Our offer

Grp :

Subor’s approach to a more sustainable business to undertake today’s projects with respect to future generations’ needs. Sustainable development must consider the effects it has on the economy, society, and environment as a whole. Subor, as a pipe manufacturer calculates the influence of its outputs on these elements at every step of its decision-making process for a sustainable business.

The superior properties of grp in terms of excellent hydraulic characteristics resulting in higher energy productivity and less pumping energy, high efficient production and transportation methods together with its long life cycle enable subor to offer the utmost quality with better sustainability to the future. As a result of having very low environmental impact compared to conventional pipe technologies due to its high level of material efficiency, subor grp products have low.

You shape it we make it

Subor non-circular (nc) grp pipes are primarily designed and developed for use in buried installations and commonly to reline existing non-circular pipelines.

The application areas of subor nc pipes are :

  • Sanitary sewer and old city sewer relining.
  • Storm water conveyance.
  • Chemically aggressive sewerwater.
  • The subor nc pipes offer the following advantages to the end-users :
  • Custom pipe lengths and profiles.
  • Long and effective service life.
  • Excellent impact resistance.
  • Increased chemical and abrasion resistance.
  • No need for additional lining or corrosion protection.
  • Superior hydraulic characteristics.
  • Lightweight, easy joining and fast installation.
  • Environmental friendly.

Production process

Subor nc grp pipes are manufactured in a filament winding technology controlled by a plc system that involves the winding of the glass fibers around a rotating structure called mold. The glass fibers wound around the internal and external resistance layers to ensure the nc pipe’s resistance

And rigidity, and the chopped glass fibers used on all layers to ensure axial resistance. The raw materials are bound by the thermoset polymerization reaction of the polyester. The filling material (silica sand) is used on the central layer to enhance the pipe rigidity in a cost effective way.

Fittings freedom to-choose

Subor nc grp pipes are also used to fabricate fittings such as elbows, tees, wyes and manholes, which can be designed on specific demand. Subor offers wide solution opportunities with over 200.000 different types of fitting design.


SUBOR’s approach to the quality concept is not limited to the production process and its product. The management mindset of SUBOR in all activities is an insight that considers the satisfaction of all stakeholders, especially the customers and adopts occupational health and safety as the fundamental policy.

Having established its management system upon such foundations, SUBOR has obtained certificates for ISO 9001 Quality Management, ISO 14001 Environmental Management, OHSAS 18001 Occupational Health and Safety Management and ISO 27001 Information Security Management System.
