UHPC: When Performance Demands More
UHPC (Ultra-High Performance Concrete) is a cutting-edge cementitious composite engineered for architectural elements where extreme compressive strength (150 - 220+ MPa), ultra-slender cross-sections, and complex self-supporting geometry are essential.
Where GRC is the core of our lightweight architectural facade offering, UHPC extends the realm of possibility for ultra-thin fins, monumental organic shells, and self-spanning architectural sculptures.

Ultra-thin sections under 15mm with unmatched rigidity and zero structural deflection.
02 Extreme Strength
Compressive strength exceeding 200 MPa, 4x higher than conventional high-grade concrete.
03 Complex Geometry
Self-supporting canopies, aerodynamic fins, and double-curved parametric envelopes.
04 Refined Finish
Ultra-dense molecular packing yielding an impervious porcelain-smooth stone luster.
GRC + UHPC
Two Material Capabilities. One Architectural Approach.

Frequently Asked Questions About GRC & UHPC
Everything architects, builders, and specifiers need to know about Glassfibre Reinforced Concrete (GRC) and Ultra-High Performance Concrete (UHPC).
What is GRC and how is it made? +
GRC (Glassfibre Reinforced Concrete), also known as GFRC, is concrete reinforced with alkali-resistant glass fibres, making it significantly lighter and stronger than traditional RCC. RIYON uses the Direct Spray-Up method with 100% Japanese Nippon AR glass fiber (>16.7% Zirconia) and high-purity White Portland Cement. Our 7-step manufacturing process includes: Architect Concept → CAD/3D Parametric Design → 5-Axis CNC Mould → White Matrix Preparation → Direct Spray-Up → Precision Curing & Demoulding → Dry-Fix Site Installation.
What is the difference between GRC and UHPC? +
GRC has a flexural MOR strength of 18–30 MPa, weighs 25–30 kg/m², and is 75% lighter than RCC — ideal for facade panels, jali screens, and lightweight cladding. UHPC (Ultra-High Performance Concrete) achieves compressive strength of 150–220+ MPa and supports ultra-slender sections under 15mm — ideal for self-supporting canopies, aerodynamic fins, and structural facade blades. RIYON manufactures both GRC and UHPC at our Gujarat facility.
What GRC products does RIYON manufacture? +
RIYON manufactures a comprehensive range: Curved Facade Panels & Cladding, Parametric Jali Screens & Sun Shades, Corinthian Columns & Capitals, Dentil Cornices & Mouldings, Balusters & Balustrades, 3D Fluted Wall Panels, Landscape Planters & Water Features, Entrance Portals & Arches, and UHPC Slender Fins & Canopies. All products are cast in high-purity White Portland Cement with ISO 9001:2018 certified quality control.
Where is RIYON located and which areas do you serve? +
RIYON GRC & UHPC manufacturing works are located at Kamalpur, Palanpur, Banaskantha District, Gujarat, India (PIN 385410). Backed by Taj Precast Industries since 2008, we deliver projects across India — Gujarat, Rajasthan, Maharashtra, Delhi NCR, Karnataka, Telangana, Tamil Nadu, Kerala, UP — and internationally to Bangladesh, Indonesia, UAE, Saudi Arabia, Qatar, Oman, Kuwait, and the USA.

What is the flexural MOR strength of RIYON GRC panels? +
RIYON Direct Spray-Up GRC panels achieve a flexural Modulus of Rupture (MOR) of 18–30 MPa, which is 3–5× higher than traditional RCC (3–6 MPa) and 2–3× higher than generic premix GFRC (8–10 MPa). This is achieved through 100% Japanese Nippon AR glass fiber with >16.7% Zirconia and Dow Acrylic Polymer technology. All panels are tested per BS EN 1170 standards.
How much lighter is GRC compared to traditional concrete? +
RIYON GRC is approximately 75% lighter than traditional RCC. GRC density is 1,600–1,900 kg/m³ vs RCC's 2,300–2,400 kg/m³. A typical 12–15mm panel weighs only 25–30 kg/m², dramatically reducing structural loading, foundation costs, and installation time — ideal for high-rise cladding, retrofit projects, and complex curved geometries.
What is the lifespan of GRC facades? +
RIYON GRC facades are engineered for a service life exceeding 50 years with minimal maintenance. White Portland Cement, Nippon AR glass fiber (>16.7% Zirconia), and Dow Acrylic Polymer ensure zero efflorescence, superior weathering resistance, and monsoonal-proof durability. GRC's hydrophobic surface makes it ideal for India's diverse climate zones.
