Dinggu began in 2002 in Zhongshan City, Guangdong Province, and is only separated from Xiaolan Town, Zhongshan Town, the "Southern Locked City". Although Dinggu's main business covers security door locks, it has also made great achievements in customizing wardrobes and corresponding boutique hardware, and its overall wardrobe is a famous brand product in Guangdong Province, and has been rated as "China's top ten brands of whole house customization" by China Wardrobe Network for many times. As an important accessory of custom wardrobe, hinge has a good reputation among consumers, and after nearly 20 years of development, Dinggu has become one of the world's top 15 hinge manufacturers.

Whether it is cold-rolled steel or stainless steel, the weight of the two-stage force damping hinge is about 100g, which is better than Huitailong in terms of design. The configuration of the damping system is the same as that of Huitailong, with copper cylinders for 304 stainless steel models and conventional metal cylinders for ordinary stainless steel and cold-rolled steel. However, due to the standard two-stage force, the price of the top 304 stainless steel damping hinge is as high as 31 yuan, which is almost the same as Hettich. If the budget is insufficient, in the room, living room, office and other non-humid environments, you can choose cold-rolled steel or ordinary stainless steel hinges, which are sold for 18-25 yuan. The price of a force hinge is between 13-30 yuan, which is not as cost-effective as Huitailong.

The conventional door hinge configuration of the top solid is similar to that of Häfele, the material is brushed stainless steel, and the weight of the 4-inch model is 240g, but the price is nearly half cheaper, which is a cost-effective choice among the big brands. However, although the appearance of the so-called mother and son hinge and butterfly hinge is high, it is actually a piece of material for two pieces, and the price is the same as that of the book page hinge.
