Portafab Launches Advanced Mezzanine Flooring for Industrial Office Use

Are you facing challenges with insufficient storage space or looking to efficiently expand office areas within existing facilities? In today's land-scarce environment, the strategic utilization of vertical space through mezzanine floors offers a practical solution to multiply usable area without expanding footprints.

For most warehouse and office applications, standard mezzanine flooring provides an optimal balance of performance and affordability. This system consists of two primary components:

• Base Layer: 1-1/2 inch (approximately 3.8 cm) galvanized corrugated steel decking that provides structural integrity while the white underside enhances light reflection, improving illumination and reducing energy costs.
• Surface Layer: 3/4 inch (approximately 1.9 cm) OSB (oriented strand board) that offers excellent wear resistance and impact absorption, capable of supporting up to 300 lbs (136 kg) of random wheel loads.

This combination delivers reliable performance for light industrial use while maintaining cost efficiency.

For applications requiring enhanced ventilation, light penetration, or fire safety compliance (allowing sprinkler water passage), steel bar grating presents an excellent alternative:

• 1 inch x 1/8 inch (approximately 2.5 cm x 0.3 cm) steel grating provides superior airflow and light transmission
• Available with standard black rust-preventive paint or optional galvanized finish for corrosion resistance
• Offers economic and environmental benefits through material efficiency and recyclability

Note: Due to its open grid structure, bar grating is not recommended for pallet jack applications.

For applications requiring higher point loads or increased durability, steel tread plate configurations provide superior performance:

• Option 1: Diamond-pattern steel tread plate installed over OSB substrate combines the structural benefits of OSB with enhanced surface durability
• Option 2: Steel tread plate directly over 20-gauge steel decking provides a completely non-combustible solution for strict fire code compliance

For environments with frequent pallet jack or cart traffic, or where superior cleanliness is required:

• Engineered to withstand concentrated heavy loads
• Features Acryseal-coated surface for slip resistance and easy cleaning
• Provides seamless, joint-free surface for smooth equipment operation
• Available in standard gray or custom colors

For the most demanding applications requiring ultimate load capacity and longevity:

• Superior compressive strength for extreme point loads
• Excellent sound insulation between levels
• Exceptionally long service life with minimal maintenance

Structural steel components are provided to support concrete placement, creating a permanent, heavy-duty mezzanine solution.
