Custom industrial sheet metal fabrication
Custom IP57 Enclosure Fabrication for Industrial Equipment
From design review through production, we manufacture custom enclosures for industrial and OEM applications—including housings designed for brief immersion or temporary flood exposure.
Send us your drawings for a manufacturing review and RFQ.

Understand the requirement
What IP57 means for your project
IP57 is an ingress protection rating under IEC 60529. The first digit, 5, indicates dust protection; the second digit, 7, relates to temporary immersion under specified test conditions. The rating depends on the complete enclosure design and validation—not on the sheet metal shell alone.
Consider the complete assembly
Seams, doors, access panels, cable entries, fasteners and gasket compression can all affect water ingress.
Define exposure conditions
For rainwater pooling or short-term immersion, share expected water depth, exposure time, orientation and operating conditions.
Final IP claims should be confirmed through appropriate testing of the finished assembly. A fabrication description alone does not prove an IP57 rating.
For temporary flood exposure
Welded housings for special engineering pits
Where stormwater may cause short periods of partial submersion, we can fabricate welded sheet metal housings with careful attention to seam continuity and fit-up.
We can work toward continuous, carefully controlled weld seams without visible pinholes, paired with a high-compression sealing flange and a suitable gasket arrangement. The required performance must be specified and verified on the finished enclosure.
Details that work together to help prevent leakage
Welded shell
Seam continuity and fit-up, with process selected for material, thickness, joint design and structural or cosmetic requirements.
Sealing flange
High-compression flange and suitable gasket arrangement, considered alongside flange flatness and door geometry.
Interface details
Fastener spacing, compression stops, cable entries and access-panel design all affect sealing performance.
Verification plan
Agree exposure conditions and acceptance criteria, then validate the finished enclosure using the applicable test method.
Please provide expected water depth, exposure time, orientation, gasket material requirements and any test protocol. A well-welded shell alone cannot prevent leakage if the access interface is poorly designed.
Manufacturing capabilities
A fabrication line under one roof
Our facility handles compact electrical boxes and large machinery housings. Keeping cutting, forming, joining and finishing in-house helps coordinate operations and reduces reliance on outside suppliers for key production steps.
Laser cutting & forming
Three fiber laser cutting machines with 12kW and 6kW sources, plus five CNC press brakes for compact parts, heavy panels and multi-stage bends.
Joining & hardware
Handheld laser, MIG, TIG and cold-welding resources, along with automated insertion and tapping equipment.
Large assemblies
Assembly platforms up to 2000 × 6000 mm support large frames and cabinets; internal handling equipment accommodates heavy assemblies and packed goods.
Finishing
An automated 2500 × 6000 mm powder coating line includes pretreatment, powder application and thermal curing. Stainless steel resources support brushed and satin finishes, weld blending and deburring.
Engineering & quality
Review manufacturability before production
Our five mechanical and manufacturing engineers can review supplied 3D CAD and drawings for bend allowances, forming access, hardware locations, weld access and assembly clearances. This is especially useful for multiple bends, large panels, tight dimensional relationships and door-and-flange interfaces.
We can flag details that may create interference or complicate repeatable fabrication, then discuss practical adjustments with your engineering team. Final design authority remains with the customer unless revisions are specifically approved.
Quality checks across production
Six QA/QC specialists support incoming material verification, in-process checks, first-article review and pre-shipment inspection.
Identify critical-to-function features early:
- Mounting-hole locations and hardware position
- Flange flatness, door alignment and sealing surfaces
- Applicable tolerances, inspection expectations and documentation
Share these requirements in your RFQ so they can be assessed during quotation.
Built around your application
Select construction for the conditions and verification method
We serve industrial equipment builders, energy and power infrastructure suppliers, and field automation integrators. Typical projects include machinery housings, electrical cabinets, battery storage equipment enclosures, inverter and charging equipment housings, and outdoor control cabinets.
Temporary water exposure+
Define depth and duration, then review weld continuity, door or cover interfaces, gasket compression, cable entries and fastener spacing.
Outdoor electrical equipment+
Specify the required ingress protection, coating system, material and any UV or corrosion considerations.
Machinery and production equipment+
Provide panel interfaces, service access, mounting points, ventilation requirements and assembly clearances.
Large cabinets and machine housings+
Share overall dimensions, panel breakdown and lifting or handling requirements so we can assess forming, fixturing and transport.
Our engineers can review manufacturing suitability and raise design questions. Rating requirements and acceptance criteria should be agreed before production and validated using the applicable test method.
