Sultanbeyli Steel Doors: Survey, Manufacture, Installation
Sultanbeyli holds a population above 378,000 across 29 square kilometres and 15 neighbourhoods. Most of the building stock went up within a short stretch of time from the 1980s onward, so a large share of the apartment buildings share a similar floor count and a similar entrance layout. Frame openings tend to come out close to one another from block to block, which makes planning several flats in one building noticeably easier than it would be in a district with a mixed construction history.

What fails on a steel door, and why
A door usually gets changed because something has failed: the leaf catches on the frame, the bolt misses its keep, noise from the landing carries inside. All three trace back to the installation or to the material. The rows below put the symptom beside what we do about the same item, with the values from the technical table.
What turns up on site
The frame was not built for the opening. Nothing shows in the first months. As the building settles, the leaf starts to catch on the frame and the bolt struggles to find its keep. Most winter calls that begin with "the door will not close" come down to this.
How we handle it
We measure at the address and the frame is built to that opening. Every model in the catalogue is made to measure, so we are not bedding a ready frame into the gap with foam.
What turns up on site
The door skin is thin. Knock on the leaf and it rings hollow, and after a while the area under the handle and the line of the lock flexes inward. The finish then lifts along that flex.
How we handle it
The skin is the same across all four series: 2 mm Ereğli A1 steel door skin. The thickness does not drop on the entry model; the difference stays in the finish and the design.
What turns up on site
The core is sparse, or there is none. Conversation on the landing carries into the home and the hall stays cold in winter. A hollow note instead of a solid one when the door shuts points at the core.
How we handle it
The leaf is filled with 150 kg/m³ rock wool core. The same core does the work for sound and for heat.
What turns up on site
The lock holds at one point only. With the leaf fixed at the lock line alone, force pulls the door away from the frame, and the leaf flexes even where the bolt itself holds.
How we handle it
The lock ties the leaf to the frame at several points: Kale 256G 14-point lock. It is one of the four values that do not change between series.
Sultanbeyli Steel Door prices
A steel door in Sultanbeyli starts from $480. The figures do not part on the body: all four series carry 2 mm Ereğli A1 steel, 150 kg/m³ rock wool and Kale 256G lock. The difference sits in the finish, the measurement and the hardware. A net figure follows the on-site survey, in a written quote.
| Series | Which choice | What sets the band | Price band |
|---|---|---|---|
| Eko | A first home, a rented apartment | A standard door opening measurement and a deliberately narrow finish palette keep this band at the lower end. | from $480 |
| Plus | A home entrance, visual variety | At the same standard measurement, a wider set of finish, colour and handle options lifts the band. | from $700 |
| Pro | An apartment building communal entrance, a workplace | The mechanism chosen for heavy opening and closing traffic, together with communal area hardware, sets this band. | from $1,160 |
| Ultra | Made-to-measure size, one-off design | Manufacture to a made-to-measure size, with a wide finish and accessory combination, sets the top of the band. | from $1,740 |
The figures here are starting ranges; they move with the measurement, the surface finish and the hardware you choose. For a net price on your own door, message us on WhatsApp or ask for a free on-site survey.
Every model carries 2 mm Ereğli A1 steel door skin, 150 kg/m³ rock wool, a Kale 256G 14-point lock and TSE EN 1627 certification as standard.
Every model carries the standard warranty; on upper-tier models it runs longer, depending on the material chosen.
The on-site survey and the installation are free within Istanbul. For an address outside Istanbul, please call our customer line.
The items that set the price
Four items move the price: the door frame measurement, the series chosen, the surface finish and hardware, and the work that turns up on site. If the door opening is not a standard one, the frame is made to measure. Taking out an old frame is discussed during the survey, not added afterwards.
Door frame measurement
If the door opening is not a standard one, the frame is made to measure; material and labour follow from that.
Series and model
All four series share the same body, the same insulation and the same lock; the difference sits in the surface finish, the design and the warranty period.
Surface finish and hardware
The type of finish, the colour, the handle and any extra accessory are what move the quote most.
Work that comes up on site
If the old frame has to come out or the measurement needs correcting, it is discussed during the survey and listed as a separate item in the quote.
Sultanbeyli Steel Door services
Sales and replacement work for Sultanbeyli sit on separate pages. Beside the model and price pages there are headings for apartment entrance doors, garden entrances, hingeless pivot doors and communal area fire doors. Each page sets out its own measurement, manufacture and installation sequence, so you can go straight to the one you need.
Every model, price and replacement page. If you are not sure which one to open, the selection guide below narrows it down.
What separates the series
The four series run through the same measurement, manufacture and installation sequence. Eko is for a first home or a rented apartment, Plus for home entrances that want a wider surface finish and colour choice, Pro for apartment building communal entrances and workplaces, Ultra for made-to-measure sizes and one-off design. The table sets that difference out row by row.

Why Sultanbeyli moves fast once the measurement starts
Because the buildings date from a similar period, the survey stage is quick; the attention goes elsewhere instead.
- Apartment buildings from a similar period
- Frame openings come out close to one another, so we can measure several flats in one building on a single visit and often plan manufacture together.
- Narrow stairwell landings
- Blocks from this period can have a tight stairwell landing. We measure the turn the leaf has to make alongside the frame opening itself.
- Shop entrances along the main road
- Ground-floor units along the main road are used far more heavily than a flat entrance, and we recommend hardware for them accordingly.
The survey is free, and the measurement and the model decision happen on the same visit.

