About PORTA-FAB

PORTA-FAB is a manufacturer of modular in-plant offices and cleanrooms, supplying industrial facilities with pre-engineered, relocatable structures designed for interior use. The product line includes 3-wall and 4-wall unassembled offices, cleanrooms, doors, and light fixtures, all built around a steel frame and panelized wall system. Wall panels are available in steel-covered drywall or vinyl-covered drywall, with exterior color options including beige and gray. All units are rated with a Sound Transmission Coefficient (STC) of 31, providing a measurable level of acoustic isolation suitable for supervisory stations, break rooms, or controlled environments within manufacturing plants. The modular design allows for unassembled delivery, reducing shipping volume and enabling on-site assembly by facility personnel. Cleanroom models, such as the 20 ft x 10 ft x 10 ft unit (SKU 45K947), are constructed with steel walls and provide a 200 sq ft interior area, meeting basic particulate control requirements for light industrial applications. PORTA-FAB structures are not intended for exterior use; they are designed for placement on existing plant floors with standard ceiling heights. 3G Electric stocks 78 SKUs from PORTA-FAB, covering a range of standard sizes from 8 ft x 8 ft to 40 ft x 20 ft, with wall heights of 8 ft or 10 ft. The product offering includes both 3-wall and 4-wall configurations, allowing buyers to select open or fully enclosed layouts. All units are supplied unassembled, with hardware and assembly instructions included. 3G Electric provides global logistics support for PORTA-FAB products, handling export documentation and shipping to industrial sites worldwide. For procurement specialists and plant engineers, PORTA-FAB offers a standardized, repeatable solution for creating enclosed spaces within existing facilities without the need for permanent construction or structural modifications. The STC 31 rating is consistent across all models, providing a predictable acoustic performance for noise reduction in open plant environments. The steel frame construction meets typical industrial durability requirements, and the panelized walls can be painted or finished on-site if needed. PORTA-FAB does not offer custom sizes or non-standard configurations; all units are based on fixed dimensions listed in the catalog. This makes the product line suitable for projects requiring quick deployment of temporary or semi-permanent interior structures with known performance characteristics.
