Keto Ply manufactures IS 1659 block board at Yamunanagar on kiln and air seasoned pinewood and hardwood battens, and supplies it across Patan to university library shelving, hostel almirahs and Siddhpur and Radhanpur furniture workshops, in 12 mm to 25 mm boards.
IS 1659 | Batten Core | 12 mm to 25 mm
Block board exists for one reason: span. A seven foot wardrobe shutter or an eight foot table top cut from plywood will bow in time, because a veneer core has nothing running the length of the board to carry that load. A block board does, and its solid timber battens work like a row of small joists. Patan's biggest block board buyers are institutional, and the two things they order most are the two things a batten core does best: long library and storage shelving, and almirah and door shutters for hostel blocks. Both are ordered in single large lots and both are expected to last without maintenance. Keto Ply rips pinewood and hardwood timber for its block boards and seasons it by kiln and air before pressing, and IS 1659 sets the rest: battens no wider than 30 mm, laid edge to edge without significant gaps, seasoned to not more than 12 percent moisture.
Pinewood and hardwood timber is ripped and then seasoned by kiln and air, so the battens are stable before they ever go into a board.
Battens no wider than 30 mm laid edge to edge as IS 1659 requires, so there are no hollow pockets to telegraph through a laminated face.
Direct dispatch to Patan, Siddhpur, Chanasma, Harij and Radhanpur workshops and sites, scheduled against the site programme.
Every Keto Ply panel carries the brand's borer, fungus and anti-termite guarantee in writing.
What a batten core does on a Patan institutional contract, and where plywood still wins.
Request a Sample BoardThe battens run the length of the board like a row of small joists, which is what keeps a seven foot wardrobe shutter or a long table top from bowing. A veneer core has nothing running that way and will sag over the same span.
IS 1659 caps batten width at 30 mm and requires them laid edge to edge without significant gaps. That is what stops a shutter showing hollow lines through laminate a year after it is fitted, and it is the first thing to check on a cheap board.
Keto Ply rips pinewood and hardwood and seasons it by kiln and air before pressing. IS 1659 requires core battens at not more than 12 percent moisture, because timber that goes in wet shrinks later and opens gaps inside a finished board.
A block board weighs noticeably less than plywood of the same thickness, which matters on full height wardrobe shutters and flush doors where the hinges carry that weight every day for years.
Library and storage shelving, almirah and door shutters, long tables and partitions. Stay with plywood for small carcass boxes and drawer units.
Supplied from the Yamunanagar unit with dealer, workshop and project pricing for Patan, plus dealership openings across Mehsana and North Gujarat.