Written warranty
Every model carries a warranty as standard. On upper-tier models an extended warranty applies, depending on the material chosen.
We re-measure on site before fitting
We do not simply take the measurement you send. Before fitting, our team comes to the address and measures the door opening again; the risk of a wrong measurement sits with us, not with you.
The net price comes in a written quote
We do not quote a net price over the phone. After the survey, what will be done and what it costs is set out item by item in a written quote.
Photographs from the job
These were taken on site once the door was fitted, not in a studio: the floor is unfinished, the protective film is still on the threshold and nothing has been tidied. You can see how the frame meets the wall and where the architrave ends. No place name goes under them, because the address was never recorded.
How to measure the door opening
A tape measure is all the door opening needs. Width from one inner face of the frame across to the other, height from the top of the threshold to the inner face of the frame head, then the wall thickness. Send those three figures and we can say over the phone which model fits your opening.
Four measurements, in order
Measure inside the door frame at three heights
Open the leaf fully, rest the tape against one inner face of the frame and read it off at the opposite inner face. Repeat near the top, at the middle and close to the floor; if the three differ, write down the smallest, because the leaf has to pass through that gap. The height runs from the top of the threshold to the inner face of the frame head.
Keep the architrave edge separate
The architrave is the frame that covers the joint between the door frame and the wall. Measure it from one outer edge to the other. That figure comes out larger than the one inside the frame: in the catalogue, models with an inside measurement of 90 x 200 cm have an architrave edge between 104 x 208 cm and 108 x 210 cm, and the difference is the width of the architrave itself.
Write down the wall thickness
On the side face of the opening, measure from the inner wall surface to the outer wall surface, and leave the architraves out of that figure. The depth of the frame is built to it, so we need it as much as the width and the height.
Tell us how the floor will finish
If parquet or ceramic tile is going in under the threshold, the measurement has to allow for the finished floor. A covering laid afterwards leaves the door catching along the bottom. Where the floor is not ready, we work out the clearance during the survey.
What to send us
- Width and height inside the door frame, in centimetres.
- Wall thickness, in centimetres.
- Which way the door opens: hinges on the right or on the left.
- A photograph of the opening if you have one, with the corner of the frame in shot.
Do not round the figures. Write the half centimetre too, because the frame is built to it.
All 163 models in the catalogue are made to measure. Of the 122 models with a listed measurement, 119 carry the same inside figure, so 90 x 200 cm is a common opening; outside it the model stays and the frame changes.
With the figures to hand, answer the first question in the selection guide
Sultanbeyli Steel Door selection guide
If you are unsure where to begin, start from the question: an apartment door, an apartment entrance door, or a house with a garden? If the door still stands but the lock, hinge or door frame is giving trouble, the replacement pages are right. For a new door, read the models first and prices after.
These four questions come up on the phone more than any others, before the on-site survey is even booked.
- Does my door need replacing, or is a repair enough?
- If the leaf and the door frame are sound, the trouble usually sits in the lock, the cylinder, a hinge or the strike plate, and those are changed on site. Once the frame has pulled away from the wall, or the leaf has bowed, a repair only buys time. We settle which it is at your address.
- Is an apartment door the same thing as an apartment entrance door?
- No. An apartment entrance door opens and shuts hundreds of times a day and works alongside a door closer and entry automation. On an apartment door what matters most is sound and heat insulation, together with the lock. The two are separate products and sit in separate price bands.
- Can I take the measurement myself and send it to you?
- It helps us picture the job, but it cannot stand in for the manufacturing measurement. The frame opening shifts with the plaster on the wall, the threshold level and the direction the door swings, and a wrong figure only shows itself on installation day. The on-site survey is ours to do.
- How do I know which series to choose?
- Where the door will stand decides the series. The table below maps the situations we meet most often to the page that covers each one.
Tick the three rows
We write out which price band and which models the three rows you tick come to, right below. Nothing is sent and the address of the page does not change.
Tick all three rows and the answer appears here.
The inner frame measurement on 119 of the models in the catalogue is 90 x 200 cm. If your opening is close to that, we carry on with the ready measurement.
The door frame is made to your own opening. Every model in the catalogue is made to measure, and we take the measurement at the on-site survey.

Neighbourhoods
We cover the whole of Sultanbeyli district and do not split it by neighbourhood. The list below names every neighbourhood in Sultanbeyli; we travel to all of them on the same terms. At the measurement appointment the team comes to your address and measures the door opening there; the model decision is made during that same visit.
Sultanbeyli Steel Doors: frequently asked
Which neighbourhoods of Sultanbeyli do you cover?
All 15, including Mehmet Akif, Battalgazi, Orhangazi and every other part of the district. The survey, manufacture and installation run the same way everywhere; what changes is the hardware recommendation for a shop entrance versus a flat.
Is there a published figure for how old the buildings in Sultanbeyli are?
No. We hold no verified district-wide figure for building age or stock, though in practice a large share of it dates from a similar construction period, which the survey confirms address by address rather than from a statistic.
I own a flat in Sultanbeyli but live outside Turkey. Can the whole process run in English?
Yes. Send photographs of the existing door on WhatsApp and we arrange the survey through a relative, tenant or managing agent holding the keys. The written quote and the measurement are sent to you in English, and manufacture waits for your confirmation.
Can several flats in the same building book one appointment?
Yes. Because frame openings tend to be similar across these buildings, we often measure more than one flat in a single visit and can plan the manufacture together, though each door is still quoted on its own hardware and finish.
Is the on-site survey free in Sultanbeyli?
Yes. The survey and the installation are free anywhere inside Istanbul, and that applies the same way across all 15 neighbourhoods.
Do the ground-floor shops along the main road need a different kind of door from a flat?
Yes. A shop entrance on the main road opens far more often through the day than a household door, so the lock and hinge count recommended there is higher than for a residential entrance.
