Specifiers and government buyers don't need adjectives — they need documents and measurements. This page lists exactly what goes into a Three Diamond profile and how we prove it.
Three Diamond profiles are extruded from lead-free UPVC compound with calcium-zinc stabilisers — the formulation that replaced lead-based stabilisers in quality-conscious markets and is increasingly mandatory in institutional specifications. Loaded with titanium dioxide (TiO2), the material resists UV degradation, so profiles don't yellow, chalk or embrittle under years of Tamil Nadu sun and coastal salt air.
Our profiles have been tested at CIPET — the Central Institute of Petrochemicals Engineering & Technology, the Government of India's premier plastics testing institution. The report is public: view or download it here, attach it to your tender file, or request a copy with your quotation. If your consultant needs additional parameters tested, talk to us — we'd rather test than argue.
Fabricators: fewer weld failures and rejected cuts, consistent gasket seating. Builders: material that passes consultant scrutiny without drama. Government contractors: lead-free certification and CIPET documentation ready for the tender file. Dealers: a quality story you can sell confidently — backed by paper, not promises. More on why buyers switch to us.
We'll send the CIPET report, spec sheets and samples with your quotation.
