A 20 x 80 mm ten-slot section used for trolley and workstation frames. The section choice sets the load, the weight and the cost.

01Extrusion profiles for Delhi NCR manufacturing

The Delhi NCR belt, Noida, Greater Noida, Gurugram, Manesar, Faridabad and Ghaziabad, is India’s automotive components and white goods corridor. The buyers there order aluminium extrusion for things that move inside a plant: trolleys, workstations, kanban racks, line-side carts, conveyor and robot guarding, and appliance test frames.

That use pattern sets the questions. It is not “which alloy”, it is “will the fifth delivery look like the first” and “how much does the frame weigh against what it carries”. This page answers both, then the clearance side for an import.

How do you control colour between anodising batches?

By measuring, not by eye. Clear anodising is the safest: there is no dye to drift, only film thickness, which is controlled. For dyed work we hold the batch to a Delta E figure against a retained master sample, and we keep the charge record so a later batch can be run to the same parameters.

Why does the section weight matter so much on a trolley?

Because the operator pushes it. A frame that is 20 per cent heavier is 20 per cent harder to start and stop, all day. On a trolley or a line-side cart the right question is not *how strong* but strength per kilogram, and that is a section choice, not an alloy choice.

A 20 x 80 section. Ten slots across an 80 mm face give many fixing positions without adding material where it is not needed.

0230 series versus 40 series for NCR plant furniture

The two series cover almost every trolley, workstation and guard in a Delhi plant. The wrong choice is usually visible within a month as a sagging shelf or an over-built frame.

Item	30 series	40 series	Note
Typical section	30 x 30, 30 x 60, 30 x 90 mm	40 x 40, 40 x 80, 40 x 120 mm	both take 8.2 mm slot on the common sizes
Slot	8.2 mm	8.2 mm	M6 and M8 bolts
Weight per metre	about 0.8 to 2.0 kg/m	about 1.3 to 3.4 kg/m	40 series is roughly 1.6x the mass
Load for a 1 m shelf span	up to about 40 kg	up to about 100 kg	indicative, four supports
Best for	shelves, light frames, enclosures, ducts	trolleys under load, machine guards, heavy benches
Cost per metre	lower	higher	the difference is material, not process

Line-side trolley, light parts: 30 x 30 mm frame, 20 mm shelf pitch. Weight matters more than strength.
Workstation with a monitor and tools: 30 x 60 mm legs, 30 x 30 mm rails.
Trolley carrying castings: 40 x 40 mm or 40 x 80 mm, and check the shelf deflection, not just the yield.
Machine guard and robot fence: 40 x 40 mm, because the guard also has to take an accidental impact.
Enclosure and control cabinet frame: 20 series, because it is carrying panels, not load.

Deflection, not strength, usually decides it. A shelf that is strong enough but springs 10 mm under load feels wrong to an operator. Design to a deflection limit, and let the section follow.

03Batch colour: what to specify

Anodising is a batch process and the shade depends on the alloy, the film thickness, the electrolyte and the dye, all of which drift a little. Buyers who specify “black” and nothing else will eventually receive two blacks.

Finish	Colour risk	What to put in the order	Batch strategy
Clear anodised	low, thickness only	10 to 15 micron, clear	any batch will match closely
Black anodised	medium, dye load and thickness	15 micron, black, master sample	one run per assembly where visible
Bronze or champagne	higher, dye sensitive	master sample, plus Delta E limit	one run per project
Powder coated RAL	low, RAL is defined	RAL number and gloss level	one powder batch per project

The practical rule for a Delhi buyer with a visible assembly: order the whole assembly from one anodising run. If the assembly runs to several thousand metres, then a retained master sample plus a Delta E figure is the next best control.

04Inland transport and clearance to Delhi NCR

Delhi NCR is inland, so the container arrives at a west coast port and comes north either by rail to an Inland Container Depot or by road.

