1
The basics
What is GRC jali?
A perforated decorative screen made from glass fibre reinforced concrete. It is used on elevations, boundary walls, shafts and interiors for shade, ventilation and privacy.
What does GRC stand for?
Glass fibre Reinforced Concrete. GFRC (Glass Fibre Reinforced Concrete) means the same thing.
What is GRC jali made of?
Cement (grey or white), fine silica sand, water, a plasticiser, an acrylic polymer and alkali-resistant (AR) glass fibre.
Is GRC jali better than stone jali?
For most buildings, yes: it is much lighter, cheaper for custom patterns and quicker to install. Natural stone is chosen when the authentic material itself is the point, for example in heritage restoration.
What is the difference between GRC jali and FRP jali?
GRC is a concrete; FRP is a plastic. GRC is better outdoors and non-combustible; FRP is lighter and suits interiors. See GRC vs FRP.

Price and ordering
What is the price of GRC jali per sq ft?
Standard GRC jali starts at about ₹350 per sq ft supplied. Custom moulds, thicker panels, special finishes, freight and installation are extra and depend on your project.
What affects the price?
Pattern complexity, whether a new mould is needed, thickness, finish, total area, site location, fixing height, and whether you need installation.
Is there a minimum order?
1,000 sq ft in Delhi NCR and 1,500 sq ft for other cities.
How do I get a quote?
Send your elevation drawing or a photo with measurements, the design you like (catalogue number or image), and the site city. Contact us or WhatsApp +91 98130 29009.
Can I choose a design from a catalogue?
Yes. Download our jali design catalogue (PDF) and quote the design number. Catalogue designs are usually quicker because moulds exist.

Thickness, weight and strength
What is the standard thickness of GRC jali?
30–35 mm for exterior work. 25 mm for interiors; 40 mm or a steel frame for large or high panels.
What is the density of GRC?
About 1.8–2.1 t/m³ (1,800–2,100 kg/m³) depending on mix and method.
How strong is GRC jali?
Spray-up GRC typically has a flexural strength (MOR) of 20–30 MPa and premix 10–14 MPa, with compressive strength of 40–80 MPa. Full values are in our technical data sheet.
How much lighter is GRC than concrete?
Because it can be cast thin, a GRC element is typically up to 75% lighter than the same element in conventional precast concrete.
4
Installation
How is GRC jali installed?
Into RCC or masonry openings with stainless-steel anchors and grout, onto a steel sub-frame for large façades, or slotted between boundary pillars. See fixing methods.
Do you install, or only supply?
Both. Our own team installs across India, or we supply with fixing details for your contractor.
Can GRC jali be fixed on an existing building?
Yes, as long as the structure can take the fixings. We check slab edges and walls before designing the fixing.
How long does installation take?
It depends on area, height and access. Because panels are factory-made and light, fixing is much faster than building a screen on site.

Weather, finish and maintenance
Is GRC jali waterproof?
GRC is dense and handles rain well. A breathable sealer or exterior paint reduces water absorption and dirt pick-up.
Is GRC jali fireproof?
GRC is non-combustible; it does not burn or spread flame.
Can GRC jali be painted?
Yes, in any shade with exterior acrylic or texture paint. It can also be left in natural white or grey cement, or a sandstone tone.
How do I clean and maintain GRC jali?
Wash with water and a mild detergent using a soft brush. Avoid acid cleaners. Repaint painted jali when the colour fades, typically every few years in strong sun.
Can damaged GRC jali be repaired?
Small chips are repaired with matching polymer mortar. A badly damaged panel can be recast from the original mould and replaced.
Is GRC eco-friendly?
It uses far less material than solid concrete or stone for the same element, which reduces cement, transport and supporting structure.
