Pine Blockboard

Pine finger-jointed core with HDF or plywood face — structural stability for furniture frames and construction applications.

Pine blockboard combines small pine finger-jointed strips (core blocks) sandwiched between two layers of HDF or plywood veneer. The result is a flat, lightweight, screw-holding panel with excellent dimensional stability — superior to solid pine for large formats. Available in Fromager (French grade) and EV (moisture-resistant) grades.

Available Grades

Three Blockboard Grades

Each grade serves different market requirements. We match grade to your end use and destination market.

Standard Blockboard

Fromager Grade

EV Moisture Resistant

Pine FJ Core

Pine finger-jointed strips, grade G4/G5. Kiln-dried to 10–12% moisture. Blocks 20–40mm wide.

HDF or Plywood Face

2.5–3mm HDF or BB/CC plywood face on both sides. Smooth surface ready for veneer, paint or laminate.

15–50mm Thickness

From 15mm (door cores) to 50mm (structural panels). Standard: 18, 22, 25, 30, 38mm.

French Export Grade

Manufactured to French GFF (Groupe France Finitions) standards. Strict tolerance on surface defects, flatness deviation under 2mm/m.

Visual Inspection

Each panel visually graded under 1 lux light. No open joints, no delamination, no core gaps. Same-face matching within batch.

Giachetta Approved

Fromager-grade panels meet Giachetta Legnami specifications. Available with Giachetta专属标签 for batch identification.

Enhanced Water Resistance

EV (E-Verbond) adhesive: melamine urea-formaldehyde with enhanced moisture resistance. Suitable for humid environments.

Middle East Climate

Designed for high humidity during sea transit and variable humidity in Middle East storage. Reduced swelling at edges.

Recoatable

Accepts paint, lacquer and wood veneer after light sand (120-grit). Edge sealing recommended for exterior-adjacent use.

Strong Screw Holding

Core density 450–550 kg/m³. Edge screw withdrawal resistance above 80 N/mm — suitable for hardware fitting.

Light Weight

Density 480–580 kg/m³ — 20–30% lighter than plywood of equivalent thickness. Reduces shipping cost.

Clean Edge

Solid pine edge accepts Joinery cutting, dowelling and metal connector plates. No hollow core voids.

Custom Block Width

Block width can be adjusted: narrow (20mm) for painted finish, wide (40mm) for natural veneer or structural use.

Applications

Where Pine Blockboard is Used

Furniture Frames

Door cores, table tops, cabinet frames. Light yet rigid. Preferred over solid wood for large formats.

Upholstered Furniture

Sofa frames, bed frames, seating bases. Cost-effective structural substrate.

Interior Construction

Partition walls, ceiling panels, display structures. Flat and easy to install.

Packaging Cases

Re-usable industrial crates, machine guarding. ISPM15 heat-treated for export.

Transport Flooring

Truck body floors, trailer side walls. MR/EV grade recommended for this use.

CNC Profiling

Cut-to-size, drilled, grooved. Clean routed edges for joinery and fixtures.

Common Questions

FAQ

What's the difference between blockboard and plywood?

Blockboard has a core of finger-jointed wood strips (blocks), lighter and more dimensionally stable than solid wood but less strong than plywood in cross-load. Plywood has cross-bonded veneers throughout. Blockboard is preferred for large flat panels where weight saving matters; plywood for structural or humid applications.

Fromager grade vs standard — what's the actual difference?

Fromager (French grade) has tighter tolerances: flatness deviation under 2mm/m vs 3mm/m standard, stricter visual grading (no open joints visible under 1 lux), and batch face-matching. Surface is suitable for clear lacquer without putty. Essential for French and Italian premium furniture buyers.

What happened with the EV panels and glue penetration?

March 2026 batch had insufficient glue spread rate on the EV adhesive line, causing edge penetration issues in some panels. Root cause: adhesive roller wear below tolerance. New production protocol: monthly roller inspection, glue spread rate check every shift, mandatory edge hardness test before dispatch. Replacement batch confirmed available.

Can you produce with custom block widths?

Yes. Standard block width is 25–30mm. For painted finishes we can use 20mm (finer surface). For structural use 40–50mm blocks for maximum stability. Lead time for custom block width: +5 days. MOQ applies.

Lead time for 2×40HQ mixed order?

Standard: 18–25 days. Mixed grades (Standard + Fromager + EV): 22–30 days. Includes mill run selection, quality inspection and export packing. Exact date confirmed at order confirmation.
