Container House Door Lock

Admin September 15, 2026

Container house door locks typically use standard container door fittings, including lock heads, lock bases, brackets, bushings, and door handles. Each set of door locks weighs approximately 5 kilograms, and a single standard container requires 4 sets of door lock fittings.

1. Core Component Composition
The container door lock system consists of components such as lock heads, lock bases, brackets, bushings, and door handles. The lock head and lock base are installed on either side of the door frame, achieving closure and locking through mechanical structures. Brackets come in large and small sizes and are used in conjunction with bushings to enhance structural stability. The door handle provides an interface for opening and closing operations, with some models equipped with lock catches or positioning rings to optimize sealing. For example, the standard door lock fittings manufactured by Cangzhou Xinhe include 1 left-facing lock head, 1 right-facing lock base, 2 large brackets with bushings, 2 small brackets with small bushings, 1 door handle, 1 lock catch, and 2 positioning rings per set.

2. Specifications, Parameters, and Adaptability
The door lock system adopts a modular design, with each set weighing approximately 5 kilograms and suitable for 30-ton steel fixed containers. Depending on the size of the container, a single standard unit (such as a 20-foot or 40-foot container) requires the installation of 4 sets of door lock fittings to ensure structural strength. The lock rod, as an extension component, needs to be custom-made according to the size of the container door frame, with prices calculated based on actual needs.

3. Production Process and Materials
The lock heads, lock bases, and door handles are manufactured using forging processes, while the brackets are stamped parts, and the bushings are injection-molded. This composite process ensures mechanical strength while optimizing the corrosion resistance and assembly accuracy of the components. For example, Cangzhou Xinhe's products undergo chemical degreasing, phosphating treatment, and electrostatic spraying processes to provide rust-proof surfaces on the door locks, making them suitable for long-term outdoor use.

4. Suppliers and Procurement Recommendations
Major domestic suppliers include companies such as Cangzhou Xinhe Container Manufacturing Co., Ltd., which offer bulk customization services. When procuring, note the following: Bulk orders (≥50 sets) are eligible for unit price discounts; the door lock system must strictly match the container model; the length of the lock rod must be measured separately for confirmation; some suppliers require advance deposits or freight collect payments. For example, Cangzhou Xinhe's standard door lock fittings are priced at 55 yuan per set (5-49 sets) or 50 yuan per set (≥50 sets), with delivery completed within 2 days.
