Kastamonu Steel Doors & Made-to-Measure Villa Door Manufacturing
Kastamonu covers forest highlands and a Black Sea coastline, and the two need different doors. Inland the winter and the snow govern; on the İnebolu and Cide shore the humidity and salt do. The province also has a substantial stock of historic timber houses, where the entrance has to satisfy conservation rules.
Districts we serve: Merkez, Taşköprü, Tosya, İnebolu, Cide, Araç, Devrekani, Daday, Bozkurt, Azdavay
Corrosion exposure
Inland the province sits in ISO 9223 class C2-C3, dry and cold. The İnebolu and Cide coastal strip moves toward C3-C4 under Black Sea influence, where the surface stays wet for long periods.
What puts a door to the test in Kastamonu?
Inland the frost period is long and snow lies for weeks, putting the threshold through repeated freeze-thaw and stiffening standard gaskets. On the coast the problem reverses: the surface rarely dries and water finds any unsealed seam. Forest humidity affects both.
Delivery and installation
Deliveries are planned in batches and the survey is combined with the installation in a single programme. In winter the installation date follows the snow and the road conditions, particularly for the highland districts.
How we build for Kastamonu
Inland we specify a thermally broken leaf, high insulation in the core fill, a cold-flexible gasket and an automatic drop seal. On the coast the priority moves to sealed seams, a drained bottom edge and stainless moving parts. For historic timber houses we build a steel core with a timber-look cladding that meets the conservation requirements.
Kastamonu 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.
Inland the winter governs and the gasket is the first part to fail, so we use a cold-rated profile with a thermally broken leaf. On the coast the same door would be specified differently — there the seams and the drainage matter more.

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.
For historic timber houses we build a steel core with a timber-look cladding that meets the conservation requirements, agreed before production. Elsewhere the exterior door gets the winter package inland and the wet-coast package at İnebolu and Cide.

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 newer detached houses in the centre and the highland districts. Snow accumulates against the leaf, so the bearing is specified for the additional lateral load and the drop seal is planned around the snow line.

Common questions from Kastamonu
Does Bayrakdoor carry out a free site survey in Kastamonu?
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 Kastamonu, so the distance costs you nothing.
How many days does delivery take for a steel door or villa door ordered in Kastamonu?
Production takes 20-25 days once the measurements are approved, plus road transport to Kastamonu. 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.
Can a steel door be used in a historic timber house?
Yes, with a timber-look cladding and proportions that meet the conservation requirements. The core is steel, so the security is unchanged, while the street elevation stays consistent with the building. The design is agreed before production.
Does a coastal door in İnebolu need different hardware from one in the centre?
It does. On the coast the surface stays wet and salt is present, so the moving parts are stainless and the seams are sealed. Inland the same door would be over-specified — there the winter package matters more than the corrosion package.
How the process works in Kastamonu
Just send us the code of the model you like. Our team travels to Kastamonu, 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 Kastamonu
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.
