KS Concrete Panel Standard

Basic Specifications

Grade

AA Grade

Premium AA-grade panel with high-quality veneers throughout all layers. Minimal defects, uniform composition, and superior structural integrity for high-performance formwork and demanding construction applications.

Color

Full-piece veneer B Grade

Single-piece Grade B natural wood veneer appearance with minor color variation and small repairs. Provides a largely uniform natural timber look for commercial applications.

Application

Formwork

Concrete forming and shuttering panels engineered to withstand repeated pours, chemical exposure, and high moisture on construction sites. Formwork plywood features overlay surfaces (phenolic, HDO, or MDO) for smooth concrete finishes and extended reuse life.

Back

Natural wood color

Uncoated natural hardwood back veneer displaying original wood grain and color. For applications where the back surface is visible or where a natural timber finish is preferred without additional film or coating.

Back Color

Natural wood color

Untreated natural hardwood back color showing the original grain pattern. Indicates no additional film, paint, or overlay coating is applied to the back surface.

Core Grade

AA Grade

Core veneers all graded AA with minimal defects, tight joints, and uniform density. Delivers superior internal bonding strength and consistent panel performance under structural load.

Face

Full-piece veneer A Grade

Single-piece Grade A hardwood face veneer with no joints, splices, or finger-jointing. Provides a seamless, premium appearance for high-end furniture, architectural paneling, and decorative plywood where visual continuity is essential.

Face Color

Full-piece veneer B Grade

Single-piece Grade B face veneer showing natural wood character with minor color variation and small, well-executed repairs. Maintains a largely uniform appearance for commercial applications.

Glue

WBP Melamine Top

Premium Water Boil Proof melamine adhesive with top-tier formulation. Delivers superior bonding strength and moisture resistance approaching phenolic glue performance, with cleaner glue lines for quality-conscious applications.

Moisture Content (%)

12

Wood Species

Acacia, Eucalyptus

Acacia mangium — fast-growing tropical plantation hardwood with density of 580–600 kg/m³. Offers good structural strength, natural durability, and excellent cost-effectiveness. Widely used for plywood cores across Southeast Asian manufacturing.; Eucalyptus plantation hardwood with high density (650–750 kg/m³), tight grain, and superior structural rigidity. Excellent dimensional stability and moisture resistance — the closest tropical species to Baltic Birch in performance characteristics.

Applicable Certifications

EN13986 CE Marking, FSC COC Certification, ISO9001 Certification, KS Mark

European harmonised standard EN 13986 for wood-based panels in construction. CE Marking certifies compliance with EU requirements for structural performance, formaldehyde emissions, and fire reaction under the Construction Products Regulation (CPR).; Forest Stewardship Council Chain of Custody certification. Verifies the wood originates from responsibly managed forests and is tracked through every stage of the supply chain from forest to final product, supporting sustainable forestry practices.; International quality management system standard. Certifies that manufacturing processes follow documented procedures for consistent product quality, continuous improvement, and customer satisfaction across all production batches.; Korean Standards (KS) certification for plywood and wood-based panels. Certifies compliance with KS F-series quality and performance standards required for construction products sold in the South Korean market.
