Plywood

Plywood is a sheet material manufactured from thin layers or "plies" of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another.

Available thicknesses and colors

• 6mm - Birch - INT glue - B/BB
• 4mm - Birch - INT glue - B/BB
• 3mm - Birch - INT glue - B/BB

• 3mm - Birch - WBP glue - Aircraft grade
• 2mm - Birch - WBP glue - Aircraft grade
• 1.5mm - Birch - WBP glue - Aircraft grade
• 1mm - Birch - WBP glue - Aircraft grade

• 0.8mm - Birch - WBP glue - Aircraft grade
• 0.4mm - Birch - WBP glue - Aircraft grade

• 4mm - Fir

Glue types:

INT: for indoor use.

WBP: Water and boil proof, for outdoor use.

Quality:

Aircraft grade - Highest quality AB/B. Aircraft grade uses thinner plies than other plywood, making this quality the strongest.

B/BB - Top side: Few branches allowed, maximum size 6mm. Minimum discoloration. Bottom side: Branches allowed, maximum size 25mm. Varied color allowed.

S/BB - Top side: Few branches allowed, maximum size 20mm. Some discoloration allowed. Bottom side: Branches allowed, maximum size 25mm. Varied color allowed.

Cut width

~ 0.08-0.25mm

Sheet Size

• ≥ 1mm: 1200mm * 750mm
• <1mm: 994mm * 194mm

Hints from TechStation!

Keep in mind that plywood sheets aren't always totally flat.

Benefits:

+ Good mechanical properties

+ Simple to glue

Drawbacks:

- Sheets are not always totally flat

- Cut edges turn to carbon and may stain

Mechanical properties:

• Density: 500-700 kg/m³
