McIver Engineering makes electrical and control enclosures, cabinets, door panels and chassis to your drawing at our Smithfield workshop. Mild steel and galvanised sheet for powder coated cabinets, 304 and 316 stainless steel TIG welded and dressed for wash down and food processing plants, from a single prototype to repeat batches.
Send DXF, DWG, STEP or PDF files, or bring the existing cabinet or a sample to Smithfield and we will measure it and produce the flat patterns. Every cutout for a gland, a display, a switch or a vent is cut on the laser in the same operation as the blank, so a layout change is a file change rather than new tooling, and the holes land where the drawing says.
Blanks are folded on our own floor. Heavier plate and unusually long folds go to a press brake subcontractor we have used for years and are managed by us under the same purchase order. Mild steel cabinets are MIG welded; stainless enclosures are TIG welded, with back purging where the inside of the joint has to stay clean, then dressed and passivated so there is no crevice or heat tint left to harbour product.
Every enclosure is checked back to the drawing after welding, because distortion is what puts a door out of square. Weld dressing, linishing and deburring are done in house, and powder coating is arranged with finishers we have used for years and stays on the same purchase order.
Mild steel, powder coated, is the default for indoor switchrooms and plant rooms, and galvanised or zinc anneal sheet where a coating is wanted straight off the machine. 304 stainless is the choice for general wash down, and 316 where chlorides, coastal air or wash down chemicals are involved. Stainless is kept separate from carbon steel work, with dedicated consumables and abrasives, so a food grade enclosure stays clean.
Where a sealed enclosure, a specific ingress rating or a standard is called up on your drawing, raise it at enquiry stage. We fabricate to the drawing and will confirm what we can make to it before quoting, rather than discover it at handover.
One off enclosures and replacement doors are everyday work and there is no minimum order. Up to about five parts takes two to three weeks, fifty to one hundred takes four to six weeks, and every quote confirms the lead time. Repeat orders can be held to an agreed schedule so unit pricing stays stable.
For repeat production quantities of enclosures that do not need to be made in Sydney, our sister business Global Supply Network sources sheet metal fabrication overseas with engineering oversight from the same group.
Yes. 304 and 316 stainless enclosures are TIG welded with back purging where needed, then dressed and passivated so the seams are clean for wash down. Stainless is kept separate from carbon steel work.
Yes. Every cutout is laser cut in the same operation as the blank from your DXF or layout, so the holes land where the drawing says and a layout change is a file change.
Yes. Bring the door or the cabinet to Smithfield, or send photos with the dimensions, and we will measure it and quote. There is no minimum order.
We fabricate, weld and finish the enclosure to your drawing. Tell us at enquiry stage what hardware, gaskets or fittings the job needs so it is priced from the start.
Up to about five parts takes two to three weeks and fifty to one hundred takes four to six weeks. Every quote confirms the lead time, and rush work is taken on where the floor allows.
