Parcel lockers are used in residential communities, commercial buildings, logistics facilities, and other locations where parcels need to be stored and collected.
For parcel locker equipment manufacturers, the metal cabinet is more than an external cover. It provides the physical structure for the locker compartments, supports door and access interfaces, and helps protect the equipment during daily use.
A poorly manufactured cabinet can create problems with panel alignment, door fit, surface appearance, and structural durability.
For this project, the focus was on manufacturing a custom SPCC sheet metal parcel locker enclosure that met requirements for anti-vandal construction, continuous welding, scratch resistance, and IP65 protection.
The project demonstrates why enclosure manufacturing needs to address structural fabrication and surface quality together.
Parcel lockers can experience repeated opening and closing, contact with parcels and handling equipment, and exposure to public environments.
The enclosure therefore needs to satisfy several requirements at the same time.
A parcel locker cabinet needs a structure suitable for frequent public use.
Panel connections, welded joints, and door interfaces all contribute to the overall construction. The enclosure must be manufactured according to the required geometry and structural specifications rather than treated as a simple sheet metal box.
For custom projects, the appropriate panel thickness, reinforcement, and joining method depend on the customer's drawings and intended application.
Continuous welding was a specified requirement for this project.
The welding approach needs to be considered alongside panel fit-up, joint accessibility, and the intended surface finish.
Welding can introduce heat distortion into sheet metal, particularly when multiple panels form a large cabinet. A suitable fabrication sequence helps manage distortion and supports the dimensional consistency needed for subsequent assembly.
The goal is to produce the required cabinet structure without creating unnecessary rework during finishing or installation.
Parcel lockers are handled frequently, making surface appearance an important consideration.
Scratches and inconsistent finishing can affect the perceived quality of the finished equipment, especially when cabinets are installed in visible public areas.
The surface-treatment specification should therefore be established before production. Material preparation, handling during fabrication, and finishing requirements all need to be considered as part of the manufacturing process.
IP65 was specified for this parcel locker project.
Achieving the required protection level depends on the complete enclosure configuration, not just the main sheet metal panels.
Door interfaces, joints, openings, and other penetrations need to be considered together. Where seals or other protective components are required, their interfaces must be compatible with the enclosure structure.
The final protection level should be verified using the appropriate test and acceptance requirements for the specific product.
The enclosure was manufactured from SPCC sheet steel.
SPCC is commonly used in cold-rolled sheet metal applications where forming, fabrication, and surface appearance are important considerations.
For a custom parcel locker cabinet, sheet steel can be processed into the panels and structural components required by the customer's design.
Material selection should account for:
Required structural strength
Panel dimensions and geometry
Bending and welding requirements
Surface-finish specifications
Installation environment
Corrosion-protection requirements
SPCC is not inherently corrosion-proof. For cabinets installed outdoors or in demanding environments, the complete material and coating specification should be evaluated against the intended service conditions.
Selecting the material and finish together helps align manufacturing with the actual application rather than relying on material names alone.
A parcel locker enclosure typically consists of multiple sheet metal panels and structural interfaces.
The exact configuration depends on the cabinet design, including the number and arrangement of compartments, doors, mounting points, and access openings.
During fabrication, the relationship between these components is important.
If panels are cut or bent incorrectly, the resulting assembly may require adjustment. If welding causes excessive distortion, door openings and adjoining surfaces may become difficult to align.
For custom sheet metal cabinets, the manufacturing process should therefore follow the approved drawings and account for the sequence of cutting, forming, joining, and finishing.
This is especially important when the enclosure has multiple visible surfaces and repeated interfaces.
Continuous welding can help meet the specified joint requirements, but the welding sequence also affects dimensional stability.
Heat input may cause sheet metal panels to move or distort. On a multi-panel cabinet, small changes can accumulate and affect the fit of adjoining parts.
Manufacturing considerations include:
Consistent panel preparation and fit-up
Appropriate welding sequence
Suitable fixturing where required
Inspection of critical cabinet dimensions
Verification of door and panel interfaces before finishing
The inspection points should be selected according to the customer's drawing and the features that matter most during final assembly.
