Plywood is the product of choice for architects, engineers and contractors when it comes to concrete forming. Its many advantages include a high strength/weight ratio, versatility, design freedom and low cost per use.
Formall® is a registered trademark of TECO that is applied to concrete form plywood panels manufactured in conformance with the requirements of the U.S. Department of Commerce Voluntary Product Standard PS 1, Structural Plywood. PS 1 establishes minimum requirements for the principle types and grades of construction and industrial plywood including wood species, veneer grading, glue bond, panel construction and workmanship, dimensions and tolerances, marking, moisture content, quality control and certification.
Formall meets the requirements for an “Exterior” bond classification and is manufactured with “B” face and back veneers and “C” or better inner plies. Bond classification is related to the moisture resistance of the glue bond under intended end-use conditions and does not relate to the physical (erosion, ultraviolet, etc) or biological (mold, fungal decay, insect, etc) resistance of the panel. Formall, with its Exterior bond classification, is suitable for repeated wetting and redrying or long-term exposure to weather or other conditions of similar severity.
Formall is a Class 1 concrete form plywood designed to provide superior performance in the most demanding applications. A Class 1 panel, as defined in PS 1, is a panel with a Group 1 species in the face veneers, Group 1 or Group 2 species in the crossbands and Group 1, 2, 3, or 4 species in the center plies. A Group number is used to classify species covered by PS 1. Numbers range from 1 to 5. Strength and stiffness properties of species in Group 1 are typically highest, while the strength and stiffness properties of species in Group 5 are the lowest.
Formall concrete form plywood performs ably and economically in heavy or light construction applications. Formall provides surfaces with an acceptable finish that minimizes surface roughness and blemishes. Formall can also be manufactured with a high density overlay when smoothness and surface quality are of the utmost importance or special effects such as texturing are required.
Non-overlaid Formall is typically available with sanded faces, ends and edges sealed and faces mill oiled unless otherwise specified. Standard thicknesses include 19/32”, 5/8”, 23/32” and 3/4” in standard 4’ x 8’ sheets. Contact the manufacturer for availability.
