Keder is an edge reinforcement profile used to connect coated fabric, textile panels or printed graphics to rails, frames or structural systems. It usually consists of a solid or flexible core wrapped with coated fabric, creating a strong fabric edge that can slide into a track or lock into a frame.
Keder is widely used in tents, marquees, awnings, canopies, banners, soft signage, marine canvas, tarpaulins and industrial fabric applications. It helps fabric panels install more securely, align more consistently and perform better under tension.
What Is Keder Made Of?
Keder is commonly made with a core material and an outer coated fabric. For PVC keder, the core is usually made from virgin resin PVC, while the outer layer is PVC coated fabric. Kedermaker also supplies PP, PE and TPO keder options for projects that require different material compatibility or recyclable material choices.
The core gives the keder its shape, while the coated fabric flap allows it to be welded, sewn or attached to a fabric panel.
What Is Keder Used For?
Keder is used when a fabric edge needs to connect with a rail, groove, track or frame. In tent and marquee systems, keder helps connect vinyl tops and sidewalls to structural rails. In signage, plastic welt and keder-style profiles help printed textile graphics lock into aluminum frames. In marine canvas and awning systems, keder helps create a clean, reinforced edge for outdoor fabric installations.
Common Keder Applications
-
Tent and marquee structures
-
Banner and soft signage systems
-
Awning and canopy fabric edges
-

-
Tarpaulins and industrial covers
-
Tensile fabric and membrane structures
-
Custom industrial fabric systems
Why Full-Bond Keder Matters
Traditional line-sealed keder bonds only part of the coated fabric around the core. Full-bond keder uses bonding around the core perimeter, helping create a stronger and more consistent connection between the core and the fabric wrap.
For demanding applications such as tents, awnings, marine canvas and industrial fabric systems, full-bond construction can help improve reliability during rail pulling, installation, removal and outdoor use.
