For Builders, Contractors & Fleet Owners

How an On-Site Fuel Tank Pays for Itself.

Every machine that stops for fuel is a machine not earning. An owned tank turns refuelling from a daily errand into a bulk purchase.

Zero Downtime Refuelling

Fuel is where the machines are. Operators start the shift full instead of queueing behind a bowser or driving to a station.

Machine hours back every week

Buy Diesel in Bulk

Bulk deliveries are priced below retail pump price. Fill 4,000 litres at a time and the difference goes straight to your margin.

Typically 5 to 12% below pump price

Stop Theft and Spills

Lockable cabinets, metered pumps and a double-wall shell. You know how much went in, how much came out and nothing reaches the ground.

Every litre accounted for

Compliance Built In

Double-wall containment, overfill protection and leak-tested seams built to UL 142 practice, so environmental audits are a formality, not a fear.

Audit-ready documentation

One Tank, Every Site

Transportable cubes move full on a flatbed. When the job finishes, the tank goes to the next one. No pumping out, no leaving fuel behind.

Asset that follows the work

Direct From the Factory

You buy from the plant that welds the tank, not a chain of distributors. Fleet orders in container loads, priced from Mundra Port.

Manufacturing

Laser-Cut. CNC-Bent. Welded. Tested Before It Ships.

Seven controlled operations from sheet to shipped tank, run by engineers who commissioned press, weld and paint shops for automotive OEMs. Every tank gets a leak test. No exceptions.

01

Laser cutting

3 kW fibre laser on a 2 × 6 m bed cuts shells, baffles and cabinets straight from your DXF.

02

CNC bending

3 m and 6 m press brakes hold the same angle on the first tank and the thousandth.

03

MIG welding

Twenty stations at 250 A and 500 A, with jigs for every model so the inner and outer walls stay true.

04

100% leak test

Every inner tank and every interstitial space is pressure-tested and signed off before paint.

Test certificate shipped with each tank
05

Shot blasting

Blasted to a clean, anchored profile so the coating bonds for the life of the tank.

06

Paint and cure

Two booths and a drying oven. Your RAL colour, dry-film thickness checked, gloss and warranty to your paint standard.

07

Fit-out, decals, packing

Pump brackets, gauges, decals and kits fitted. Loaded and secured for the container, 54 km from the port.

Our Plant

A Fuel-Tank Plant 54 km From the Ship.

Most tank makers sit hundreds of kilometres inland and pay for every pothole in dents, scratches and freight. Our dedicated facility at Bhuj, Kutch is an hour from Mundra Port and six kilometres from an airport with daily flights from Delhi and Mumbai.

Phase 1 · Live now: prototypes and pilot builds

Sample tanks are built at our Rudrapur facility near Delhi, with laser, bending, weld, blast and paint capacity already in place.

Phase 2 · January 2027: mass production at the port

Plant and weld shop commissioning, then blast and paint, then ramp from 2 to 6 container loads a month.

Quality & Compliance

Built to UL 142 Practice, Run on Deming Discipline.

UL 142 is the standard for steel above-ground flammable-liquid tanks in North America. Our founder holds the UL Solutions Manufacturer Technical Representative qualification, the credential a plant needs to build to it. The rest is the quality system we brought from the automotive line.

  • UL 142 qualified MTR · awarded July 2024, valid five years.
  • Double-wall construction with interstitial monitoring point on every cube.
  • 100% leak test on inner tank and outer shell, certificate per serial number.
  • Paint to your standard · RAL shade, dry-film thickness, gloss and warranty agreed before the first sample.
  • Galvanised hardware with specified coating thickness for brackets and fittings.
  • Deming (JUSE) process discipline · QCDMS gap analysis and PDCA on every programme.

Logistics

Priced from the port, not the factory gate

Being 54 km from Mundra takes hundreds of road kilometres, and the damage that comes with them, out of every load. That saving shows up in your landed price and in tanks that arrive as they left.

Fewer road kilometres · fewer dents · lower freight

FAQ

Questions Fleet Owners Ask First.

What do you need from us to quote a fuel tank?
A drawing, a DXF or simply a reference model and capacity, the quantity per year, your destination port, and your paint and decal spec if you have one. If you only have a photo and a size, send that. We will come back with a spec sheet and price within five working days.
Are the tanks double-walled and UL 142 compliant?
All cube and stationary tanks are double-wall steel with an interstitial space, built to UL 142 construction practice under a UL-qualified Manufacturer Technical Representative. Listing and marking for a specific model and market (UL, DOT, ADR or AS 1940) is scoped per programme so the paperwork matches where the tank will actually be used.
Do you ship to the USA, Australia and Europe?
Yes. Tanks ship containerised from Mundra Port, Gujarat, on FCA or Ex-works terms, to the USA, Canada, Australia, the UK, Ireland and mainland Europe. Your freight forwarder is welcome, or we can arrange the forwarder and share the shipping schedule.
What are the lead times and minimum quantities?
A proto sample takes roughly eight to ten weeks from spec lock. Production ships in container loads, starting at two loads a month and ramping to six as your forecast grows. For a single-site fleet order, a mixed load of sizes is fine; the container is the practical minimum.
Can you build to our brand and colour?
That is most of what we do. RAL colour, decals, pump brackets, kits and packaging to your spec. Your name goes on the tank; ours does not.
What are the commercial terms?
Proto samples are paid in advance with the purchase order. Production runs are 60% advance and 40% against the bill of lading, on FCA or Ex-works Incoterms, moving to open terms as the programme matures. An NDA is signed before any drawings change hands.
Where are the tanks made?
Prototypes and pilot batches at our facility in Rudrapur, Uttarakhand, near Delhi. Mass production from January 2027 at the dedicated fuel-tank plant in Bhuj, Kutch, Gujarat, 54 km from Mundra Port. You are welcome to visit either site; Bhuj has daily flights from Delhi and Mumbai.
