Every kilogram of UPVC profile we manufacture is sold B2B. These are the buyers who build their businesses and projects on Three Diamond supply — and what each of them gets from us.
Profiles are your raw material — we treat your orders that way: tiered repeat-purchase rates, same-day loading on stock, complete-system deliveries (profiles + steel + gaskets + hardware) and technical data for every section. Fabricator partner program →
Project-long rate locks, phased dispatch matched to slab cycles, and lead-free certified material your consultants can sign off. From gated communities to commercial towers across Tamil Nadu. Bulk order terms →
Specification support: section drawings, technical data, acoustic and thermal performance, colour and laminate options, and cut samples for material boards. Technical downloads →
Protected territories, manufacturer-direct margins, freight-supported replenishment from Chennai and marketing collateral. Territories open across Tamil Nadu. Distribution network →
Lead-free compound, CIPET lab test documentation and GST invoicing for tender compliance — schools, hospitals, housing boards and public buildings. Quality assurance →
Offices, hotels, hospitals, showrooms and factory buildings — including our 80 Series for wide, wind-exposed openings and coastal sites. All applications →
We do not sell retail and we do not compete with our buyers for end customers. Homeowners who contact us are referred to fabricator partners in their city — your customers stay yours. That is the foundation the dealer network and fabricator program are built on.
We'll match series, quantities and commercial terms to your business.
