Heavy Duty Plastic Crates with Lids

Heavy industries require crates that are much stronger than standard storage bins. Metal parts, castings, and heavy tools can quickly damage ordinary crates. We use extra-thick walls and reinforced rib structures for our heavy-duty crates. They can withstand heavy loads and rough handling for many years. This helps heavy manufacturing and auto parts companies reduce their cost per use. Our factory is located in Qingdao. We have extensive experience in high-volume production of heavy-load crates. We specialize in strength optimization for heavy-duty structural parts. Our heavy-duty plastic crates with lids are designed for the most demanding applications.

We manufacture our heavy-duty crates from PP or HDPE. The walls and base are reinforced with extra thickness. The dense rib structures provide excellent load-bearing capacity. The crates can withstand repeated loading of heavy parts and rough handling without cracking or deforming. The materials are modified for improved aging resistance and low-temperature performance. They maintain strength in cold storage environments and outdoor conditions. They do not become brittle or deteriorate easily over time.
Although using more material increases production costs, the extended service life significantly reduces the cost per use. The lid provides additional protection by keeping dust away and securing items during transportation. Our 150 to 800-ton horizontal injection molding machines can produce heavy-duty crates in different sizes and load capacities. You can send us drawings or samples. We will review the load requirements and structural reinforcement design. We will then provide an accurate cost estimate and delivery schedule.

We inspect the load capacity and impact resistance of every production batch. We perform full-load weight tests and repeated drop tests on each batch. These tests simulate heavy-duty handling conditions. This ensures that the crates can withstand rough use without cracking or deformation. We measure the wall thickness of every crate to confirm that it meets the design specifications.

We accept third-party inspections. You are also welcome to visit our factory for on-site production monitoring. Our regular lead time is 20 to 30 days. The minimum order quantity is 300 pieces. Our products comply with RoHS, REACH, and food-contact requirements. We nest the crates together for packing. This packing method is suitable for bulk long-term purchases by heavy industries, auto parts companies, and cold chain businesses.
