Structural steel platforms that double usable floor area. PE-stamped, IBC and OSHA compliant.
Pre-wired, climate-controlled offices installed inside your facility. Move-in ready in weeks.
Modular cleanrooms for pharma, manufacturing, and life sciences. ISO 1-100,000 classes available.
Ballistic-rated guard booths and screening stations engineered to UL-752, NIJ, and STANAG standards.
Sound-attenuating and safety enclosures that isolate equipment for compliance and worker protection.
Modular wall systems that partition active space without permanent construction. Fully relocatable.
Modular (pre-engineered) buildings — mezzanines, in-plant offices, cleanrooms, guard houses, machine enclosures, and demountable walls — are factory-built structures installed inside or beside your existing facility in 2–4 weeks. They add usable space or a controlled environment at a fraction of ground-up construction cost (typically $75–150 per square foot), with PE-stamped engineering, no lengthy permitting, and no production shutdown.
Explore the modular catalogA Reynolds engineer walks your facility, measures clear heights and floor loads, and confirms code constraints.
We produce PE-stamped structural drawings sized to your use case — storage, production, office, or cleanroom.
Components are factory-built to spec while your operation keeps running — no on-site construction trades.
Our crew assembles on site in 2–4 weeks, OSHA/IBC compliant, with no production shutdown.
Compare options to find the best fit for your facility's growth, budget, and timeline.
Same usable square footage — engineered and installed in weeks, for a fraction of a ground-up build, with no production shutdown.
▮ Modular · New construction
Partition, enclose, or reconfigure space in days — not the months a permanent build takes. Demountable systems are fully relocatable, install without heavy structural permitting, and depreciate faster than fixed construction.
Unlock the vertical volume of your facility. Our structural steel mezzanines add usable square footage for storage, production, or office space—without the cost of a new building.

Pre-engineered modular structures typically install for a fraction of ground-up construction, which runs $75-150 per square foot. Because they are factory-built and assembled on site in 2-4 weeks, you avoid extended permitting, general-contractor overhead, and production downtime. Reynolds provides a fixed engineered quote after a site assessment.
Most mezzanine installations are completed in 2-4 weeks. This includes design, engineering, manufacturing, and on-site installation. Complex projects may take 4-6 weeks.
Yes, our modular office systems are designed to be relocatable. If your operations change, the offices can be disassembled and moved to a new location within your facility.
Yes, all our mezzanine designs include PE-stamped structural engineering drawings. This ensures compliance with local building codes and OSHA requirements.
Our structural steel mezzanines support 125-500 PSF (pounds per square foot) depending on your requirements. We design each system for your specific use case—storage, production, or office space.
Reynolds designs, engineers, and installs ten modular building types across PA, NJ, DE, and MD: structural mezzanines, work platforms, catwalks, in-plant offices, cleanrooms, machine enclosures, guard houses, vestibules, shelters, and temporary/demountable walls. Every system is PE-stamped and OSHA/IBC compliant.
