Hardboard

Welde hardboard PACKAGING

Welde hardboards are glue-free thin boards that are formed using high pressure and high temperature during a wet process.

Hardboard

The unique wet process creates a fibreboard that stands for fresh wood, natural resins and energy from renewable sources. This combination guarantees a healthy and responsible material from production to use. Its disposal is also absolutely safe. Hardboard therefore represents boards in the cycle of nature.

Hardboard PACKAGING

Welde packaging is a board that is used to protect goods or different substrates. The most important features are the high impact strength and tear resistance. There are no special requirements to bending strength or swelling behavior.

Our PACKAGING board

Our packaging panel is mostly used in flat applications. For example: as a cover on pallets, sheet metal layer or to cover floors on construction sites.

Hardboard TOP

Welde hardboard TOP is a board that utilizes improved technical features such as lower water absorption and higher bending strength. Due to the special wood mixture, the board is particularly light in color and the surface is easy to paint.

Our TOP Board

Our TOP board can be found in applications with special requirements, such as in the automotive industry as a door skin, or as an intermediate layer for glass bottles.

Hardboard STANDARD

Welde STANDARD hardboards are general purpose boards for use in dry environments (Type HB) according to EN622-2.

The panels have good bending strength and a smooth surface.

Our STANDARD board

Our STANDARD board is known as the classic hardboard. Universally applicable in dry areas, particularly popular in furniture construction. It is also available in a lacquered version.

Hardboard Flex

Welde FLEX hardboards are, as the name suggests, flexible. These hardboards are an internal development and are unique due to their wood mixture and the moisture management in the board.

Our FLEX board

Our FLEX board is primarily used in the sofa industry for armrests and in the steel industry for packaging  steel coils. The board must be able to bend around tight radii.
