Technical FAQ

Review critical engineering considerations, international safety codes, material tolerances, and manufacturing workflows for custom industrial metal enclosures.

Our engineering team sizes secondary containment sumps to align with EPA 40 CFR 264.175 and NFPA 30 guidelines. The sump capacity is designed to contain at least 100% of the single largest storage vessel or 25% of the aggregate total volume of all stored chemical containers, whichever is greater. We precision-bend heavy-gauge 304 or 316 stainless steel or carbon steel with seamless liquid-tight TIG welding and conduct helium leak testing to help ensure reliable containment integrity.
