CPWD & MES Compliant Diamond GRG Ceiling Tiles for Government Projects
Approved Nationwide
for Public Infrastructure Use
Diamond’s GRG (Glass Reinforced Gypsum) Ceiling Tiles are officially approved in both the CPWD Delhi Schedule of Rates (DSR) and the Military Engineering Services (MES) Schedule of Rates (SOR). This dual approval ensures that our semi-perforated and fully-perforated GRG tiles can be directly specified in tenders for central, state, and defence sector projects across India—without deviation or special approval.
Why GRG Tiles Are Preferred
in Government Projects
GRG ceiling tiles are renowned for their lightweight strength, acoustic performance, fire resistance, and clean finish. Diamond manufactures these tiles in-house using high-grade materials and maintains strict quality control to meet public sector standards.
Our GRG range is especially suited for:
- Auditoriums and conference halls
- Government office buildings
- Educational and institutional facilities
- Defence infrastructure and cantonments
- Public-sector residential and healthcare spaces
Project Benefits
- No substitution approvals required
- Faster tender inclusion and project onboarding
- Confidence in regulatory and inspection compliance
- Proven performance across major public-sector builds
