Durable Concrete Forming Plywood

Concrete forming products, including generic BB Plyform, overlaid resin film plywood, MDO and HDO concrete form panels.BB Plyform, MDO and HDO concrete form panels manufactured from veneers for use as concrete form are required to be qualified for glue bond durability and structural capability and include Class I, Structural I or other related designations.

The factory manufactures concrete form or overlay plywood with a coated surface.  The factory bonds the overlay surface to both sides of the board with heat and pressure.  The mills construct the concrete forming plywood with 100 percent moisture resistant glue.

The tough overlay with stands severe exposure without further finishing. It also resists abrasion, moisture penetration and deterioration from many common chemicals and solvents.

Allows up to 20 reuses (requires reasonable care). Overlaid with dark brown film. Recommended for concrete that requires further treatment such as painted, or other coating treatments. These plywood are High strength and light weight, with phenolic resin.

The panels panels are edge sealed during manufacturing. If you cut boards during the use, it is recommended to re-seal the fresh edges to avoid panel damage caused by capillary penetration of humidity.

Demanding applications such as concrete forming, exterior siding, and industrial containers require tough building materials. High and Medium Density Overlay plywood (HDO and MDO) combine the toughness of Exterior-type plywood with the superior wear of an overlaid surface. These features place HDO and MDO among the most durable construction materials on the market today.

HDO and MDO feature highly durable, resin-impregnated fiber faces. The thermoset resin, bonded under heat and pressure, forms a very tough surface that easily resists abrasion, moisture penetration, chemicals, and deterioration. HDO is manufactured with more resin than MDO, but both are far more durable than standard plywood and are ideal for use in the most punishing of applications. Yet they retain plywood's advantages, such as high strength to weight ratio, dimensional stability, and rack resistance, as well as plywood's design flexibility; panels are available in large sizes and can be worked with common woodworking tools.

HDO is available in two grades, Concrete Form and Industrial, and MDO is available in Concrete Form and General grades. Concrete forming grades are both ideal for reuse under the harsh conditions of concrete formwork; HDO leaves a smooth "steel-form" finish while MDO leaves a matte finish. Both may be reused for concrete forming many times, but HDO has a longer use life. Industrial grade HDO panels are commonly used for highway panels, industrial tanks, and other highly demanding applications. General grade MDO is manufactured to be an ideal paint base and is used for structural siding, soffits, and other exterior applications where long-lasting paint or coating performance is required.

Medium Density Overlay (MDO) Sign grade plywood is designed to meet the highest standards to meet applications for “paint-grade” applications, both for indoor and outdoor applications. This includes billboards, highway signs, office signs, soffits, siding, facia, cabinet liners, partitions, casework, modular furniture, and more.These MDO Sign grade panels are highly resistant to weathering , delamination and also deliver the structural properties required for large sign installations.
