Aging ironwork? No, it’s MDF for outdoor use

In Issue02, WoodTECH by FIEALeave a Comment

Large scale installations by Alexander Devereux for a sculptural park in the North East of England, inspired by famous bridges in the region, were fabricated from Tricoya, a specialized MDF for outdoor use.

Devereux used Tricoya MDF on several projects. Tricoya MDF has an outdoor useful life of 50 years, owing to its treatment with the acetylation process. Mounted outdoors as well as indoors, Devereux’s works can be seen at England’s Cheesburn Sculpture Park’s permanent collection; and at Broomhill Sculpture Park in North Devon.

To get the aging metal effect, Devereaux slathered plaster and iron powder onto the Tricoya. A hinge detail measuring 3.5m x 3.5m x 1.5m at shows the stunning effect. Devereux modeled the pieces after the original 19th century ironwork, drawing inspiration from the rivet patterns, which were both utilitarian, and decorative.

Tricoya is manufactured by Irish forest products firm Coilte, in its Medite unit, in partnership with BP – which makes the chemistry used in aceylation – and Accys Technologies, which produces Accoya solid wood made from radiata pine and other lumber using the acetylation process.

Tricoya MDF panels ( are made using wood chips that receive the acetylation process before milling into panel. They are lightweight, sustainable and offer a 50 year above ground and 25 year in ground guarantee, revolutionizing the opportunities presented to architects, specifiers, designers and home owners the company says. Tricoya was launched to the U.S. market at the 2017 AWFS Fair in Las Vegas.
