This product is in the shape of a ring, with hundreds of holes on, and often produce separately due to its big size then splice them into a whole ring by specific rectangle steel plates. These kind of bearing plates are also used for other constructions such as steel structure and foundation anchor bolt which use our bolt’s stress properties.

        Most overseas customers are familiar with  some steel grades for anchor ring plates, for instance,  EN10025 S355JR, S355J0, S355J2, S355NL; ASTM A572/A572M Grade 50. Our Chinese GB/T 1591 Q355B, Q355C, Q355D, Q355NE steels are equivalent, and are acceptable by customers.

Grade Representation:

Steel grade is composed of such three parts as Chinese phonetic alphabet and numerical value of the yield strength and quality classification. For instance, Q345D; thereinto:

Q – is the first letter of the Chinese phonetic alphabet of the word “Qu” of the steel yield strength;

355 – is the numerical value of the yield strength(MPa);

D – is the quality classification; D grade.