Route	Entry	Inland leg	Suits
West coast by rail	Mundra, Pipavav, Nhava Sheva	rail to ICD Tughlakabad	container loads into south Delhi
West coast by rail, north	Mundra, Pipavav	rail to ICD Dadri	Noida, Greater Noida, Ghaziabad
Sea to Kolkata, then rail	Kolkata	rail west to Delhi	rarely economic, longer transit
Air	Delhi IGI	direct	a few kilos, urgent sample only

ICD Tughlakabad is the main inland depot for south Delhi and Faridabad.
ICD Dadri serves the Noida and Greater Noida belt and is often quicker for those plants.
6 m lengths travel by rail and road without difficulty on this corridor; the constraint is the trailer length, not the depot.
GST and IGST are creditable for a registered business, so the tax is a timing cost on a Delhi import.

05Small batch, many variants: the changeover question

Delhi NCR buyers often run several product variants on one line, which means many short cutting and drilling runs rather than one long one. That changes the quoting structure, and it is worth understanding before comparing two suppliers.

Order pattern	Dominant cost	How it is quoted	Best route
One section, one cut, large quantity	metal and conversion	per metre	new die if volume is high
One section, many lengths	cutting and sorting	per piece, plus setup	cut to size from stock
Many sections, small quantity each	setup per section	per piece, setup split	stock lengths, cut locally
Many sections, drilled	machining setup	per piece, fixture included	cut and drill to drawing

The honest advice for a mixed line: buy stock lengths and cut them in your own plant if you have a saw, and buy only the complex drilled parts as finished pieces. The cutting is where the quick-change cost sits.

06Import from China versus a local supplier

Import from China

A non-standard section or a finish not made locally
A large quantity where the unit price matters
A consistent anodising batch across the whole order
A container can be made up from several sections
The schedule allows a 4 to 6 week total lead time

Buy from a local supplier

You need a few lengths this week
The section is a standard Indian size
The quantity is small and freight dominates
You want a local relationship for repeat small orders
The line cannot wait for a sea shipment

Most NCR buyers run both. The local supplier covers the urgent and the small; the import covers the bulk and the section sizes the local extruders do not carry.

07Failure modes on a Delhi NCR line

What goes wrong	Why it happens	Design it out by
Two deliveries do not match in colour	separate anodising runs on one visible assembly	one run per assembly, or a master sample plus Delta E
Trolley shelf sags in service	section chosen on strength, not on deflection	design to a deflection limit and step up the section
Frame too heavy to push all day	40 series used where 30 series would take the load	check strength per kilogram, not strength alone
Bolt loosens on a moving trolley	vibration on a bolted joint with no locking	use a serrated washer or a thread-locking compound
Clearance delay at the ICD	documentation gap, or the depot chosen is the wrong side of the city	match the depot to the plant and prepare the papers before arrival
Anodised frame will not earth	the anodised film insulates the joint	mask a bonding pad or use a star washer through the film

08What to check before you order for Delhi

Procurement checklist for a Delhi NCR order

Confirm the series and section: for example 30 x 60 mm.
Confirm the alloy and temper.
Confirm the finish, and for dyed work the master sample and Delta E.
Confirm the cut list and the cut tolerance.
Confirm the deflection limit if the part is a shelf or a trolley deck.
Confirm the ICD: Tughlakabad or Dadri.
Confirm the trade term and who clears customs.
Confirm the documents: mill certificate, dimensional report, film report.

09Questions Delhi NCR buyers ask

Do you supply aluminium extrusion to Delhi NCR?

Yes, in 6063-T5 and 6061-T6, cleared through ICD Tughlakabad or ICD Dadri, or delivered to a Noida, Gurugram or Faridabad plant.

How do you control colour between batches?

Clear anodising by film thickness; dyed work to a master sample and a Delta E figure, from a recorded charge.

Should I use 30 series or 40 series?

30 series for shelves, light frames and enclosures; 40 series for trolleys under load, machine guards and heavy benches.

What bolt fits the slot?

The common 8.2 mm slot takes M6 and M8 with a matching T-nut.

Can you cut and drill to a variant list?

Yes. Send the cut list and the hole pattern; the setup is shared across the variants.

What is the lead time to Delhi?

About four to six weeks including the inland leg and clearance.

What we need to quote a Delhi NCR order

The section list and the alloy.
The finish, and the master sample and Delta E for dyed work.
