Square Box Custom Electrical Enclosures
Square Box industrial enclosure manufacturing
Basic Capability Table
Exact material, thickness, finish, tolerance, inspection and assembly scope should be confirmed from drawings, BOMs and project requirements.
| Materials | Carbon steel, galvanized steel, 304 stainless steel, 316 stainless steel, aluminum and project-specified sheet metals. |
|---|---|
| Typical thickness | Common enclosure work is project-dependent by size, structure, rating target, mounting method and customer drawing; thickness is confirmed during RFQ. |
| File formats | STEP, STP, SLDPRT, SLDASM, DXF, DWG, PDF, ZIP, RAR and marked product photos. |
| Fabrication scope | Laser cutting, CNC punching, bending, forming, welding, grinding, deburring, cutouts, doors, plates, covers and cabinet structures. |
| Finish options | Powder coating, brushed stainless, raw/unfinished parts, plated hardware areas and project-confirmed masking requirements. |
| Assembly scope | Mounting plates, DIN rail, wire duct, terminal blocks, grounding hardware, labels, cable glands, fans, filters and customer-approved BOM items. |
| Inspection support | Inspection photos, critical feature checks, dimension photos, finish checks and packing photos can be requested before shipment. |
| Prototype support | Prototype and low-volume support available after drawing review, specification confirmation and quote acceptance. |
Custom enclosure bodies, doors, covers, brackets, mounting plates and cabinet parts are produced from approved CAD and PDF drawings.
| RFQ detail | Material, thickness, bend allowance, hole pattern, cosmetic surface and assembly notes should be defined before fabrication. |
|---|---|
| Best files | STEP, DXF/DWG, PDF drawing package and assembly notes. |
Laser cutting supports blank profiles, doors, gland plates and custom cutouts. CNC punching supports repeated hole patterns, vents, knockouts and panel features.
| RFQ detail | Best RFQs include DXF/DWG flat files, STEP models and a marked PDF showing critical cutouts. |
|---|---|
| Best files | STEP, DXF/DWG, PDF drawing package and assembly notes. |
Boxes, flanges, doors, rain hoods, brackets, base channels and returns are formed to the approved drawing.
| RFQ detail | Bend radius, grain direction, finish face and tolerance-critical dimensions should be marked when they matter. |
|---|---|
| Best files | STEP, DXF/DWG, PDF drawing package and assembly notes. |
Frames, seams, hinges, studs, support rails and cabinet structures can be welded, ground and cleaned to the specified cosmetic level.
| RFQ detail | Weld locations, visible surfaces, grinding expectations and inspection points should be called out in the drawing package. |
|---|---|
| Best files | STEP, DXF/DWG, PDF drawing package and assembly notes. |
Powder coating can be quoted with color, gloss, texture, masking, grounding contact areas and packaging protection requirements.
| RFQ detail | Outdoor or corrosion expectations should be stated clearly. Final NEMA/IP rating depends on design, materials and testing requirements. |
|---|---|
| Best files | STEP, DXF/DWG, PDF drawing package and assembly notes. |
Gaskets, locks, hinges, grounding studs, PEM hardware, DIN rails, mounting plates and labels can be installed before shipment.
| RFQ detail | Confirm hardware models, gasket material, sealing path, torque needs and any customer-supplied parts during RFQ. |
|---|---|
| Best files | STEP, DXF/DWG, PDF drawing package and assembly notes. |
Engineering review checks manufacturability, bend feasibility, cutout conflicts, hardware fit and drawing completeness before quoting or fabrication.
| RFQ detail | Square Box can raise questions and recommend fabrication adjustments, but customer approval is required before prototype production. |
|---|---|
| Best files | STEP, DXF/DWG, PDF drawing package and assembly notes. |
Samples and low-volume batches can be packed for express door-to-door or DDP delivery options.
| RFQ detail | Delivery timing depends on dispatch date, courier service, customs clearance and destination. Tariff treatment should be reviewed by the importer’s customs broker. |
|---|---|
| Best files | STEP, DXF/DWG, PDF drawing package and assembly notes. |
Finished samples are checked against the approved drawing, confirmed manufacturing specification and visible finish requirements before packing.
| RFQ detail | Inspection can include dimensions, hole locations, coating appearance, hardware installation, gasket fit and packing condition. |
