Three Diamond UPVC manufactures complete UPVC window profile systems in Chennai — casement and sliding frames, sashes, mullions, tracks and glazing beads — engineered with 2.5 mm walls, lead-free compound and titanium-dioxide UV stability. Supplied wholesale to window fabricators, builders and dealers across Tamil Nadu.
A window is only as good as the profile it is cut from. Our window systems are extruded with uniform wall thickness and tight chamber tolerances, which fabricators feel immediately at the workbench: cleaner 45° cuts, stronger corner welds, gaskets that seat without fighting, and reinforcement that slides in without persuasion. Every full-system order ships with matched auxiliary sections and hardware, so your production line never stalls waiting for a missing bead.
The workhorse for apartments, villas and offices: outer frames, Z-sashes, T-mullions and glazing beads with 2.5 mm walls and a 3-chamber design. Double EPDM gasket seating gives airtight, rain-tight closure and up to 40 dB noise reduction in the finished window. Full specifications on the 60 Series casement page.
Track and shutter sections engineered for smooth, low-friction operation with walls up to 3.5 mm and a 5-chamber layout — built for balcony fronts, wide living-room openings and commercial façades. Details on the sliding system page.
For high-rise, coastal and industrial sites where wind load and salt air punish ordinary sections, the 80 Series industrial system brings a 112 mm, 6-chamber profile with 2.5 mm walls.
