Construction plywood from Vietnam splits into three distinct product families — and ordering the wrong one costs you money. Formwork buyers specify film-faced with phenolic WBP. Scaffolding contractors want anti-slip wire-mesh surface. Flooring substrate buyers need high-density eucalyptus core. Each has a different film, glue, core species, and price point.
This guide breaks down all three types with factory-level specs, so you can write a technically accurate purchase order the first time.
🏗️ What Is Construction Plywood?
Construction plywood refers to structural-grade panels engineered for on-site loading conditions: wet concrete pressure, foot traffic on scaffold decks, and subfloor loads. These panels are not sanded, not emission-controlled to E0, and not designed for furniture aesthetics. They are built for mechanical performance and reusability under harsh conditions.
Three types dominate Vietnam’s construction plywood export:
| Type | Surface | Core | Glue | Primary Use |
|---|---|---|---|---|
| Film-Faced Plywood | Phenolic or melamine film | Acacia or Eucalyptus | Phenolic WBP | Concrete formwork, shuttering |
| Anti-Slip Plywood | AICA wire-mesh film 220gsm | Acacia or Eucalyptus | Phenolic WBP | Scaffolding decks, truck floors, walkways |
| Flooring Substrate | Unsanded eucalyptus face | Eucalyptus (full) | Phenolic WBP or MR | Structural subfloor, flooring underlay |
The key shared specification across all three: phenolic WBP glue. This is non-negotiable for wet-environment construction use. Melamine (MR) glue passes a 12-hour boil test; phenolic WBP passes a 72-hour boil test — the difference is critical when panels sit under poured concrete for 7–14 days before stripping (BS EN 314-2, Class 3).
🎬 Film-Faced Formwork Plywood — The Core Product
Film-faced plywood is Vietnam’s most exported construction grade. The panels are covered on both faces with resin-impregnated paper — phenolic on the working face, melamine on the reverse — then bonded to a structural core under heat and pressure.
📌 Film Types: Premium vs Budget
The film is where the quality split happens. Two market-level products exist:
Premium (Export-Grade):
- Film: AICA (Japan) 135gsm minimum, typically 160–200gsm
- Surface hardness: resists abrasion and concrete adhesion
- Edge sealing: factory-sealed with phenolic paint
- Reuse potential: 15–20 cycles (HCPLY production data, 2026)
Budget (Domestic/Southeast Asia):
- Film: Vietnamese or Chinese film, 100–120gsm
- Lower surface hardness, higher concrete bond risk
- Edges often unsealed
- Reuse potential: 4–8 cycles only
The practical implication: a premium panel at $32–38 USD/sheet amortized over 18 pours costs $1.78–2.11/pour. A budget panel at $18–22 USD amortized over 6 pours costs $3.00–3.67/pour. Premium grade is cheaper per use on projects with 10+ pours (HCPLY internal pricing model, 2026).
📌 Core Species for Formwork
Formwork plywood carries concrete pressure during pours — typically 24–48 kPa for standard wall forms, higher for column work. Core density directly determines bending stiffness.
| Core | Density | Recommended for |
|---|---|---|
| Eucalyptus | 650–750 kg/m³ | Heavy-load column formwork, high-rise slabs |
| Acacia | ~580 kg/m³ | Standard wall and slab formwork |
| Styrax | 480–500 kg/m³ | Not recommended for formwork — insufficient stiffness |
⚠️ Important: Styrax core is widely used in furniture plywood but should never be specified for concrete formwork. The lower density means higher deflection under concrete pressure, leading to wavy concrete surfaces and premature panel failure.
Standard formwork thickness: 12mm (light walls), 15mm (standard slabs), 18mm (heavy columns and beams), 21mm (high-load industrial). Most export orders specify 18mm with eucalyptus or acacia core.

🦺 Anti-Slip Construction Plywood — Scaffolding & Transport Grade
Anti-slip plywood uses the same phenolic WBP bonding as formwork grade, but the face film is different. Instead of smooth phenolic, the working face carries an AICA wire-mesh film at 220gsm — the wire mesh is laminated into the film layer during hot-pressing, creating a permanent raised texture.
Applications:
- Scaffold deck boards (walking surface on frame scaffolding)
- Truck and trailer loading floors
- Construction vehicle platforms
- Temporary pedestrian walkways on site
- Crane outrigger pads
Standard specifications:
| Spec | Value |
|---|---|
| Film | AICA anti-slip 220gsm, wire-mesh surface |
| Core | Acacia or Eucalyptus |
| Glue | Phenolic WBP |
| Thickness | 12–21mm (12mm and 15mm most common for scaffolding) |
| Size | 1220×2440mm or 1250×2500mm |
| Reverse face | Smooth film or plain phenolic |
Key Insight: Anti-slip plywood and film-faced formwork plywood share the same structural core and WBP bonding. The only difference is the surface film. Many buyers successfully use anti-slip plywood for formwork applications where the textured face is not an issue — though smooth film-faced is preferred where a clean concrete finish is specified.
The slip resistance of 220gsm wire-mesh film meets safety requirements for occupational working platforms in most markets. European construction sites referencing EN 13374 Class B (inclined walking surfaces) specify anti-slip coefficient ≥0.3, which wire-mesh plywood surface satisfies (HCPLY production data, 2026).

🪵 Flooring-Grade Construction Plywood — Structural Subfloor
Flooring-grade construction plywood is the least discussed but high-volume segment for markets with timber-frame and light-steel-frame construction. Unlike formwork or anti-slip panels, flooring substrate does not carry a specialty film. It relies on the density and stability of the core itself.
Key differences from formwork plywood:
| Property | Formwork Plywood | Flooring Substrate |
|---|---|---|
| Face | Phenolic film | Eucalyptus face veneer (unsanded) |
| Core | Acacia or Eucalyptus | Full eucalyptus, edge-jointed or stitched |
| Glue | Phenolic WBP | WBP or BWP |
| Thickness | 12–21mm | 15–18mm most common |
| Application | Temporary, stripped after curing | Permanent structural installation |
Full eucalyptus-core plywood at 650–750 kg/m³ provides the dimensional stability required for subfloor applications — minimal shrinkage/expansion with seasonal moisture changes. Markets using this grade: Australia (AS/NZS 2269 structural), South Korea (flooring underlayment), and Middle East commercial construction.
“For structural subfloor applications, buyers consistently specify full eucalyptus core rather than acacia — the density difference translates directly to screw-holding strength and long-term dimensional stability under cyclic moisture loading.” — Lucy, International Sales Manager, HCPLY (6+ years export experience)

🔍 How to Specify Construction Plywood Correctly
Procurement errors for construction plywood from Vietnam almost always come from under-specifying the film and core. A purchase order that reads “18mm film-faced plywood, phenolic WBP” will receive very different panels from different factories unless four parameters are locked:
-
Film weight (gsm): Minimum 135gsm for standard formwork. Specify 160gsm+ for 15+ reuses.
-
Core species: Eucalyptus for heavy-load and structural. Acacia for standard construction.
-
Core construction: Stitched or edge-jointed (not loose-laid). Loose-laid cores delaminate under formwork pressure.
-
Edge treatment: Phenolic paint sealed edges. Unsealed edges are the #1 cause of panel failure during pour.

“The most common ordering mistake we see from first-time construction importers is specifying phenolic plywood without locking the film gsm and core species. We receive dozens of inquiries where buyers discover — after delivery — that they received local-film budget panels instead of export-grade. The specification sheet prevents this.” — Lucy, International Sales Manager, HCPLY
