Powder coat is the skin. Antique gold or copper is makeup. People order the makeup and then blame the skin when the sea or the dust does what it always does.
We hear this after one wet season on a Kochi elevation, or after a dusty summer on a Jaipur farmhouse. The lantern looks dull and the buyer says the finish failed. Sometimes they are right about the wipe. They are almost never right about the body, as long as the body is cast aluminium. Rust is iron, and paint on an iron body doesn't change the metal once that paint opens. Coastal air eats a thin antique wipe faster than it does in a dry Noida society, and desert grit sands a shine. Neither is the metal rotting. Finish and body are two different things, and if you confuse them at order time you will argue with the monsoon later.
Dealers ask for "the gold one that stays shiny". Architects ask for a finish code that sounds like plating. Homeowners send a Pinterest screenshot taken indoors. None of those is a climate brief. The brief is whether the fitting sits under open sky or a covered porch, whether the wind brings salt or highway dust, and how often someone will wipe it. Answer those and the catalogue colour makes sense.
What we put on the metal
The sequence on our catalogue pieces is simple. Die-cast aluminium first, then powder coat, then the antique gold, antique copper, matte black or raw grey you picked. The antique is a wipe on the raised casting, which is why it photographs well and why a season of salt fog or grit makes it look older. The metal underneath is the same piece.
Powder coat is the real outdoor layer. It is baked on, and it chips if you hit it with a ladder or an electrician's pliers. Under a chip you still have aluminium, not a hole filling with orange. On iron, a chip is the start of a stain down the pillar.
The wipe doesn't fill pits. It sits on the high points of the casting, the flowers, rings and edges. Flat panels look more even, while busy castings look richer in a photo and age more unevenly outdoors. That is how light and dirt catch a raised surface, not a defect. If you want a flat, even face for twenty years, you are shopping for a different object than an antique gate lantern.
Matte black hides dust on a Gurugram villa and antique photographs well for a farmhouse reel. Neither replaces aluminium. If you want the gold to stay showroom bright on a sea-facing wall, you are asking a wipe to outrun the weather. I would rather tell you that before you pay, and suggest black for that wall and antique for a sheltered porch.
Humidity, door joints and the green stain inside the glass
We get calls with a photo of milky or greenish glass and a sentence that starts "your powder coat failed". Usually the powder coat is fine and the lantern has become a bowl.
Humidity doesn't need a cyclone. North Indian nights get wet enough. Air cools, moisture sits on cold metal, then the sun cooks it, and if water can enter at a joint, it will. The usual entry points are the cap where the lantern meets the pillar, the hinge of the door, the lip where the door meets the body, a gasket that was never seated, and a hole drilled in the top for a wire with no drip loop. Water follows the wire in and stays.
When the door doesn't shut flush, every dew and every shower adds a little more. Dust mixes with that water, and inside the glass you get a film that is grey, greenish or sometimes brown. People call it rust. On aluminium it almost never is. It is dirt and mineral water sitting in a lantern that was never closed properly. Open it, clean the glass, dry it, and shut the door until it latches. Then look at the finish again.
Check the hinge before you blame the factory. Move the door and see whether it seats on the whole lip or only one corner, and whether the latch has been bent in transit or by an electrician forcing it. A door that looks shut from the driveway and still lets rain in is an open bowl. We cast aluminium so the body survives. We don't cast a magic seal that forgives a door left ajar for three monsoons.
Glass or acrylic as specified on the quote keeps the bulb side cleaner only if the door works, and "with glass" is not the same as "marine sealed". An empty housing means you or your electrician finish the weather path. Either way, the joints decide whether you get a green stain. Use a soft cloth on the outside of the antique and on the inside of the glass when you service the holder. Don't pressure wash into the hinge, and don't use an acid cleaner, which eats the wipe and then gets blamed on the powder coat. If the stain came with a cracked glass off the truck, that is transit, so send a photo within forty-eight hours. If it came after a year of open sky and a door that never latched, that is the site.
