FAQ

What plant managers and procurement heads ask us most.

We supply 9 refractory families: alumina firebricks (AR-30 to AR-80B), insulation bricks, Calderys castables & mortars, Morgan Thermal ceramic fibre, calcium silicate, acid-resistant bricks with bonding chemicals, metallic & ceramic anchors, pre-cast pre-fired blocks (PCPF), and on-site lining services.

Both. We manufacture PCPF blocks and select firebrick grades in-house at Bhandup, and we are the authorized channel partner for Calderys India Refractories (castables) and Morgan Thermal Ceramics (ceramic fibre).

Yes. Our manufacturing division routinely produces custom launder blocks, hearth blocks, burner blocks, and reheating furnace bottom blocks per client drawings.

For standard grades held in stock, yes — we serve both bulk procurement and small trial/replacement orders.

All figures shown are typical values within IS standards. For binding contract specification, we issue product data sheets with tested batch values — request a data sheet when placing your enquiry.

In most cases, yes. Share the competitor's spec sheet and we'll cross-reference the closest Arora grade or a Calderys/Morgan Thermal equivalent from our authorized range.

Yes. The AR-IS-8 Commercial grade and the AR-series firebricks are manufactured to IS 8 standards. Test certificates available on request.

WhatsApp us at +91 98200 25226 with product grade + quantity, or fill the enquiry form on this page. Standard turnaround: within 24 working hours.

Yes. We regularly service PSU steel, power, and cement plants under standard PO terms — including e-tendering and GEM portal transactions on request.

Standard terms are advance for first supply and 30–45 day credit thereafter, subject to credit review. Bulk / project orders are negotiated case-by-case.

Yes. We ship to all major industrial hubs across India via road transport, with bulk consignments arranged on FTL/PTL basis. Site delivery co-ordination is included.

Stocked grades: 3–7 working days. Custom PCPF blocks: 2–4 weeks depending on firing schedule. Emergency dispatches for shutdown situations can be arranged.

Yes. We maintain buffer inventory of critical grades and mobilize our contractor team on short notice for emergency relining work.

Yes — this is one of our strongest value-adds. Our founder brings 50+ years of refractory design experience. Share your application (industry, zone, temp, atmosphere) and we recommend the optimal grade + lining configuration.

Yes. Insulation upgrades using ceramic fibre and calcium silicate frequently deliver measurable fuel savings. We audit existing linings and quote payback-focused retrofits.

Yes. Our in-house team executes site installation, anchor welding, module assembly, controlled dry-out and commissioning under a single scope.

Client Voices

What plant managers, procurement heads & site engineers tell us.

★★★★★

"We've relied on Arora for our reheating furnace linings for the last 12 years. The AR-70B grade holds up shift after shift, and their site team completes changeovers on time — every time."

Rajiv MenonPlant Head · Steel Rolling Mill, Nagpur

"Calderys castables through Arora — same product, but with technical hand-holding on grade selection and zoning. Their engineering team knew exactly which Whytheat variant fit our ladle."

Deepak IyerRefractory Engineer · Foundry, Coimbatore

"When our boiler lining failed mid-season, Arora dispatched inventory within 48 hours and had crew on-site day three. Nobody else in the market could match that response."

Anita VermaProcurement Head · Power Plant, Gujarat
