CMG Containers, a premier U.S. supplier of durable shipping container solutions, announced expanded availability of double door containers designed to offer optimal access, flexibility, and space utilization for businesses across logistics, construction, warehousing, retail, and industrial markets. With demand rising for container solutions that support more efficient workflows, CMG's double door units—also known as tunnel containers—are becoming a strategic choice for organizations requiring full-length access and improved load distribution without sacrificing security or strength.
Traditional end-opening containers restrict access to a single opening, limiting visibility and workflow flexibility. In contrast, double door shipping containers feature large doors at both ends, creating a tunnel-like system that enables goods to pass straight through without obstruction—ideal for pallet jacks, forklifts, and conveyor systems. This design innovation makes tunnel containers exceptionally useful in scenarios relying on continuous movement, rapid loading/unloading, and organized storage.
"Full-length passage through a container is more than a convenience — it fundamentally changes how goods are handled," said Ken Malkoç, CEO of CMG Containers. "Our double door containers empower operators to move materials more efficiently and safely, reducing handling time and streamlining workflow." The company offers detailed information about these solutions at https://www.cmgcontainers.net.
Double door containers are versatile solutions with applications across multiple industrial and commercial sectors. Warehouses and distribution centers can improve staging, throughput, and internal logistics flows, while manufacturing facilities can simplify raw material intake and finished goods dispatch. Retail operations can expedite seasonal inventory movement, and construction sites can enable easier access to tools and building supplies. By enabling movement through the container from either end, operators can drastically cut down on wasted time and labor costs while improving inventory management.
CMG Containers' double door units stand out for their combination of structural integrity, accessibility, and built-in security. Key features include tunnel-style access through both ends that improves productivity for loading/unloading cycles, construction from heavy-gauge corten steel with reinforced framing, weather-tight seals that protect contents from environmental exposure, ISO compliance for easy transport and stacking, and dual locking points on each set of doors providing added theft resistance. These features make the containers ideal not only for storage but for dynamic environments where materials continuously enter and exit the space.
The company now offers both 20ft and 40ft double door container options, allowing customers to choose the right fit for their operational footprint and storage volume. The compact 20ft model delivers efficient square-foot access with full internal visibility, ideal for smaller facilities with limited yard space, job sites needing organized tool and material storage, and retail storage boosters. The 40ft model significantly increases usable internal volume while preserving the full tunnel access advantage, perfect for large-scale logistics and distribution operations, high-volume retrieval systems, and industrial stockrooms requiring aisle-like container access.
In addition to standard container features, CMG Containers provides tailored modifications to enhance function and usability for specialized projects. Popular modification options include custom shelving and racking systems, internal lighting and electrical setup, climate control and insulation installations, roll-up doors or side access points, and branded exterior finishes for corporate identity. These enhancements transform a double door storage container into a purpose-built work environment—whether for staging inventory, housing equipment, or serving as a modular workspace.
One of the most frequent concerns with modified or specialized containers is durability. CMG's tunnel containers are manufactured from premium finished corten steel with reinforced floors and structural beams engineered to withstand heavy use, rough handling, and diverse weather conditions. Weather-tight gaskets and secure door seals ensure contents remain dry and protected. "Durability is non-negotiable," Malkoç added. "Whether a client needs to store tools on a busy construction site or manage pallets of goods in a bustling warehouse, our containers are built to last — and to perform."
As businesses evolve, traditional storage approaches can slow down throughput and increase operational bottlenecks. Double door containers help remove these constraints by enabling streamlined movements of goods without backtracking, supporting faster throughput with minimized handling steps, allowing flexible organization of internal space, and integrating seamlessly into industrial workflows. These benefits make double door containers not simply storage units, but productivity-enhancing tools that can transform operational efficiency across multiple industries.
