Bursa Steel Doors & Made-to-Measure Villa Door Manufacturing
Bursa holds two different climates inside one province: the Nilüfer–Osmangazi line down on the plain and the higher ground on the slopes of Uludağ ask different things of the same door. A large share of demand comes from the new villa developments on the plain.
Districts we serve: Nilüfer, Osmangazi, Yıldırım, Gemlik, Mudanya, Gürsu, Kestel, İnegöl, Orhangazi
Corrosion exposure
The plain and the city center sit in class C3 under ISO 9223. The Gemlik and Mudanya coastline approaches C4 under the influence of salt, while on the slopes of Uludağ the pollutant load is low and the class drops to the C2-C3 range.
What puts a door to the test in Bursa?
The hardest stretch for a door is the run of winter days that brings damp air and morning frost together. Water that melts during the day freezes again in the evening and collects around the threshold and the bottom profile; that cycle hardens the weather gasket, and in time the door begins to leak air along its bottom edge.
Delivery and installation
Delivery goes by road from Istanbul; survey appointments for Bursa are grouped onto set days of the week, which cuts the waiting time.
How we build for Bursa
In Bursa we never leave the threshold detail undecided: an automatic drop-down seal or a profile with a threshold is what actually makes the difference, however good the leaf is. For addresses on the higher ground along the Uludağ slopes we raise the thermal insulation value of the core fill.
Bursa Made-to-Measure Steel Door Manufacturing
Every leaf is built the same way regardless of the model: an Ereğli A1-grade 2 mm sheet frame, a 1.5 + 1.5 mm omega-folded monoblock leaf 90 mm thick, and 80 kg/m³ rock wool as the core fill. The lock and hinge areas are reinforced to 3 mm, and the lock itself is an Italian Mottura or Mul-T-Lock unit.
For flat entrance doors in the city center the priority is sound and heat insulation between the corridor and the flat. The 80 kg/m³ rock wool fill and the double gasket line do the work here; leaf thickness on its own does not.

An exterior door faces rain, sun and the day-to-night temperature swing head-on, so the cladding decision matters more than anything else. We use compact laminate, composite and marine plywood claddings that hold up outdoors, 304-grade stainless hardware as standard, and Şişecam 5+5 mm laminated glass in glazed models.
On the Gemlik and Mudanya coastline the class approaches C4, so stainless hardware becomes the default. On the higher ground along the Uludağ road the problem is not salt but freeze-thaw, and there the threshold detail — a drop seal or a threshold profile — is what decides whether the door survives the winter.

A pivot door carries its weight on floor and ceiling bearings instead of hinges, which is what makes sizes above 1.2 m and leaf weights past 200 kg possible. The bearing set is the critical component: we use a load-rated pivot system, and the floor bearing is positioned against the structural slab during installation, not into the screed.
Pivot doors go into the villa developments on the slopes and the newer projects on the plain. On sloping ground the floor bearing has to sit level even when the entrance platform does not, so we set the bearing plate during installation rather than assuming a flat floor.

Common questions from Bursa
Does Bayrakdoor carry out a free site survey in Bursa?
Yes. The site survey and measurement are free in Bursa and place you under no obligation. Our own team comes to the address, usually within 1-2 business days, measures the door opening and checks the installation conditions; you then receive a written, itemized quote.
How many days does delivery take for a steel door or villa door ordered in Bursa?
Production takes 20-25 days once the measurements are approved, and delivery from our Gaziosmanpaşa factory to Bursa is same-day, so installation follows immediately. Custom work moves that figure — the cladding, the lock system and any special dimensions all change it, so the exact date goes into your written quote.
What is the warranty on villa doors used outdoors, and how durable are the materials?
Manufacturing and workmanship defects are covered with no time limit, and a two-year official warranty certificate is issued on delivery. Component warranties follow their own manufacturers — up to 25 years on the lock system. Outdoors, durability comes down to the specification: an Ereğli A1-grade body, a cladding rated for exterior use such as compact laminate or composite, stainless hardware and a multi-layer paint system.
Is a standard villa door enough for a house on the Uludağ road?
The leaf can stay the same, but the core fill and gasket package should change. The higher the altitude, the wider the gap between inside and outside temperature; on a door left with standard insulation you will feel the cold on the inner face of the leaf in winter.
Is there a way to fix cold air blowing in under the door after the fact?
Yes. An automatic drop-down seal can be fitted to an existing leaf. But if the floor level under the opening is uneven, the lasting fix is a threshold profile.
How the process works in Bursa
Just send us the code of the model you like. Our team travels to Bursa, measures the width, height and wall thickness of the door opening, and checks the installation conditions on site. We then prepare a written, itemized quote. The site survey is free and doesn't commit you to anything.
Manufacturing happens at our own factory in Gaziosmanpaşa, Istanbul, and our own team handles installation. With no middlemen involved, one company is responsible for measurement, production and service.
Request your free survey for Bursa
Send the measurements of the door opening and a photograph over WhatsApp and we will price it the same day — the survey is free and places you under no obligation. If you would rather talk it through, give us a call; a model code is enough to start.
