ISI 303 MR Grade Plywood: Premium Commercial Wood Panels from Perumbavoor

​

            While Marine Grade is essential for wet areas, ISI 303 MR Grade Plywood is the backbone of premium interior woodworks across Kerala. At Kerala Plywood, we manufacture high-performance Moisture Resistant (MR) panels specifically engineered to withstand the humidity of the South Indian climate while providing superior structural stability for home and office furniture.

​

What is ISI 303 MR Grade Plywood?

​

         MR Grade (Moisture Resistant) Plywood, certified under IS:303, is an interior-grade wood panel designed for areas with high humidity but no direct water contact. It is the best choice for bedroom wardrobes, wall paneling, ceiling work, and office partitions in Kochi and Ernakulam due to its high warp resistance and superior screw-holding strength.

​

Why Choose Kerala Plywood’s MR Grade?

​

                  In a market crowded with commercial boards, our manufacturing process in the Perumbavoor plywood hub ensures a product that outlasts standard alternatives.

​

Zero-Gap Core Composition

​

                 We utilize automated core composers to eliminate "core gaps" and overlaps. This ensures that when your carpenter cuts the board for a wardrobe in Kochi, the edges remain solid and structurally sound without hollow spots.

Superior Moisture Resistance

                  While not "waterproof" like our ISI 710 Marine Ply, our ISI 303 panels are "Moisture Resistant." They are treated to resist the dampness of the Kerala monsoon, preventing the swelling and delamination commonly seen in low-quality commercial ply.

Eco-Friendly & Safe

                   Our MR Grade plywood adheres to E1 emission standards, ensuring that the indoor air quality of your home or office in Ernakulam remains safe and free from heavy chemical odors.

Ideal Applications for IS:303 Plywood

​​​

• Premium Wardrobes: High screw-holding capacity for heavy-duty hinges.

• Wall Paneling: Lightweight yet rigid for decorative vertical surfaces.

• False Ceilings: Ideal for structural frameworks in residential projects.

• Office Workstations: Durable surfaces that handle daily wear and tear.

Frequently Asked Questions

 

Is ISI 303 Plywood waterproof?

No, ISI 303 is Moisture Resistant (MR), not Boiling Water Proof (BWP). For areas like kitchens or bathrooms in Kerala, we recommend our ISI 710 Marine Grade. For all other interior furniture, ISI 303 is the most cost-effective and durable solution.

​

Why buy MR Grade plywood directly from a Perumbavoor manufacturer?

Sourcing directly from Kerala Plywood in Perumbavoor ensures you receive factory-fresh timber and genuine ISI-certified quality. By eliminating middlemen, we provide the most competitive 18mm plywood prices in Kerala for bulk orders and large-scale interior projects.

 

How do I verify a genuine ISI 303 stamp?

A genuine sheet will have the ISI:303 mark along with the manufacturer’s unique CM/L license number. You can verify our certification on the official BIS website to ensure you are getting authentic Kerala Plywood quality.
