What is Extended Plywood — Oversize?

Some applications cannot tolerate a horizontal joint: a three-metre wardrobe wall, a truck side panel, a single-piece exhibition wall. Extended plywood is our answer — core veneers are jointed and re-pressed so the finished sheet runs continuously to 6,000 mm long on a 1220 or 1250 mm width.

The core is assembled with scarf or finger joints staggered layer by layer, so no two joints sit above each other. Bending strength across the joint zone stays close to that of the parent sheet, and after finishing, the joint line is invisible under paint or veneer.

Why buyers choose our Extended Plywood — Oversize

Staggered joints, not stacked

Joint quality depends on geometry. We stagger core joints between layers so the panel does not hinge along a single weak line.

Custom lengths without tooling fees

Lengths are set at the assembly stage, so a 3600 mm or 4800 mm sheet costs proportionally — not a special-order premium.

Straightness that survives transport

Long panels are packed on full-length bearers and steel-strapped at close intervals; oversize warp is a packing problem before it is a press problem.

WBP option for outdoor-adjacent use

Vehicle bodies and site-built structures can specify WBP glue for humidity exposure.

Applications

Long wall panelling

Hotel corridors and lobbies in continuous runs.

Vehicle and trailer bodies

Side panels without mid-height joints.

Large formwork

Column and gang forms built from single sheets.

Exhibition and stage builds

One-piece back walls and set elements.

Frequently asked questions

What is the maximum length you can produce?
6000 mm is our standard maximum. Longer panels are possible as project orders — send us the exact length and we will confirm feasibility.
Are joints visible after painting?
No. With primer and two topcoats the joint line does not telegraph, because the core joints are staggered and the face veneers are continuous over them.
Can I mix standard 4×8 ft and extended panels in one container?
Yes. Extended panels are loaded on the bottom layer with full-length bearers, standard sheets above.
Which thickness works best for 6 m spans?
18 mm with WBP glue is the usual choice for vehicle and formwork duty; 12 mm suits interior panelling.
How is extended plywood priced?
By cubic metre like standard plywood, based on the actual extended dimensions. Request a quote with your length list.