Coastal air and desert dust
Salt air doesn't need a flood. It sits on the wipe overnight. In Kochi and the other coastal stretches we already send to, the antique dulls first on the high spots of the casting. Wipe it with a soft cloth. Don't take sandpaper to it because a photograph looked brighter last year, because you will take the wipe off and then complain the metal looks raw. That was always the aluminium.
Desert and highway dust in Jaipur, Ahmedabad and open farmhouses sand the shine. Matte finishes forgive that better than a bright antique. The body doesn't care, but the photograph does. If your site is both dusty and wet by season, expect the makeup to age and the casting to stay, and expect the joints to matter more than the colour name on the invoice.
We already supply dealers and projects in Delhi, Gurugram, Faridabad, Noida, Lucknow, Pune, Bengaluru, Hyderabad, Guwahati and Kochi, and the city name doesn't invent a new metal. It changes how fast the wipe looks tired and how hard humidity works the door. If you are still tempted by iron because it was cheaper on a counter, read what a monsoon does to a gate light.
How to choose a finish for the actual site
On an open pillar with full sky and salt wind, lean towards matte black or a darker antique rather than a bright gold you expect to match the day it left Aligarh. On a covered porch, or a farmhouse gate away from spray, antique earns its keep. Where there is highway dust and nobody cleaning, matte wins. Next to white walls that show every rust streak, don't put iron and call it outdoor lighting.
A pair of antique gate lights should match each other more than they match a phone photo. Daylight on the pillar lies less than a screen does, so if you can, check two finishes side by side outdoors, not under a shop tube light. We pack what you ordered, but we can't pack the light of the evening you imagined.
Empty housing versus glass and LED is a quote line, not a finish. Coastal buyers sometimes assume "with glass" means sealed for salt, but glass only keeps the bulb dry if the door shuts and the install is honest, and it doesn't make the antique wipe marine. B22 is standard, with E27, E26 and B15 on request, and the bulb isn't included unless the quote says so.
What kills a finish that was fine when it left
Wire brushing to "brighten" antique, acid cleaners meant for floors, a pressure wash aimed at the casting, holes drilled in the cap with no drip loop, a door left ajar for months, and a lantern mounted so it rubs the gate every time the gate opens. None of that is the powder coat failing in the oven. That is the site wearing the piece down.
Transit can scuff a high point, so send a photo within forty-eight hours if the carton looks wrong. A scuff we can discuss. A season of salt with no photo until you want a free remake is a different conversation. Use a soft cloth, mild soap, rinse and dry, and skip any polish that claims to restore gold plating we never said we sold.
What the twelve-month cover includes
Manufacturing defects are covered for twelve months from delivery, and we send the part that failed, not a cash refund. A wipe that dulled in salt air is not a manufacturing defect. A glass cracked in transit needs a photo within forty-eight hours. A lantern left with the door open so the bowl filled with rain is an installation problem. Full terms are on returns.
Custom finishes and custom lantern sizes are a different conversation. Stock catalogue finishes follow the sequence above, while custom sizes need a physical sample and 50 or more pieces, and custom is final. Don't order a gold wipe for a sea wall and then ask us to remake it in black for free because the photograph aged. Trade lots start at 10 pieces and one to five pieces are at retail list. A short catalogue lot often leaves within a few working days and a larger lot takes longer. Terms, payment and freight are on About, shipping and returns.
If the finish looks tired after a season, send a photo before you strip it. Often the metal is fine and you are looking at dirt in the antique. A holder we can replace. A body that rusted isn't ours, because we cast aluminium.
What we will not print
We have not completed an international order yet, though we are set up to ship. We show AED on the site as a converter and we bill in INR. For coastal India we already dispatch. I won't invent an IP rating so a tender looks German, and I won't write "marine grade antique" on a wipe, because that sentence sells once and comes back as a fight.
Architects who need a one-pager should write powder coat plus antique wipe on the drawing, not "PVD gold" or a made-up plating thickness. I have set that out on the spec sheet post. And if someone in the market offers you "same finish, half price", ask what the body is when you lift it, and whether the bill comes from the works that cast it.
