40ft High Cube Modified Shipping Container with Man Door and Roll Up Door

A 40ft high cube modified shipping container with man door and roll up door combines the security and durability of a Corten steel container with convenient personnel access and wide cargo entry, making it ideal for workshops, garages, site storage, and retail applications . This modified unit is perfect for businesses needing both everyday walk-in access for staff and oversized entry for equipment, pallets, or vehicles. Unlike standard containers with double doors only, this unit features a standard 36-inch steel man door (personnel access) plus a wide roll-up door (typically 8ft-10ft wide) for larger items . As a result, you receive a versatile, weatherproof workspace that eliminates the need to open heavy cargo doors for routine access. Learn about container modifications from official HSE guidelines.

Why Choose a Man Door and Roll Up Door Configuration?

Standard containers require opening heavy double doors for every entry. In contrast, this unit’s man door provides convenient daily access for staff, while the roll up door handles larger cargo when needed . Consequently, the 40ft high cube dimensions (9ft 6in exterior, approx. 8ft 10in interior height) provide ample space for storage or workshop activities. Moreover, the roll-up door operates smoothly on galvanised steel tracks with spring-assisted mechanism . Thus, you gain both convenience and functionality in a single modified container.

Key Features of This Modified Container

The man door and roll-up door configuration are the defining features of this unit. The steel man door (typically 36 inches wide x 80 inches high) features a heavy-duty three-point locking system (top, bottom, side) with internal and external handles, plus a deadbolt for security . The roll-up door (typically 8ft-10ft wide x 8ft high) is constructed from galvanised steel slats, operates on ball-bearing rollers, and includes a locking mechanism . The Corten steel construction provides corrosion resistance, while the high cube height offers standing headroom throughout. The CSC safety plate remains valid, allowing intermodal shipping if required . Double doors at the opposite end can be retained or removed depending on configuration .

Man Door and Roll Up Door Placement Options

The placement of doors can be customised to suit your workflow. For example, the man door is typically fitted on the side wall near one end for easy personnel access. The roll up door is commonly fitted on the side wall (creating a garage-style opening) or on the end wall (replacing or supplementing standard double doors). If you need drive-through access, doors can be fitted on opposite sides. For maximum flexibility, retain the original double doors at one end and add both side doors.

Roll Up Door Specifications

The roll-up door is purpose-built for modified containers. The door is constructed from galvanised or powder-coated steel slats (typically 2 inches thick) that roll up into a compact coil above the opening. The galvanised steel tracks and ball-bearing rollers ensure smooth operation with a manual chain hoist (standard) or optional electric motor . The door includes a locking mechanism (typically slide bolts or hasps) for security. The rubber weather seals prevent dust and moisture ingress. The header design transfers wind load into the container structure, maintaining CSC integrity .

High Cube Height Advantage

The high cube height (9ft 6in exterior) provides significant advantages for modified containers. The internal height of approximately 8ft 10in (2,695mm) allows standing headroom for tall users, vertical pallet racking, and clearance for roll-up door operation . If you are converting the container into a workshop, office, or garage, the extra foot of height makes the space feel more open and functional. Standard height containers (8ft 6in exterior, 7ft 10in interior) cannot accommodate the same roll-up door header clearance.
