kulmapalkit

Kulmapalkit, a Finnish term for hardware components used to reinforce and stabilize corners of furniture, frames, and light construction, are commonly translated as corner brackets or angle brackets in English. They are typically used to reinforce right-angled joints, such as shelves, cabinet corners, picture frames, and timber frames, contributing to rigidity and effective load transfer between panels.

Most kulmapalkit are metal, often steel or stainless steel, though decorative brass or durable plastic variants exist for lighter or visible applications. They come mainly as L-shaped brackets with two flanges and multiple screw holes, oriented to grip perpendicular members. Sizes, thickness, hole patterns, and finishes vary to suit different loads and aesthetics.

Applications include shelving support, cabinet reinforcement, frame construction, and a variety of DIY carpentry projects. Installation considerations emphasize correct alignment at 90 degrees, predrilling to prevent splitting, and selecting screws or anchors suitable for the backing material. For heavy loads, multiple brackets, longer fasteners, and a backing strip or studs can improve stability. In visible installations, decorative finishes or corrosion-resistant coatings are common.

Retailers categorize kulmapalkit by load rating and material, offering both generic, non-decorative options and decorative variants for furniture and interior design. Although simple in form, these brackets play a practical role in ensuring the structural integrity and longevity of assembled structures.