For a parcel locker manufacturer, this helps reduce the risk of receiving cabinets that need extensive adjustment before the doors, locks, or other components can be installed.
The external surfaces of parcel lockers are highly visible and frequently handled.
Surface quality depends on more than the final coating process. Scratches, dents, weld marks, and handling damage can originate during different stages of production.
A practical manufacturing approach considers surface protection throughout the process.
This includes handling sheet metal carefully, controlling the condition of visible surfaces after fabrication, and defining which areas require particular cosmetic attention.
The required coating and finish should be specified according to the product's appearance, operating environment, and customer acceptance criteria.
For projects with multiple cabinet panels, the finish should also be considered across adjoining surfaces to maintain a consistent appearance after assembly.
When a parcel locker project specifies IP65, the enclosure design and manufacturing process need to account for the interfaces that may allow dust or water to enter.
These may include:
Door and panel joints
Service openings
Cable or equipment penetrations, where applicable
Welded seams
Sealing interfaces
Other openings required by the design
Not every cabinet requires the same sealing arrangement. The correct configuration depends on the product design and the customer's specified test conditions.
For this reason, IP65 should be treated as a system-level requirement for the completed enclosure rather than a claim based solely on the material or coating.
The customer and manufacturer should agree on the relevant acceptance criteria and verification method before production.
Standard cabinets may not meet every parcel locker manufacturer's requirements.
A custom enclosure can be manufactured around the required cabinet dimensions, compartment arrangement, mounting interfaces, door configuration, and finish.
For an equipment manufacturer, this makes it possible to align the metal structure with the overall product architecture.
Our scope is the metal enclosure and sheet metal structural components, rather than the complete parcel locker system.
Depending on the approved design, a project may involve cabinet panels, structural sections, doors, mounting features, and other fabricated sheet metal parts.
The specific scope is established from the customer's drawings, samples, and technical requirements.
To obtain a useful quotation for a custom parcel locker enclosure, equipment manufacturers should provide as much relevant information as possible.
Useful inputs include:
Product drawings: 2D drawings or 3D CAD files showing the cabinet structure and key dimensions.
Material specification: SPCC or another specified material, including thickness where already defined.
Welding requirements: Identification of continuous welds, critical joints, and visible weld areas.
Surface finish: Coating type, color, cosmetic requirements, and any special scratch-resistance criteria.
Protection requirements: The required IP rating and applicable verification criteria.
Assembly interfaces: Door openings, lock positions, mounting points, and other features that affect component fit.
Order quantity: Prototype, initial production, or repeat production requirements.
Providing these details helps establish the manufacturing scope and identify potential issues before production begins.
A parcel locker cabinet needs to meet structural, functional, and appearance requirements as one integrated assembly.
For this project, the key requirements included SPCC sheet steel, anti-vandal construction, continuous welding, scratch-resistant finishing, and IP65 protection.
The important manufacturing consideration is how these requirements interact across the complete cabinet structure.
Panel geometry affects assembly. Welding affects dimensional stability. Surface preparation affects appearance. Openings and interfaces affect the specified protection level.
Addressing these factors together helps equipment manufacturers develop a more manufacturable enclosure around their product design.

The project specified SPCC sheet steel.
Continuous welding was one of the project's structural requirements.
Yes. IP65 was specified for the project, with the enclosure interfaces needing to be considered as part of the overall protection arrangement.
The cabinet structure, panel connections, door interfaces, and any required reinforcement should be designed around the intended application and customer requirements. The actual level of resistance depends on the approved design and validation criteria.
Careful handling, appropriate protection of visible surfaces, controlled fabrication, and clearly defined finishing and inspection requirements can help reduce surface damage.
Our scope is custom metal enclosures and sheet metal structural components. The complete locker system and its electronic or access-control equipment remain outside the enclosure manufacturing scope unless otherwise agreed.
Drawings or CAD files, material and thickness specifications, welding requirements, surface-finish details, protection requirements, and estimated quantities are useful starting points.
