Ex proof junction boxes and control panels for hazardous locations
We build explosion-proof junction boxes and control panels for hazardous locations, custom-made for your project: the enclosure with a bolted flange and, if you need it, your control equipment mounted inside.
- Junction boxes for splices and taps
- One- or two-door panels with mounting panel, push buttons, selector switches, pilot lights and viewing window
- Painted carbon steel (also in safety orange) or 304 / 316L stainless steel
- NPT or metric threaded entries, in the number and on the face you specify
- Identification and warning nameplates with your text
The area classification (class, division and group) is defined by your engineering: with it in the request, we quote on the correct specification. Every piece is tested at our plant in San Juan del Río, Querétaro, before it ships.

Frequently asked questions
What do I need to request a quote?
Approximate dimensions, material and quantity are enough to start. If you have a drawing, attach it as a PDF; if not, mark it as “Not yet” and an engineer will call you.
Who defines the area classification?
You or your engineering team specify it, based on where it will be installed. We build the enclosure to that specification.
What tests are done before it ships?
Hydrostatic and pneumatic testing per ASME Section VIII, Div. 1, and liquid penetrant inspection.
Do you build it in 316L stainless steel?
Yes: painted carbon steel, 304 or 316L stainless steel.
Do you invoice and ship throughout Mexico?
Yes, with a CFDI invoice. Large items go by freight, quoted with your order, or you can pick up at our plant in San Juan del Río.
