Plymetal Swing Door Panels
Plymetal swing door panels are an excellent choice for most trailer/van body door applications. There are numerous panel thickness and facing options, all of which provide strength and durability.
- The inner core is made from exterior grade Douglas Fir plywood as standard. Oriented strand board (OSB) and other wood-based cores are available to suit your requirements; for example, where a lightweight core is required.
- The patented urethane-type adhesive we use provides a superior bond and meets all transportation specifications.
- We offer a wide range of panel faces, including:
- Galvan® High- Tensile Steel (pre-painted or mill finish) for an extremely durable facing that can withstand an immense amount of force before breaking
- Galvanized Steel (pre-painted or mill finish) for extra protection against corrosion and rusting, ideal for shipping or other water-related applications
- Aluminum (pre-painted or mill finish) 3003-14, 3105-H14, 5052-H34 for a lightweight yet puncture-resistant facing
- Stainless Steel (SBA or mill) 304-2B for high corrosion and rust resistance where water is not a concern
- 1/2″ Composite Panels (polyethylene core with white steel facing), extremely durable and are recommended for applications where weight is not a concern.
Plate-LOK Doors
Plate-LOK doors are the best choice for applications that are temperature sensitive and require insulation, such as foodstuffs or beverages. The galvanized steel exterior gives a tough and puncture-resistant finish, while the white-baked polyester finish is an ideal surface for graphics and decals. Other colours are available for quantity production runs.
- The inner structural core is created from a high-density foamed polyethylene (PE). The thermal bonding process we use adheres the core to the external skins and is the industry standard for transportation plate sidewall and door products.
- The panel faces are 80,000-psi yield galvanized steel with a standard white-baked polyester finish.
