Iron Window Grill Design Photos and MS Grill Ideas

18 designs Window grills and windows Updated 8 Oct 2026

An iron window grill design in mild steel is still the first choice for most Indian homes, because nothing else gives so much strength for the money. Almost every grill wala in the country works in MS bars, strips and pipes, so getting one made is easy anywhere.

This page has 18 MS grill design photos in six groups: square bar, flat strip, pipe, wrought iron scroll work, simple lohe ki grill for village homes, and colour combinations. The details under each photo tell your fabricator the size, pattern and finish.

Iron needs paint to stay rust free. If you would rather skip painting, compare with our steel window grill design page. For plain, low cost patterns, the simple window grill design gallery also helps.

MS Window Grill Design with Square Bar

Solid square bar is the heaviest and safest option for ground floor windows. A 12 mm bar is the usual pick, 16 mm for shops and isolated houses.

Iron window grill design with twisted MS square bars painted black on a ground floor — Every second bar is twisted, which adds texture and makes the bar harder to bend. A tough choice for a ground floor room facing a lane.
*Material*MS 12 mm square bar
*Style*Plain and twisted bars
*Suits*Ground floor rooms
**Fabricator’s tip** Twist the bars cold on a jig before welding so all twists face the same way.

MS grill design with square bars forming a diamond grid in dark grey paint — Bars set at an angle form diamonds that look busier than a plain box grid. Popular on older homes and easy to match on new windows.
*Material*MS 12 mm square bar
*Style*Diamond grid
*Suits*Bedrooms, any floor
**Fabricator’s tip** Diamond joints trap paint drips, so spray paint the grill rather than using a brush.

Modern MS grill design with square bars in a stepped pattern on a white wall — Bars of three different lengths create a stepped skyline. A modern MS grill design that costs little more than plain bars.
*Material*MS 10 mm square bar
*Style*Stepped heights
*Suits*Modern homes
**Fabricator’s tip** Mark each step height on a drawing and get the owner to sign it before cutting.

Metal Grill Design with MS Flat Strip

Flat strip can be bent into curves and circles. It uses less steel than bar, so a metal grill design in strip is lighter on the wall and the pocket.

Metal grill design of MS flat strip circles painted maroon on a dining room window — Rings of flat strip welded inside a box frame give a soft, old style look. Maroon paint hides dust well on a busy road.
*Material*MS 25 x 5 mm flat
*Style*Rings in box frame
*Suits*Dining rooms
**Fabricator’s tip** Roll all rings on the same machine setting so the circles come out equal in size.

MS window grill design with zigzag flat strips in white on a kitchen window — Zigzag strips between straight rails look bright and clean in white. Fit it on a kitchen window that needs good airflow.
*Material*MS 20 x 3 mm flat
*Style*Zigzag
*Suits*Kitchens
**Fabricator’s tip** Use zinc primer under white paint in kitchens, as moisture lifts ordinary paint quickly.

Iron grill design with flat strip arches at the top painted bottle green — Small arches along the top rail match an arched window or a traditional facade. Bottle green looks right on old style homes.
*Material*MS 25 x 3 mm flat
*Style*Arched top band
*Suits*Traditional houses
**Fabricator’s tip** Grind the welds on each arch smooth, as rough joints show clearly under gloss green paint.

MS Pipe Grill Design for Windows

Square pipe and round pipe are hollow, so they look thick but weigh less. A pipe grill design suits large windows where solid bar would be too heavy.

MS square pipe grill design in a brown painted grid on a large hall window — Square pipe of 3/4 inch gives a bold frame look on a big window. Brown paint blends with wooden furniture inside.
*Material*MS 3/4 inch sq pipe
*Style*Large grid
*Suits*Big hall windows
**Fabricator’s tip** Seal every pipe end with a welded cap so rain does not rust it from the inside.

GI pipe grill design in silver paint on a terrace room window — Galvanised pipes resist rust better than plain MS and need less painting. Good for a terrace room that takes full sun and rain.
*Material*GI 1 inch round pipe
*Style*Vertical pipes
*Suits*Terrace rooms
**Fabricator’s tip** Touch up every weld on GI with zinc rich paint, because welding burns off the zinc layer.

Iron pipe grill with horizontal rectangular slats in bronze on a high window — Flat rectangular pipes placed like louvres give privacy and a modern feel. Use horizontal slats only on high sills that kids cannot climb.
*Material*MS 40 x 20 mm pipe
*Style*Horizontal slats
*Suits*High sill windows
**Fabricator’s tip** Weld the slats to vertical flat backers at both ends and the centre to stop any rattle.

Wrought Iron Scroll Grill Design

Scrolls, leaves and flowers bring the traditional look. Wrought iron style work is heavy and needs more labour, which is why it costs more than plain bar.

Wrought iron grill design with paired C scrolls in black on a front window — Pairs of C scrolls back to back form a classic pattern. It matches any front grill design iron work on the porch or balcony.
*Material*MS 12 x 6 mm flat
*Style*Paired C scrolls
*Suits*Front windows
**Fabricator’s tip** Join scrolls with forged collars rather than spot welds for the true wrought iron look.

