SIMONA; HDPE Boat Board; sets the high bar for its combination of long-term performance, durability, appearance and fabrication ease and consistency.

In boat building components, this tough, UV resistant sheet withstands long term exposure to intense sun, salt water and rigorous use. This also makes it ideal for outdoor patio, poolside and marina cabinetry, furniture and accessories. Its impact resistance, FDA compliance, easy-to-clean surface and attractive appearance enhance indoor medical, clinical and laboratory cabinetry as well.

Unlike plywood, SIMONA HDPE Boat Board won't delaminate, rot or splinter, and its integral colors hide scratches and marring that ruin painted surfaces. Its stain resistance, easy-to-clean matte finish and wide spectrum of integral colors further assure long lasting appearance and functionality.

In fabrication, it maintains exceptional flatness and dimensional stability for high production yields and finished part quality. Standard woodworking equipment works well with the material, and fabricators appreciate its advantages especially in thicker gauges for large flat, formed or machined panels.

    1/2" boat board

    Got my order quickly (USA to Canada). Well packaged and looks great. Ideal for my custom marine project. Local plastic suppliers could not even come close to this price. All they wanted to do was sell me a full sheet for an outrageous price! This will be my 'go to' source for future plastic purchases.
