Keto Ply manufactures IS 303 MR grade moisture resistant plywood at Yamunanagar and supplies it across Surat to Vesu and Pal flat interiors, Ring Road market fittings and Adajan and Katargam kitchens, in 6 mm to 19 mm boards.
IS 303 | MR Grade | 6 mm to 19 mm
Surat sits on the Tapi a few kilometres from the sea, and its interiors live in humidity most of the year, with salt air reaching everything from Dumas Road to Hazira. The city also builds faster than almost anywhere in Gujarat, so a large share of its wardrobes and kitchens are only a season or two old and will meet their first real monsoon soon. Moisture resistant plywood is bonded for that repeated wetting and drying. Keto Ply supplies MR grade across the Keto Elite, Keto Supreme and Keto Signature ranges, all pressed from full panel hardwood veneers and treated against termite, borer and fungal attack. Where the panel will meet standing water rather than damp air, we supply Keto Marine BWP grade to IS 710 instead, and we will say so before you order.
Water resistance, mycological and moisture content checks are run on production batches against IS 303 before the consignment is dispatched.
Full panel veneers with no gaps or overlaps, so there is no void inside the board for moisture to collect and work the glue line apart.
Direct dispatch to Ring Road, Vesu, Adajan, Katargam and Hazira workshops and sites, scheduled against the site programme.
Every Keto Ply panel carries the brand's borer, fungus and anti-termite guarantee in writing.
Six things Surat architects, carpenters and shop fitters check before they trust a board to a humid location.
Request a Sample BoardIS 303 puts MR grade through two cycles of three hours in 60 degree water and eight hours of drying before the glue line is tested. That is the condition a wardrobe back on a Mumbai external wall actually lives in, not a single soak.
No patch joints, overlaps or hollow pockets, so there is no void inside the board where moisture can sit and work its way along the glue line.
Kiln plus air seasoning brings moisture content into the 5 to 15 percent band IS 303 requires, and calibrated sanding holds thickness, so shutters do not swell out of line after fitting.
Tapi humidity and coastal salt air are what turn untreated plywood into food. The treatment cycle carries the Keto Ply anti-termite and anti-fungus guarantee, which matters more in Surat than inland.
MR grade is built for damp air, not standing water. For sink bases, bathroom vanities and anywhere the panel gets genuinely wet, we supply Keto Marine BWP grade to IS 710 and tell you so before the order goes out.
Supplied from the Yamunanagar unit with dealer, workshop and project pricing for Surat, plus dealership openings across the Udhna and Sachin belt.
Acceptance values laid down in IS 303 (Plywood for General Purposes - Specification), tested as per IS 1734.

|---|---|---|---|
| Water Resistance (MR) | IS 1734 (Part 5) | Two cycles of 3 hours in 60°C water and 8 hours drying at 65°C | The bond survives repeated wetting and drying, not just one soak. |
| Mycological Test | IS 1734 (Part 7) | Pass for adhesion of plies | The glue line resists fungal attack in a humid interior. |
| 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. |
| Bending Strength (MR) | IS 1734 | MOR 30 N/mm² along and 15 across; MOE 4000 and 2000 N/mm² | Shelves and shutters carry load without sagging over time. |
| Step Up: BWP Marine | IS 710 | Boiling water proof bonding, unextended phenol formaldehyde | For sink bases, vanities and standing water, specify Keto Marine instead. |
