CompletionMachining, finishing, hardware and assembly
Outdoor Performance Starts With the Design
- Material: aluminum, stainless, carbon steel or galvanized sheet selected for the actual environment.
- Water management: seams, roofs, drainage, door structure and cable entries reviewed together.
- Corrosion protection: pretreatment, coating system, cut-edge protection and dissimilar-metal contact considered.
- Thermal design: vents, fans, filters, ducts and cooling interfaces coordinated with the equipment layout.
- Serviceability: removable panels, hinges, locks, lifting points and maintenance access defined from the drawing.
Protection-rating note: An enclosure is not automatically IP-rated because of its material or coating. Gaskets, joints, doors, cable entries, drainage and validation requirements must be defined for the complete design.
From Drawing to Production
Engineering Review
Confirm dimensions, material, loads, mounting, airflow, finish and required quantity.
Prototype & DFM
Review bending, welding, hardware, assembly access and cost-sensitive features.
Sample Verification
Inspect drawing-defined dimensions, fit, appearance and agreed functional points.
Repeat Production
Use the approved revision, inspection criteria, packaging and change control as the production basis.
