Container House Corner Fitting
Container house corner fittings are key components used to connect and secure various parts of container houses. They are typically made of cast steel and feature standardized dimensions and multiple functional characteristics. The following provides an introduction from aspects such as material, dimensions, functions, and market supply:

Material and Process
Container corner fittings are mostly made of cast steel (such as ordinary carbon steel or stainless steel 304). Some products undergo heat treatment processes to enhance their mechanical properties. For example, the corner fittings produced by Tianjin Jinyu Bairun Machinery Accessories Co., Ltd. are manufactured using the cast steel process. The corner fittings from Cangzhou Huadian Container Accessories Co., Ltd. emphasize "sturdy and corrosion-resistant" features and can handle loading and unloading demands of up to 30 tons. Cast steel ensures the corner fittings' impact resistance and durability during lifting and transportation.
Standardized Dimensions
The internationally standardized dimensions of container corner fittings are 178mm×162mm×118mm, in compliance with ISO standards. This dimension design is suitable for connecting sea freight containers, mobile home frames, and special containers. For example, companies such as Wuxi Gukai Electromechanical Equipment Co., Ltd. and Tianjin Taideli Machinery Accessories Co., Ltd. all offer products in this standard size. Some manufacturers also produce non-standard sizes (such as 218mm×178mm×118mm) to meet the needs of special scenarios like railway containers.
Functional Characteristics
- Connection and Fixation: Corner fittings connect the roof, side panels, end panels, and frames of containers through bolts or welding, forming a stable structure. For example, Yiqi Container Mobile Home Company achieves a single-box self-balancing system through the rigid connection between corner fittings and side beams, reducing material usage by 15%.
- Lifting and Transportation: Corner fittings are designed with lifting holes, allowing them to work with equipment such as cranes and forklifts for overall handling. In the patented technology of Qingdao Leiyue Heavy Industry Co., Ltd., there is an anti-sway electric single-girder crane suitable for lifting energy storage containers, indirectly reflecting the core role of corner fittings in lifting scenarios.
- Seismic Adaptation: In seismic fortification areas (such as Yiqi area), the dual-fixation mode of corner fittings with "wedge-shaped locks + high-strength bolts" can effectively disperse horizontal shear forces and control displacement within 3 millimeters, which is 40% better than the deformation amplitude of conventional welded joints.
Market Supply and Prices
The market supply of container corner fittings is abundant, and prices vary depending on material, process, and specifications. For example:
- The standard corner fittings from Cangzhou Feiyi Container Co., Ltd. are priced at 836 yuan per piece;
- The cast steel corner fittings from Tianjin Jinbin Huaxing Machinery Accessories Co., Ltd. are priced at 113 yuan per piece;
- For bulk purchases, some manufacturers offer services such as 7-day replacement and 48-hour delivery, and support in-depth factory inspections.
Application Scenarios
Container corner fittings are widely used in temporary offices, accommodations, event support facilities, logistics warehouses, and other fields. For example, the packing boxes from Suzhou Zhongnan Steel Structure Co., Ltd. are connected through a full-steel structure frame and corner fittings, with a wind resistance rating of 12 and an earthquake resistance rating of 8, suitable for extreme working conditions; the standard container houses from CIMC Modular Building Investment Co., Ltd. achieve rapid assembly through corner fittings, meeting the needs of temporary buildings.
