Mezzanine flooring overview banner



At Cornerstone Specialty Wood Products, we understand that flooring needs can be complex, and there may be a variety of demands within a single project. We offer multiple flooring options that are customized for load capacities, required finish type, volume and type of traffic including heavy rolling pallet jack loads and robotic traffic with AGVs and AMRs.

ResinDek flooring panels have been independently evaluated and approved for use in Types I-V construction and as part of a fire-resistance rated assembly by the IAPMO Uniform Evaluation Services. All ResinDek panels are certified to have No Added Formaldehyde and can contribute towards earning points for LEED® qualified buildings. When required ResinDek panels are available with FSC® Certification. FSC® License Code FSC-C124474.

ResinDek composite engineered flooring panels are customed manufactured and available in sizes up to 4' x 10' (1220 mm x 3048 mm). Each panel features a tongue-and-groove configuration that effectively promotes panel to panel wheel load transfer. When required, tongue-and-groove configurations are available on all 4 sides. ResinDek panels have the durability and structural integrity to support live and dead rolling pack jack loads from 2,000 to 8,000 lbs. and mobile robots from 500 to 6,000 lbs.

Cornerstone Specialty Wood Products can provide a hybrid flooring solution that is extremely cost-effective and is tailored to meet the needs of each individual project. ResinDek panels are backed by comprehensive design engineering services and a 10-year product warranty.

  • For flooring used with corrugated B Deck: Please note load values above are calculated on 36" beam spacing, increased spacing will reduce capacity. Floor deflection is L/240
  • For flooring solutions with no B Deck: All allowable loads are based on a two span condition. Uniform load values are based on L/240 deflections, any deviation can positively or negatively impact these values. Please contact Cornerstone for other span conditions.
