Service area
Bolu Steel Doors & Made-to-Measure Villa Door Manufacturing
Bolu is forest, altitude and snow. Around Abant and Kartalkaya the villa and guesthouse stock keeps growing, and those entrances face conditions that few other provinces produce: deep snow, long frost and forest humidity that keeps every surface damp.
Districts we serve: Merkez, Gerede, Mudurnu, Mengen, Göynük, Seben, Yeniçağa, Dörtdivan
Corrosion exposure
The province sits in ISO 9223 class C3. There is no salt, but the forest humidity keeps the surface wet for far longer than the national average, and that wet time is what sets the corrosion rate.
What puts a door to the test in Bolu?
Snow lies deep and long, and the melt-freeze cycle around the threshold repeats through the season. Snow banked against an outward-opening leaf can block it entirely. Humidity means the surface rarely dries, so unsealed weld seams become places where water sits.
Delivery and installation
Shipments are planned in batches and the survey is combined with the installation. In winter the date depends on the road and snow conditions at the address, particularly for the higher villa and guesthouse sites.
How we build for Bolu
Sealed weld seams and a drained bottom edge come first, then the winter package: high insulation in the core fill, a cold-flexible double gasket line and an automatic drop seal. On exposed entrances we plan for the snow line, not just the door opening, and discuss the opening direction before production.
Bolu 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.
Forest humidity means the surface rarely dries, so every weld seam is sealed and the lower edge is drained. Without that, water finds the seam and stays there through the season.

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.
A mountain-house door gets the full winter package: high insulation in the core fill, a cold-flexible double gasket line and an automatic drop seal. We also discuss the opening direction before production, because snow banked against an outward-opening leaf can block it entirely.

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 entrances go into the villas and guesthouses around Abant and Kartalkaya. Snow load against the leaf is a real force here, so the bearing is chosen for the lateral load as well as the weight.

Common questions from Bolu
Does Bayrakdoor carry out a free site survey in Bolu?
Yes, and there are two ways to do it. The online survey is free and immediate: you send photographs and the measurements of the opening, and we return a written quote. For confirmed orders the on-site survey is also free — we combine it with the installation in a single trip to Bolu, so the distance costs you nothing.
How many days does delivery take for a steel door or villa door ordered in Bolu?
Production takes 20-25 days once the measurements are approved, plus road transport to Bolu. The figure moves with the specification: cladding, lock system and non-standard dimensions all affect it. Shipments are planned in batches and the installation date is fixed at the time of the order, so it appears in your written quote rather than being estimated afterwards.
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.
Which way should a mountain-house door open?
Inward, wherever the entrance is exposed. Snow banks against an outward-opening leaf and can block it completely; if outward opening is unavoidable we plan a canopy and a cleared apron in front of the door.
Does the forest humidity shorten the life of a door?
It does if the seams are not sealed. Without salt the corrosion is slow, but the surface here stays wet far longer than average, so water finds any unsealed seam and stays there. Sealed seams, a drained lower edge and stainless moving parts remove the risk.
How the process works in Bolu
Just send us the code of the model you like. Our team travels to Bolu, 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 Bolu
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.
