Overview
Furnace manufacturers in Faridabad and Ballabgarh, forging and heat-treatment shops in Ghaziabad and Sahibabad, aluminium and steel units in Bhiwadi, and incinerator and boiler operators across NCR consume fire bricks, insulating bricks, castable and mortar on every build and relining. Wedge Industries Limited supplies these as an order-linked pack with the calcium silicate, microporous and ceramic fibre it already sells, so the OEM or plant gets the whole lining from one supplier.
Dense fireclay and high-alumina bricks form the hot face; insulating fire bricks, calcium silicate and microporous the back-up; castables and mortars the joints, burner blocks and repairs. Standard grades ship from Indian makers; special grades are imported through the Wedge group.

Installation and specification notes
Bricks are laid with the matched mortar at the joint width the design specifies; castables are mixed and vibrated or gunned by the refractory contractor; insulating bricks, microporous and calcium silicate go behind the hot face. Wedge supplies materials and can refer supervised relining contractors; castable shelf life is checked before dispatch.

Frequently asked questions
Which brick grade for an industrial furnace hot face?
Fireclay or 45–60 % alumina bricks are usual for heat-treatment and boiler furnaces; higher alumina for melting. Send the operating temperature and the existing brick reference and Wedge confirms the grade.
Do you supply castable with the bricks?
Yes. Castables and mortars matched to the brick grade are supplied with every brick and calcium silicate order.
What is an insulating fire brick?
A lightweight, porous brick used behind the dense hot-face brick to cut heat loss and shell temperature; it sits alongside calcium silicate, microporous and ceramic fibre in the lining.
Do you deliver to Faridabad furnace makers?
Yes. Order-linked supply is delivered across NCR from Faridabad; bulk orders ship direct from the maker to the plant.
Can Wedge supply the whole furnace lining?
Yes — hot-face bricks, castables, insulating bricks, microporous, calcium silicate back-up and ceramic fibre from one supplier, with technical data for each layer.
