Keto Ply manufactures IS 710 marine plywood at Yamunanagar and supplies it across Mumbai to kitchen and bathroom joinery, sea facing flats and commercial wet areas from Colaba to Borivali, in 6 mm to 25 mm boards.
IS 710 | Marine Grade | 6 mm to 25 mm
Marine plywood is the most loosely used word in the Indian plywood trade. A board is marine grade because it meets IS 710, which means an unextended phenol formaldehyde bond, 72 hours submerged in boiling water with the plies still intact, and pressure preservative treatment against termite and borer. It is not marine grade because the word appears on a sticker. Mumbai has the deepest plywood dealer market in the country and the widest gap between what a board is called and what it is. Most buyers here never see the sheet: the contractor buys it, the carpenter cuts it, and the flat owner finds out what grade went under the sink three monsoons later. Keto Marine Plywood is manufactured to IS 710 on selected premium hardwood veneers with a high density core, bonded with unextended phenol formaldehyde resin, and the lot test report goes out with the consignment.
Boiling water resistance, glue shear and mycological checks are run against IS 710, and the lot test report is issued with the consignment rather than on request.
Unextended phenol formaldehyde resin with no fillers or extenders, and board marking that carries the manufacturer, year and batch as the standard requires.
Consignments to island city, western, central and harbour suburb workshops and sites, slotted around Mumbai's daytime truck restrictions.
Every Keto Ply panel carries the brand's borer, fungus and anti-termite guarantee in writing.
What actually separates marine plywood from a board that is only sold as marine, and how a Mumbai buyer can tell the difference before paying for it.
Request a Sample BoardThree things together, all set by IS 710: an unextended phenol formaldehyde bond, 72 hours submerged in boiling water with the plies still intact, and pressure preservative treatment. A board that misses any one of them is not marine grade, whatever it is called on the invoice.
IS 710 requires the manufacturer name or trademark, the year of manufacture, the timber species and a batch number marked on the face near one corner. Ask for the lot test report against that batch number. In Mumbai, where the contractor usually buys on your behalf, asking for that report is the only practical way to know what went into the sink base.
Preservative is pressure impregnated to the retention IS 710 requires, so termite, borer and fungal protection goes through the board rather than sitting on the surface where a saw cut removes it.
IS 710 sets a wet bending strength requirement, not just a dry one, so a shelf in a sink base or a vanity still carries what it is asked to carry after it has been soaked.
Sink bases, bathroom vanities, utility joinery and sea facing flats from Colaba to Borivali where salt air never leaves. Marine grade across an entire dry flat is money spent for nothing, and we will say so before you order.
Supplied from the Yamunanagar unit with dealer, workshop and project pricing for Mumbai, plus dealership openings across the western and harbour suburbs.
Acceptance values laid down in IS 710 (Marine Plywood - Specification), tested as per IS 1734.
| Test | Method | Requirement | What it means on site |
|---|---|---|---|
| Water Resistance | IS 1734 (Parts 4 & 5) | Submerged in boiling water for 72 hours | Three full days of boiling, against eight hour cycles for BWR grade. |
| Glue Shear Strength (wet) | IS 1734 (Part 4) | 1000 N average, 800 N minimum | The glue line still carries load while the board is soaking wet. |
| Mycological Test | IS 1734 (Part 7) | No appreciable separation at the veneer edges | The bond resists fungal attack in permanently damp locations. |
| Preservative Retention | IS 10013 | Pressure impregnated, minimum 12 kg/m³ for CCA, CCB or ACC | Protection goes through the board, so a saw cut does not expose untreated wood. |
| Wet Bending Strength | IS 1734 (Part 11) | MOR 25 N/mm² along and 15 N/mm² across, tested wet | A shelf in a sink base still carries load after it has been soaked. |
| Moisture Content | IS 1734 (Part 1) | Not less than 5% and not more than 15% | A seasoned board that will not swell and push shutters out of line. |
These are the published IS 710 acceptance criteria for marine plywood. The lot specific test report is issued with every project consignment.
