Finishing square profiles

Hollow square profiles are used in furniture, engineering and construction. The 20×20 and 30×30 mm sections are common standards in metalwork and steel structures.

VINYL-FLEX® square caps fit the profile section closely. They cover all four sharp corners, close the hollow section against moisture and dust, and give the product a finished appearance. Simply push them on without tools or glue.

Use in furniture and industry

The 20×20 mm size suits lighter furniture, such as office desk legs, shelving frames and children’s furniture. It protects floors, covers corners and gives the product a finished look.

The 30×30 mm size suits heavier uses such as industrial tables, shelving systems, machine frames and outdoor steel structures. It is stronger and withstands everyday mechanical wear.

Outdoor use and durability

Both sizes use VINYL-FLEX® material that resists UV, moisture and frost. They suit pergola posts, garden furniture, fences and façade systems without yellowing or becoming brittle after a season outdoors.

Typical uses