Iron window grill with cast leaf vine pattern and antique gold highlights — A climbing vine with cast leaves looks rich when the leaf tips get a gold touch. Best kept for one feature window.
*Material*MS bar, cast leaves
*Style*Leaf vine
*Suits*Feature windows
**Fabricator’s tip** Hand paint the gold highlights only after the black topcoat dries fully for two days.

Close up of a wrought iron flower scroll grill showing smooth welded joints — This close view shows what good scroll work looks like: tight curls, smooth joints and even paint. Check these points before paying.
*Material*MS 10 mm sq bar
*Style*Flower scroll
*Suits*Traditional homes
**Fabricator’s tip** Ask for primer inside every curl before final paint, since rust starts where the brush cannot reach.

Simple Lohe Ki Grill Design for Village Homes

In village and small town houses, a lohe ki grill should be strong, cheap to make and easy to repaint. These simple iron grill design ideas keep steel and labour low.

Simple loha grill design with plain round rods on a blue village house wall — Plain round rods set into the wall during construction. It is the most basic window iron grill simple design and lasts decades.
*Material*MS 12 mm round rod
*Style*Plain vertical rods
*Suits*Village houses
**Fabricator’s tip** Set the rod ends at least 75 mm deep into the masonry with cement mortar.

Lohe ki grill with round rods and two cross strips painted red oxide — Two flat strips across the rods stop them from being spread apart. Red oxide alone protects for a while, but a top coat lasts longer.
*Material*MS rod and flat strip
*Style*Rods, two cross bands
*Suits*Small town homes
**Fabricator’s tip** Drill the flat strips and pass rods through them, which is stronger than welding on top.

Simple iron grill design in a box frame painted sky blue on a mud plaster wall — A welded box frame with bars can be fitted later with lugs, so it works for old houses too. Sky blue keeps it cheerful.
*Material*MS 10 mm square bar
*Style*Box frame with bars
*Suits*Old house retrofits
**Fabricator’s tip** Weld four lugs on the frame and grout them into chiselled holes in the old wall.

Iron Grill Colour Combination Ideas

The right iron grill colour can make an old grill look new. More shade ideas are on our grill colour design page.

Iron window grill design in black with gold painted tips as a colour combination — Black bars with small gold caps on top give a smart two tone finish. Works on a light wall where the dark grill stands out.
*Material*MS 12 mm square bar
*Style*Bars with ball caps
*Suits*Light coloured walls
**Fabricator’s tip** Mask the ball caps with tape while spraying black, then paint gold by hand.

MS grill design in grey with an orange outer frame on a white house — A grey grill with a bright outer frame gives a modern pop of colour. Repeat the frame colour on the main door for a matched look.
*Material*MS 25 x 25 mm tube
*Style*Grid with coloured frame
*Suits*Modern white houses
**Fabricator’s tip** Use PU paint for bright shades like orange, as enamel fades fast in strong sun.

White painted iron grill on a teal wall showing a fresh colour contrast — On a dark wall, a white grill looks crisp and makes the window seem bigger. White needs a wash before each festive season to stay fresh.
*Material*MS 20 x 5 mm flat
*Style*Box and diagonal
*Suits*Dark coloured walls
**Fabricator’s tip** White shows rust stains first, so use two coats of zinc primer before the enamel.

MS Sizes for an Iron Window Grill Design

Section	Typical size	Use
Square bar	10 to 16 mm	Ground floor security
Flat strip	20 x 3 to 40 x 6 mm	Curves, boxes, frames
Square or round pipe	3/4 to 1.5 inch	Large windows, light weight
GI pipe	3/4 to 1 inch	Rust prone areas

Price goes up with the weight of steel, number of joints and scroll labour. With small kids at home, hold bar gaps to 100 mm at most.

Painting and Care of Lohe Ki Grill

Clean off mill scale and rust with a wire brush before priming.
Apply red oxide or zinc chromate primer, then two coats of enamel or PU paint.
Repaint every 2 to 3 years, or yearly near the sea.
Dust the pattern with a soft paint brush every month.

Grill design questions

Which is the best simple iron grill design for a ground floor?

Plain 12 mm MS square bars at 90 to 100 mm gaps, with two cross strips, give the best strength for the cost. Twisting some bars adds a little style.

What is the difference between MS grill and iron grill?

In daily talk they mean the same thing. Almost all lohe ki grill work today is done in MS, mild steel. True cast or wrought iron is rare and used only for decorative parts.

Is a pipe grill design as strong as a square bar grill?

Solid bar is stronger for the same size. Pipe looks thicker but is hollow. For upper floors pipe is fine. For ground floors use thick wall pipe or solid bar.

What is the best iron grill colour combination?

Black with gold, grey with a bright frame and white on a dark wall all work well. Pick a grill colour that contrasts with the wall so the pattern shows.
