Subor GRP pipes are used in fittings such as standard elbows, T, reduction, flange, etc. as well as special spools that can be designed on request.

For fitting production, pipes are first cut at the desired angles and forms. The cut pipes are attached by connecting glass fiber mat (CSM), glass fiber webbing-lattice (WR), and glass fiber multiaxial materials to each other by polyester recin.

This practice is called "Lamination Method". Subor obtained a patent in 2009 and started applying the new method that allows obtaining high resistance at connection points using multiaxial (resistant in three axes) materials that was developed with extensive long-term tests by the Subor Technology Center.

Multiaxial fiber materials are cut at the desired dimensions in automated, computer-controlled cutting machines. Thus, possible cutting and workmanship faults are prevented and losses are reduced. Upon the completion of lamination process, fittings are taken into the post-cure furnace and the reaction is completed. With this practice, the resistance of the winding layers increase and the new method makes it possible to produce fittings at higher pressure classes.
