Container House Corner Fitting Size

The standard size of the corner fittings for container houses is 178mm×162mm×118mm. Here is a detailed introduction to container corner fittings:

I. Size Standards and Implementation Specifications The size of container corner fittings adheres to the ISO1161 standard established by the International Organization for Standardization (ISO). This standard clearly specifies that the length, width, and height of corner fittings are 178 millimeters, 162 millimeters, and 118 millimeters, respectively. This standard applies to the vast majority of dry cargo containers worldwide, ensuring the structural interchangeability of corner fittings produced by different manufacturers and providing a unified basis for container stacking, lifting, and transportation.

II. Material and Manufacturing Process Corner fittings are typically made of high-strength cast steel materials (such as JIS SCW480). This material combines high strength with good toughness, enabling it to withstand the enormous stresses generated during container stacking and lifting. In terms of manufacturing process, corner fittings need to be formed through precision casting or forging processes to ensure dimensional accuracy and internal structural density. Subsequently, surface treatment (such as gray zinc-rich primer spraying) is carried out to enhance corrosion resistance and extend service life.

III. Functions and Design Features Corner fittings are the "key nodes" of containers, and their design incorporates multiple functions:

1. Structural Support: As the vertices of the container frame, corner fittings are connected to corner posts, end beams, and other components via bolts to form a stable rectangular structure that bears the weight of the cargo and external loads.
2. Lifting Interface: Standard-diameter circular holes are provided on the top and sides of corner fittings, which can cooperate with lifting devices (such as twist locks and turn locks) to enable rapid lifting and handling of containers.
3. Stacking Positioning: The raised edges and hole positions of corner fittings allow upper and lower containers to be precisely aligned during stacking and fixed with twist locks, ensuring stacking stability.
4. Protective Function: As the outermost components of the container body, corner fittings can disperse local impact forces and protect the container structure from damage.

IV. Types and Identification According to their positions, corner fittings are divided into four types:

• BL (Left Bottom Corner Fitting) and BR (Right Bottom Corner Fitting): Located on both sides of the container bottom, usually equipped with drainage holes at the bottom.
• TL (Top Left Corner Fitting) and TR (Top Right Corner Fitting): Located on both sides of the container top, possibly equipped with ventilation holes or identification slots at the top. The hole layout and structural details of each type of corner fitting may vary slightly, but all must comply with the ISO1161 standard to ensure versatility.
