Structured purchasing preparation and supplier follow-up in Türkiye.

What International Project Buyers Source from Gaziantep GAOSB

Many European and North American hospitality buyers know İstanbul and Bursa for custom furniture, yet the majority of Türkiye’s commercial hotel corridor/ballroom carpets, carpet tiles, acoustic underlays and nonwoven geotextiles are manufactured in Gaziantep (GAOSB)—exporting to over 170 countries.

Alongside contract flooring, Gaziantep’s petrochemical-polymer processing scale makes it a price-leading manufacturing base for XPS extruded polystyrene boards, APP/SBS modified bitumen waterproofing membranes, synthetic PVC/TPO geomembranes, PPR-CT hot-water plumbing pipes and polyurethane construction foams/sealants.

Preventing Polymer Filler & Hospitality Fire-Certificate Mistakes

  • Fire Certificate Authenticity (Cfl-s1 / ASTM E648): Residential polypropylene rugs must never be shipped for hotel corridors requiring EN 13501-1 Cfl-s1 / Bfl-s1 polyamide/wool contract specs (SS-DESK €190 + SS-PRE €490).
  • Calcium-Carbonate (CaCO3) Over-Filling Trap in Membranes & Pipes: Ultra-cheap PPR/PVC pipes or bitumen membranes often contain excessive mineral filler that cracks in winter—verify virgin resin declarations, nominal kg/roll weights and EN lab reports.
  • 1h30m Direct Flight (SAW → GZT): Our team flies directly from İstanbul Sabiha Gökçen to Gaziantep Airport (25 min from GAOSB) for single-day plant audits and pre-shipment inspections.
