304 or 316: Select for the Environment

Grade	Selection Consideration	What to Confirm
304	A common choice for many general industrial housings where the exposure conditions are compatible with this grade.	Indoor or outdoor location, moisture, cleaning products and surface appearance.
316	Molybdenum improves resistance to localized chloride corrosion, making this grade worth evaluating for more demanding exposure.	Salt exposure, chemical contact, operating temperature and maintenance conditions.

Grade selection, fabrication quality, surface condition and cleaning practices all contribute to corrosion performance.

Specify the Complete Enclosure

Size & Thickness: Define external dimensions, usable internal space and mounting loads. Wall thickness is reviewed against enclosure size, stiffness and forming requirements.
Door & Sealing: Confirm door access, hinge arrangement, latch positions, gasket details and sealing surfaces.
Cutouts & Mounting: Specify cable entries, display or control openings, gland plates, mounting plates and brackets. Include grounding connection positions where required.
Surface Finish: Brushed stainless steel, mirror polishing or powder coating can be reviewed to suit appearance and service conditions. Specify visible faces and grain direction.

Planning for IP65 Protection

IP65 means dust-tight protection and protection against water jets under specified test conditions. It does not establish protection for immersion.

The complete enclosure configuration matters: doors, seals, welds, windows and cable-entry components must be considered together. Please specify any required ingress testing and documentation so the scope can be agreed during quotation.

From Technical Review to Finished Housing

01 / Drawing Review

Send STEP/STP, IGES/IGS, PDF or DWG/DXF files. We review the grade, enclosure layout, fabrication details and critical interfaces. Sketches can start an initial discussion.

02 / Fabrication

Cutting, bending, welding and finishing follow the agreed drawing. Prototype quantities and repeat production can be planned around your project.

03 / Inspection & Delivery

Dimensions, fit and appearance are checked against agreed requirements. Confirm any additional testing, reports, packaging and delivery needs before production.
